We Audited 187 Small-Business Websites. Half Have Pages Nothing Links To.

The big internal-linking studies are impressive — 23 million links here, 2.5 million there — and almost useless to a small business, because they're built from SEO-tool customer bases: content sites, e-commerce catalogs, enterprises with thousands of pages. The web most businesses actually live on — the 20-page plumber, the 60-page clinic, the 150-page manufacturer — is missing from the data.

So we measured it. Our free audit tool, Crawlmouse, has been grading real websites since June. This report aggregates what it found across 187 distinct small-business-scale websites — and the picture is worse, and more fixable, than the big studies suggest.

Finding 1 — Half of all sites have pages nothing links to

50.3% of the 187 sites have at least one orphan page — a page that exists, may even rank, but that no other page on the site links to. Search engines struggle to find orphans; AI crawlers, which follow links rather than guessing URLs, mostly never see them.

And the intensity is the real story: on affected sites, the median share of orphaned pages is 20.1%. Not one forgotten page — one in five. That's service pages, location pages, old-but-ranking blog posts, sitting disconnected from the structure that's supposed to carry them.

For contrast, the widely-cited figure from large-site studies is that roughly a quarter of pages lack internal links. Our site-level view of the small web says the problem is not an enterprise disease. It's everywhere, at every size.

Finding 2 — 3 in 4 sites over-optimize their anchor text

75.4% of sites (141 of 187) triggered over-optimized-anchor findings — the same link text repeated again and again pointing at the same page, usually a keyword phrase, usually the legacy of an old SEO playbook. Modern search systems read that pattern as manipulation, and at minimum it wastes the descriptive signal internal links are supposed to carry.

Full disclosure, because it's both honest and useful: our own website scored a B- on Crawlmouse's internal-linking grade during its build, partly on this exact finding — our early cross-links repeated identical anchors. We varied them, added a build gate that fails when two inbound links to the same page share anchor text, and published the whole episode. The point isn't that we're above the statistic. It's that the statistic is so easy to join and so mechanical to fix.

Finding 3 — The smallest sites have the weakest structure

You'd expect a 20-page site to be easy to structure well. The data says otherwise:

The tiniest sites — the largest group in our corpus — score worst, by a wide margin. The likely reason: very small sites are built once, from a template, and never get a deliberate linking pass; there's no "SEO person" and no process. Mid-size sites (26–100 pages) do best — big enough that someone thought about structure, small enough that it's still manageable by hand.

The practical read for a small business: your structural problems are probably worse than the big company's you're competing with — and fixable in an afternoon, because you have 25 pages, not 25,000.

Finding 4 — The grade curve: the median website is a C+

Median score: 69.6 of 100. Only one site in fourteen earns an A. Which means the bar for beating your local competitors' site structure is genuinely low — most of the market is a C.

Finding 5 — WordPress beats custom builds (yes, really)

The dig at WordPress from custom-build shops — we run a custom stack ourselves — isn't supported by this data. WordPress's conventions (menus, categories, related posts) impose a baseline structure that many custom builds never replicate. A custom site is only as linked as someone deliberately made it. Templates have opinions; blank pages don't.

Two more numbers worth knowing

21.9% of sites bury content more than three clicks deep — despite a corpus median of just 58 pages. Depth is a choice, not a size problem. And 14.4% of sites triggered JavaScript-rendering flags — pages whose content risks being invisible to the AI crawlers that, per Vercel's published crawler analysis, do not execute JavaScript. (Crawlmouse began scoring full AI-readiness mid-corpus, so that deeper dataset — 41 sites so far — is held for a future edition rather than published at a weak n. When it's big enough, it gets its own report.)

What to do with this, in one paragraph

Run the free audit on your own site — crawlmouse.com, one minute, no signup. If you're in the orphaned half, connect the disconnected pages; if you're in the 75% with cloned anchors, vary them so each link describes its destination. These are afternoon fixes with compounding returns, and the grade tells you exactly where you stand against the 187 sites above. If you'd rather have it done — with the before/after measured on the same tool — that's work we do, priced openly.
