One thing to remember is that if your ad looks like an ad visitors are going to avoid it. Our main focus should be to blend the ad with the content. We will dress up our ads in a legitimate way as permitted by Google, to achieve it. Google gives you a lot of options to format your ads.

Following tweaks will help in maximizing the clicks of your ads:

• Formatting of Border: People are used to see borders around the ads. As soon as they see a border, they recognize it as an ad and their eyes are trained to ignore them. So for best results remove the borders around your ad blocks.
• Formatting of title, text and backgroud: Tweak the title, text and background of the ad block to match the text on your site.
• Formatting of link colors: People associate teh blue color for link and are more likely to click on them. Use blue for link color.
• Formatting of URL color: Presence of URL along with the link makes it obvious that it is an ad. To make the URL less prominent make the link color like rest of the text in the ad.
