Walkman - I tried that link you gave but for one of our websites and found a picture stolen from us and posted on Wikipedia. The image has had its copyright watermark removed:
"(Removed watermark from uploaded image)"
Under the "File Links" it states:
"No pages on the English Wikipedia link to this file. (Pages on other projects are not counted.)"
It lists our website URL but you cannot click on it. But somehow G found it and I wonder if this is a real back link and whether we should leave it?
Is this one reason Wikipedia outranks so many sites?
