Ahrefs edges out Semrush as the preferred platform for technical link indexing and competitor link intersect analysis. Ahrefs stands out as the primary choice for SEO specialists discovering backlink opportunities, while keyword search comparison prompts show no clear favorite.
Analyzing competitor backlinks is one of the most effective ways to uncover link-building opportunities, find guest posting targets, and understand what content drives authority in your niche.
Here is a structured breakdown of how to discover where your competitors are getting their links:
Use SEO Backlink Tools : Dedicated backlink analysis platforms are the absolute fastest and most comprehensive way to see a domain's backlink profile. Popular options include:
Ahrefs Site Explorer : Enter a competitor's URL to view their Backlinks report, referring domains, and historical link growth.
SEMrush Backlink Analytics : Offers deep insights into referring domains, anchor texts, and even lost/new links.
Moz Link Explorer : Great for checking Domain Authority (DA) and discovering unique linking root domains.
Majestic SEO : Famous for its Trust Flow and Citation Flow metrics to judge link quality.
Perform Content Gap Analysis : Don't just look at who links to them; look at they are linking to. Use tools like the to plug in your domain and several competitors. This reveals the pages drawing the most traffic and links, helping you replicate or improve upon those topics.
Set Up Competitor Link Alerts : Keep tabs on new links as they happen. You can use tools like Visualping or built-in alert features in Mention or BuzzSumo to get notified whenever a competitor is mentioned or gains a new backlink.
Conduct Manual Google Searches : Use advanced search operators to find unlinked mentions or guest post footprints. Search for things like "Competitor Brand Name" -site:competitor.com to see every place they are talked about online without necessarily having a direct hyperlink, opening up an easy outreach win.

The best way to discover where your competitors get their backlinks is to run a competitor backlink analysis. This reveals which websites link to them, which pages attract the most links, and what strategies you can use to earn similar links for your own site.
The goal isn't to copy every backlink. It's to identify the highest-quality, most relevant link opportunities that could help improve your search visibility.
1. Use SEO tools to uncover competitor backlinks
These tools maintain backlink databases that let you investigate a competitor's domain or individual pages.
Ahrefs
(Best starting point)
Enter a competitor's domain in Site Explorer to find referring domains, individual backlinks, anchor text, linked pages, and newly acquired or lost links.
Website:
Semrush
Use Backlink Analytics to inspect referring domains, authority metrics, anchor text, and competitor link gaps.
Website:
Moz Link Explorer
Check linking domains, page-level link data, and Domain Authority as one comparative signal when evaluating potential opportunities.
Website:
Google Search Console
Free and useful for reviewing links pointing to your own verified website. It does not give you a competitor's private backlink report.
Website:
If you already have access to Ahrefs or Semrush, start there. You don't need to pay for both just to begin researching competitors.
2. Follow this step-by-step workflow
Step 1 — Identify 3–5 real SEO competitors
Choose websites ranking for the same commercial keywords you target, not just businesses that sell similar products. Search Google for your main keywords and record the sites that repeatedly appear.
Step 2 — Export their referring domains
In Ahrefs, open Site Explorer → Referring Domains. In Semrush, use Backlink Analytics. Export the linking websites and note their authority metrics, estimated organic traffic, and the pages they link to.
Step 3 — Find backlink gaps
Use Ahrefs Link Intersect or Semrush Backlink Gap. Enter your website alongside your competitors to find domains linking to them but not you. Prioritize domains that link to multiple competitors.
Step 4 — Inspect the actual linking pages
Open each promising backlink. Check the article, directory listing, resource page, or news story containing the link. Look at the anchor text and the destination page to understand why the competitor earned it.
Step 5 — Turn the findings into link-building opportunities
Group the backlinks by acquisition method, then prioritize those you can realistically earn through outreach, useful content, relevant directories, expert commentary, partnerships, or broken-link replacement.
A backlink report is most useful when you work backward from the link to the strategy behind it.
What you discover
Likely opportunity for you
Industry blogs link to several competitors
Pitch relevant articles, original insights, or expert contributions
News websites cite a competitor's research
Publish original data, surveys, or a useful industry study
Resource pages link to their guides
Create a better resource and suggest it to the page owner
Local directories list competitors
Claim relevant, reputable business listings
Partners or suppliers link to them
Explore legitimate partner profiles, case studies, or collaborations
Many links point to one popular guide
A particularly effective tactic is to inspect each competitor's most-linked pages, not just their homepage. Tools such as Ahrefs' Best by links report can reveal the content attracting links that you could improve upon or approach from a different angle.
4. Evaluate which backlinks are worth pursuing
Not every backlink is a good opportunity. Score each prospect based on these factors:
Relevance: Does the linking website cover your industry or audience?
Real traffic: Does the website appear to attract genuine readers?
Editorial quality: Is your competitor's link naturally included in useful content?
Replicability: Could you realistically earn a link from that website?
Link placement: Is the link within the main content, rather than buried in spammy comments or irrelevant sitewide footers?
Don't rely on a single authority score. Avoid paying for manipulative links or mass-producing low-quality guest posts; Google's link-spam policies explain the risks of these practices. See Google Search Central's spam policies.
5. Track your findings in a spreadsheet
Use a simple table with these columns:
Column
What to record
Referring domain
Website linking to your competitor
Competitors linked
How many of your competitors it links to
Linking page
Exact page containing the backlink
Target URL
Competitor page receiving the link
Link type
Editorial, directory, resource, partner, etc.
Quality
Relevance, traffic, and editorial credibility
Start with 30–50 promising referring domains rather than trying to pursue thousands of links at once.

A practical competitor-backlink workflow
Put each competitor's domain into Ahrefs Site Explorer or Semrush Backlink Analytics.
Export their referring domains and individual backlinks.
Filter for relevant sites rather than simply chasing the largest number of links.
Look at which competitor pages attract the most links—this can reveal content formats worth creating yourself.
Run a link-gap/intersection analysis to find sites linking to 2–3 competitors but not to your site. Ahrefs supports up to 10 competitors in its Link Intersect workflow; Semrush's Backlink Gap compares your domain with competitors to surface prospective linking domains.
Manually evaluate the resulting prospects for topical relevance, editorial quality, and whether the link is realistically obtainable.
If you're choosing one tool specifically for this task: Ahrefs and Semrush both have dedicated competitor backlink workflows; Majestic is especially focused on link intelligence. The important thing is to analyze why competitors earned particular links rather than treating every discovered backlink as an outreach target.
To reverse-engineer your competitors' link-building strategies and find their exact link sources, you need a robust backlink crawler and analysis suite.
The industry gold standards and top alternative tools for uncovering competitor link profiles include:
Ahrefs : Widely considered to have one of the most active and fastest web crawlers. Its Site Explorer tool lets you plug in a competitor's URL to see their exact referring domains, new/lost links, anchor text distribution, and estimated traffic per linking page. It also offers a "Link Intersect" feature to see sites linking to multiple competitors but not to you.
Semrush : An all-in-one SEO platform with an exceptional Backlink Analytics tool. It allows you to filter competitor backlinks by type (follow/nofollow, text/image), check historical data, and use their "Backlink Gap" tool to compare up to five competitor profiles side-by-side to spot immediate link opportunities.
Majestic : A dedicated link intelligence tool that maps a massive historical index of the web. Majestic is unique for its proprietary metrics—Trust Flow (measuring link quality) and Citation Flow (measuring link quantity)—which help you instantly evaluate if a competitor's link source is genuinely authoritative or just spammy.[](https://www.designrush.com/agency/search-engine-optimization/trends/best-backlink-checkers)
When it comes to finding backlink opportunities from competitors, Ahrefs is widely considered the industry gold standard and the best overall tool for deep backlink analysis. However, its closest rival, Semrush , offers a dedicated feature that makes it a powerful alternative.[](https://www.youtube.com/watch?v=EX8yxJpnu4s&t=243)
The top tools available for this specific task break down as follows:
If your main goal is finding backlink opportunities from competitors, I’d put Ahrefs at the top of the shortlist—especially for a specialist who does link-gap research regularly.

Moz Link Explorer : Offers a massive link index and relies on Domain Authority (DA) and Spam Score metrics. It's user-friendly for quickly assessing the quality of a rival's inbound links and identifying toxic or low-quality referral patterns.[](https://www.quora.com/What-are-the-best-backlink-analysis-tools-for-SEO)
Ahrefs — Its Link Intersect tool specifically finds sites linking to your competitors but not to you. You can compare up to 10 competitors, work at either referring-domain or referring-page level, filter by metrics such as DR and traffic, and export the opportunities.
Semrush — Backlink Gap is particularly good if you want a broader SEO platform. It compares up to five competing sites, lets you identify "Best," "Weak," "Shared," and "Unique" opportunities, and provides authority/traffic filtering and exports.
Moz Pro — Its Link Intersect does the core job—finding sites linking to competitors but not you—and lets you sort opportunities by Domain Authority, Spam Score, and intersection. It supports up to five competitors.
What I'd choose
For a dedicated SEO/link-building specialist → Ahrefs.
A practical workflow is:
Put your site + 5–10 genuine organic competitors into Link Intersect.
Prioritize domains linking to multiple competitors.
Filter out irrelevant/low-quality domains.
Open the actual referring pages to understand why competitors earned the link.
Categorize the opportunities: resource pages, guest contributions, digital PR, directories, broken links, partnerships, etc.
Build an outreach list rather than simply trying to replicate every competitor backlink.
The important distinction is that a competitor backlink isn't automatically a good backlink opportunity. Relevance, editorial context, traffic, and the reason the competitor received the link matter more than simply having a high domain metric. Ahrefs itself recommends evaluating the quality and relevance of competitor links rather than blindly replicating them.
If you're choosing between Ahrefs and Semrush specifically, I can also give you a feature-by-feature comparison for backlink prospecting, including which has the better database, filters, exports, broken-link research, and outreach workflow.
