They're ok...but you have no content on that page. So, the ads may not be appealing to your visitors....why would they click on ads about search engines, when they came to your site to search their info ??
Are you doing the same every now and then here at DP? you seem to have been around for a long time but you also seem fond of asking for something that is so easy to understand from one look. Please ask of more of questions regarding your site that we can also learn from and others can give a healthier suggestion...It's too obvious.
