The point I am trying to make is that I think New Internet Users are using there ISP's homepage search when they first go on-line and then after learning about the likes of Google start to switch and then set the browser to go straight to Google. I sell advertising on our site to people in the Widget trade and speak to quite a few each week. What many are saying is that they are not happy with intrusive internet advertising especially from their ISP's and many have already switched to using Google for that very reason.
Could the reason maybe also be that the nature of site and the type of people searching for this type of of information could be a little older? Our profile will reveal more.
