Internal Linking for SEO in the Age of AI Overviews
Internal linking gets treated as a solved, boring part of SEO, something to check off with a plugin and forget. That underestimates its role in an environment where AI Overviews and answer engines are increasingly deciding which pages get cited at all.
What Internal Links Actually Do
Internal links serve two separate functions that are easy to conflate. First, they help search engines and AI crawlers discover and understand the relationship between pages, reinforcing which topics your site has genuine depth on. Second, they distribute authority and relevance signals from your strongest pages to pages that need it.
A site with dozens of pages on a topic but no links connecting them looks, to a crawler, like dozens of unrelated pages rather than one comprehensive topic cluster. That distinction matters more now than it used to, because both traditional ranking systems and AI answer engines reward demonstrated topical depth over isolated pages.
Why This Matters More for AI Overviews Specifically
AI Overviews and similar answer engines synthesize responses by pulling from multiple pages, often from the same site, to build a fuller answer. A well-linked cluster of related articles signals a coherent body of expertise a system can draw from confidently. A collection of standalone posts with no connective structure gives an AI system less confidence that any single page represents comprehensive coverage of the topic.
This is the same underlying logic covered in our piece on the Unified Entity Graph: consistency and connection between your own content is itself a signal, not just a user-experience nicety.
How to Structure Internal Links That Actually Help
Anchor text should describe the destination page's actual topic, not generic phrases like "click here" or "learn more." A link with anchor text like "our guide to schema markup" tells both a reader and a crawler exactly what to expect on the other end.
Link from your highest-authority pages down to newer or thinner pages that need reinforcement, not just laterally between pages of similar strength. Your best-performing content is a resource; use it to lift pages that have not yet earned their own authority.
Avoid over-linking. A page with forty internal links spread thin communicates nothing about which relationships actually matter. Three to six genuinely relevant internal links per article, placed where they add real context, do more than a link dropped into every paragraph.
Common Internal Linking Mistakes
| Mistake | Why It Hurts |
|---|---|
| Generic anchor text ("click here") | Gives no topical signal to crawlers or AI systems |
| Orphan pages with zero inbound internal links | Signals the page is not important enough to reference from anywhere else |
| Linking only between pages of similar authority | Wastes the chance to lift weaker pages using stronger ones |
| Excessive links diluting relevance per link | Makes it unclear which relationships actually matter |
A Simple Process for Auditing Your Own Site
Pick your five strongest-performing articles. Confirm each one links to at least two to three related pages with descriptive anchor text. Then check your newest or weakest pages: do any have zero internal links pointing to them from elsewhere on the site? Fixing those two gaps is a practical place to start.
If your structured data is not reinforcing the same topical relationships your internal links describe, see our guide on schema markup and why AI engines need it for the machine-readable half of this same problem. At Schkovl, content architecture like this is part of every Gap Analysis we run.
