How do internal links truly impact the crawling and ranking of your pages?

Why does Google emphasize site structure?

Google crawls billions of pages every day. To prioritize and understand what it discovers, it heavily relies on structural signals. Internal links create a graph that Googlebot navigates: the more qualified internal links a page receives, the more important it is considered within your ecosystem.

But there is more. Internal links provide semantic context. If ten pages on your site point to a product page with the anchor "waterproof trail shoes," Google understands that this page discusses trail running and waterproofing, not just generic shoes. This contextual signal enhances thematic understanding and can guide positioning on niche queries.

What is the difference between a clear anchor and a vague anchor?

A clear anchor describes the content of the target page in a concise and precise way. "Click here," "learn more," or "this page" are vague anchors that provide no value to Google. They dilute the semantic signal and deprive you of a free optimization lever.

Mueller recommends using the product name or a brief description. In practice, this means: if you are linking to a product page for "Sony WH-1000XM5," the ideal anchor is "Sony WH-1000XM5" or "Sony WH-1000XM5 noise-canceling headphones," not "discover this headset." This precision helps Google match your page to relevant queries.

Does this statement change anything for an already optimized site?

Not really if you are already applying the fundamentals of internal linking. This reminder from Mueller confirms what SEO practitioners have observed for years: descriptive anchors improve performance of target pages. However, many sites still neglect this lever, particularly on blogs where generic anchors like "read the article" are prevalent.

For an e-commerce site with thousands of products, this rule implies reviewing the templates for automatic anchors. If your "similar products" blocks display "View product" everywhere, you are wasting potential. Replacing it with the exact product name costs zero dollars and can unlock positions on long-tail keywords.

• Internal links structure the crawl and guide Googlebot to your priority pages
• Descriptive anchors enhance the semantic understanding of the target page by the algorithm
• Vague anchors ("click here," "learn more") dilute the signal and provide no SEO value
• This rule particularly applies to e-commerce sites and blogs with large content catalogs
• An internal linking audit should prioritize anchor quality as much as link quantity

Does this statement align with real-world observations?

Absolutely. A/B tests on internal linking consistently show that context-rich anchors improve the ranking of target pages, especially on long-tail queries. One case observed: a B2B site replaced its "view solution" anchors with anchors that precisely described each service. In three months, organic traffic to these pages rose by 22% with no other changes.

However, Mueller remains vague on one critical point: what is the optimal anchor density? Should you vary the formulations or repeat the exact same anchor everywhere? Google does not specify. Real-world experience suggests a mix: one main exact anchor repeated on 60-70% of links, with semantic variations for the rest. But this is an interpretation, not a certainty. [To be verified]

What nuances should be added to this rule?

The first pitfall: do not confuse clarity with over-optimization. An anchor like "buy cheap running shoes with free shipping" is clear but spammy. Google penalizes anchors loaded with commercial keywords. The line is blurry, but one empirical rule is: if your anchor resembles a Google query, it’s probably too much.

The second nuance: structure is as important as anchors. You can have perfect anchors but a site with excessive click depth (pages more than 5 clicks from the homepage) that hampers crawling. A complete SEO audit must therefore combine anchor analysis AND structure analysis. Both are inseparable.

In what cases is this rule not enough?

On a new or low-authority site, optimizing internal links does not compensate for a backlink deficit. Google needs external signals to trust your internal structure. If no one is linking to your site, your internal linking remains a secondary optimization. Focus on link building first.

Another limitation is sites with duplicate content or thin content. If your target pages lack editorial value, perfect anchors won't make a difference. Google may crawl your site better and understand your structure more clearly, but it won’t rank empty pages. Content always takes precedence.

What concrete steps should be taken on an existing site?

Start an internal linking audit using Screaming Frog or Oncrawl. Export all internal link anchors and filter those containing "click here," "learn more," "read more," "see," "discover." These generic anchors are your top rewriting priorities. On a typical site, they often represent 30 to 50% of the total linking.

For each vague anchor, replace it with the exact name of the target page or a description of 3-6 words maximum. If the target page is "Complete Guide to Local SEO," the anchor becomes "local SEO guide," not "this guide." Automate where possible (product templates, categories), but manually revise strategic pages.

How can you check that the new structure is crawled correctly?

Monitor the Search Console section "Crawl Stats." After modifying the linking, you should observe a slight increase in the number of pages crawled per day, especially for pages that previously received few internal links. If nothing changes after 4-6 weeks, the issue lies elsewhere (robots.txt, loading time, saturated crawl budget).

Also use server logs if you have access. Compare the crawl frequency of pages before and after anchor optimization. Pages that now receive internal links with descriptive anchors should be crawled more often. If this is not the case, check that they are not mistakenly blocked by a noindex or pointing to another URL with a canonical tag.

What errors should absolutely be avoided in this optimization?

Do not create an artificial linking scheme just to place anchors. Internal links should remain editorially coherent. If you add ten links to a product page from unrelated articles, Google may detect the manipulation and ignore these signals. The context of the source page is as important as the anchor itself.

Another common error is using exactly the same anchor everywhere. This looks spammy. Slightly vary the formulations while keeping the main keywords. For example: "Sony noise-canceling headphones," "Sony WH-1000XM5 noise-canceling headphones," "WH-1000XM5 Sony headphones" are three different anchors but semantically close. Google understands natural variation.

• Audit all internal link anchors and identify vague anchors ("click here," "see," "learn more")
• Replace with descriptive anchors including the name or a brief description of the target page (3-6 words max)
• Ensure strategic pages receive enough internal links from relevant pages
• Automate anchors in templates (products, categories) but manually review key pages
• Monitor the crawl evolution in Search Console and server logs after deployment
• Avoid over-optimized anchors (too many commercial keywords) and slightly vary formulations
