When auditing websites, JavaScript rendering plays an important role in how crawlers interpret and display content changes. The Search Atlas Site Auditor supports JavaScript rendering today, and this article explains how it currently works as well as a known limitation that affects certain OTTO deployments.
⚙️ Current Limitations of the Search Atlas Site Auditor
The Search Atlas Site Auditor supports JavaScript rendering. However, there is a known limitation when OTTO is deployed via the manual_script (pixel) installation.
This means:
- The auditor can crawl and analyze pages with JavaScript rendering enabled.
- When OTTO is deployed via the pixel (manual script) installation, the crawler may currently display the original source titles rather than the OTTO-deployed titles, even when JS rendering is active. This is a known issue under active remediation.
🧩 Example:
If OTTO has deployed updated title tags or meta descriptions to your site via the pixel script, these changes may not be reflected in the Site Auditor report even though they are live on the page.
🚀 The Search Atlas Approach to Fixing This
Our team is actively working to resolve the known issue affecting OTTO pixel deployments so that the Site Auditor accurately reflects OTTO-deployed content.
Once resolved, this update will allow the tool to:
- Accurately detect OTTO-deployed titles and meta descriptions
- Audit dynamic website changes consistently
- Provide more comprehensive and accurate crawl reports
✅ Important Note:
Even though the Site Auditor may not currently reflect OTTO-deployed changes for pixel installations, Google can. Search engines like Google use advanced rendering engines to process JavaScript content, meaning that any changes made via JavaScript can still be visible and indexable by Google's crawlers.
So, if the auditor doesn't reflect a recent fix, that doesn't necessarily mean the issue remains unfixed on the live site, as Google may already be processing the JavaScript-rendered version correctly.
Website Studio users: If your site is hosted in Website Studio with a connected custom domain and OTTO deployments (such as meta descriptions or title tags) are not applying as expected, OTTO behavior may differ from external sites that use the pixel script. Please verify your script installation, confirm your custom domain is properly connected, and contact support if deployed changes are not being reflected.
🔮 Moving Forward
The Search Atlas development team is committed to continuous improvement.
Upcoming updates will refine JavaScript rendering accuracy and resolve the OTTO pixel limitation described above, keeping the Site Auditor aligned with other industry-leading crawlers.
In the meantime:
- Continue optimizing your site for search engines that already render JavaScript.
- Rest assured that JavaScript-based updates on your pages — including OTTO deployments — are still recognized by Google.
Stay tuned for future releases as we make the Search Atlas Site Auditor even more powerful and precise.
