There is a site in my niche that is ranking well for a large number of cities and towns. Basically they take the same exact content and add the city name to each page in several locations. They also add in the zip codes for each city. I would think they wouldn't rank too high because of having very similar content on each page but they are on the first page for many of the cities in the US. Since the last update, they have been gaining in rank. This sounds like an easier way to rank then what I'm currently doing which is manually writing content for the major cities. They have thousands of these pages and I don't think they do much back linking outside of their site. I was thinking of doing the same kind of thing to test it out. How should I go about changing the page so each is different? Also, is anyone else having success with this? If I do this, should I space out when I publish the pages?
