If you run a Blogspot blog that gets any kind of traffic at all, chances are that sooner or later someone will approach you about putting advertising on your site. Although turning your blog into a money-making venture can be an exciting prospect, you want to make sure you know how to properly put those ads on your site. Fortunately, most advertisers are quite savvy about creating basic HTML code that you can easily insert into a widget on your blog, so all you have to worry about is adding it to the blog's sidebar.
Step 2Log in to Blogger with your username and password. When you get to the Dashboard, click "Design."
Step 3Click "Add a Gadget" from above the sidebar widgets already present on your blog.
Step 5Paste the advertisement code you copied into the Content box, and then click "Save." Your widget now appears at the top of your blog's sidebar.
Step 6Drag the ad widget to the location you want it to appear in your sidebar, and then click "Save" on the Design page.
