PPC becoming more popular

I was talking yesterday with a friend of mine who has become acquaintance with PPC advertising recently. He learned from a book that other types of online advertising do not deliver the same kinds of benefits than PPC does. In fact, PPC advertising is becoming increasingly popular among advertisers and online marketing professionals for a variety of reasons. One of them, and perhaps the most important, is that PPC advertising is less expensive than other kinds or online advertising. Remember that in PPC you don’t actually pay anything until someone actually clicks on your ad. Moreover, research shows that up to 80% of people who are online use either Yahoo or Google. Therefore those people are exposed to PPC ads on a regular basis and, even though they don’t click on your ad, you may have made an impression on that person’s mind at no cost to you.
