GSC Link Reports: How to Audit Your Backlinks for Free

Your Free Backlink Audit Lives Inside Google Search Console

Most site owners spend money on Ahrefs or Semrush to check their backlink profile. What they miss is that Google itself shows you your link data for free - directly inside Google Search Console.

The Links report in GSC isn't as deep as a paid tool. But the data comes straight from Google's index, which means it reflects what actually influences your rankings. Ahrefs shows you links it has crawled. Google shows you links it has counted.

That distinction matters more than most people realize.

Where to Find the Links Report

Log into Google Search Console and select your property. In the left sidebar, scroll down to the Links section. It's near the bottom, below Index and Experience. Click it and you'll see four tables:

• Top linked pages (external) - your pages with the most backlinks
• Top linking sites - domains that link to you most often
• Top linking text - anchor text used in inbound links
• Top linked pages (internal) - your most internally linked pages

Each table shows the top 10 results by default. Click "More" to expand to the full list, and click any row to drill into the detail view.

Reading the Top Linked Pages Report

The external links table shows which pages on your site have attracted the most backlinks. This tells you which content has earned real endorsements from the broader web.

Sort by “Linking sites” rather than “Incoming links” when you want quality signals. A page with 50 links from 50 different domains is generally healthier than one with 200 links from 3 domains.

What you're looking for:

• Your homepage dominates. Normal for most sites. Concern yourself more with which inner pages earn links.
• Old blog posts outrank new product pages. This often reveals a content-link gap. Your best content earns links, but your money pages don't. Fix that with internal linking from those popular posts.
• A page you barely maintain has hundreds of links. That's a traffic and revenue opportunity. Update it, expand it, and make sure it funnels users somewhere useful.
• Critical pages have zero external links. Your pricing page, key landing pages, and pillar content should have at least some external signals. If they don't, link building should be targeted here.

Analyzing Top Linking Sites

This table shows which domains link to your site most frequently. Click any domain to see which of your pages they link to and the anchor text they use.

Run through each major linking domain and ask three questions:

• Is this a site I recognize and respect?
• Does their content make sense linking to mine?
• Are they sending users to a page that actually serves those users?

If a domain you don't recognize appears near the top with dozens of links, investigate it. Open the domain in a browser. Check whether it looks like a real site. A pattern of links from the same low-quality domain repeated many times is a spam signal worth noting.

GSC doesn't tell you about link disavow status - that lives in a separate tool. But identifying suspicious patterns here is the first step before you decide whether to disavow.

Anchor Text: What It Reveals About Your Link Profile

The Top Linking Text table shows the anchor text other sites use when linking to you. A healthy profile looks something like this:

• Brand name variations (your company name, domain, abbreviated forms)
• Navigational text (“click here”, “this article”, “source”)
• Partial match keywords related to your content
• A small percentage of exact-match keywords

Red flags in anchor text distribution include a high percentage of exact-match commercial keywords, particularly if the anchor text matches the keywords you're trying to rank for. This pattern is associated with manipulative link schemes and can trigger manual review.

If your brand name barely appears in the anchor text table and instead you see keyword-rich text dominating, that's worth investigating. Someone may have built links to your site in a way that creates risk rather than benefit.

Internal Links: The Underused Half of the Report

Most people look at the external links section and ignore the internal links table. That's a mistake. The internal links table in GSC shows which pages on your site receive the most links from other pages on your own site.

This matters because internal links pass PageRank between pages. Pages that receive many internal links are effectively being told by your own site structure that they're important. Google notices.

Compare the internal links table with your external links table. The pages getting the most external links should also be getting strong internal link support. If a page earns lots of external links but receives almost no internal links, you're leaving ranking potential on the table.

The reverse is also worth checking. If a page gets heavy internal linking but no external links, ask why the rest of the web hasn't noticed it. Is the content genuinely good? Does it solve a problem someone else would want to reference? If yes, that's a link building target. If not, the internal linking may be inflated relative to the page's actual value.

A proper internal linking strategy starts with this data as the baseline.

Exporting Link Data for Deeper Analysis

GSC's interface shows you patterns but limits detailed analysis. Use the export function to pull raw data into a spreadsheet.

In any expanded view (after clicking “More” on a table), you'll see an export button in the top right. Export to Google Sheets for the simplest workflow.

Once you have the data in a spreadsheet, you can:

• Sort linking domains alphabetically to spot duplicate or similar-looking domains
• Filter for links pointing to specific page paths (like /blog/ or /product/)
• Count unique domains versus total link counts to estimate link diversity
• Cross-reference your top-linked pages against their current organic traffic to see which links are producing results

Combining this with GSC's performance data is particularly powerful. Linking GSC to GA4 lets you see whether your best-linked pages are also your best-converting pages - and whether the correlation holds.

How GSC Link Data Compares to Paid Tools

GSC will show fewer links than Ahrefs, Semrush, or Moz. That's not a bug. Those tools crawl the web independently and index links they discover during crawling. GSC reflects only what Google has chosen to include in its index as a ranking signal.

In practice, this means GSC underreports total link counts but over-represents link quality. A link that appears in GSC's data is a link Google is actively aware of and potentially using. A link that appears only in Ahrefs but not GSC may exist but carry little weight.

For a full link audit, use both. Start with GSC to understand what Google actually counts. Layer in a paid tool to find link opportunities, spot toxic links in bulk, and track link acquisition over time. Link building tactics that work in 2026 depend on understanding this distinction.

If budget is a constraint, GSC alone covers the most important use cases: understanding where your authority is concentrated, spotting obvious spam, and identifying pages that need more link support.

Turning Link Data Into Action

Reading the report is only useful if it changes what you do next. Here's a practical action checklist based on what the data typically reveals:

If your homepage has 90% of external links

You need a content strategy that earns links to inner pages. The homepage is a starting point, not a destination for link building. Target your most valuable product, service, and content pages with specific outreach and content designed to attract editorial links.

If a single domain provides 30% of your links

Your link profile is dangerously concentrated. If that site removes its links or loses authority, your rankings could shift. Diversify by earning links from new domains in different industries and content types.

If a strong page has zero internal links pointing to it

Add internal links from your highest-traffic pages to this underlinked page. Even three or four contextually relevant internal links can meaningfully improve the page's visibility to both crawlers and users.

If your anchor text is dominated by exact-match keywords

Pause aggressive link building and assess whether any recent link campaigns created this pattern. If so, diversifying future anchor text toward brand terms and natural language is the safest path. You can use the backlink analysis tools in MeasureBoard to monitor your anchor distribution over time.

If you spot suspicious linking domains

Document them before taking any action. Google's disavow tool should be used conservatively. If you have a clear pattern of low-quality links from obvious spam sites, compile a disavow file and submit it through Google Search Console. Don't disavow links speculatively.

Monitor Link Changes Over Time

The GSC Links report doesn't show historical trends inside the interface. You can't see that you gained 40 new linking domains last month. But you can track this manually by exporting data on a regular schedule - monthly works for most sites - and comparing snapshots over time.

What to watch month over month:

• Total number of linking sites (growing, flat, or shrinking?)
• New domains that appeared in the top linking sites list
• Pages that gained significant new external links
• Pages that lost links (possible if referring sites went offline or changed their content)

A sudden drop in linking sites is worth investigating quickly. It could reflect link removals, a site-wide penalty affecting sites that link to you, or a crawl issue on Google's side. Cross-reference any link drops against traffic data in GA4's date comparison reports to see if there's a corresponding traffic change.

A sustained, gradual increase in unique linking domains, on the other hand, is one of the healthiest signals a site can show. It means your content keeps earning new endorsements - which is exactly what Google's quality signals are designed to reward.
