Blend-in Ads

To maximise the CPC earnings, you must make your ads blend-in with your blogs/website background color. Dont use striking color such as solid red or yellow unless your blogs or website background using the same color. Let your ads background color and your blog or website background color be the same so the ads you placed will not be too obvious to visitors eyes.
Choose the best color for your blog background(usually white or black). Placement of the ads also play major roll on increasing the CPC earnings.
