hiya, newbie to the the forum here heard a wee bit about adwords here and there and was wondering how they work? they can get more people heading to my site, right?

They are basically paid advertising...Pay per Click! (PPC). You tell Google how much you wanna pay for your advert and according to how much you want to pay in comparison to how much everyone else is offering, will depend on how far up the list at the top and right you appear on the search result page. Loads of info at www.google.com/adwords
