Check
Content present in the raw HTML
Content present in the raw HTML is check A2 in the fifteen-point audit. The text of the page exists in the response body without executing JavaScript.
What counts as evidence
A word count of the raw response with script and style blocks removed, next to the count from the rendered page.
How to fix it
Server-side render the pages that answer questions, or prerender each URL at build time and keep the prerender in CI.
Where this sits
A is the group: accessibility, comprehension, or extractability. The groups run in order — a crawler that cannot reach the page never reaches the reading checks — so fix the earliest failing group first. The full definition of all fifteen items is in the standard.
