I have two websites (simple business sites) that each rank very well for two separate keywords (city based). Each website ranks well for one city (same keyword). I'd like to get rid of one of the sites (aka 301 redirect) to the other site. What would that do to my rankings? I'd like just one site to rank highly for both cities. Neither site has the city in the domain name. The rankings I achieved were purely due to link building and time.
