In this page select to drag-and-drop a “Text” widget onto your registered sidebar.

Then you should add a title (in our case – Advertisement) and right under it the actual code that you have obtained from Google. Finally, click on the on the “Save” button right under it.

Well done! You have just added your AdSense code to your WordPress blog.
