Google takes a while to process the keywords and to update the statistics as its cached.
People who have posted above me are correct now adays the bots look for keywords in content rich areas. Usually if you just spam the keywords it puts you on a blacklist.
Google was late to search. Facebook was late to social networking. Apple was late to the MP3 player. It's never too late. Just do it better
