Google seems to have penalized one specfic page of my web site. The rest of my web site has a page rank of about 3, and it ranks #1 on yahoo and #1 on bing yet on google one main page of the site (that is linked to from all the other pages), has a lot of original content on it, and is well aged (used to rank on the first page of google) shows no page rank and can't be found in the search results. I have not made any changes to the page for years, so why is this one page seemingly penalized? Also, the page is for a clickbank product of mine, so there are other people creating "hop links" (clickbank's way of linking to the page as an affiliate) that might look to google like duplicate content of that page. Please Help! Thank you!
