I am helping me dad with his website, and there are certain keywords i would like to have him rank for on google that would help out his business a lot. After using Google's Adword tool, the keywords i'm looking to ranking for have a range of between 1500-50000 searches for globally and in the US a little less. What would be the best way to optimize the website without having to spend a lot of doe. If anyone can provide guidance, i would really appreciate it. Thank you all!
