Ad Injection is one of the fastest developing Ad plugin for wordpress. I am using it and marked as must have wordpress plugin. It has some great features like inserting ads in just below the heading and above post footer including various type of restrictions to meet the policies of advertising company like Adsense. You may also perform split testing using the same plugin.
Features of the plugins:
- This is a really lightweight plugin and so very less impact on the performance of Blog.
- It can inject almost any type of ads from various providers like Adsense, Technorati Media, Buysellads, clicksor and others.
- You can perform ad split testing (A/B) or simple ad rotation.
- Unlimited ads can be placed in the widget areas.
- random ad can be placed in the post body.
- Ads can be restricted based on the referrers including search engines.
- From the version 1.x.x ads can be placed anywhere by modifying theme templates.
- Ads can also be restricted on other factors like category, tags, author and post Id.
- additionally ads can be restricted on lengths of the post.
- Ads can be blocked on any page/posts by simply adding some tags
Something Still missing:
- Lack of 125x125px ads widget. Since it is one of the most famous ad format these days, I think the developer should think on this.
How to add four 125x125px ads and one 160x600px ads in side bar?
A lot of people mostly newbies have asked me how I have added four 125x125px ads and 160×600 px ads in the sidebar of my blog. Its simple and use the following codes for the same:
Add the following code in a text widget to your theme:
<div id="ad125">
<div class="adslot 1"><a href="http://example.com/url1" rel="nofollow" target="_blank"><img src="http://example.com/125x125.png" alt="" border="0"/></a></div>
<div class="adslot 2"><a href="http://example.com/url2" rel="nofollow" target="_blank"><img src="http://example.com/125x125.jpg" alt="" border="0"/></a></div>

Hi Anand, looking for this info to integrate google adsense to my blog, but had a dilemma whether its safe to use since google is very strict for Indian publishers. Now am satisfied and use it on by blog. Thanks for the info.
