I have a website and the URLS were constructed like so:
These were indexed in google and search results returned that pointed to these.
However, I've recently upgraded and reconfigured the website and now the URLS look like:
The original URLS are returning 404s. The site is linking to the correct URL structure internally, but Google is retaining the old URLS in its search results. I've updated and resubmitted the sitemap which only contains the new URL structure. Also, Google's webmasters tool is going slightly bananas at the fact there's now a spike in 404 errors in its crawl results.
- What is the best approach to get Google to remove the old URLS?
- Should I try blocking
- Should I be returning
301codes instead of
404for the old URLS?
