Pay Per Click advertising is probably one of the best marketing strategies to increase your ROI. Often times you hear that you can get clicks for $.05, $.10, etc., but for the most part those days are gone. Pay Per Click has become increasingly competitive and the longer you wait to jump into the game the more you are going to pay.
Some of the highest paying verticals include education, insurance, law, and real estate. Although these industries can be fairly pricey, these clients find that even at higher CPC costs, their Cost Per Acquisition (CPA) is still significantly lower then other advertising outlets (yellow pages, direct marketing, tv, radio, etc.).
