I have a network of sites (70+) that use subdomains like this for a national site and regional branches:
Each of them have an About page that starts off with a short intro paragraph regarding the regional site and then the rest of the page is a canned, nearly identical description of the overall firm and its services.
My question is about the impact this system will have on SEO. Will search engines consider these About pages duplicate or spammy content because they are similar? We do need to present this info to our users on a regional level, but it doesn't make sense to write 70+ different about pages that are trying to give the same info about the overall firm and some unique info about the regional site.
