Welcome to the Q&A Forum

A client of mine had purchased a lot of domains. They all start with the same keyword following by "in" following by a cities name. The cities are all the cities around their location. They had the pages set up to all look the same with very small differences in content. A bunch of duplicate content. All of them have a DA of 8 and PA of 19. There are 35 of them total. They get roughly 30-60 hits a month each but it's mostly all spam. The idea was for users to type in [keyword] in [city] in Google and these websites show up. A competitor of my clients had done something similar which was working for them. The main website (separate of these) gets ~1500 visits per month of non spam traffic and gets ~10 referrals from these websites. What should be done with these domains? Chalk it off as a bad idea and have them 301 to the main website until they expire? Or can they be changed into something useful? If so, how? Any ideas would be greatly appreciated. Note: I did search for this similar topic but it was hard to search it out and I did not find an answer. Thanks!
