Static Content Density
Checks how much meaningful text ships in the initial HTML without JS execution.
What this check measures
We fetch the page with JS disabled, strip boilerplate, and measure the word count of extractable body text. Pages with under 100 words visible without JS are flagged as JS-dependent.
Why it matters
Even with SSR set up, you can still ship a JS-heavy page if data is fetched in useEffect or key components are marked `"use client"`. AI crawlers see only what is in the initial HTML — hidden content is invisible to them.
How our audit detects it
Fetch raw HTML. Strip script/style/nav/footer. Count words in the remaining body. Flag pages under a threshold (typically 100 words).
Typical findings
- error_outlineHero headline visible but the rest of the page loads via fetch.
- error_outlineKey content inside a `"use client"` component that renders async.
- error_outlineArticle preview list is empty without JS — content comes from a hook.
How to fix
Push main content into server-rendered parent components. Interactive widgets (search, filters, chat) can stay client. Rule of thumb: everything an SEO-competitive user would scan in first 5 seconds must be in raw HTML.
