Yahoo Sponsored Search

[Modee]

Formerly known as "Overture," Yahoo is second only to Google.

Again, this is one of the most cost effective ways to drive traffic to your site. The key is in developing the right ad, with just a few words that makes your point for WHAT you are doing and WHY people should click to go to your site...

and

choosing the right keywords.

Now they do Bing ads. No more sponsored search. I no longer advertise with them though - strictly Google Adwords / Adsense.
