Hi guy I had the issue a long time ago and I thought I solved it. But I didn't cos today I find the same issue.
I have a wordpress blog with url like this:
http://www.example.com/post-title-etc-.html, in some posts I have images like this <a href=http://www.example.com/heres-image-name.jpg><img src=http://www.example.com/heres-image-name.jpg></a> and everything was OK until one day I found Google indexed some pages (over 10) like this:
http://www.example.com/post-title-etc-.html/heres-image-name which only had a image with adsense ads without any content.
I have no idea what happened, but apparently I got penalized in Panda. So anybody here please help me.
