Insert ads in your post at the place of your choice in a single click. Adds buttons in your toolbar to place ads while writing your post. Now Inserting ads in your post is even simpler than underlining a word. All you need to do is put your Google Adsense code into the boxes provided and then click the corresponding button in tool bar to show the ads at place of your choice in post. Remember showing an ad at the right place in your post can result in much better revenue as compared to placing it randomly or some fixed place. You can also use ad-codes from other providers to show with adsense.
<h3>Note</h3>
A link from your blog to www.yuyuh.com is highly appreciated. Please note that use of Ads Code 3 & 7 also adds a powered by link in the bottom. If you don’t want to place this link in your site, use only other codes. Other codes will show only your ads and nothing else.
<h3>Demo</h3>
A live demo of the plugin at work can be seen here.
