Backlink Analysis: How to Audit Links Step by Step

Updated September 19, 2026· 8 min read

What is backlink analysis?

Backlink analysis is a structured review of links from other websites to your site. It identifies where each link appears, which page it reaches, how it is described, whether it still works, and what action the evidence supports.

A useful audit ends with a decision list. It separates links to protect, links to reclaim, destination pages to improve, credible outreach opportunities, and patterns that need manual review.

Backlink tools use different indexes, so their totals will not match. Treat every export as one view of the link profile rather than a complete list of links across the web.

What should a backlink analysis deliver?

A backlink audit should answer five practical questions:

1. Which pages and resources earn relevant editorial links?
2. Which valuable links are broken, redirected, or no longer present?
3. Does the anchor text and placement look natural in context?
4. Which competing resources earn links that your page does not?
5. What should the team protect, reclaim, improve, investigate, or pursue next?

The output is more useful than a single authority score. A score can help sort a large export, but it cannot replace reading the referring page and checking the destination.

How do you run a backlink analysis?

1. Export link data. Start with Google Search Console for the verified property. Add a third-party index when you need competitor data, historical discovery, or wider coverage.
2. Normalize and deduplicate the exports. Standardize domains and URLs, remove duplicate source-to-target pairs, and retain source-specific first-seen and last-seen dates.
3. Group links by referring domain and target page. Find destination pages that attract links and domains that link more than once.
4. Review page-level quality. Read the source page and inspect relevance, editorial context, placement, link attributes, anchor text, accessibility, and destination fit.
5. Check link status. Confirm whether the link is live, removed, redirected, broken, or still unverified. Follow redirects to the final canonical destination.
6. Review anchor patterns. Separate brand names, URLs, topical phrases, and commercial phrases. Investigate unusual repetition instead of assuming it is harmful.
7. Compare relevant competing pages. Find credible sources that link to competing resources but not to yours, then identify what those resources provide.
8. Assign a next action. Route each finding to protection, reclamation, destination improvement, outreach, manual review, or no action.

Pair the findings with a documented link-building strategy so the audit leads to specific work.

Backlink audit worksheet

Use one row for each source-page and target-page pair. Keep the original export fields so another reviewer can trace every decision.

Field	What to record	Why it matters
Referring page	Full source URL	Lets a reviewer inspect the actual context
Referring domain	Normalized root domain	Supports grouping and deduplication
Target page	Final canonical destination	Finds broken URLs, redirect chains, and concentrated links
Anchor text	Visible linked words or linked-image alt text	Shows context and unusual commercial patterns
Placement	Main copy, resource list, author bio, directory, footer, or sitewide template	Separates editorial references from repeated templates
Link attribute	Standard, nofollow, sponsored, or ugc when observable	Prevents treating every link as equivalent
First and last seen	Dates supplied by the source	Helps investigate new or possibly lost links without claiming certainty
Relevance note	Relationship between the source topic and destination	Forces page-level review instead of score-only triage
Status	Live, redirected, broken, removed, or unverified	Routes reclamation work
Next action	Protect, reclaim, improve, outreach, review, or no action	Converts analysis into accountable work

Worked hypothetical example

Assume an industry association’s resource page links to an old research report on your site. The link sits in the main article, uses the report title as anchor text, and now passes through two redirects before reaching a general service page.

Field	Example finding
Referring page	Industry association resource guide
Target page	Retired research-report URL
Placement and anchor	Editorial resource list using the report title
Status	Live link with a two-hop redirect to a weak substitute
Relevance	Strong topic match and clear editorial reason for the citation
Next action	Restore an equivalent report or redirect directly to the closest useful replacement, then ask the publisher to update the URL

The example does not need a proprietary score to support a decision. The referring context is relevant, the original citation had a clear purpose, and the current destination no longer satisfies that purpose.

What signals show backlink quality?

Backlink quality depends on the relationship between the source page, the link, and the destination. Review observable evidence before using a vendor metric as a filter.

Signal	Questions to ask
Topical relevance	Does the source page cover a subject related to the destination?
Editorial context	Does the link support the surrounding sentence or resource list?
Placement	Is the link in useful main content, an author bio, a directory, a footer, or a sitewide template?
Referring page	Does the page load and contain substantive publisher-controlled content?
Anchor text	Does the wording describe the destination without a repeated pattern of commercial keywords?
Link attribute	Is the link standard, nofollow, sponsored, or ugc?
Link status	Is it live, redirected, broken, removed, or still unverified?
Destination	Does the final page load, match the reference, and avoid an unnecessary redirect chain?

Use the evidence to route work:

• Protect or reclaim first: a relevant editorial link points to a useful destination that is broken or unnecessarily redirected.
• Improve the destination: credible sources link to stronger competing resources because your page lacks the cited material.
• Review manually: the pattern includes commercial anchor concentration, unclear ownership, suspicious placement, or a possible policy issue.
• Take no action: the link has little value but creates no manual-action concern.

Which tools can you use for backlink analysis?

Choose tools based on the question, not one headline total. Product access, limits, and interfaces can change, so confirm them in current official documentation before starting an audit.

Tool	What it contributes	Best use	Access and limits to verify
Google Search Console	A first-party sample of top linking sites, top linked pages, and linking text for a verified property	Reviewing your own site	Individual report tables show up to 1,000 rows; the landing-page external-link export can provide up to 100,000 rows. Links may be historical, and the report does not show nofollow status
Ahrefs	A separate backlink index with link history and competitor comparisons	Broader discovery and competitor gaps	Confirm plan access, export limits, index scope, and proprietary metric definitions
Semrush	Backlink research alongside keyword, competitor, and site-audit tools	A combined SEO research workflow	Confirm project, export, competitor, and historical-data limits
Moz Link Explorer	Inbound-link, anchor-text, and proprietary authority reporting	Link prospecting and campaign review	Confirm query, export, tracking, and index limits

Search Console’s Links report is not a complete backlink index. Individual report tables are limited to 1,000 rows, while the landing-page external-link export can provide up to 100,000 rows. The report is also separate from the Search Analytics API used for search clicks and impressions. Export link rows from the Links report when you need to review the verified property’s backlink sample.

Teams can combine exports when a decision requires more coverage, then track the work in an analytics dashboard.

How do you run a backlink gap analysis?

A backlink gap identifies credible pages that link to competing resources but not to yours. The goal is to learn why those sources linked, then decide whether your destination or outreach deserves improvement.

1. Choose two to four pages that compete for the same topic. Avoid comparing whole domains with different audiences.
2. Export referring pages and domains from a third-party index. Search Console only reports the verified property.
3. Find relevant sources that link to more than one competing resource but not to your page.
4. Read each source page and record what its current citations provide.
5. Compare that editorial need with your page. Identify a missing dataset, example, tool, template, definition, or point of view.
6. Improve the destination when needed, then write an outreach note tied to the exact source page and reader need.
7. Track discovered prospects, outreach, responses, and earned links as separate stages.

How should you prioritize backlink opportunities?

Start with assets and relationships that already show a credible editorial reason to link.

1. Reclaim relevant links that now point to a broken page or poor replacement.
2. Protect pages that already earn useful citations and keep their referenced material current.
3. Improve destinations when competitors earn links through a resource your page lacks.
4. Pursue backlink gaps where the source, audience, and editorial need clearly match.
5. Review suspicious patterns only when the evidence supports investigation.

Original research, useful templates, calculators, and complete reference guides give publishers a concrete reason to cite a page. A generic outreach list does not fix a destination that offers nothing distinct.

When should you use Google’s disavow tool?

Use Google’s disavow tool only when many spammy, artificial, or low-quality links caused, or are likely to cause, a manual action. Most sites should not use disavowal as routine cleanup or submit every suspicious-looking domain.

Google states that both conditions should apply:

1. A considerable number of spammy, artificial, or low-quality links point to the site.
2. Those links caused a manual action or are likely to cause one.

Review Google’s official disavow guidance before submitting a file. If a manual action involves unnatural links, document attempts to remove links and avoid disavowing organic links.

What can backlink data prove?

Backlink data can show relationships, link patterns, status changes recorded by a provider, and opportunities for closer review. It cannot prove that a link caused a ranking change, that one index found every link, or that a vendor score represents Google’s evaluation.

For wider context, a 2023 Ahrefs study reported that 96.55% of roughly 14 billion pages in its Content Explorer index had zero estimated organic traffic from Google. This is a third-party traffic estimate, not evidence that any one backlink caused or prevented traffic.

How Anderson Collaborative uses backlink analysis

Backlink analysis is strongest when it explains why a page earned attention. We group links by destination, context, and likely editorial motive, then use that pattern to improve link-worthy assets rather than chase isolated domain scores.

Frequently Asked Questions

What is backlink analysis?

Backlink analysis is the process of reviewing links from other websites to your site. The review shows which pages attract links, where links come from, how anchor text is used, and which opportunities or risks need investigation.

How do you analyze backlinks?

Export link data, combine and deduplicate the sources, then review referring pages, linked pages, relevance, placement, link attributes, and anchor text. Compare relevant competitors and turn the findings into a prioritized action list.

Which tools can you use for backlink analysis?

Google Search Console provides a sample of links to a verified property. Ahrefs, Semrush, and Moz maintain separate third-party indexes with competitor research and proprietary metrics. Use more than one source when coverage matters.

Should you disavow spammy backlinks?

Google says to disavow only when a considerable number of spammy, artificial, or low-quality links caused or are likely to cause a manual action. Most sites should not treat disavowal as routine cleanup.
