Came across one of our formerly top pages (dropped since panda) which I hadn't checked lately and discovered the page example.com/example.htm/ is indexed, but the page example.com/example.htm is NOT. Checking WMT, both show up, but WMT CLAIMS the example.htm/ page is LINKED externally AND internally via a REDIRECT from example.htm! This has NEVER been the case. Is this a new exploit going around?
Granted both resolve to the same page on that domain, because the .htaccess has not been set up to exclude this particular case, but why would WMT claim there is/was a non-existent redirect? I have now inserted the canonical tag on the page itself to hopefully fix this.
Any other explanations, solution suggestions?
