Common Javascript SEO Concerns with Solutions by JetOctopus

On-Page IssuesUse our technical audit section to fix SEO issues caused by JavaScript - missing titles, meta descriptions, duplicate content, load time or 404s.

Indexation & Crawling ProblemsWe use headless Chrome for crawling the same way Google does, to detect blocked resources and hidden JS content.

JS vs Non JS ErrorWe crawl each page twice - with and without JavaScript, to identify differences in content, links or metadata. JetOctopus helps you detect JavaScript-rendered vs HTML mismatches, surfacing rendering parity issues between raw HTML and the final DOM, so you can preview pages exactly as bots see them.
→ Compare what Googlebot and AI crawlers actually see when accessing your pages.
