I’ve got a site that’s gotten the “Googlebot identified a significant increase in the number of URLs” error.
It looks like the bad urls (returning 404s) are all of the form
XXX-y makes the URLs work fine. (I thought it was an off-by-one error at first, but sometimes
y needs to be significantly more than 1).
It’s not immediately apparent that it’s due to deleted posts, which was my next guess.
Perhaps if the page number is greater than the number of pages there should be a 301 to page 1 or something? (I don’t pretend to know anything about SEO). Or should I tell them just not to worry about those 404s?
