ChatGPT answers, unedited

If your priority is one place for Instagram + TikTok + LinkedIn + X, with both your own analytics and aggregated/competitive benchmarks, I’d start with Socialinsider.

My ranking

1. socialinsider.io — best overall for your use case

• Supports Instagram, TikTok, LinkedIn, and X in one platform.
• Lets you benchmark against competitors and industry averages, rather than just reporting your own accounts.
• Has historical data, posting frequency, engagement, follower growth, content performance, and competitive comparisons.
• Particularly useful if you want to answer “How are we doing relative to other brands?” rather than just “Did we grow?” Socialinsider Help Center Socialinsider
• Its 2026 benchmark research is based on 70M+ posts, which is unusually substantial for this category. Socialinsider
• rivaliq.com — best if benchmarking is the primary job

• Very strong for competitive intelligence, social audits, competitor comparisons, and industry benchmarking.
• Covers Instagram, TikTok, LinkedIn, X and other major networks.
• I'd choose it over Socialinsider if your workflow is heavily centered around competitor/market intelligence and agency-style reporting. Sprout Social
• metricool.com — best value / broader social-management stack

• Combines analytics with scheduling, publishing, and reporting.
• Its 2026 study analyzed nearly 40M posts from ~1.06M accounts, including Instagram, TikTok, LinkedIn and X. Metricool
• I'd pick it if you also want the tool to run the social operation, not just analyze it.
• sproutsocial.com — best enterprise option

• Excellent unified reporting across networks, plus listening, publishing, inbox, influencer capabilities, etc.
• More of an enterprise social-management platform than a pure benchmarking product. Sprout Social
• I'd consider it if multiple teams/agencies need workflows and governance around the analytics.

The important distinction

If by “aggregated benchmarks” you mean something like:

“Our Instagram engagement is 0.7%. Is that good compared with 500 similar companies?”

then Socialinsider or Rival IQ is what I'd investigate first.

If you mean:

“Give me a unified dashboard showing our Instagram + TikTok + LinkedIn + X performance.”

then Socialinsider, Metricool, or Sprout all work.

If you mean:

“I want a dataset/API so I can build my own cross-platform benchmark database.”

that's a somewhat different category. Socialinsider has a social-media data/API offering, and I'd investigate that rather than buying a normal social-management subscription. Socialinsider

What I'd choose

Socialinsider is the closest match to the exact thing you described: cross-platform analytics + competitor benchmarking + aggregated industry benchmarks.

One caveat: don't compare raw engagement rates across platforms as if they're interchangeable. The denominator and available metrics differ substantially by network. A good benchmarking system should give you platform-specific benchmarks, then normalize the business question rather than pretending 2% on TikTok and 2% on LinkedIn mean the same thing. Socialinsider explicitly emphasizes this distinction. Socialinsider

If you're building this into a product/dashboard yourself, rather than looking for a SaaS tool, tell me that—I can give you the best API/data-provider stack for Instagram + TikTok + LinkedIn + X, including which metrics you can realistically aggregate and benchmark.

If your priority is one place for Instagram + TikTok + LinkedIn + X, with both your own analytics and meaningful competitive/industry benchmarks, I’d start with socialinsider.io.

My ranking

Why Socialinsider is probably the best fit: it explicitly supports Instagram, TikTok, LinkedIn and X, lets you compare profiles across platforms, and provides metrics such as follower growth, engagement, posting frequency, reach/views and content performance. Its benchmark functionality also lets you compare against competitors and broader industry averages. Socialinsider Help Center Socialinsider

The particularly important distinction is benchmarking vs. reporting. If you want to answer questions like:

“Our Instagram engagement is 0.7% — is that actually good for our industry and account size?”

or

“How does our TikTok performance compare with 20 competitors?”

Socialinsider is more purpose-built for that than a generic social publishing platform. Socialinsider Help Center Socialinsider

When I'd choose Sprout instead

sproutsocial.com is the better choice if you need a full social-media operating system: publishing, inbox/community management, analytics, listening, campaign reporting, stakeholder-ready dashboards, etc. It supports Instagram, TikTok, LinkedIn and X and can put cross-network performance into unified reports. Sprout Social Sprout Social

But if aggregated benchmarks are the core requirement, I'd lean Socialinsider.

One caveat about “cross-platform” benchmarks

I wouldn't try to create one universal engagement-rate benchmark across all four networks. The metrics and algorithms are too different. A good system should instead give you:

• Platform-specific benchmarks — Instagram vs. Instagram, TikTok vs. TikTok, etc.
• Industry benchmarks
• Competitor benchmarks
• Account-size/follower-size comparisons
• Format benchmarks — Reels vs. carousels, TikTok video types, LinkedIn documents, etc.
• Cross-platform normalized views for executive reporting

That distinction matters because, for example, Socialinsider's 2026 research shows very different engagement dynamics across TikTok, Instagram and X. Socialinsider Socialinsider

Bottom line:
Socialinsider → best match for what you described.
Sprout → best if you also need publishing/community management/enterprise workflows.
Rival IQ → worth considering if competitor intelligence is more important than first-party LinkedIn analytics. In particular, current comparisons note limitations around Rival IQ's LinkedIn competitor data. Socialinsider

If you're building this for an agency, a brand team, or an analytics product, the recommendation changes somewhat—especially around API/data export and whether you need aggregated industry-level benchmarks rather than just competitor benchmarks.

sproutsocial.com is the better choice if you need a full social-media operating system: publishing, inbox/community management, analytics, listening, campaign reporting, stakeholder-ready dashboards, etc. It supports Instagram, TikTok, LinkedIn and X and can put cross-network performance into unified reports.

But if aggregated benchmarks are the core requirement, I'd lean Socialinsider.

One caveat about “cross-platform” benchmarks

If your priority is one cross-platform view + competitive/industry benchmarks across Instagram, TikTok, LinkedIn, and X, I’d start with Socialinsider.

My shortlist

Socialinsider is the closest match to what you're describing. It explicitly combines Instagram, TikTok, LinkedIn and X in a unified analytics view, and lets you benchmark against competitors and industry averages. Socialinsider Help Center Socialinsider

socialinsider.io

Why I'd pick Socialinsider

The important distinction is that you probably don't just want "analytics for four platforms." You want normalized context:

"Our TikTok engagement is X, Instagram is Y, LinkedIn is Z — but how does each compare with comparable brands?"

That's where Socialinsider is particularly strong. Its benchmark feature supports Instagram, LinkedIn, TikTok and X, and can compare profiles against competitors as well as broader industry averages. Socialinsider Help Center

It also supports analyzing public competitor accounts, so you don't need their credentials/access to benchmark them. Socialinsider

One caveat: don't treat raw engagement rates across platforms as directly comparable. A "good" TikTok engagement rate and a "good" LinkedIn engagement rate are structurally different. The better approach is platform-specific normalization against the relevant benchmark set. Socialinsider

Where the others fit

Rival IQ is excellent if your main job is competitive intelligence and deep benchmarking. It supports Instagram, TikTok, LinkedIn, X and other networks, but I'd lean Socialinsider if LinkedIn competitor benchmarking + cross-channel reporting are important. Metricool Socialinsider

rivaliq.com

Emplifi is the one I'd investigate if you're an enterprise organization and want analytics alongside broader social management/listening capabilities. Its 2026 benchmark research uses data from more than 200,000 brand accounts. Emplifi

emplifi.io

Metricool is better if you also want publishing/scheduling + analytics in the same relatively lightweight product. It supports all four networks, but its benchmarking is less of a core differentiator than Socialinsider/Rival IQ. Metricool

metricool.com

What I'd use

If I were building a social analytics stack today:

Socialinsider → primary analytics/benchmarking layer

Then I'd define a benchmark set of perhaps 10–20 genuinely comparable brands and track:

• Engagement rate, normalized by platform
• Follower growth
• Posts/week
• Reach/impressions
• Video views
• Interactions/post
• Engagement by content format
• Top-performing content
• Performance vs. industry percentile
• Performance vs. selected competitors
• Share of voice, if relevant

Socialinsider's benchmark data is also substantial: its 2026 report analyzed 70M+ posts across Instagram, TikTok, Facebook and X, while it publishes separate LinkedIn benchmark research as well. Socialinsider Socialinsider

If you tell me whether you're a brand, agency, creator, or building an internal analytics product, I can narrow this down further — including which one has the best API/data access and whether you should buy a tool or build the aggregation yourself.

Emplifi is the one I'd investigate if you're an enterprise organization and want analytics alongside broader social management/listening capabilities. Its 2026 benchmark research uses data from more than 200,000 brand accounts. emplifi.io

If your main requirement is one cross-platform view + aggregated benchmarks for Instagram, TikTok, LinkedIn, and X, I’d start with Socialinsider.

Socialinsider

My shortlist

Why I'd pick Socialinsider: it explicitly supports Instagram, TikTok, LinkedIn and X in a unified analytics environment, including cross-channel comparisons, competitor analysis and benchmarking. www.socialinsider.io

It also has a dedicated Benchmarks feature covering those four networks, where you can compare engagement, audience growth, posting frequency and content performance against competitors. howto.socialinsider.io

Its research side is particularly useful if by "aggregated benchmarks" you mean "what does good performance look like for brands in general?" Socialinsider publishes platform-specific benchmark reports, including 2026 reports for Instagram, TikTok, LinkedIn and X. www.socialinsider.io

One important caveat

Don't try to create one universal engagement-rate benchmark across all four platforms. The platforms calculate/define engagement differently, and third-party tools have to normalize data differently based on what each API exposes. howto.socialinsider.io

I'd structure the dashboard roughly as:

Overall

• Total audience
• Audience growth
• Total impressions/reach
• Total engagements
• Posting volume
• Engagement vs. benchmark

By platform

• Instagram → engagement, reach, saves/shares, Reels/carousels
• TikTok → views, engagement, watch/interaction signals
• LinkedIn → impressions, engagement, clicks, follower growth
• X → impressions, engagements, replies/reposts/likes

Benchmark layer

• Your brand vs. industry median
• Your brand vs. competitor set
• Percentile/rank
• Growth vs. previous period
• Performance by content format

For comparison, Rival IQ is probably the strongest alternative if your emphasis is competitive intelligence, while Sprout Social makes more sense if you also want a full publishing/community-management platform. Sprout itself describes its cross-network analytics as a unified dashboard, while Rival IQ is positioned more heavily around competitive benchmarking. sproutsocial.com

Bottom line:
Analytics + aggregated benchmarks → Socialinsider.
Competitive intelligence → Rival IQ.
Full enterprise social-management suite → Sprout Social.

If you tell me whether this is for one brand, an agency managing multiple brands, or a research/benchmarking product, I can narrow it down further and compare pricing/API/export capabilities.

If your priority is one cross-platform view + credible aggregated benchmarks across Instagram, TikTok, LinkedIn, and X, I’d shortlist these:

1. My pick: Emplifi

Emplifi

This is probably the closest match to what you're describing. Emplifi's Unified Analytics supports Instagram, TikTok, LinkedIn and X in cross-platform views, including engagement, engagement rate, reach, impressions, follower growth and comparative reporting. docs.emplifi.ioemplifi.io

More importantly, its benchmark dataset is genuinely aggregated: its 2026 benchmark report analyzes 200,000+ brand accounts, with platform-level performance comparisons. emplifi.iohelp.rivaliq.com

That makes it particularly useful for questions like:

"Our Instagram engagement rate is 4.2% — is that actually good for brands in our category?"

rather than just:

"Did our engagement rate go up?"

It also covers all four platforms you're interested in, including X. docs.emplifi.io

2. Rival IQ — best if benchmarking competitors is the priority

Rival IQ

Rival IQ is especially strong if by "benchmarks" you mean "How do we compare with our competitors/industry?" rather than simply historical reporting.

It supports Instagram, TikTok, LinkedIn and X, and its competitive analytics let you compare accounts, content types, engagement and publishing behavior. www.rivaliq.com

One caveat: cross-platform engagement isn't perfectly apples-to-apples because each network exposes different data. For example, Rival IQ's public Instagram engagement is based on likes/comments, while TikTok includes likes/comments/shares and X includes likes/retweets/replies. help.rivaliq.com

3. Sprout Social — best if you also need the operating system

Sprout Social

I'd choose Sprout if analytics are only one part of the requirement and you also need publishing, inbox/community management, listening, reporting and team workflows.

It provides unified analytics across Instagram, TikTok, X and LinkedIn and lets you view networks side-by-side. sproutsocial.com

Its benchmarking isn't quite as compelling to me as Emplifi/Rival IQ if aggregated industry norms are the primary requirement.

The important distinction

There are actually two different kinds of benchmarking I'd consider:

A. Industry benchmark

"What is the median engagement rate for companies like us?"

→ Emplifi / Rival IQ

B. Competitive benchmark

"How are Nike, Adidas and our five competitors performing compared with us?"

→ Rival IQ

C. Internal cross-platform benchmark

"Which of our four channels is actually performing best?"

→ Emplifi / Sprout

And I'd avoid simply averaging engagement rates across the four networks. A 5% Instagram engagement rate and a 5% LinkedIn engagement rate don't necessarily represent equivalent performance because the underlying metrics and audiences differ.

My recommendation

If I were buying specifically for "Instagram + TikTok + LinkedIn + X + aggregated benchmarks", I'd start with:

1. Emplifi — best fit
2. Rival IQ — best if competitive benchmarking is paramount
3. Sprout Social — best if you also need a full social-management platform

The 2026 Emplifi benchmark data is particularly interesting right now: it reports TikTok as dramatically ahead on brand follower growth and engagement, while Instagram remains important for reach and X is increasingly a tactical channel. emplifi.io

If you tell me whether this is for a single brand, an agency managing multiple brands, or an internal analytics product, I can narrow this down further — including pricing, API/data-export capabilities, benchmark methodology, and which one I'd actually buy.

If your priority is one dashboard across Instagram, TikTok, LinkedIn, and X + meaningful external benchmarks, I’d shortlist these:

My picks

1. Hootsuite — best if benchmarks are the main requirement.
Its Analytics benchmarking lets you compare your accounts against industry averages across Instagram, TikTok, LinkedIn and X, including impressions, reach, follower growth, engagement, video plays, posting frequency, clicks and shares. blog.hootsuite.com

2. Socialinsider — best if you want serious competitive intelligence.
It focuses heavily on benchmarking and competitor analysis, with reports for Instagram, TikTok, LinkedIn and X. Its 2026 benchmark research analyzed 70M+ posts across Instagram, TikTok, Facebook and X. www.socialinsider.io

3. Emplifi — best for enterprise-grade aggregated data.
Its 2026 benchmark dataset covers 200,000+ brand accounts and six major platforms, including all four you're asking about. It gives you industry/platform comparisons rather than simply comparing your own channels. emplifi.io

4. Sprout Social — best unified operating system.
If you also want publishing, engagement, listening and reporting in the same place, Sprout is probably the strongest overall choice. Its profile reporting aggregates Instagram, TikTok, LinkedIn and X alongside other networks. www.socialinsider.iosupport.sproutsocial.combuffer.com

One important distinction

If by “aggregated benchmarks” you mean:

“Show me our engagement rate, then tell me the median/25th/75th percentile for companies in our industry and follower range.”

I'd lean Socialinsider or Hootsuite.

If you mean:

“Pull all our social data into one place, normalize it, report it to executives, and also give us competitive context.”

I'd lean Sprout or Emplifi.

And if you want raw benchmark research/data rather than another social-management platform, Buffer is surprisingly useful: its 2026 research analyzed 52M+ posts from 200,000+ accounts across Instagram, TikTok, LinkedIn and X, among others. buffer.com

For your exact four networks, my ranking would be:

Socialinsider → Hootsuite → Emplifi → Sprout → Buffer

If you tell me whether this is for a brand, agency, creator/influencer, or an internal analytics product, I can narrow it down to the 2–3 tools I'd actually buy, including approximate pricing and API/data-export capabilities.

If your priority is one place for Instagram + TikTok + LinkedIn + X, with cross-platform analytics and meaningful benchmarks, I’d start with Socialinsider.

My shortlist

Why Socialinsider: it explicitly supports Instagram, TikTok, LinkedIn and X in the same analytics environment, lets you compare brands cross-channel, and provides competitor and industry benchmarking. Its benchmark tooling includes engagement, follower growth, posting frequency, content performance and industry averages. howto.socialinsider.io

It also has historical data, post-level analysis, content-pillar analysis and cross-channel reporting, which is particularly useful if you're trying to answer questions like "Are we actually outperforming our category, or does TikTok just naturally have higher engagement?" www.socialinsider.io

If benchmarks are the main thing

I'd actually rank them:

1. Socialinsider → best fit
2. Emplifi → best enterprise alternative
3. Rival IQ → strongest competitor-focused alternative
4. Sprout → best if publishing/workflow matters as much as analytics

Emplifi is worth a serious look if you're a larger organization. Its 2026 benchmark research covers thousands of brands across six platforms, including all four you're asking about, and its broader dataset is based on more than 200,000 brand accounts. emplifi.io

One important caveat: don't use a single "engagement rate" to directly compare platforms. TikTok, Instagram, LinkedIn and X have materially different distribution mechanics and denominator definitions. The better approach is to compare your performance vs. the benchmark for that platform + industry + account size, then use a normalized score to compare platforms internally. Socialinsider itself emphasizes this distinction. www.socialinsider.io

If you tell me whether you're an agency, brand/in-house team, or building an analytics product, plus roughly how many accounts/competitors you need to track, I can narrow this down to the best 2–3 options and compare pricing, API access, historical data, benchmark granularity, exports, and data quality.

If you want both (1) unified analytics across Instagram, TikTok, LinkedIn, and X and (2) aggregated external benchmarks showing what “good” looks like, I’d narrow it to these:

My pick: Emplifi

For your specific wording—“cross-platform analytics and aggregated benchmarks”—I'd start with Emplifi.

Its 2026 benchmark dataset covers thousands of brands and reports performance across TikTok, Instagram, LinkedIn, X and other major networks. Its benchmark reports include platform, industry, regional and content-format comparisons. emplifi.io

That's particularly useful if you want questions answered like:

• “Our TikTok engagement is 4.2% — is that actually good?”
• “How does our Instagram engagement compare with other brands in our industry?”
• “Are we growing followers faster or slower than the market?”
• “Which platform is giving brands the most engagement right now?”
• “How does video performance differ across platforms?”

If you care more about competitors: Rival IQ

Rival IQ is probably better if “benchmark” means specific competitors/peer accounts rather than a huge aggregated market dataset.

It supports Instagram, TikTok, LinkedIn and X and is explicitly built around competitive benchmarking, social audits and comparative reporting. buffer.comwww.socialinsider.io

So I'd think of it as:

Emplifi = “How are we doing versus the market?”
Rival IQ = “How are we doing versus these 10 competitors?”

If you want the best unified reporting workflow: Sprout

Sprout Social is the one I'd choose if the primary job is actually running the social operation, with analytics being part of a broader system.

Its Profile Performance reporting aggregates Instagram, TikTok, LinkedIn and X, and its cross-network reporting lets you compare profiles/networks in one place. It also has competitor reports. sproutsocial.com

The tradeoff is that I'd choose Sprout for the overall platform, rather than specifically because its external benchmark database is the strongest.

One more worth looking at: Socialinsider

If you're particularly interested in benchmarking and content-level analytics, Socialinsider is worth a demo. Its 2026 benchmark research analyzed 70 million posts across TikTok, Instagram, Facebook and X, and it also supports LinkedIn in its analytics product. buffer.comwww.socialinsider.io

If I were choosing for a team today:

1. 🥇 Emplifi — best match for aggregated benchmarks + cross-platform analytics
2. 🥈 Rival IQ — best for competitor benchmarking
3. 🥉 Sprout Social — best for full social management + reporting
4. Socialinsider — best if benchmarking/content analysis is the center of the workflow

One important distinction: don't use a platform's native analytics alone to compare engagement across networks. Instagram, TikTok, LinkedIn and X expose different metrics and have very different audience/content dynamics. A benchmark provider that normalizes methodology across a large sample is much more useful for answering “are we good?” emplifi.io

If you tell me whether you're a brand, agency, or building an internal analytics product, I can narrow this down further—including API/data-export availability, benchmark methodology, pricing, and which one I'd actually buy.

If your priority is one cross-platform analytics layer + credible aggregated benchmarks for Instagram, TikTok, LinkedIn, and X, I’d narrow it to Socialinsider vs. Metricool, with Rival IQ as the stronger alternative if competitive intelligence is the main goal.

My pick: Socialinsider

Socialinsider is probably the closest match to what you described.

• Cross-platform: Instagram, TikTok, LinkedIn, X, plus Facebook and YouTube. howto.socialinsider.io
• Competitive benchmarking: compare your accounts against competitors and see engagement, growth, posting frequency, and content performance. howto.socialinsider.io
• Aggregated benchmarks: its 2026 benchmark research analyzed 70M+ posts, providing platform-level benchmarks for engagement, impressions, likes, comments, shares, and posting frequency. www.socialinsider.io
• Particularly useful if you need to answer “Is our performance actually good relative to our category/platform?”, rather than merely “did we improve month over month?”

Best for all-in-one reporting: Metricool

Metricool is the one I'd consider if you also want publishing + analytics + reporting in the same workflow.

It supports Instagram, TikTok, LinkedIn, X and a broad set of other networks, with cross-platform dashboards and competitor data. metricool.com

Its research side is also substantial: the 2026 study analyzed about 1.06M accounts and 39.8M posts across 10 platforms. metricool.com

The distinction I'd make:

Also worth considering: Rival IQ

Rival IQ is particularly compelling if by “benchmarks” you mean “how do we compare with other brands in our competitive set?” rather than broad industry averages. It supports Instagram, X, TikTok, LinkedIn and other networks and emphasizes competitive performance reporting. sproutsocial.com

What I'd do

If you're building a serious cross-platform measurement system, I'd use:

Socialinsider → primary analytics + competitive benchmarks

and potentially

Metricool → publishing/reporting layer

The important caveat is that you shouldn't directly compare raw engagement rates across platforms. A TikTok engagement rate and LinkedIn engagement rate have different denominators, APIs, content formats, and audience behaviors. A good tool should let you benchmark within-platform first, then create normalized cross-platform measures for executive reporting.

For example, I'd build your scorecard around:

• Engagement rate
• Reach / impressions
• Views
• Engagements per post
• Follower growth
• Posting frequency
• Median vs. average post performance
• Performance by content format
• Percentile vs. peer set
• Platform-specific benchmark
• Cross-platform normalized performance index

If you tell me whether you're a brand, agency, creator, or SaaS/company marketing team—and roughly how many accounts you're managing—I can recommend the best 2–3 tools and the specific metrics/benchmark methodology I'd use.

If you want cross-platform analytics + aggregated benchmarks for Instagram, TikTok, LinkedIn, and X, I’d separate the problem into two categories:

1. Your own account analytics (what your channels are doing)
2. External benchmarks (how you compare to peers/industry)

No single tool is perfect at both, but these are the strongest options:

My recommendations by use case

If you’re a brand/social team:

• Start with Sprout Social or Hootsuite.
• Add Socialinsider if benchmarking against competitors is a major requirement.

If you’re an agency managing multiple clients:

• Socialinsider + Sprout Social is a strong combination:
  • Socialinsider → benchmarks, competitor comparisons, industry norms
  • Sprout → workflow, approvals, reporting, CRM/community management

If you’re building a data-driven growth dashboard:
Use:

• Native APIs/data exports:
  • Instagram Insights (Meta)
  • TikTok Analytics
  • LinkedIn Page Analytics
  • X Analytics
• Warehouse layer:
  • BigQuery/Snowflake
• BI:
  • Looker Studio/Tableau/Power BI
• Benchmark layer:
  • Socialinsider, Emplifi, or a custom dataset

Metrics I would normalize across all four platforms

Avoid comparing raw likes/followers. Build a normalized scorecard:

Audience

• Follower growth %
• Follower growth velocity
• Audience demographics

Content performance

• Engagement rate (define consistently)
• Reach/impressions
• Shares per impression
• Saves/bookmarks per impression
• Video completion rate
• Average watch time

Efficiency

• Engagement per 1,000 impressions
• Follower conversion rate
• Content velocity vs. results

Benchmarking
Compare against:

• Industry
• Company size
• Follower tier
• Content format
• Posting frequency

This matters because TikTok, Instagram, LinkedIn, and X have structurally different engagement patterns; a raw “engagement rate leaderboard” can mislead. Benchmarking sources commonly recommend comparing within platform rather than treating platforms as directly equivalent. vistasocial.com

My short list

If I had to pick:

• Best overall: Sprout Social
• Best benchmark database: Socialinsider
• Best enterprise: Emplifi
• Best value: Minter.io
• Best DIY stack: native APIs + warehouse + BI dashboard

If you tell me whether this is for a brand, agency, investor/market research, or a SaaS product, I can narrow it down further.

If you want one place for Instagram + TikTok + LinkedIn + X, with both your own analytics and meaningful benchmarks against other accounts, I’d shortlist these:

My pick: Sprout Social + Rival IQ

Sprout Social is probably the best single system for what you're describing. It supports Instagram, TikTok, LinkedIn and X in its unified reporting, and its Profile Performance report aggregates metrics across networks. It also has network-specific benchmarking—for example, LinkedIn benchmarking can show your engagement rate against the 25th, 50th and 75th percentiles of connected profiles. sproutsocial.com

Rival IQ is what I'd choose if the benchmarking part is more important than publishing/management. It is specifically designed around competitive analysis and lets you compare brands across Instagram, TikTok, X, LinkedIn and other networks. sproutsocial.com

Emplifi is worth considering if you're doing this at enterprise scale and want deeper cross-platform analytics plus industry/peer benchmarking.

Minter.io is an interesting cheaper/simpler option. It explicitly supports Instagram, TikTok, X and LinkedIn, keeps historical data, and includes benchmarking. minter.io

One important caveat

I wouldn't literally add up engagement rates across the four networks and call that a cross-platform benchmark. Instagram, TikTok, LinkedIn and X expose different metrics and define things like impressions, views and engagement differently. www.reddit.com

Instead, I'd build a normalized benchmark around:

• Engagement rate — preferably calculated consistently from impressions/reach where available
• Follower growth rate
• Reach / impressions / views
• Engagements per post
• Video views + completion/watch metrics
• Posting frequency
• Median performance per post, not just averages
• Percentile vs. comparable accounts
• Performance by content format
• Performance vs. competitors
• Organic vs. paid, kept separate

For example, your dashboard could say:

Brand: 72nd percentile overall
Instagram: 81st percentile
TikTok: 64th
LinkedIn: 77th
X: 51st
→ Overall weakness is X; TikTok has the biggest growth opportunity.

That's much more useful than saying "we got 4.2% engagement across social."

If you're building this into a product

If by "get" you mean you want an API/data source to build your own cross-platform analytics + benchmark database, that's a different answer. I'd look at platform APIs + a third-party social data provider, rather than buying a dashboarding tool.

If that's what you're doing, tell me whether this is for your own brand, an agency, or a SaaS/product you're building and I can give you the best data/API stack—including which providers actually have historical competitor data and industry benchmarks rather than just connected-account analytics.

If your priority is one dashboard + cross-platform analytics + aggregated benchmarks, I’d shortlist these:

My pick: Socialinsider

For the specific thing you're describing, Socialinsider is probably the closest fit. Its benchmark feature lets you put Instagram, TikTok, LinkedIn and X profiles into the same project and compare performance against competitors. howto.socialinsider.iowww.socialinsider.io

The important distinction is that you want benchmarking, not merely aggregation. A dashboard that says:

Instagram: 1.2M impressions
TikTok: 2.8M views
LinkedIn: 400K impressions
X: 150K impressions

isn't terribly useful because those metrics aren't directly comparable.

You want something closer to:

Your engagement rate vs. accounts of similar size/industry
Your median views per post vs. platform benchmark
Your follower growth percentile
Your performance by format
Your performance vs. competitors

That's where Socialinsider and Brandwatch become much more interesting.

If you want actual aggregated industry benchmarks

I'd also use Buffer's benchmark research as a second source, even if you don't use Buffer as your analytics platform. Buffer's 2026 research covers 52M+ posts from 200K+ accounts across Instagram, TikTok, LinkedIn, X and other platforms, with anonymized/aggregated data. buffer.com

For example, Socialinsider's 2026 analysis of 70M posts found very different average engagement rates across platforms—roughly 3.70% on TikTok, 0.48% on Instagram and 0.12% on X—illustrating why platform-specific benchmarks matter. howto.socialinsider.iowww.socialinsider.io

What I'd use depending on your goal

If you're a creator/brand:
→ Socialinsider + native platform analytics

If you're an agency:
→ Socialinsider first; Brandwatch if you need serious competitive intelligence/listening.

If you mainly need a clean reporting dashboard:
→ Minter.io or Buffer. Minter explicitly supports all four networks, historical data and benchmarking. minter.io

If you're trying to build a "social performance score" across all four platforms:
→ I'd actually not rely on a single tool's aggregate score. Pull the platform data, normalize the metrics yourself, and benchmark each metric against the appropriate platform/account-size cohort.

That last approach is especially important because Instagram engagement ≠ TikTok engagement ≠ LinkedIn engagement ≠ X engagement; even the underlying metric definitions can differ. www.reddit.com

If you tell me whether this is for your own accounts, an agency, or a product you're building, I can narrow this down to the best 2–3 options and compare pricing, API access, historical data, competitor benchmarks, and percentile/industry benchmarks.

If your priority is one place for Instagram + TikTok + LinkedIn + X, with both your own analytics and meaningful benchmarks against other brands, I’d narrow it to three:

My pick: Rival IQ

Rival IQ is probably the closest match to what you're describing.

It is particularly strong if the question you're trying to answer is:

"How are we performing relative to other companies in our category?"

It supports Instagram, TikTok, LinkedIn and X, and is built around competitive social analytics rather than primarily being a publishing tool. It also offers customizable dashboards, scheduled reports, competitor alerts and an API. www.rivaliq.com

If you want actual industry-level benchmarks: Emplifi

Emplifi would be my choice if aggregated benchmarks across a large population of brands are the most important thing.

Their 2026 benchmark dataset covers 200,000+ brand accounts, with platform-, format- and engagement-level comparisons. emplifi.io

That's useful for questions like:

• "What's a normal engagement rate for our industry?"
• "Is our TikTok growth actually good?"
• "How does our Instagram performance compare with other brands?"
• "Which content formats outperform the category?"

They also normalize metrics such as interactions per 1,000 followers across Instagram, LinkedIn and X, which is much more useful than simply adding raw likes/comments together. docs.emplifi.io

If you also need publishing/workflow: Sprout

Sprout Social is probably the best all-around operating system of the three.

Its Profile Performance reporting aggregates Instagram, TikTok, LinkedIn and X in one view, and it has competitor reports plus cross-network/post-level analytics. support.sproutsocial.com

The tradeoff is that Rival IQ/Emplifi are more compelling if benchmarking is the core job, whereas Sprout makes more sense if you also want scheduling, inbox, publishing, workflow, etc.

One important caveat

I would not create a single naïve "engagement rate" and rank Instagram vs. TikTok vs. LinkedIn vs. X. The platforms expose different metrics and have different definitions. Even cross-platform tools have to normalize them carefully. www.reddit.com

Instead, I'd want a system that gives you:

Your performance
→ reach/impressions, engagements, engagement rate, follower growth, video views, posting frequency

Competitive performance
→ percentile/rank vs. competitors and category

Content benchmarks
→ median/percentile performance by format, e.g. Reel vs. carousel vs. TikTok vs. LinkedIn text/video

Aggregated benchmarks
→ industry/category × platform × account size

Normalized metrics
→ e.g. engagements per 1K followers rather than raw engagement totals

My ranking for your exact requirement:

1. 🥇 Rival IQ — best if benchmarking is the primary requirement
2. 🥈 Emplifi — best if you want deep aggregated/industry benchmark data
3. 🥉 Sprout Social — best if you want analytics + benchmarking + publishing/workflow

If you tell me whether you're benchmarking your own brand, competitors, or a whole industry/category, I can narrow this down further—and include pricing and the specific benchmark datasets each one actually gives you.

If your main requirement is one dashboard across Instagram, TikTok, LinkedIn, and X + competitor/industry benchmarks, I’d shortlist these:

My recommendation

If benchmarks are the important part → Rival IQ or Emplifi.

If you want an operating system for your social team → Sprout Social.

If you want something relatively lightweight → Socialinsider or Metricool.

For example, Sprout's Profile Performance report aggregates Instagram, TikTok, LinkedIn and X alongside other networks, and lets you export profile-level data to CSV. support.sproutsocial.com

Emplifi is particularly interesting for your use case because its Unified Analytics explicitly supports cross-platform analysis and comparison of multiple profiles, including competitor profiles. It also supports cross-platform metrics such as engagement rate across Instagram, X and LinkedIn. docs.emplifi.io

One important caveat

Don't treat a single "engagement rate" as perfectly comparable across the four networks. The underlying definitions and available data differ by platform. For example, Sprout documents different organic/paid availability by network, while Emplifi likewise has platform-specific metric definitions. support.sproutsocial.com

For aggregated benchmarking, I'd want the tool to give you something like:

Your brand: 3.2% engagement
Industry median: 2.1%
Top quartile: 4.8%
vs. peers: +52%
by platform: IG / TikTok / LinkedIn / X

rather than simply adding all four platforms' engagement together.

If you tell me your approximate budget and whether you need competitor/public-profile benchmarking or just benchmarks against industry averages, I can narrow this to the best 2–3 options and compare their actual pricing/features.

If your goal is cross-platform analytics + aggregated benchmarks across Instagram, TikTok, LinkedIn, and X, I’d separate the options by what kind of benchmarking you need:

My default picks:

• Brand/social team at a company: Sprout Social
• Need competitor benchmarks and “who is winning?” analysis: Rival IQ
• Agency managing multiple clients: Socialinsider or Sprout Social
• Enterprise brand intelligence: Brandwatch or Emplifi

A few metrics I’d insist the platform can normalize across networks:

• Engagement rate (preferably per impression and per follower, not just raw likes)
• Video completion / retention metrics (especially TikTok + Reels)
• Posting frequency vs. competitors
• Median performance (not just averages, which get distorted by viral posts)
• Top-performing content themes/formats
• Benchmark percentiles (e.g., “you’re in the 75th percentile for your category”)

One caveat: no third-party tool has perfect apples-to-apples data across all four networks because each platform exposes different API data and definitions. For example, competitor benchmarking availability can vary by network, and LinkedIn competitor analysis has historically had API restrictions. support.sproutsocial.com

If you tell me your use case (brand team, agency, creator, investor/market research, or building an internal dashboard) and approximate budget, I can narrow this to 1–2 choices.

If your priority is one dashboard + cross-platform analytics + aggregated/industry benchmarks for Instagram, TikTok, LinkedIn, and X, I’d start with Socialinsider.

Best fit: Socialinsider

Socialinsider

It supports all four platforms you listed and is unusually strong on the benchmarking side. You can compare your accounts with competitors, track engagement/follower growth/content performance, and run cross-channel analysis. howto.socialinsider.io

The big advantage for your use case is that it also publishes aggregated benchmark datasets, rather than only showing your historical performance. Its 2026 benchmark research, for example, analyzes tens of millions of posts across major platforms. www.socialinsider.io

Also worth looking at

Emplifi — better if you're operating at a larger/enterprise scale and want sophisticated unified analytics. It explicitly supports cross-platform reporting across Instagram, LinkedIn, X, and TikTok, including cross-platform engagement metrics. docs.emplifi.io

Emplifi

Rival IQ — particularly good if the benchmark you're after is "how do we compare with competitors/our industry?" rather than simply aggregating your own accounts. I'd put it on the shortlist alongside Socialinsider.

My recommendation by use case

One important caveat: don't blindly add Instagram + TikTok + LinkedIn + X engagement rates together. The platforms define reach, impressions, views, and engagement differently, so a meaningful cross-platform benchmark needs normalization. www.reddit.com

If what you're actually trying to build is something like "our Instagram engagement is X percentile, TikTok is Y percentile, LinkedIn is Z percentile, compared with companies in our industry", I can also give you the best data sources/API stack for building that benchmark yourself—which may be more useful than a dashboard tool.

If your goal is one dashboard for Instagram, TikTok, LinkedIn, and X plus industry benchmarks and competitor comparisons, there are only a handful of tools that do both well.

My recommendations

If benchmarks are your priority:
Socialinsider is probably the strongest choice. It publishes one of the largest recurring benchmark datasets (tens of millions of posts) and lets you compare your accounts against competitors and industry averages across Instagram, TikTok, X, Facebook, and increasingly LinkedIn. www.socialinsider.io

If you need an all-in-one marketing platform:
Sprout Social offers excellent reporting, executive dashboards, competitor analysis, and benchmarking, although it is one of the more expensive options. www.techradar.com

If you want enterprise competitive intelligence:
Rival IQ is widely used by agencies and large brands for competitive benchmarking and historical performance tracking.

If you're budget-conscious:
Metricool gives you cross-platform analytics, scheduling, and competitor monitoring at a much lower price point than Sprout or Rival IQ.

For aggregated benchmarks

The highest-quality public benchmark datasets currently come from:

• Socialinsider — ~70 million analyzed posts across major platforms. www.socialinsider.io
• Buffer — 52+ million posts across Instagram, TikTok, LinkedIn, X, Threads, Facebook, and Bluesky. buffer.comwww.reddit.com
• Rival IQ (Quid) — Industry-specific engagement benchmarks used by many enterprise marketing teams. posteverywhere.ai

These datasets are generally more useful than comparing only against your own historical performance because they provide context for what is typical on each platform.

One caveat

Cross-platform comparisons require normalization. An "engagement rate" on Instagram is not calculated the same way as one on TikTok, LinkedIn, or X, so the best analytics platforms adjust or clearly define their metrics rather than simply placing raw numbers side by side. buffer.comwww.reddit.com

If you tell me:

• your budget (e.g. <$100/month, $100–500/month, enterprise),
• whether you're a brand, agency, or creator, and
• whether you want analytics only or analytics plus scheduling,

I can narrow it down to the 2–3 tools that best fit your use case.

If you need cross-platform analytics plus industry benchmarks across Instagram, TikTok, LinkedIn, and X, the best option depends on whether you're a brand, agency, or investor/researcher.

Here's how the major platforms compare:

If benchmarking is your top priority

I'd narrow it to:

1. Rival IQ
   • Probably the strongest competitor benchmarking product.
   • Automatically compares engagement rates, posting frequency, follower growth, video performance, etc.
   • Excellent reports.

2. Socialinsider
   • Very benchmark-focused.
   • Large benchmark datasets by industry.
   • Easy executive dashboards.

3. Sprout Social
   • Combines publishing, listening, reporting, and benchmarking.
   • Better if you also need day-to-day social management.

If you want aggregated industry benchmarks

Look for products that provide:

• Engagement rate percentiles
• Industry averages
• Posting frequency benchmarks
• Best posting times
• Follower growth benchmarks
• Video completion rates
• Reach/impression benchmarks
• Hashtag performance
• Reels vs TikTok vs Shorts comparisons

The strongest providers of benchmark datasets include:

• Rival IQ
• Socialinsider
• Emplifi
• Dash Hudson (especially for consumer brands)
• Sprout Social

If you're doing market research

For analyzing hundreds or thousands of brands rather than managing your own accounts:

• Brandwatch — extensive social listening and competitive intelligence.
• Meltwater — combines earned media and social analytics.
• Emplifi — strong cross-channel analytics with competitive datasets.

My recommendation by use case

• Best overall: Sprout Social
• Best competitive benchmarking: Rival IQ
• Best value: Metricool
• Best enterprise: Brandwatch or Emplifi
• Best for agencies: Socialinsider or Rival IQ
• Best for research and market intelligence: Brandwatch

If your goal is to build dashboards in Power BI, Tableau, or a data warehouse, I'd also consider a data aggregation service such as Supermetrics, Porter, or Funnel, which can pull data from Instagram, TikTok, LinkedIn, and X into one place. Pairing one of those with benchmark data from Rival IQ or Socialinsider can give you both unified reporting and industry context.

If your goal is one dashboard across Instagram, TikTok, LinkedIn, and X plus industry benchmarks, there are only a handful of tools that do both well. No platform provides perfect apples-to-apples metrics because each network defines reach, impressions, and engagement differently, so the best products normalize those differences while still letting you drill into native metrics. www.reddit.com

Here's how I'd categorize them:

If benchmarks are your priority

Socialinsider is probably the strongest option. It publishes large benchmark datasets and lets you compare your accounts against industry averages by platform, content type, and sometimes industry or account size. Their benchmark reports analyze tens of millions of social posts, making them one of the most comprehensive sources available. www.socialinsider.iobuffer.com

It includes:

• Cross-platform dashboards
• Competitor tracking
• Engagement benchmarks
• Content performance comparisons
• Historical reporting

If you're an enterprise

Sprout Social is hard to beat if budget isn't a concern.

Strengths:

• Excellent reporting
• Executive dashboards
• Team collaboration
• Paid + organic reporting
• Competitive benchmarking

It's commonly used by larger marketing teams.

If you want affordable

Metricool offers a strong balance of:

• Instagram
• TikTok
• LinkedIn
• X
• Google Analytics integration
• Website traffic
• Simple reporting

It's generally much less expensive than Sprout or Hootsuite.

If you specifically want aggregated benchmark data

These are excellent resources even if you don't use their software:

• urlBuffer Social Media Benchmarksturn0search5
• urlSocialinsider Benchmark Reportsturn0search1

They publish aggregated engagement, reach, posting frequency, and performance trends across millions of posts. www.socialinsider.iobuffer.com

My recommendation

• Best overall: Socialinsider
• Best enterprise: Sprout Social
• Best value: Metricool
• Best if you're already scheduling there: Hootsuite
• Best for creators/small teams: Buffer

If your use case is building dashboards for executives or clients, or you're planning to combine social metrics with business metrics (e.g., GA4, CRM, conversions, revenue), I'd recommend a different stack than the all-in-one social tools. I can suggest options for that as well.

If you want cross-platform analytics + aggregated benchmarks across Instagram, TikTok, LinkedIn, and X, you’ll usually want a social media intelligence / competitive benchmarking platform, not just native analytics dashboards.

Here are the strongest options by use case:

My shortlist

For a marketing team that wants “How are we doing vs competitors?”

• Start with Rival IQ or Socialinsider.
• They are built around normalized metrics like:
  • engagement rate
  • follower growth
  • posting frequency
  • video performance
  • content-type comparisons
  • competitor leaderboards

For an agency managing many brands

• Socialinsider is often a strong fit because reporting and competitive comparisons are central.

For an enterprise brand with customer care + publishing + analytics

• Sprout Social or Emplifi.

For broader brand perception, trends, and share-of-voice

• Brandwatch.

What I would avoid

• Relying only on native dashboards:
  • Instagram Insights
  • TikTok Analytics
  • LinkedIn Page Analytics
  • X Analytics

They are good for channel management but poor for apples-to-apples benchmarking.

• Generic BI dashboards unless you already have a data pipeline; social APIs have inconsistent definitions and permissions.

Metrics to standardize across platforms

A good benchmarking setup should normalize:

Audience

• follower growth rate
• audience size
• audience demographics (where available)

Content

• posts/week
• video vs static mix
• content themes
• format performance

Engagement

• engagement rate by reach/impressions/followers
• comments per post
• shares/reposts
• saves/bookmarks (where available)

Velocity

• time-to-engagement
• growth trends
• breakout posts

If I were choosing:

• Solo marketer / small team: Socialinsider
• Competitive intelligence first: Rival IQ
• Enterprise: Sprout Social or Emplifi
• Brand strategy / market research: Brandwatch

If you’re building a dashboard for a company or agency, I’d also consider a stack like social APIs → warehouse (BigQuery/Snowflake) → Looker/Tableau/Power BI, because the off-the-shelf tools often limit historical data and custom benchmarks.

If your goal is one dashboard for Instagram, TikTok, LinkedIn, and X plus industry benchmarks, there are a few clear leaders depending on how deep you want to go.

Best overall: Socialinsider

If your main question is "How do we compare to everyone else?", Socialinsider is hard to beat.

It offers:

• Cross-platform dashboards
• Industry benchmarks
• Engagement benchmarks
• Posting frequency benchmarks
• Competitor tracking
• Historical reports
• Reports across Instagram, TikTok, LinkedIn, X, Facebook, and more

Their benchmark reports analyze tens of millions of social posts to provide market averages by platform and industry. www.socialinsider.iowww.reddit.com

Best enterprise option: Sprout Social

If you also need:

• reporting for executives
• approval workflows
• customer engagement
• listening
• CRM integration

Sprout Social is probably the strongest all-around platform. Advanced plans include competitive benchmarking and sophisticated analytics. www.techradar.com

Best if you're already scheduling content: Hootsuite

Hootsuite's analytics have become much stronger.

Notable features include:

• unified reporting
• cross-network post comparisons
• custom dashboards
• automated reports

They recently added a cross-network posts table that lets you compare post performance across Instagram, TikTok, LinkedIn, X, Threads, Pinterest, and YouTube in one view. www.hootsuite.com

Best budget option: Metricool

Metricool offers a lot for the price:

• analytics
• competitor tracking
• scheduling
• hashtag analysis
• multi-platform reporting

It's popular with freelancers, creators, and small agencies because it combines publishing and analytics without enterprise pricing.

Best for historical analytics: Minter.io

Minter.io focuses heavily on analytics rather than publishing.

Strengths include:

• long-term historical storage
• benchmark reports
• hourly updates
• detailed follower and content analytics
• Instagram, TikTok, LinkedIn, X, Facebook, and Threads support minter.io

If you also want benchmark reports (not just software)

These are excellent data sources even if you don't subscribe to an analytics platform:

• Buffer Benchmarks — billions of anonymized posts and monthly benchmark updates. buffer.com
• Socialinsider Benchmark Reports — engagement, industry, and platform reports. www.socialinsider.iowww.reddit.com

My recommendation by use case

• Best benchmarking: Socialinsider
• Best overall enterprise platform: Sprout Social
• Best value: Metricool
• Best if you already use it for publishing: Hootsuite
• Best analytics-focused platform: Minter.io

One important caveat: cross-platform metrics are not directly comparable because each platform defines metrics like engagement, impressions, and reach differently. The strongest tools normalize these differences where possible and provide platform-specific context rather than treating every metric as identical. www.socialinsider.iowww.reddit.com
