# Why Can a Site Migration Suddenly Reduce the Number of Indexed Pages?

After moving a site to a new domain, changing its URL structure, or switching platforms, it’s unsettling to see the indexed-page count fall in Google Search Console. Some missing URLs may be expected, but others are pages we still want people to find.

When a drop follows a **[website migration](https://yourviews.mindstick.com/view/86093/know-about-the-website-migration-for-your-brand-image)**, how do you tell normal reprocessing from a problem with redirects, robots directives, or internal links? I’m especially curious about which [Search Console reports](https://yourviews.mindstick.com/view/86456/what-google-search-console-insights-is-and-how-these-reports-can-help-you) are most useful before making another round of changes.
