Pay Per Click
For a web based business or even those websites who dont actually sell anything always need targetted traffic which is the only route to success be it building a community or selling something to the visitors, all these objectives can only be achieved by getting very targeted traffic.The best way to get instant and excelent targeted traffic is Pay Per Click. Although cpm based advertising is considered to be equally good but it is in my opinion good for those companies which are trying to create a brand image rather then getting targeted traffic to thier website.Apogee Search Blog has got some very very interesting posts about insight on the whole pay per click method of getting traffic.Adwords is passe now and Apogee is the most in thing now with thier business rising by the day they must be doing something right and to be honest they have to be doing a lot of things right for me to sit here and write about them as I dont move my lazy ass for ordinary things so take my word for this 
best pay per click traffic comes from apogee search.
