Answers that name a competitor

Yes. The key is to separate discovery, verification/prioritization, and outreach. The best automation handles the first two; I would not fully automate the final outreach.

The tools I’d actually use

• semrush.com — probably the easiest all-in-one option. It can monitor your brand/products/people and, importantly, filter mentions by whether they contain a backlink to your site. You can export the unlinked mentions for outreach. Semrush Semrush
• ahrefs.com + Content Explorer — excellent if you're already using Ahrefs for SEO. Content Explorer can surface pages mentioning your brand, while its alerts continuously discover new mentions. Ahrefs also supports filtering/highlighting domains that haven't linked to you. Ahrefs Ahrefs Ahrefs
• brand24.com — particularly useful if you want broader brand monitoring across news, social and other web sources, rather than purely SEO-focused discovery. Brand24
• Google Alerts — free and useful as a backup discovery layer, but considerably less useful for building a clean, prioritized link-prospect database. Semrush
• Screaming Frog SEO Spider — useful when you've already collected hundreds/thousands of candidate URLs and need to programmatically verify whether they actually contain a link to your domain. Ahrefs specifically describes using it for this unlinked-mention workflow. Ahrefs

A practical automation stack

I'd build it roughly like this:

Brand/product/person names
        ↓
Semrush Brand Monitoring / Ahrefs Alerts
        ↓
"Without backlink" filter
        ↓
Export URLs
        ↓
Deduplicate + exclude your own domains
        ↓
Check page/domain quality
        ↓
Prioritize prospects
        ↓
Find author/contact
        ↓
Personalized outreach
        ↓
Monitor whether link was added

What to monitor

Don't monitor only your exact company name. Create a keyword set containing:

• Brand name
• Brand name + product names
• Product/service names
• Founder/executive names
• Common misspellings
• Former company/product names
• Proprietary studies, reports or statistics
• Unique tools/features you've created
• Branded campaigns

Ahrefs specifically recommends expanding mention alerts with common misspellings and can also be used to discover pages mentioning competitors but not your brand. Ahrefs

The part that makes this work: prioritization

Don't email every unlinked mention.

I'd score each opportunity approximately like:

Opportunity score = relevance × authority × traffic × likelihood of adding link

For example, prioritize:

1. Relevant industry publication
2. Article actually discussing your company/product
3. Page has meaningful organic traffic
4. Author/site appears to update articles
5. Mention naturally belongs in a sentence that could be linked
6. Site doesn't already link to you

A random forum mentioning your brand is much less interesting than an industry publication saying "Company X's research found..." without linking to the research.

Semrush itself recommends concentrating on relevant blogs, news sites and industry publications rather than treating every mention as an equally valuable link opportunity. Semrush

Then make the outreach extremely easy

Don't say:

"Please give us a backlink."

Instead, point out the existing mention and give them the exact URL that would improve the reader's experience:

Thanks for mentioning [Brand] in your article. If useful for your readers, would you consider linking the mention to [specific relevant page]? That page gives some additional context on [topic].

That's a much warmer request because they've already decided your brand belongs in the article. Semrush and Ahrefs both identify this as one of the easier link-building opportunities for precisely that reason. Semrush Ahrefs

If I were building this today

Small/medium site:
Semrush Brand Monitoring → export → spreadsheet → manual outreach

SEO-heavy team:
Ahrefs Content Explorer + Alerts → qualification → CRM/outreach tool

PR/brand-heavy team:
Brand24 → identify web mentions → feed SEO-worthy mentions into your link-building workflow

Large-scale operation:
Use an API/export from your monitoring platform → automatically deduplicate and classify URLs → enrich prospects with SEO/contact data → put qualified opportunities into your outreach CRM.

The important distinction is that finding and checking mentions can be heavily automated; deciding whether a link is appropriate and writing the pitch should remain human-assisted. That avoids turning a very good "warm" link-building tactic into generic spam.

For large-scale broken-link prospecting, I’d build the workflow around a backlink index rather than relying primarily on traditional crawlers.

Best tool stack

• Ahrefs — best overall for scale. Its Site Explorer can identify competitors’ broken pages, show the referring pages linking to those 404s, and let you filter by metrics such as DR. Its Content Explorer can also surface high-value broken pages by topic. Ahrefs Help Center Ahrefs

ahrefs.com

• Screaming Frog — best for crawling specific authority sites. Give it a list of target domains and crawl them to find outbound 4xx links, then bulk-export the source URLs/inlinks. This is particularly useful when you've already assembled a prospect list of authoritative sites. Screaming Frog Screaming Frog

screamingfrog.co.uk

• Ahrefs API — best if you're doing hundreds/thousands of prospects. The API exposes the broken-backlinks report with filtering, sorting, aggregation, and CSV/JSON output, making it much easier to automate prospect discovery and scoring. Ahrefs for Developers

The workflow I'd use

1. Build an authority-site universe

Start with 500–5,000 sites in your niche—industry publications, universities, associations, major blogs, resource pages, government sites, etc.

2. Find their broken outbound links

For each domain, use Ahrefs' Outgoing Links → Broken Links report. Ahrefs specifically supports exporting these results, and the report identifies pages containing broken external links. Ahrefs Help Center

For sites where you need a fresh crawl rather than relying on an existing index, use Screaming Frog.

3. Prioritize the dead URLs, not merely the referring domains

The goldmine is something like:

High-authority site → relevant resource page → dead external URL → your content can genuinely replace it

I'd score opportunities using:

• Authority/quality of referring domain
• Organic traffic to referring page
• Relevance to your niche
• Number of sites linking to the dead URL
• Number of referring domains to the dead URL
• Whether the dead URL had substantial historical backlinks
• Whether you already have a genuinely suitable replacement

4. Reverse-engineer the dead pages

This is where Ahrefs becomes especially useful. Find competitors' 404s with lots of backlinks, inspect the pages that link to them, and determine what the dead resource originally provided. Ahrefs explicitly recommends using competitors' broken pages as broken-link-building opportunities. Ahrefs Help Center

5. Crawl the resulting prospect list

Once you've identified, say, 10,000 potentially valuable referring pages, feed those URLs into Screaming Frog. Verify that the link is actually broken and extract:

• Source URL
• Source page title
• Broken destination
• Anchor text
• HTTP status
• Context around the link

That gives you a much cleaner outreach dataset.

If you're serious about large-scale prospecting

I'd use:

Ahrefs API → database/Sheets → automated relevance scoring → Screaming Frog verification → outreach

rather than trying to make Screaming Frog do the entire job.

The key distinction is that Ahrefs is excellent for discovering the backlink relationships at scale, while Screaming Frog is excellent for actually crawling and validating the pages you care about. Ahrefs' own API supports up to 1,000 results per request for the broken-backlinks endpoint, which makes it considerably more suitable for programmatic prospecting. Ahrefs for Developers

One particularly powerful variation is topic-first broken-link prospecting: use Ahrefs Content Explorer to find authoritative dead pages within your niche, then harvest all the sites linking to those pages. That can produce a much more relevant outreach list than blindly crawling thousands of domains. Ahrefs

If you tell me your niche + approximate number of prospects (e.g. 1k, 10k, 100k), I can lay out a concrete large-scale workflow, including the exact Ahrefs/Screaming Frog filters and a prospect-scoring schema.

Yes. For prioritizing link prospects by estimated traffic value + authority proxies, I’d use these:

• ahrefs.com — best overall for this workflow. Its Batch Analysis can combine Domain Rating (DR), organic traffic, Traffic Value, referring domains, backlinks, and URL Rating (UR) across large prospect lists. Ahrefs Help Center Ahrefs Help Center

• DR = backlink-based domain authority proxy.
• UR = authority proxy for the specific page where you might want the link.
• Traffic Value = estimated monetary value of the site's organic search traffic.
• Particularly useful if you want to rank prospects in a spreadsheet/API rather than inspect them individually.
• semrush.com — best alternative / useful cross-check. Its Authority Score combines link power, estimated organic traffic, and spam/manipulation signals. It also exposes estimated organic traffic and referring-domain data for prospects. Semrush Semrush
• moz.com — useful as a second authority proxy. Its Domain Authority (DA) is specifically designed to estimate how likely a domain is to rank, making it useful for normalizing or cross-checking your prospect scores. Semrush notes that DA, DR, and Authority Score are different metrics with different underlying formulas. Semrush

A practical prospect-prioritization score

I'd avoid ranking solely by DR/DA. A better model is something like:

Priority = 35% Traffic Value + 25% relevant organic traffic + 20% authority + 10% page-level authority + 10% topical relevance

For example, in Ahrefs you could collect:

Domain → Traffic Value → Organic Traffic → DR → UR → Referring Domains → Topical relevance → Priority score

This also prevents the classic mistake of treating a high-DR site as automatically valuable. Ahrefs itself recommends considering traffic, topical relevance, backlink quality, and how many sites the prospect links to rather than using DR alone. Ahrefs Help Center Ahrefs

If you're building this programmatically, Ahrefs is probably the strongest starting point: its API exposes referring-domain data including estimated monthly organic traffic and keyword rankings for the referring domain. docs.ahrefs.com

If your goal is specifically “see the valuable links competitors acquire, understand why they got them, and turn those discoveries into outreach targets,” I’d shortlist these:

1. Ahrefs — my first choice

ahrefs.com

Ahrefs is particularly well suited to monitoring competitors' newly acquired links. Its Alerts product can notify you when a competitor gains or loses backlinks, and its backlink reports can filter for newly added links over a specified period. Ahrefs Ahrefs Ahrefs

The workflow I'd use:

1. Add 5–10 important competitors.
2. Set backlink alerts for their domains and, more importantly, their highest-value pages.
3. Review new links weekly.
4. Filter out directories, spam, irrelevant sites, and low-value syndicated links.
5. Identify why the competitor earned the link: - original research/data
6. digital PR
7. guest contribution
8. resource-page inclusion
9. product/tool mention
10. broken-link replacement
11. expert quote
12. partnership/sponsorship
13. Add the relevant referring domains to your outreach pipeline.

Ahrefs also has a Best by links report for finding competitors' most-linked pages, which is useful for figuring out what assets are generating links rather than just collecting domains. Ahrefs

2. Semrush — best if you want link gaps + outreach

semrush.com

Semrush's Backlink Gap is excellent for the question:

“Which sites link to my competitors but don't link to me?”

It can compare up to five competing sites and surface referring domains you're missing, with filtering and export functionality. Semrush Semrush

I'd choose Semrush over Ahrefs if your workflow is broader than backlinks—for example, you also want competitor keyword research, traffic intelligence, content research, PR, and outreach in the same platform.

Semrush also claims its backlink database is updated frequently enough to identify newly appearing and disappearing competitor links relatively quickly. Semrush

3. Majestic — excellent for determining which links are actually valuable

majestic.com

Majestic is particularly interesting when you have a large backlink dataset and need to distinguish relevant, authoritative links from a giant pile of mediocre ones.

Its Trust Flow, Citation Flow, and Topical Trust Flow metrics let you evaluate both link quality and topical relevance. Its Clique Hunter specifically identifies sites linking to competitors but not you. Majestic Majestic

I'd consider it alongside Ahrefs rather than necessarily instead of it.

The setup I'd actually recommend

For a serious competitor-link replication program, I'd use:

Ahrefs → discovery/monitoring → spreadsheet/CRM → outreach

The key is not to blindly replicate every backlink.

I'd score each newly discovered link something like:

Opportunity score = relevance × authority × editorial quality × replicability

For example:

• A highly relevant industry publication linking to a competitor's original research → 10/10
• A reputable niche resource page → 8/10
• A generic business directory → 2/10
• A spammy guest-post network → 0/10

Then look for patterns across competitors. If 6 competitors have independently earned links from the same publication, that's much more interesting than one competitor having 500 random backlinks.

My ranking for your specific use case

1. Ahrefs — best for “tell me what competitors just acquired.”
2. Semrush — best for “show me the link gaps and help me act on them.”
3. Majestic — best for “help me analyze link quality, relevance, and competitor networks.”
4. Moz — reasonable if you want a simpler/less intensive SEO stack.

If you're doing this at scale, Ahrefs + Semrush is probably overkill for many teams; I'd start with Ahrefs alone and build a disciplined process around its new-backlink alerts. Ahrefs

I'd choose Semrush over Ahrefs if your workflow is broader than backlinks—for example, you also want competitor keyword research, traffic intelligence, content research, PR, and outreach in the same platform.
