On my client websites we usually add a link that says: "Website Design, SEO, and Hosting By: COMPANY" with individual links for Web Design, SEO, Hosting, and COMPANY. We've been doing it for a long time not really thinking about it.
We just ran a backlink report for our site and it looks like in some cases we have over a 1000 links to our site from an individual client site (this is 1/4 of our total backlinks!) and we also now show up for that client's keywords as well.
Can this be impacting our rankings or dropping us lower for our own keywords? Should we worry about the number of backlinks and trim them down?
