One of the networks I’m a part of, Advertising Moms Advertising Right, had a link to an interesting article about The Pick and Peck Method of Advertising
I had to laugh at this article, because that was me during my early days of Internet Advertising.  Basically she warns against spending $5 here and $10 there on advertising.  Instead she suggests that you should stick with an advertising plan for a long period of time before deciding on whether or not it works.  I couldn’t agree more.   You have to run an ad for a while to get a good feel for whether or not that market is right for your product.  Great article!
