We manage content for several sites that have same folder and file names.
finding some of the pages in google index for one of the sites by doing a search for:
example of page found in the search results:
clicking on the cache link for the above example page and the address showing in the address bar is:
but when the cache version opens it shows at top of page in the grey cache info area a different root domain with same folder/file path as:
and the cache shows the www.differentsitename2.com version of the page. As mentioned the address bar refers to the www.sitenumber1.com page.
clicking on the "current page" link at top of cache page brings up the www.differentsitename2.com live version of page.
we expect that sometimes google filters pages out allowing the site with the most quality score or some other measure to have the page included, but showing cache versions of pages with completely different domains and visual content doesn't make any sense.
We did add a g-sitemap to one of the sites some time ago and wonder if somehow that causes something like this to happen, as it has never occurred before and these sites have been out there for 5+ years.
Has anyone else seen anything like this, or have thoughts on what is causing this? We removed the g-sitemap from the one site, think this will help?
