One of our competitors has a horribly old design. Hasn't been touched or updated and has looked exactly the same for the past 15 years. They are doing well BUT, I don't think they have also done anything to attract attention to itself like link changes. My bet is anyone at Google took a look at that site they would consider it abandoned and maybe manually hit it. We have looked always much more modern than that site but we tinker with changes and try to improve the site for people. Ha, silly us.
