Hello, We have recently noticed on our webmaster tools that a lot of links with unrelated keywords and phrases have been indexed, on further investigation we have found out that someone has purchased a completely unrelated domain name that was once a fully functional website with established links and has created a permanent redirect from that domain name to our site. There are over a 1000 links now with unrelated terms and keywords linking to our site. Within a few weeks of noticing these links our site dropped for a couple of search terms (including one position for a primary search term that we were ranking position 2 for). Would this have a negative affect on our seo, and what can we do to neutralise the attack? Or would the drop in position be a coincidence and unrelated?
