Ad codes from sites like google adsense, adbrite and other ad companies are in javascript format and when you try to embed these codes in your layout through Edit Html in Blogger. This code doesn’t work and usually get an error or if no appears you do not see the ads on the site.

This error occurs due to the xml format of the layout so you have to convert the code in the xml format. This task can be accomplished easily by putting your ad code in the following link:
