Local search algorithm: Local Search is a type of search that is triggered when people search for things nearby, like a restaurant or movie times. The links are likely there to help Google find the brand new spam sites and get them crawled and eventually ranking. The local search algorithm is not the same as the algorithm for ranking non-local keywords. So I changed my browser user agent to identify itself as Googlebot but the spam site still redirected me. So I used Google’s Rich Results tester to visit the spam site and record the HTML of the page.
