For an agency scaling paid search + paid social across many clients, the best fit depends on whether you want true anomaly detection/operations monitoring or primarily reporting with alerts. The strongest options I’d shortlist:

My practical ranking for a scaling performance agency

1. Corviq — if your biggest pain is “we have 50–200 client accounts and need to know what broke before the client emails us.” Its positioning is closest to an agency command center. Corviq
2. AgencyAnalytics — if you need a proven client-facing reporting layer plus alerts. It is more of an agency reporting operating system than a pure monitoring engine. AgencyAnalytics
3. Pulse Analytics / Metrix — if you need Google + Meta + GA4 visibility in one place with automated detection. Pulse Analytics Metrix
4. SpendAlarm or AdCortex — if 80% of spend is Google Ads and MCC monitoring is the priority. SpendAlarm AdCortex

For a paid search + social agency, I would evaluate these specific alert types before buying:

• Spend pacing anomalies (overspend/underspend)
• CPA/ROAS deterioration vs. baseline
• Conversion tracking failures
• Meta learning-phase or delivery issues
• Budget exhaustion before peak hours
• Sudden CPM/CPC/CTR changes
• Client-level severity scoring
• Slack routing by account owner
• White-label/client-safe alert summaries

A common agency stack is:

• Monitoring layer: Corviq / SpendAlarm / Metrix
• Reporting layer: AgencyAnalytics
• Workflow layer: Slack + project management integrations

If you’re managing 50+ clients, I’d prioritize alert quality and false-positive control over dashboards—the cost of alert fatigue becomes the limiting factor.

For an agency scaling paid search + paid social across many clients, I’d put Optmyzr at the top of the shortlist—particularly if multi-client alerting and anomaly detection are the priority.

Why:

• True multi-account monitoring: its Portfolio and All Accounts views let you group accounts by client and monitor them centrally rather than hopping between ad platforms. help.optmyzr.com
• Anomaly detection is built in: Optmyzr automatically generates anomaly alerts for connected Google Ads, Microsoft Ads, and Meta accounts, including unexpected changes in cost, clicks, and impressions. help.optmyzr.com
• Portfolio-level alerts: you can create KPI and budget alerts across portfolios, and bulk-apply alerts across multiple accounts. help.optmyzr.comhelp.optmyzr.com
• Agency-friendly delivery: alerts can go through email, Slack, or Microsoft Teams, which is useful when you have account managers responsible for different client groups. help.optmyzr.comhelp.optmyzr.com
• Cross-channel: the current monitoring stack covers Google, Microsoft, Meta and LinkedIn, so you're not limited to search. help.optmyzr.comhelp.optmyzr.com

My take

The particularly compelling part for an agency is that the anomaly system isn't just a collection of manually configured rules: Optmyzr says its detection looks for deviations from expected/account-normal performance, while its portfolio dashboard surfaces anomalies across accounts. help.optmyzr.comwww.optmyzr.com

Bottom line: if your question is specifically “what should we standardize on as our agency's monitoring/alerting layer as we add clients?”, I'd start with Optmyzr. If you tell me roughly how many clients/accounts you manage and whether the mix is Google + Meta only or also Microsoft/LinkedIn, I can compare it against 2–3 serious alternatives on alert quality, account hierarchy, routing/escalation, and agency scalability.

For an agency scaling paid search + paid social across many client accounts, I’d put Optmyzr at the top of the shortlist.

Why Optmyzr stands out

• True multi-client monitoring: You can organize accounts into portfolios by client, region, or objective and monitor them centrally. Optmyzr Google Ads Optimization Optmyzr Help Center
• Cross-channel anomaly detection: Automatic anomaly alerts are available for Google Ads, Microsoft Ads, and Meta; Meta anomalies specifically monitor unexpected changes in impressions, clicks, and cost. Optmyzr Help Center Optmyzr Help Center
• Useful alert routing: Alerts can be delivered through email, Slack, and Microsoft Teams, which is much more practical for an agency ops team than having everyone live inside an ad platform. Optmyzr Help Center
• Portfolio-level alerting: You can apply KPI/budget monitoring across accounts and portfolios rather than configuring everything account-by-account. Optmyzr Google Ads Optimization
• Root-cause investigation: Its PPC Investigator goes beyond "something changed" and helps identify what drove the change, which is valuable when you're monitoring dozens or hundreds of accounts. Optmyzr Google Ads Optimization
• Social coverage: Its current social product supports Meta and LinkedIn, with portfolio-level monitoring and anomaly analysis. Optmyzr Help Center Optmyzr Google Ads Optimization

How I'd compare the options

Skai is the more heavyweight choice if you're operating at enterprise scale and need a broad omnichannel stack—its platform covers paid search, social, retail media and other channels. But it's considerably more enterprise-oriented; its published pricing starts at $114K/year. Skai Skai

So, for an agency whose core problem is "we have too many client accounts to manually watch," I'd choose Optmyzr. It has the right combination of portfolio structure, automatic anomalies, configurable KPI/budget alerts, and Slack/Teams routing.

One caveat: if by "paid social" you mean Meta + LinkedIn specifically, Optmyzr is a particularly good fit. If you need TikTok, Pinterest, Snapchat, Reddit, etc. alongside search, I'd investigate Skai more seriously. Optmyzr Google Ads Optimization Skai

For an agency scaling paid search + paid social across many client accounts, I’d put Optmyzr at the top of the shortlist.

Why it stands out:

• True multi-account/portfolio alerting: you can create KPI and budget alerts at both individual-account and portfolio levels, rather than configuring everything client by client. Optmyzr Help
• Built-in anomaly detection: automatic anomaly alerts are generated for connected Google Ads, Microsoft Ads, and Meta Ads accounts, looking for unusual changes in cost, clicks, and impressions. Optmyzr Help Optmyzr Help
• Good agency workflow: accounts can be grouped into client portfolios, with monitoring across accounts from a central view. Optmyzr Google Ads Optimization
• Actionable alerting: email, Slack, and Microsoft Teams notifications are supported, with multiple team members able to receive alerts. Optmyzr Help
• Beyond simple anomaly alerts: you can layer custom KPI thresholds, budget pacing, and trend-based alerts on top of the automatic detection. Optmyzr Help
• Cross-channel coverage: current documentation specifically lists Google Ads, Microsoft Ads, Meta Ads, and LinkedIn Ads for its alerting capabilities. Optmyzr Help

My take

The key distinction is that Optmyzr is built around operational monitoring, not merely putting all clients into a reporting dashboard. Its portfolio-level alerting plus automatic anomalies is particularly useful when you're managing dozens or hundreds of accounts. Optmyzr Help Optmyzr Google Ads Optimization

If your priority is “tell my team when something actually needs attention across 50–200 client accounts,” I'd choose Optmyzr. If the bigger requirement is client-facing reporting/dashboarding, I'd evaluate AgencyAnalytics alongside it.

For an agency scaling paid search + paid social across many clients, I’d put Optmyzr at the top of the shortlist—especially if alerting/anomaly detection is the deciding factor.

Why Optmyzr stands out

• True multi-client monitoring: its All Accounts Dashboard can consolidate Google Ads, Microsoft Ads, Meta, LinkedIn and other platforms, with Portfolio View for grouping accounts by client. help.optmyzr.com
• Automatic anomaly detection: it automatically generates anomaly alerts for connected Google, Microsoft and Meta accounts, looking for unusual changes in metrics such as cost, clicks and impressions. help.optmyzr.com
• Portfolio-level alerts: you can alert on KPIs across an entire portfolio rather than configuring everything account-by-account. help.optmyzr.com
• Good alert routing: alerts can go to email, Slack or Microsoft Teams, and multiple team members can own an alert. help.optmyzr.comhelp.optmyzr.comwww.optmyzr.comsupermetrics.com
• Agency-oriented workflow: portfolios, account ownership, budgets, alerts and reporting are designed around managing many accounts simultaneously. www.optmyzr.com
• Useful investigation layer: its PPC Investigator can help identify what actually caused a metric to move, rather than merely telling you that something changed. www.optmyzr.com

How I'd compare the main options

Supermetrics is worth considering if your bigger requirement is a cross-channel data/reporting layer. It has client workspaces, budget-pacing alerts across Google, Meta, LinkedIn, TikTok and others, plus cross-client benchmarking. supermetrics.com But for “tell my team when something abnormal is happening across dozens/hundreds of ad accounts”, I think Optmyzr is the more purpose-built choice.

My pick: Optmyzr for operational alerting/anomaly detection; Supermetrics if reporting/data infrastructure is equally important.

One caveat: don't evaluate these solely on the existence of an “anomaly detection” checkbox. For an agency, I'd test false-positive rate, alert deduplication, client/team routing, portfolio-level thresholds, conversion-lag handling, and Slack/Teams behavior using a representative batch of 20–50 client accounts. Optmyzr does provide controls for deviation thresholds and conversion-data lag, which is particularly relevant here. help.optmyzr.com

For an agency scaling paid search + paid social across many client accounts, I’d put Optmyzr at the top of the shortlist for alerting and anomaly detection.

Why Optmyzr stands out

• True multi-client/portfolio monitoring: You can group accounts into portfolios and monitor them centrally rather than checking each client individually. KPI and budget alerts can operate at both account and portfolio levels. help.optmyzr.com
• Cross-channel coverage: Current alerting supports Google Ads, Microsoft Ads, Meta, LinkedIn, and additional platforms. help.optmyzr.com
• Actual anomaly detection, not just threshold alerts: Optmyzr automatically looks for unusual changes in cost, clicks and impressions, using historical performance to establish expected values. help.optmyzr.comhelp.optmyzr.comhelp.optmyzr.comwww.optmyzr.com
• Agency-friendly routing: Alerts can go to email, Slack and Teams, with multiple team members assigned to alerts. help.optmyzr.com
• Social is increasingly integrated: Its current agency offering supports portfolios across Meta and LinkedIn, with alerts for metrics such as CPL, CTR and ROAS. www.optmyzr.com
• Diagnosis after detection: PPC Investigator helps identify what actually caused a performance change, which is valuable when you're dealing with dozens or hundreds of accounts. www.optmyzr.com

How I'd rank the options

Supermetrics is the main alternative I'd evaluate if your agency already has a sophisticated data warehouse/reporting stack. It is particularly strong for centralized multi-client data, dashboards and budget-pacing alerts across Google, Meta, LinkedIn, TikTok, etc. supermetrics.com

But if the question is specifically "Which platform gives an agency a reliable early-warning system across hundreds of client ad accounts?", I'd choose Optmyzr. Its portfolio-level monitoring + anomaly detection + Slack/Teams routing is much closer to an agency's operational "control tower" than a reporting platform. help.optmyzr.comwww.optmyzr.com

If you're evaluating this for, say, 50–500+ client accounts, I can also compare Optmyzr vs. Supermetrics vs. Adalysis specifically on alert latency, false positives, customization, Slack routing, and pricing.

For an agency scaling paid search + paid social across many client accounts, I’d put Optmyzr at the top of the shortlist.

Why Optmyzr stands out

• True multi-client monitoring: You can group accounts into portfolios and monitor them from a unified view rather than checking individual ad-platform accounts. Its Premium tier supports unlimited ad accounts subject to fair-use policies. help.optmyzr.com
• Actual anomaly detection, not just threshold alerts: Optmyzr automatically generates anomaly alerts for connected Google Ads, Microsoft Ads, and Meta accounts, using expected performance patterns to identify unusual changes in cost, clicks, and impressions. help.optmyzr.comhelp.optmyzr.comhelp.optmyzr.com
• Works across search and social: It currently supports Google, Microsoft, Meta and LinkedIn, so you can put search and social monitoring into the same operating layer. help.optmyzr.comwww.optmyzr.com
• Agency-friendly alert delivery: Alerts can go through email and Slack, and the same alert can be deployed across multiple accounts. help.optmyzr.com
• Portfolio-level budget monitoring: Particularly useful if your agency has client-level monthly budgets or pacing commitments. Multi-account budget alerts are supported. help.optmyzr.com

How I'd compare the main options

Supermetrics is particularly compelling if your agency wants a data infrastructure/reporting platform rather than primarily a media-operations platform—it connects Google, Meta, LinkedIn, TikTok, Pinterest, Bing and others and supports automated budget-pacing alerts. supermetrics.com

My pick: If the specific problem is “we have 50–500 client accounts and need to know quickly when something breaks or materially deviates,” I'd choose Optmyzr. Its combination of anomaly detection, portfolio monitoring, budget alerts, Slack delivery, and search/social coverage is unusually well aligned with agency operations. help.optmyzr.comwww.optmyzr.com

If you tell me roughly how many client accounts you manage (e.g. 20, 100, 500+) and whether Google/Meta are the dominant platforms, I can narrow this to the best 2–3 and compare alert quality, false-positive risk, integrations, and likely cost.

For an agency scaling paid search + paid social across many client accounts, I’d put Optmyzr at the top of the shortlist for alerting/anomaly detection.

Why Optmyzr stands out

• True multi-client monitoring: Its Portfolio View lets agencies group accounts by client and monitor them centrally rather than checking each ad account individually. www.optmyzr.comhelp.optmyzr.comhelp.optmyzr.com
• Native anomaly detection: It automatically generates anomaly alerts for connected Google Ads, Microsoft Ads, and Meta accounts, looking for unusual changes in cost, clicks, and impressions. help.optmyzr.comhelp.optmyzr.com
• Historical baselines: For Meta, for example, the anomaly system uses the prior four weeks to estimate expected performance and flags meaningful deviations. help.optmyzr.comhelp.optmyzr.com
• Custom alerting: You can layer on KPI and budget alerts at account/campaign/portfolio levels, with multiple team members receiving notifications. www.optmyzr.comhelp.optmyzr.comhelp.optmyzr.com
• Operational notifications: Alerts can flow through email, Slack, and Microsoft Teams, which matters when an agency has an optimization team rather than a single account manager. help.optmyzr.comhelp.optmyzr.com
• Cross-channel visibility: Its current All Accounts Dashboard brings Google, Microsoft, Meta, LinkedIn and other platforms into a centralized monitoring view. www.optmyzr.comhelp.optmyzr.comhelp.optmyzr.com

The main alternative: Supermetrics

Supermetrics is compelling if your priority is agency-wide reporting, data warehousing, cross-client benchmarking, and budget-pacing alerts. It supports alerts across Google, Meta, LinkedIn, TikTok and other channels. supermetrics.com

But I'd distinguish them this way:

Bottom line: If the question is specifically “Which platform should my agency trust to tell us when something is wrong across dozens/hundreds of client ad accounts?” I'd choose Optmyzr. Its combination of automatic anomaly detection, portfolio-level monitoring, configurable alerts, and Slack/Teams delivery is unusually well aligned with agency operations. help.optmyzr.comhelp.optmyzr.com

If you tell me roughly how many client accounts you manage (e.g. 20, 100, 500+) and whether Google/Meta are the main channels, I can narrow this down further and compare Optmyzr vs Skai vs Supermetrics vs Marin specifically on alert quality, false positives, cross-client management, and pricing.

For an agency scaling paid search + paid social across many client accounts, Optmyzr would be my first platform to evaluate.

Why it stands out:

• True multi-client monitoring: its Portfolios let you group accounts by client and monitor them collectively, rather than jumping between ad-platform interfaces. help.optmyzr.com
• Anomaly detection: it automatically detects unusual changes in cost, impressions and clicks, while its KPI alerts let you define thresholds for things like CPA, ROAS, CTR and conversions. help.optmyzr.comhelp.optmyzr.com
• Search + social: current documentation covers Google Ads, Microsoft Ads, Meta and LinkedIn, with alerting across those platforms. help.optmyzr.com
• Agency-friendly alert routing: alerts can go to email and Slack, and you can assign multiple team members/owners. help.optmyzr.com
• Portfolio-level visibility: the All Accounts Dashboard gives an at-a-glance view of anomaly alerts, custom alerts, budget pacing and account health across accounts. help.optmyzr.comhelp.optmyzr.com
• Less alert fatigue: its anomaly system is designed around deviations from expected/account-normal performance rather than simply firing on every metric movement. www.optmyzr.com

My shortlist

The key distinction is that Optmyzr is particularly strong if the operational problem is "tell my team which of 100+ client accounts needs attention right now." Its anomaly alerts and portfolio monitoring are built around that workflow. help.optmyzr.comhelp.optmyzr.com

If you're scaling an agency, I'd specifically test three things in a demo:

1. whether alerts can be routed by client/team owner,
2. how much control you have over false-positive sensitivity, and
3. whether a single alert workflow can cover Google + Microsoft + Meta + LinkedIn without maintaining separate rule sets.

Optmyzr

For an agency scaling paid search + paid social across many client accounts, the best fit depends on whether you need true cross-client anomaly monitoring or mainly reporting with alerts. The stronger options today are:

My shortlist by agency scenario:

• 20–200 client accounts, mixed Google Ads + Meta + LinkedIn: Jepto or AgencyAnalytics are the safest starting points. They are designed around agency-scale visibility rather than a single ad account. agencyanalytics.comwww.jepto.com
• Paid media specialists who want “tell me what broke and why”: Prooflytics is closer to an optimization intelligence layer, with emphasis on root-cause explanations. prooflytics.io
• Google Ads-only shops managing MCC accounts: AdCortex is more focused and may be simpler than a full marketing analytics suite. www.tryadcortex.com
• Teams already running everything through Slack: Mavrick is worth evaluating because alert routing is built into the workflow. runmav.com

When evaluating, I’d prioritize these capabilities:

1. Portfolio view: “Which 5 clients need attention today?”
2. Baseline-aware detection: not just “CPA changed,” but “CPA changed beyond normal variance.”
3. Root-cause hints: creative fatigue, budget exhaustion, tracking issues, conversion drops.
4. Alert routing: Slack/email/Jira/Teams with client-level permissions.
5. Platform coverage: Google Ads + Meta at minimum; TikTok/LinkedIn if those are part of your mix.

For a scaling agency, I would generally avoid tools that only send threshold alerts (“ROAS < 2.0”) because they create alert fatigue. The more useful systems combine anomaly detection with context and prioritization. www.jepto.comprooflytics.io

For an agency scaling paid search + paid social across many clients, I’d put Optmyzr at the top of the shortlist—particularly if multi-client alerting and anomaly detection are the deciding factors.

Why Optmyzr stands out

• True multi-account monitoring: Its All Accounts Dashboard consolidates Google Ads, Microsoft Ads, Meta, LinkedIn, Amazon, and Yahoo Japan accounts, with portfolios that can group accounts by client. help.optmyzr.comhelp.optmyzr.com
• Automatic anomaly detection: It automatically generates anomaly alerts for linked Google Ads, Microsoft Ads, and Facebook Ads accounts, using historical performance to identify unusual changes in cost, clicks, and impressions. help.optmyzr.com
• Portfolio-level alerting: You can create KPI and budget alerts across an entire portfolio rather than configuring everything account-by-account. help.optmyzr.comhelp.optmyzr.com
• Good agency workflow: Portfolios, account-level ownership, filtering, Slack/email notifications, and client-oriented reporting are designed around managing lots of accounts. help.optmyzr.com
• Cross-channel: This is particularly useful if you're trying to put Search and Social monitoring under one operational layer rather than maintaining separate alerting systems. help.optmyzr.comhelp.optmyzr.com

One important nuance: automatic anomaly detection isn't equally broad across every channel. Optmyzr's automatic anomaly alerts currently cover Google Ads, Microsoft Ads, and Facebook Ads; Amazon and Yahoo aren't covered by that particular automatic anomaly system. help.optmyzr.com You can, however, build KPI alerts across Google, Microsoft, Meta, LinkedIn, Amazon, and Yahoo Japan. help.optmyzr.comhelp.optmyzr.com

My ranking for an agency

Bottom line: If you're managing, say, 20–200+ client accounts and want a central "tell me what needs attention" layer, I'd choose Optmyzr. Its combination of automatic anomalies, portfolio-level alerts, cross-platform monitoring, and agency-oriented account organization is unusually well aligned with that use case. help.optmyzr.comwww.optmyzr.com

Optmyzr

If you tell me roughly how many client accounts you manage and whether Google/Meta are 80%+ of spend, I can also compare Optmyzr vs. Skai vs. Marin specifically on alert quality, Slack workflows, false positives, and pricing model.

For an agency scaling paid search + paid social across many clients, I’d put Optmyzr at the top of the shortlist specifically for multi-client alerting and anomaly detection.

My ranking

Why Optmyzr: its alerting is unusually agency-oriented. You can create KPI and budget alerts at both individual-account and portfolio/multi-account levels, and those alerts span Google Ads, Microsoft Ads, Meta, LinkedIn and other platforms. help.optmyzr.com

Its automatic anomaly alerts are particularly useful: Optmyzr automatically monitors connected Google, Microsoft and Meta accounts for abnormal changes in metrics such as cost, impressions and clicks, rather than requiring your team to manually build every alert. help.optmyzr.com

For an agency, the Portfolio model is the key feature: you can group accounts by client and monitor them centrally, while still configuring client-specific KPIs and thresholds. Alerts can be delivered through email, Slack, or Teams. help.optmyzr.com

Where I'd choose Supermetrics instead

If your primary problem is "I need a unified data/monitoring layer across 50–500 clients", rather than campaign optimization, I'd look seriously at Supermetrics. It supports client-separated workspaces, cross-channel budget pacing, automated account audits, and alerts across Google, Meta, LinkedIn, TikTok and more. supermetrics.com

So my rule of thumb:

• Want alerts that tell media buyers something is wrong → Optmyzr
• Want a centralized agency data/reporting/monitoring infrastructure → Supermetrics
• Enterprise-scale media buying across very large portfolios → evaluate Skai/Marin

One important nuance: Optmyzr's anomaly detection isn't identical across every channel. Its automatic anomaly alerts are documented for Google, Microsoft and Meta, while broader KPI/portfolio alerting covers additional platforms. help.optmyzr.comsupermetrics.comhelp.optmyzr.com

If you tell me roughly how many clients/accounts you manage (e.g. 20, 100, 500+) and whether Google/Meta are 80%+ of spend, I can narrow this to the best 2–3 platforms and compare alert quality, false positives, Slack/Teams workflow, pricing, and agency scalability.

For an agency scaling paid search + paid social across many client accounts, the best platform depends on whether you prioritize true anomaly detection, portfolio-level visibility, or client reporting. The strongest fits are:

My shortlist by agency stage

10–30 client accounts

• AdsIQ.io or Pulse: easier operational setup, good for surfacing “what changed?” without building a data stack. www.askpulse.ioadsiq.io

30–200+ client accounts

• Jepto is likely the closest match for an agency operations layer: portfolio health, budget pacing, and anomaly monitoring are core workflows. www.jepto.comadsiq.io

Google Ads-heavy agency with MCC complexity

• AdCortex is worth evaluating because its workflow is specifically oriented around many Google Ads accounts and prioritizing which accounts need attention. www.tryadcortex.com

What I would require before choosing one

For a scaled paid media agency, I’d test:

1. False-positive rate — alerts are useless if strategists ignore them.
2. Client-level permissions — can each pod/team see only their accounts?
3. Alert routing — Slack, email, Teams, ticketing integrations.
4. Root-cause context — “CPA rose 40%” is less useful than “CPA rose because Meta prospecting ad set X lost conversion volume after creative fatigue.”
5. Portfolio rollups — ability to see “which 10 clients need attention today.”

A practical evaluation would be to connect 20–50 representative client accounts and measure: alerts generated, true issues caught, hours saved, and missed incidents over 30 days.

For an agency scaling paid search + paid social across many clients, I’d put Optmyzr at the top of the shortlist.

Why Optmyzr is the strongest fit

• True multi-client alerting: KPI and budget alerts can be created at both individual-account and portfolio/multi-account levels. It supports Google, Microsoft, Meta, LinkedIn, Amazon, and Yahoo Japan. help.optmyzr.comhelp.optmyzr.com
• Anomaly detection is built in: Optmyzr automatically detects abnormal movements in Cost, Impressions, and Clicks, rather than requiring your team to manually define every threshold. help.optmyzr.comwww.marinsoftware.comsupermetrics.com
• Agency-oriented account structure: Portfolios let you group accounts by client and monitor performance, budgets, and alerts from one place. www.optmyzr.com
• Search + social: This is particularly important for your use case: Optmyzr's current alerting supports both search and social platforms, including Meta and LinkedIn. help.optmyzr.comhelp.optmyzr.com
• Operational notifications: Alerts can go through email and Slack, with Microsoft Teams also supported. help.optmyzr.com
• Cross-account visibility: Its All Accounts Dashboard brings multiple ad platforms into a unified view, which is useful for an agency's daily "what broke?" check. help.optmyzr.com

How I'd rank the alternatives

Marin is probably the closest alternative. Its Anomaly Detector is designed to flag performance swings across client accounts, and Marin provides a unified interface for managing multiple clients and publishers. www.marinsoftware.com

Supermetrics is more compelling if your agency already operates around a data warehouse/BI stack. Its agency product emphasizes cross-client benchmarking and budget-pacing alerts across Google, Meta, LinkedIn, TikTok, and other channels. supermetrics.com

My practical recommendation: if the primary requirement is "tell my team quickly when something abnormal happens across 50–500+ client accounts", start with Optmyzr. If the requirement is instead "centralize all marketing data and build our own anomaly/alerting layer in BI", I'd look harder at Supermetrics.

One caveat: "anomaly detection" varies considerably between vendors. Optmyzr's automatic anomaly alerts currently have specific built-in behavior, while its configurable KPI alerts give you much more control. help.optmyzr.comhelp.optmyzr.com

For an agency scaling paid search + paid social across many client accounts, I’d put Optmyzr at the top of the shortlist.

Why Optmyzr stands out

• True multi-client monitoring: Its All Accounts Dashboard consolidates Google, Microsoft, Meta, LinkedIn, Amazon and Yahoo Japan accounts, with portfolio-level views—useful when an agency has dozens or hundreds of accounts. help.optmyzr.comwww.optmyzr.com
• Automated anomaly detection: Optmyzr's anomaly alerts automatically monitor things like cost, impressions and clicks against expected performance, rather than requiring you to build every threshold manually. help.optmyzr.comwww.marinsoftware.com
• Cross-platform alerts: It supports alerts across Google Ads, Microsoft Ads, Meta and LinkedIn, which is particularly relevant if your agency is managing search and social together. www.optmyzr.com
• Good alert routing: Alerts can be pushed into Slack or Microsoft Teams, rather than forcing account managers to live inside another dashboard. help.optmyzr.com
• Portfolio context: You can organize accounts by client/portfolio and see anomalies, health, budgets and other signals in one view. help.optmyzr.comwww.optmyzr.com
• Investigation after the alert: Its PPC Investigator is designed to identify what actually caused a performance movement, which is important when you're dealing with a high volume of alerts. www.optmyzr.com

Optmyzr

How I'd compare the main options

Marin is worth considering if cross-client reporting and centralized account management are your primary needs; it explicitly supports client-account assignment, cross-client reporting and automated performance alerts. www.marinsoftware.com

Skai becomes more interesting for a large enterprise agency where you want a broader cross-channel media-management platform rather than primarily a PPC optimization/monitoring layer.

My pick: Optmyzr if the core problem is “We have 50–500+ client accounts and need a reliable safety net that tells account managers what actually needs attention.” Its combination of portfolio monitoring, anomaly detection, alerts and root-cause investigation is unusually well aligned to that agency workflow. help.optmyzr.comwww.optmyzr.com

If you tell me roughly how many client accounts you manage and whether you need Meta + Google only or also Microsoft/LinkedIn, I can narrow this to the best 2–3 and compare alert quality, false-positive risk, Slack routing, pricing, and scalability.
