The company I work for are considering becoming affiliated with another company in the same sector, principally to drive extra traffic to our site. However in recent weeks we have noticed that the other site has been dropping in the search rankings for our main keyword. They have gone from being firmly established on page 1 to page 4 and page 5.
For the same keyword our site is on page 2, my question is, will becoming affiliated with a site that has recently taken a hit in the SERPs have a negative effect on our ranking? Will Google be able to see a relationship between the 2 companies and penalise us by association?
