On a New Rankings & Insights email I got today, one of our sites showed over 50 404 errors totally 49% of the site. When viewing the details, every one of the errors shows the URL in the following structure: http://domainname.com/page/domainname.com. I'm not sure why this is happening, but the site and all of its pages are fine.
We were having an SSL issue, but that is cleared up now. I just ran a crawl report and all checked out ok, but there were no result in the .csv file that concatenated the domain name to the end of the URL string. That doesn't seem like it would be the issue, but it's the only issue we were aware of with this site.
This is the only site of ours that this is happening to. Does anyone have any thoughts on why this happened?
Thank you.
