There are a couple of differences to take note of, however. The free service gives you access to the STST. The way that overture will make a profit here, since the service is free, is by selling you the best key words. Theres nothing wrong with that everybody has to make a profit to stay in business. The Keyword tool on Google gives a complete different set of Keywords. They dont sell the keywords so it makes you wonder which list of Keywords are the best.
If you have not yet made use of Overture, this is certainly a tool you should take the time to explore. Bidding very high on the best Keywords can move your advertisements into the top ten search results in the major search engines very quickly.
We all know that search engine optimization (SEO) is the key to making sales and making use of Overture is one of the best ways to accomplish that task.
Overture was originally named GoTo.com. It changed its name to Overture in October, 2001 and was purchased by Yahoo in 2003.
