First off I'm very grateful for what I learned on this site. I've been able to bring my website from page 3 all the way up to page 1 position 1 for a local cleaning service in Anchorage Alaska. I need to know how to stay at the top. I have done article marketing blog commenting forum posting as well as keyword optimized my homepage. it took a while but I'm at the top. at this point I'm kind of afraid to do anything because I don't want my rankings to be negatively affected. what are some solid bulletproof ways to maintain my position?
