Refreshing old URLs causing traffic loss?

I've been keeping an eye on traffic and rankings for a while now and I'm seeing more and more sites that refresh old URLs and then watch their organic performance tank. This pattern keeps coming up in my reports.

-> I pulled data from Google Search Console to see indexing status before and after the refreshes.
-> Analyzed the number of URLs re-submitted to search engines and any crawl budget impacts.
-> Reviewed the site's internal linking to make sure old URLs still pointed correctly to new content.
-> What actually correlated was increased server errors and slower indexing times, not the improved relevance the blogs promise.
-> Duplicate content signals got triggered on several pages during the process, which hurt visibility more than expected. New unrelated or semi-relared URLs now being pushed upwards. Totally unintended cannibalization.

Anyone else notice this?

Check your internal links after the update. Make sure old links are pointing to the right pages and not to outdated URLs.

yes check your internal link and if your site needs any update do that it works too
