Overview
When you migrate a website between platforms — for example, from Wix to another CMS — Search Atlas may continue reading data from your previous environment. This can cause issues with on-page optimization deployment and GSC sitemap sync that appear unrelated to the migration itself.
This article walks you through the steps to verify your OTTO pixel installation and restore accurate on-page optimization data after a platform migration.
Why On-Page Optimization May Not Reflect Your New Platform
After a CMS migration, Search Atlas may not immediately recognize your new platform environment. Until a fresh detection is triggered, on-page optimization scores and GSC sitemap sync may not reflect your current setup. This is a common occurrence after migrating platforms such as Wix.
Step 1 — Verify Your OTTO Pixel Is Correctly Installed on the New Platform
Before anything else, confirm that the OTTO pixel is present and correctly installed on your new platform. A missing or duplicated pixel is a frequent cause of detection failures after migration.
- Open your website in a browser and use your browser's developer tools to search for the OTTO pixel script tag in your page source.
- Confirm the pixel appears exactly once. If you migrated from a previous platform and the old pixel script was not fully removed, you may see two instances — remove any legacy pixel from the old platform before proceeding.
- After confirming the pixel is installed correctly on the new platform, navigate to your OTTO setup within Search Atlas and check whether on-page optimization deployment is now registering accurately.
Step 2 — Resubmit Your Sitemap in Google Search Console
After a migration, your GSC sitemap sync may be pointing to an outdated sitemap or may not reflect your new platform's URL structure. To resolve GSC sitemap sync issues post-migration:
- Log in to Google Search Console and navigate to Sitemaps under the relevant property.
- Remove any outdated sitemap entries associated with your previous platform.
- Submit your new sitemap URL generated by your current platform.
- Return to Search Atlas and trigger a re-crawl or refresh of your project so that GSC data is pulled in from the updated sitemap.
Step 3 — Escalate if Issues Persist After Pixel and Sitemap Verification
If you have confirmed the OTTO pixel is correctly installed and your sitemap has been resubmitted but on-page optimization or GSC sync still appear incorrect, a backend reset may be required. When escalating, have the following ready:
- Your website project URL
- The platforms involved in your migration (for example, migrated from Wix on [date])
- A description of the specific issue — for example, on-page optimization not deploying, or GSC sitemap sync not updating
- Any error messages or incorrect readings you are seeing in Search Atlas
