Backlinks

Backlinks are incoming links from external domains pointing to your site. In practice, they matter because they help Google assess authority, discover pages, and compare competing documents when on-page relevance is already close.

That part is not controversial. Google has said links remain important for ranking for years, and Google's John Mueller has repeatedly clarified that links are still a factor, just not the only one. The mistake is treating every backlink as equal. They are not. A contextual link from a relevant DR 70 page can move a query. Fifty sitewide footer links usually will not.

What actually matters

• Referring domains over raw link counts: In Ahrefs and Semrush, 200 links from 3 domains is a weak profile. Fifty links from 50 relevant domains is usually stronger.
• Relevance: A cybersecurity company getting links from B2B SaaS, developer publications, and enterprise IT sites makes sense. Coupon sites and random directories do not.
• Placement: Links inside the main body content pass more value than author bios, sidebars, or footers. Screaming Frog can help audit internal placement patterns; Ahrefs shows the external source pages.
• Indexation and crawlability: A link on a page blocked by robots.txt, canonicalized away, or not indexed is a bad bet. Check source URLs in Google Search Console and by direct inspection.
• Anchor text: Exact-match anchors still work, but overuse is how teams create a pattern Google can discount. For most brands, keeping commercial exact-match anchors under 10% is a sensible ceiling.

How SEO teams measure backlinks

Use Google Search Console for Google's own sample of linking sites. Use Ahrefs or Semrush for broader link discovery, lost link monitoring, and competitor gap analysis. Moz is still fine for high-level authority comparisons, though most link teams lean on Ahrefs for freshness. Surfer SEO is not a backlink tool, but it can help you judge whether links are the missing variable versus content depth.

A practical benchmark: if the top 5 ranking pages average 150 referring domains and your page has 18, you probably do not have a content problem. You have a link equity problem.

Where backlink advice goes wrong

The industry still oversells DR, DA, and toxicity scores. Those are third-party metrics, not Google metrics. They are useful for prioritization, not truth. A DR 35 niche site with real traffic and editorial standards can beat a DR 80 site built on syndicated junk.

Another caveat: not every page needs backlinks. Category pages, linkable assets, and commercial landing pages often do. Routine blog posts usually do not. Also, disavow is not routine maintenance. Google is good at ignoring a lot of spammy noise. Unless you have a manual action or a clear pattern of manipulative links, mass disavows are usually wasted effort.

Bottom line: backlinks still matter, but quality, relevance, and page-level context matter more than vanity metrics and bulk link counts.
