I have been on the internet for a long time. I have never failed to get to the top of Google. The one time that I failed to do so was when I bought Google Adwords for a site. I am nowhere to be found on Google for this site. Top 5 on MSN and Yahoo but nowhere on Google. I would never by buy Adwords again unless I thought that I would not have any chance at getting to the top otherwise. Don't look at adWords as a boost to get you started. It is a permanent alternative (and costly) to the Google search engine. See it this way or you will regret it.
