Change the Position of the Google AdSense on My Blog
Google AdSense generates JavaScript code used to display ads on your site. You must choose the location on the Web page where you want the ads to display. Each blog has an interface where you can edit the raw HTML. If you want to customize the location of the AdSense ads, you can add the JavaScript code to a specific location in your posts using the HTML editor in the blog's dashboard.
Step 1:
Open a Web browser and log in to your blog's dashboard. Open the post you want to use to position an AdSense ad. Click the "Edit HTML" tab or button that lets you view the raw HTML data for the post.
Step 2:
Open a separate Web browser tab and log in to your AdSense account. Click the "AdSense Setup" tab and choose an ad size and color. Click "Generate" to get the AdSense code for your ad.
Step 3:
Copy the AdSense code from the Google ad generator. In the tab that contains your blog post, paste the AdSense code in the location where you want the ad to display.
Step 4:
Save the changes to the blog post and open a third browser tab to review the post content. If you are unhappy with the placement, you can cut and paste the AdSense code in the blog post editor to move the ad until you are satisfied with the placement.
