In searching thru our data to try and find clues to our downfall in position, I've come across numerous spam type sites each linking to a different keyword on our site. I'm not sure if it's the cause of the downfall, or a contributing factor to it, but I doubt it is good for us.
Many of these sites are blogs with generic product names like widgetsrus.net. They are heavy with adwords and/or affiliates. The link to our site is a product or category related to the name
of the blog, such as red widgets, and appears on the blog under headings such as More Info, Related Sites, and Helpful Links.
The same link appears on every page of the blog and some of them have many thousands of pages.
What do I do about this? Is this important enough to be part of my site repairs? If they are doing something wrong, what exactly is the wrong? It's not as if they are using our site name or original product descriptions which would create an intellectual property infringement. Can you prevent somebody from merely linking?
Of course, the Whois data is all hidden so it's not even easy to contact them and ask them to stop.
Could these be related to our downfall in Google?
