We have collected a list of the largest and oldest pay-per-click search engines currently available on the web. While there are over 400 PPC search engines operating at this time, these 10 are the most popular that produce over 85% of all the PayPerClick searches. Keep in mind that while they produce the most amount of traffic, there is quite a bit of competition, which brings the bid prices higher than their smaller counterparts.

We have reviewed each of these search engines, based on its usability, features, popularity, and many other factors. We also allow our visitors to post their personal reviews about any particular search engine. You are encouraged to read them, in order to gain a better understanding if the search engine is right for you, as well as post your own, if you have any experience with them.
