My companies website dropped from the first page of google's results beginning in August. It has held this position for several years.
I use google webmaster tools and I noticed that my sites keywords were Microsoft,Adobe,windows etc(not at all what the site is about).
What I found was that someone had hosted a page with the http://example.com with hidden links and text. So about three weeks ago I did a 301 redirect to correct the problem and in webmaster tools I verified ownership of both domains and requested they use the www version.
At first the http version in webmaster tools showed the correct keywords but since the last crawl it now shows the hijacked keywords once again.
My question is how do I get rid of the offensive page?
Thanks in Advance
