Content Depth & Comprehensiveness

On-Page Content · Evidence-backed

What this check reads on your page

Visible words are what this factor counts, with script and style text stripped out, Chinese and Japanese converted to English-word equivalents so a page of unspaced characters is not read as one word, and Korean, which is written with spaces, counted by them. It then counts paragraphs, bulleted and numbered lists, and tables, and looks at whether the page's images carry alt text. The word count follows a curve that flattens near two thousand words, so the first few hundred are worth far more than the last few hundred, and a page under a thousand words is flagged as thin.

Our verdict on the evidence

Evidence-backed Deep, comprehensive pages are far more likely to be cited than shallow ones, and missing information is a leading diagnosed cause of zero-citation failures. Coverage of the topic matters, not raw length.

Cross-engine citation-driver study, deep vs shallow content and freshness gatekeeping (arXiv 2605.25517) · Zero-citation failure taxonomy: contextual gap, intent divergence, information scarcity (arXiv 2603.09296) · Google Search Central guidance on AI features (no special schema needed, no ideal page length)

A page that covers its subject gives an engine more distinct facts to match a question against, and missing information is one of the leading diagnosed causes of a page going uncited. The check cannot judge how well a topic is covered, so it grades the proxies it can count.

How to fix it

  • Cover the questions a reader would ask next, beyond the headline topic; a page under a thousand words is flagged as thin, and the curve keeps paying until about two thousand.
  • Break long runs of prose into paragraphs; the check counts up to fifteen and credits each one.
  • Add at least one table for anything comparable (plans, specifications, prices) and a couple of lists for steps or options.
  • Give every image an alt attribute that describes what it shows, so it counts as media with context rather than a gap.
