How to Analyze Competitor Backlinks and Steal Their Best Link Sources

Your competitor is ranking above you for every keyword that matters. You have better content, a faster site, and more on-page optimization than they do. But they have one thing you do not: a backlink profile that tells Google they are the authority in your space. The gap is not content quality. It is link equity, and closing that gap requires understanding exactly where their links come from and how to get links from the same sources.

Competitor backlink analysis is the most efficient link building strategy because it eliminates the guesswork. Instead of cold-emailing random websites hoping for a link, you are targeting sites that have already demonstrated willingness to link to content in your niche. These sites linked to your competitor. They are predisposed to link to similar content. You just need to give them a reason to link to yours instead.

This guide covers the complete process: identifying the right competitors to analyze, extracting and filtering their backlink data, categorizing link sources by type and opportunity, building outreach campaigns that convert, and scaling the process so it becomes a repeatable engine rather than a one-time project.

Why Competitor Backlink Analysis Beats Cold Outreach

Traditional link building starts with a target keyword, creates content around it, and then cold-emails hundreds of websites hoping someone will link to it. The response rate on cold link building outreach is typically 1-3%. Most emails are ignored. Many are marked as spam. The process is slow, demoralizing, and produces inconsistent results.

Competitor backlink analysis flips this model. Instead of guessing which sites might link to you, you start with sites that have already linked to similar content. These sites have demonstrated three things: they cover your topic area, they are willing to link externally, and they have editorial processes that allow outbound links. Every one of those qualifications makes them significantly more likely to link to you than a random outreach target.

The response rates reflect this advantage. Outreach to sites identified through competitor backlink analysis typically converts at 5-12%, three to four times higher than cold outreach. The reason is simple: you are not asking a stranger for a favor. You are offering a relevant resource to someone who has already shown interest in your topic.

Step 1: Identify the Right Competitors to Analyze

The competitors you analyze for backlinks are not necessarily the same competitors you track for business intelligence. You want to analyze sites that rank for your target keywords, regardless of whether they are direct business competitors. A blog, a media publication, or an educational resource that ranks for your keywords has a backlink profile that is directly relevant to your SEO goals, even if they do not compete with you commercially.

Finding Your SEO Competitors

Start with your top 10-15 target keywords. Search each one in Google and record which domains appear in the top 5 results. The domains that appear repeatedly across multiple keywords are your primary SEO competitors. They are the ones you need to analyze because they have built the link profiles that Google rewards for your topic area.

Use Ahrefs' "Competing Domains" report or SEMrush's "Organic Competitors" to automate this process. These tools identify sites that share the most keyword overlap with yours and rank them by the degree of competition. Choose 3-5 competitors for your initial analysis. Going beyond five creates too much data to process effectively and dilutes your focus.

Include at least one competitor that is slightly above your level (10-20% more organic traffic) and one that is significantly above (3-5x more organic traffic). The first shows you achievable near-term opportunities. The second shows you where the ceiling is and what kind of link building produces category-leading results.

Step 2: Extract and Filter Backlink Data

Once you have identified your competitors, the next step is extracting their backlink data and filtering it to focus on actionable opportunities. Raw backlink exports from Ahrefs or SEMrush contain thousands or tens of thousands of links, most of which are irrelevant for outreach. The filtering process is where the real analytical work happens.

Exporting Backlink Data

In Ahrefs, enter each competitor's domain in Site Explorer and navigate to the "Backlinks" report. Export the full report with the following columns: referring page URL, referring domain, domain rating (DR), anchor text, target URL, link type (dofollow/nofollow), and first seen date. Repeat for each competitor and combine the exports into a single working spreadsheet or database.

In SEMrush, use the Backlink Analytics tool with similar export settings. The terminology differs slightly (Authority Score instead of Domain Rating) but the data structure is equivalent. If you have access to both tools, cross-referencing their data can reveal links that one tool detected and the other missed.

The Filtering Process

Apply these filters sequentially to narrow the raw data to actionable opportunities.

Filter 1: Domain Rating threshold. Remove all linking domains with a DR below 20. Links from very low-authority sites provide minimal SEO value and are often spam, PBNs, or auto-generated directories. For most campaigns, a DR 30+ threshold is even better, but DR 20 ensures you do not miss smaller legitimate sites.

Filter 2: Relevance. Remove linking domains that are clearly outside your topic area. A link from a recipe blog to a SaaS competitor is likely a coincidence or a guest post on an off-topic site. These links may help the competitor's domain authority but they are not replicable in a meaningful way. Focus on sites that cover your industry, your technology category, or your buyer persona's professional interests.

Filter 3: Link type. Separate dofollow links from nofollow links. Dofollow links pass ranking authority and are your primary targets. Nofollow links from high-authority sites (like major publications) still have value for brand visibility and referral traffic, but they should be a secondary priority for SEO-focused link building.

Filter 4: Active pages. Remove links from pages that return 404 errors or have been de-indexed. These links no longer pass value to the competitor and cannot be replicated. Check a sample of pages using a bulk URL checker to estimate the percentage of dead links in your dataset.

Step 3: The Link Intersection Analysis

The most powerful technique in competitor backlink analysis is the link intersection: finding sites that link to multiple competitors but not to you. These sites are the highest-probability outreach targets because they have demonstrated a pattern of linking to content in your space. They are not just willing to link externally. They are actively curating resources in your topic area.

Running the Intersection

Ahrefs' Link Intersect tool does this automatically. Enter your domain in the "But doesn't link to" field and your competitors' domains in the "Show me who links to" fields. The tool returns a list of domains that link to your competitors but not to you, sorted by the number of competitors they link to.

A domain that links to all five of your competitors but not to you is a near-certain outreach target. They are clearly interested in your topic and have linked to similar content multiple times. The question is not whether they would consider linking to you, but whether you have content worth linking to.

Prioritize the intersection results by the number of competitors linked to. Sites linking to 4-5 competitors are your top tier. Sites linking to 2-3 are your second tier. Sites linking to only one competitor are your third tier, as they may have a specific relationship with that competitor rather than a general interest in the topic.

Step 4: Categorize Link Sources by Type

Not all backlinks are acquired the same way, and understanding how a competitor earned a link determines how you can replicate it. Categorize each link source into one of the following types, as each requires a different outreach approach.

Editorial Links

These are links placed by editors or authors because the linked content is genuinely useful or informative. They appear within article body text, typically with descriptive anchor text. Editorial links are the highest-value type because they signal genuine endorsement. To replicate them, you need content that is clearly better than what the competitor offers. This is the "skyscraper" approach: identify the content that earned the link, create something more comprehensive or more current, and reach out to the linking site with your improved version.

Resource Page Links

Many websites maintain curated resource pages that list useful tools, guides, or references for their audience. These pages are link-building goldmines because the explicit purpose of the page is to link to external resources. If a competitor is listed on a resource page, requesting inclusion is straightforward. Your outreach explains that you noticed their resource page, that your content covers a related topic, and that it might be a valuable addition for their audience.

Find resource pages by searching for "your topic" + "resources" or "useful links" or "recommended tools" in Google. Cross-reference the results with your competitor backlink data to identify resource pages that already link to competitors.

Guest Post Links

If a competitor earned a link through a guest post, the site accepts contributed content. These are replicable by pitching your own guest post. Examine the guest post to understand the site's content standards, topic preferences, and audience. Then pitch a complementary topic that provides value to their readers while naturally linking back to your site.

Identify guest posts by looking for author bios that mention the competitor's company, or by checking if the author is listed as a contributor rather than staff. Sites with guest post programs typically have a "write for us" or "contribute" page that outlines their submission guidelines.

Mention Links

These are links within articles that mention the competitor as an example, a data source, or a tool recommendation. The article is not about the competitor but references them in context. To replicate mention links, you need to understand why the competitor was mentioned. If they were cited as a data source, you need original data or research. If they were mentioned as a tool, you need product visibility in the author's awareness.

Directory and Listing Links

These come from software directories (G2, Capterra, Product Hunt), business directories, and industry-specific listings. They are the easiest to replicate because most directories accept self-submissions. While individually they carry less weight than editorial links, they build a foundation of domain-relevant links and referral traffic. Check which directories your competitors are listed in and ensure you are listed in the same ones.

Step 5: Identify Link-Worthy Content Patterns

Before building outreach campaigns, analyze which types of content earn the most links from your competitors. This analysis reveals the content formats and topics that attract links in your niche, which should inform your content strategy.

The Content-Link Matrix

For each competitor, group their backlinks by the target URL. Identify the pages that attract the most unique referring domains. These are the competitor's "link magnets." Analyze what makes them link-worthy. Common patterns include: original research with unique data, comprehensive guides that serve as definitive references, free tools or calculators, industry benchmark reports, and visual assets like infographics or data visualizations.

If you notice that competitors' research reports attract 5x more backlinks than their how-to guides, that signals that your niche values original data over instructional content. If their free tools attract the most links, investing in interactive content may be more efficient than writing more articles. Let the data guide your content investment decisions.

The Skyscraper Analysis

For each of the competitor's top link-earning pages, assess whether you can create something meaningfully better. "Better" means more comprehensive, more current, better designed, or containing original data that the competitor's version lacks. If you cannot genuinely improve on the competitor's content, do not pursue a skyscraper approach for that particular page. Focus on the opportunities where you can create a clearly superior resource.

Document the specific improvements you would make for each skyscraper opportunity. "Our version will be longer" is not a sufficient improvement. "Our version will include original survey data from 500 marketers, interactive calculators for each metric, and quarterly updates" is a genuine value proposition that justifies outreach.

Step 6: Build the Outreach Campaign

With your targets identified, categorized, and prioritized, it is time to build outreach campaigns. The key principle is that outreach templates should be customized by link category, not generic. An email to a resource page curator is fundamentally different from an email to a journalist who mentioned your competitor in an article.

Outreach Template: Resource Pages

For resource page targets, your email should acknowledge the resource page, explain why your content fits, and provide a specific suggestion for where it could be added. Keep it concise. The resource page curator is busy and does not need your company's backstory. They need to know what you are offering and why it is relevant to their audience.

The subject line should reference their specific page: "Suggestion for your [topic] resources page." The body should be three sentences: acknowledge the page ("I've been using your [topic] resources page and noticed you link to several guides on [subtopic]"), introduce your resource ("We recently published [title], which covers [specific angle not represented]"), and make the ask ("Would you consider adding it to the page?"). Include the URL. Do not ask them to visit your site and find it themselves.

Outreach Template: Skyscraper / Editorial

For editorial link targets where you have created a superior version of competitor content, the approach is more nuanced. You are essentially asking someone to update an existing article with a better link. This requires tact. Do not mention the competitor by name or frame it as a competitive play. Focus entirely on the value your content provides to the linking site's audience.

Reference the specific article where the link appears. Explain that you noticed they linked to a resource on [topic]. Share that you have created an updated version that includes [specific improvements]. Ask if they would consider linking to your version as well, or as a replacement if the original is outdated. Always position it as adding value for their readers, not as doing you a favor.

Outreach Template: Guest Posts

For sites that accept guest posts, pitch a specific topic with an outline. Generic "I'd love to write for your site" pitches get deleted. Specific "Here is a 1,500-word article on [topic] that complements your recent piece on [related topic]" pitches get responses. Include 2-3 headlines with brief descriptions, reference a specific article on their site that your piece would complement, and briefly establish your expertise.

Follow-Up Cadence

Most link building outreach that converts does so on the follow-up, not the initial email. Send a maximum of two follow-ups: one at 5-7 days and one at 12-14 days. Keep follow-ups shorter than the original email. Simply reference the original email and ask if they had a chance to review it. After two follow-ups with no response, move on. Three unanswered emails is the professional limit.

Step 7: Scale with a Repeatable Process

Competitor backlink analysis is not a one-time project. Your competitors acquire new links every week, which means new opportunities appear continuously. Building a repeatable process turns this from a project into an engine.

Monthly Monitoring

Set up Ahrefs alerts for each competitor's domain to receive notifications when they acquire new backlinks. Review these alerts weekly and add promising sources to your outreach pipeline. New links are especially valuable outreach targets because the linking site is actively publishing and linking, which means they are more likely to respond to outreach.

Once a month, run a fresh link intersection analysis to identify new domains that have started linking to multiple competitors. These new intersection domains represent emerging authorities in your space that are building their own resource collections, making them receptive to link suggestions.

The Outreach Pipeline

Manage your outreach in a CRM or spreadsheet with these fields: target domain, target URL (the page where you want the link), contact name, contact email, outreach date, follow-up dates, link category, content asset being pitched, status (sent/follow-up 1/follow-up 2/won/lost/no response), and acquired link URL. This tracking enables you to measure conversion rates by category, identify which content assets earn the most links, and optimize your templates over time.

Content Investment Decisions

Use your competitor backlink analysis to inform content strategy decisions. If your analysis reveals that original research reports earn 5x the links of how-to content in your niche, invest accordingly. If interactive tools and calculators are the biggest link magnets, allocate development resources to building them. Let the backlink data tell you what the market values, and build more of that.

Advanced Techniques for Competitive Link Intelligence

Broken Link Building from Competitor Profiles

Competitors lose pages over time through redesigns, URL changes, and content deprecation. When a competitor page disappears, every site that linked to it now has a broken link. These broken links are outreach opportunities. Contact the linking site, inform them of the broken link, and suggest your content as a replacement. This approach has a higher conversion rate than standard outreach because you are solving a problem for the webmaster, not just asking for a favor.

Use Ahrefs' "Broken Backlinks" report on competitor domains to find pages that have been removed but still have inbound links. Sort by the number of referring domains to find the biggest opportunities. Create content that covers the same topic as the defunct competitor page, then reach out to every site that linked to it.

Anchor Text Analysis for Keyword Strategy

Analyzing the anchor text distribution of competitor backlinks reveals which keywords they are actively building authority for. If a competitor has an unusually high concentration of exact-match anchor text for a specific keyword, they are likely running an active link building campaign for that term. This tells you where they see their biggest SEO opportunity and where you should expect increasing competition.

Conversely, if a competitor has strong rankings for a keyword but few backlinks with that anchor text, they are ranking primarily on content quality and domain authority. These keywords may be easier to compete for because the competitor's position is not reinforced by targeted link building.

New Competitor Detection

Monitor which new domains start acquiring links from your known link sources. If a new site begins appearing in backlinks from sites that typically link to companies in your space, it may be an emerging competitor or a new content player worth watching. Early detection of new competitors gives you time to analyze their strategy before they become a serious ranking threat.

Common Mistakes in Competitor Backlink Analysis

Chasing quantity over quality. A competitor with 10,000 backlinks from low-quality sites is not necessarily harder to outrank than one with 500 links from authoritative, relevant domains. Focus your analysis and outreach on high-quality links that actually move rankings, not on matching a competitor's total link count.

Ignoring link context. A backlink from a relevant paragraph in a related article is worth more than a link from a footer, sidebar, or author bio. When categorizing links, note where the link appears on the page. This context affects both the SEO value and the difficulty of replication.

Trying to replicate unreplicable links. Some competitor links come from unique circumstances: the founder is friends with a journalist, the company sponsored a conference, or the link was placed during an acquisition. These links are not replicable through standard outreach. Identify them and filter them out so you do not waste outreach effort on impossible targets.

Neglecting content quality. No amount of outreach sophistication compensates for mediocre content. If you are pitching content that is merely adequate, your conversion rate will be low regardless of how well-targeted your outreach is. The content you pitch must genuinely deserve the link. If it does not, improve the content before launching outreach.

Not tracking and learning. Every outreach campaign generates data about what works and what does not. Which templates get responses? Which content assets earn the most links? Which link categories convert best? If you are not tracking these metrics and optimizing based on results, you are repeating the same mistakes in every campaign.

Your competitors have already done the hard work of discovering which sites will link to content in your space. Competitor backlink analysis lets you leverage that work by targeting proven link sources instead of guessing. The process is systematic, repeatable, and produces measurably better results than any other link building approach. Start with a link intersection analysis of your top three SEO competitors, identify the gaps, build superior content to fill them, and begin outreach. Within 90 days, you will have closed a measurable portion of the backlink gap that separates you from the sites outranking you today.
