Backlinks remain one of Google's top three ranking factors. Pages that rank in position one have, on average, 3.8x more backlinks than the pages below them. More than 91% of all indexed pages get zero organic traffic - and 55% of those have no backlinks at all.
So if you want to rank, you need links. The most efficient way to build them is not to start from scratch - it's to look at what's already working for competitors and reverse-engineer it.
This guide covers exactly how to do that: how to track competitor links, how to qualify them, and how to use that intelligence to get the same (or better) links for your own site. Every tactic here is based on publicly available information - no black-hat tools, no guessing.
Why Competitor Backlink Research Works
Your competitors have already done the trial and error. They found publishers, earned editorial placements, got listed in directories, and built relationships with journalists. All of that is logged in their backlink profile - and most of it is publicly accessible with the right tools.
When you analyze a competitor's links, you get a pre-qualified list of sites that:
- Are relevant to your niche
- Are willing to link out to content like yours
- Have already demonstrated they cover topics in your space
- Have a proven track record of linking to commercial or SaaS content
That's a dramatically better starting point than cold outreach to a list you built from scratch.
There's also a compounding effect: if a site links to three of your competitors but not to you, that's a strong signal they'd be open to linking to you too - especially if you can offer better content or a more relevant angle.
Competitor backlink research also helps you identify which content formats attract links in your niche. Are long-form data studies getting cited? Comparison tools? Free calculators? Once you see the patterns, you can build the same type of content and compete for the same links.
Step 1: Identify the Right Competitors to Analyze
Your SEO competitors are not always your business competitors. A company that sells the same product as you might have terrible SEO. Meanwhile, a media site or SaaS blog in your niche might rank above you for every keyword you care about.
The right competitors to analyze are the ones ranking on page one for your target keywords - not the brands you compete with at trade shows.
How to find your actual SEO competitors:
- Search your top 5-10 target keywords in Google and note which domains appear consistently in the top results
- Use Ahrefs or Semrush - go to "Organic Competitors" to see which domains share the most keyword overlap with your site
- Look for sites in similar niches, not just direct product competitors
- Identify 3-5 domains that rank above you, have a similar audience, and cover overlapping topics
Avoid targeting massive brand domains like HubSpot, Salesforce, or Forbes. Their backlink profiles are dominated by brand-recognition links that you can't replicate. Target competitors that are 1-2 tiers above you in domain authority - sites you can realistically match in 12-18 months.
Step 2: Pull Their Full Backlink Profile
Once you have your competitor list, it's time to extract their link data. The main tools for this are:
- Ahrefs - the industry standard for depth and accuracy of backlink data
- Semrush Backlink Analytics - strong for gap analysis workflows
- Moz Link Explorer - good for authority metrics and link intersection
Enter a competitor's domain into the tool. You'll immediately see:
- Total referring domains (unique sites linking to them)
- Total backlinks
- Domain authority/rating distribution across linking sites
- New and lost links over time (trend data)
- Top anchor text patterns
The most important metric is referring domains, not raw backlink count. One site can link to a competitor 200 times (e.g., from every blog post they write), but it still counts as one referring domain. Google weighs unique linking domains far more heavily than repeat links from the same site.
Filter immediately to remove noise:
- Set minimum domain rating (DR) to 40+
- Filter for "dofollow" links only - nofollow links pass no link equity
- Exclude obvious spam domains and link farms
- Exclude internal pages (filter for homepage or top-level pages first)
This narrows a list of thousands down to a manageable set of high-value, actionable targets.
Step 3: Run a Backlink Gap Analysis
Backlink gap analysis shows you domains that link to your competitors but not to you. This is the single most actionable output of any competitor backlink research process.
In Semrush: Use the Backlink Gap tool. Enter your domain and up to four competitor domains. The "Best" tab shows sites that link to all your competitors but not to you.
In Ahrefs: Use the Link Intersect feature. Same concept - enter your domain and competitors, see who links to them but not you.
Sort results by the number of competitors a site links to. If a domain links to four of your competitors, that's a near-certain signal that they're open to linking to content in your niche. They've already voted four times.
Export this list. Filter by DR 40+. This is your initial outreach pipeline.
You'll typically surface 50-200 high-quality link opportunities from this exercise alone, depending on how competitive your niche is. Even if you only convert 10-15% of those into actual links, that's a meaningful boost to your backlink profile in a single outreach cycle.
Step 4: Classify the Backlink Type
Before reaching out to any site, understand how your competitor earned that link. The acquisition method tells you exactly what pitch to run.
Click through to each linking page and look at the context. Is it a guest post? A roundup article? A resource list? A journalist article that cited them as a source?
Common backlink types and what to do for each:
Editorial and Contextual Links
The linking site cited your competitor's content as a source or reference within an article. These are the most valuable links because they're genuinely earned - no link exchange, no payment, just a site deciding your content was worth citing.
How to replicate: Create content that's clearly better than what they cited. Look at the specific page your competitor got cited for. What's outdated? What's missing? What claims are made without supporting data? Build a more comprehensive, data-backed version and pitch it to the same sites as a superior reference. Reference the specific article and explain what your version adds.
Guest Post Links
The competitor wrote content for the linking site and included a link in their author bio or within the body of the article.
How to replicate: Find the contributor guidelines on the linking site. Most sites with guest contributors have a "Write for Us" page. Pitch a topic that fills a content gap they don't already have - not a topic they've covered five times. Review your competitor's published piece to understand what topics the site publishes and what level of depth they expect.
Resource Pages and Curated Directories
The linking site has a curated list of tools, resources, agencies, or businesses in your niche. These pages are built specifically to be linked to, and they're updated regularly.
How to replicate: Reach out with a short pitch that explains what you do and why you fit the list. Keep it to two or three sentences. These sites are predisposed to add relevant entries - they built the list for that reason. The barrier to entry is lower than editorial links, and you can often get added within a week.
Broken Link Opportunities
The competitor's page that earned the link no longer exists - it returns a 404 error. The linking site is currently pointing to a dead page, which hurts their user experience.
How to replicate: This is broken link building, one of the most reliably effective link acquisition tactics. In your SEO tool, go to the competitor's backlink profile, filter for "broken" or "404" pages, and see which broken URLs still have active links pointing to them. Create a page on your site that covers the same topic, then email the linking site to flag the broken link and offer yours as a working replacement. Site owners are motivated to fix broken links - you're doing them a favor.
Podcast and Media Mentions
The competitor was quoted, interviewed, or featured by a journalist, podcast host, or industry publication. These links are hard to get but high-value - and they open doors to repeat coverage.
How to replicate: Identify which journalists and podcast hosts have covered your competitors. Follow them on LinkedIn and X. Engage with their content genuinely for a few weeks before pitching. When you do pitch, offer something they can't get from your competitor: proprietary data, a contrarian take, or a specific case study. Position yourself as a source, not as someone asking for a link.
Step 5: Analyze Their Most-Linked Pages
Beyond the domain-level view, look at which specific pages are attracting the most backlinks. In Ahrefs, this is under "Best by Links." In Semrush, it's under "Indexed Pages" sorted by referring domains.
This tells you which content formats and topics generate links naturally in your niche.
Common patterns to look for:
- Original research and data studies: Any page with original statistics gets cited continuously. Industry benchmark reports, survey results, and market data attract links for years after publication.
- Comparison articles: "Tool A vs Tool B" posts get cited by buyers doing research and by other writers covering the space.
- Comprehensive how-to guides: Deep tutorials become reference points that other content links back to.
- Definition and glossary pages: "What is [term]" pages attract links from educational and media sources who need to define a concept for their readers.
- Free tools and calculators: Interactive tools generate links, bookmarks, and organic traffic simultaneously. If a competitor has a free ROI calculator or audit tool with dozens of links pointing to it, that's a signal worth acting on.
- Infographics and visual content: Visual assets get embedded on other sites, each embedding generating a backlink.
When you identify which of these formats your competitors are successfully using, you have a content roadmap for your next 6-12 months. Build better versions - more current data, more depth, more actionable specifics - and target the same linkers.
Step 6: Set Up Ongoing Competitor Link Monitoring
Competitor backlink research is not a one-time audit. New links appear constantly, and the best opportunities are the ones you catch within days - when the topic is fresh and the linking site is still active on it.
Use Ahrefs Alerts to get email notifications whenever a competitor earns a new backlink. Configure an alert for each of your top competitors. When you see a new link land, you can reach out to the same site immediately while the topic is current.
Also monitor your own brand mentions. Set up Google Alerts or Ahrefs Alerts for your brand name. When someone mentions you but doesn't link to you, that's an unlinked brand mention - one of the easiest link conversions there is. Email the author, thank them for the mention, and ask if they'd be willing to add a link.
Running this continuously turns competitor link tracking from a one-off project into a systematic, ongoing acquisition channel that surfaces new opportunities every week.
For marketing teams managing multiple brands or clients, this kind of continuous monitoring is exactly where automation pays off. Toffu's AI-driven competitor analysis can run these monitoring workflows on autopilot, surfacing new competitor links and flagging high-value opportunities without anyone manually pulling Ahrefs reports each week.
Step 7: Prioritize Your Outreach Pipeline
Not all link opportunities are worth equal effort. Prioritize your outreach by expected ROI.
Tier 1 - Highest priority:
- DR 60+ referring domains
- Sites linking to 3 or more of your competitors (proven niche relevance)
- Resource pages and directories (lowest friction, fastest to convert)
- Broken link opportunities (site owners have an active reason to fix it)
Tier 2 - Medium priority:
- DR 40-60 referring domains
- Editorial links requiring you to create new content first
- Guest post targets (higher effort but strong for anchor text control)
Tier 3 - Lower priority:
- DR under 40 domains
- Forum links and community mentions (usually nofollow)
- Social profile links
Track each target in a spreadsheet: domain, DR, link type, pitch sent, status, response. Keep it simple - five columns is enough. The purpose is to stay organized across what can quickly become a 200-row pipeline.
What to Actually Say in Your Outreach
The research phase is straightforward. The outreach is where most teams fail - not because they're targeting the wrong sites, but because their emails are generic and easy to delete.
What works:
Reference the specific article. Don't say "I found your site and thought you might be interested in my content." Say "I saw your article [Title] - you linked to [Competitor's piece] on [Topic]. I've published an updated version that includes [specific data or section they're missing]."
Be specific about the value. The person receiving your email needs to understand immediately why your link is better than what's there now. Concrete beats vague every time.
Keep it short. Three to four sentences maximum. Editors, journalists, and site owners are busy. A long pitch reads like a template and gets treated like spam.
Follow up once. Wait 5-7 business days after your initial email, then send a single one-line follow-up: "Just checking if you had a chance to see this." After that, move on.
What to avoid:
- Paying for links. Google's manual review team and algorithms have become significantly better at identifying paid link patterns. A link scheme penalty can take months to recover from.
- Mass email blasts. If your outreach software is sending 500 identical emails a day, you'll get a tiny response rate and burn domain reputation.
- Reciprocal link exchanges at scale. One-off swaps occasionally happen, but systematic link exchanges violate Google's guidelines and create detectable patterns.
How Marketing Automation Scales This Process
Running competitor backlink research manually across five competitors takes several hours per month. Multiplied across a team managing multiple clients or brands, it becomes a full-time job.
AI marketing tools can automate the monitoring layer - pulling new competitor links on a schedule, filtering by your criteria, and surfacing only the high-value targets. This is where platforms like Toffu add real leverage. Rather than checking Ahrefs manually each week, you can configure automated competitor monitoring that delivers a curated list of new link opportunities directly to your workflow.
Toffu also supports AI-powered competitor ad and content tracking, which means you can combine backlink monitoring with a broader picture of what competitors are doing across paid and organic - all in one place.
For teams already using scheduled task automation for other marketing workflows, adding competitor link monitoring to that same system creates a genuinely continuous intelligence feed rather than periodic snapshots.
The Full Repeatable Process
Here's the complete workflow you can run monthly:
- Pull backlink profiles for your top 3-5 SEO competitors
- Run a backlink gap analysis to find domains linking to them but not you
- Filter the gap list to DR 40+ dofollow links
- Click through to each linking page and classify the link type
- Check which competitor pages have the most links and identify content gaps
- Build your outreach list, sorted by tier priority
- Write personalized pitches referencing specific articles
- Track outreach in a spreadsheet and follow up once
- Set up automated alerts to monitor new competitor links weekly
Run this cycle monthly and you'll consistently find 20-50 actionable link opportunities per cycle. Even at a 15% conversion rate, that's 3-8 new links per month - compounding over 12 months into a meaningfully stronger backlink profile.
Tracking the Results
After running this process for 2-3 months, you'll want to measure whether the effort is working.
Key metrics to track:
- Referring domain growth: Are you gaining more unique linking domains month over month?
- DR/DA trend: Is your domain authority increasing relative to your competitors?
- Keyword ranking changes: Are pages you've built links to moving up in SERPs?
- Organic traffic: Are ranking improvements translating to traffic growth?
Use Google Search Console to monitor ranking changes for specific pages. Pair it with Ahrefs or Semrush to track referring domain growth.

The Bottom Line
Tracking competitor links is the most efficient shortcut in link building. Your competitors have already proven which sites will link to your niche. Your job is to use that intelligence systematically: classify the link types, identify your highest-value targets, and run outreach that's specific enough to actually get responses.
The teams that do this consistently - not as a one-off project but as a monthly process - see compounding SEO gains over 12-18 months. Start with five competitors, run the gap analysis, and build your first outreach list this week.
