Hello, Someone asked me for help with the following question. They have purchased thousands of links which are related to a similar theme. I don't know if he wants me to divulge the theme, so I won't mention it for now. What I will say is that each URL is related to a particular geographic area. So, for instance, he has xxxchicago, xxxboston, xxxCalifornia, etc (not all the URLs are that uniform, some may be xxxCity, others yyyCity, etc). He would like to put adsense on each of these URLs and find a way to bring traffic to them. In particular, he wants to know if he can cross link his URLs without getting penalized and if there would be any benefit to doing so. If there would be benefit to doing so, how should he go about it? A more general question would be how to optimize for all of these URLs. He wants to start out focusing on 600 URLs for now, perhpas optimizing 30 at a time (one potential strategy). Any ideas of how to do this? Thanks and be well. All the best, Moshe
