I'm reviewing some errors in Google Webmaster Tools / Search Console.
I'm getting a lot of 404 errors for pages that don't exist such as:
example.com/page12.php
example.com/page111.html
example.com/wpimages/34f126905bc8Pc7454118.xml
My site doesn't use WordPress or a /page
URL structure as the above would suggest.
I looked to see where Webmaster Tools says they are linked from. I found that they are being linked from a old site which I now 301 to this current site. Somehow it must be trying /page12.html
on the old site and because the old site has a site wide 301 to the new site it is causing the crawl errors. It doesn't actually matter if its doing this as its a "bot only bug" which users would never see, but could that effect our rankings?
