I’m having an issue with Google Search Console. My old site pages are still showing up, causing errors during indexing because those pages don’t exist anymore. I rebuilt the site, and not all the old links are in the new sitemap.
How can I clean this up so only the new pages get indexed? Do I need to delete the entire property and start fresh?
Those errors aren’t really a problem. When Google tries to crawl the old pages, they return a 404 or similar error, which is normal. GSC just reports what’s happening.
Your sitemap should:
List all the pages that currently exist.
Avoid including links to pages that no longer exist.
If that’s already the case, you’re good.
What you probably see as an ‘error’ is likely just a ‘not indexed’ report. That means Google is already focusing on your new pages.
Deleting your GSC property won’t change how Google crawls or ranks your site. GSC is just a reporting tool.
Here’s what I’d recommend:
Crawl your site using a tool like ScreamingFrog to find any links still pointing to those deleted pages. Update or remove those links.
Check backlinks pointing to deleted pages. You can use tools like ahrefs. Either update those links or set up 301 redirects.
In GSC, check where Google found the old URLs. That should give you clues on how to handle them.
Deleting the GSC property won’t stop Google from crawling. Any link found online will stay on Google’s radar until it’s permanently dealt with. Either publish new content on those URLs or set up 301 redirects to point them elsewhere.
