Common Javascript SEO Concerns with Solutions by JetOctopus

    → See how rendering speed impacts crawlability and visibility for both search engines and AI bots.
  • On-Page Issues

    → Understand which content elements remain invisible to crawlers and AI bots due to JS rendering.
  • Indexation & Crawling Problems
    We use headless Chrome for crawling the same way Google does, to detect blocked resources and hidden JS content.

  • JS Console Error
    Use our JS console reports to find script execution issues affecting rendering and indexation.

  • Rendering Issues
    Compare JavaScript and raw HTML versions to detect changes in titles, meta descriptions or indexing behavior.
    → Identify rendering gaps that affect SEO and AI visibility.
