Can crawlers see your content without running JavaScript?
Search engines render JavaScript: slowly, and not always. Google does index JavaScript-generated content, but on a queued second pass, while AI crawlers, social scrapers and fast fetchers mostly do not run it at all. If your price, name or description only exists after a script runs, a lot of readers never see it.
Reads raw server HTML on a set of key pages: the same bytes a crawler receives first. Saved to your account if you are signed in to a paid plan.
How this check works
Shipwork fetches your pages and inspects only the raw HTML, before any script runs. It reports product prices or names that are absent from the source, and pages that look like a bare JavaScript shell. When the essentials are missing, the paid rendered crawl runs a real browser to measure exactly what is built client-side.
