How to Put Ads in the WordPress Footer

Create Ads
1. Sign up for an ad network. Google AdSense is one example. Log in to the ad network if you are already an ad publisher.
2. Create a new ad. For example, click the 'My ads' tab and 'New ad unit' in Google AdSense.

3. Enter a name for the ad, and choose a size and type. Select the formatting for the ad, such as colors to match your theme. Save the ad and get the ad code, which is usually JavaScript code. For example, click 'Save and get code' in Google AdSense.
4. Highlight the code with your mouse. 'Ctrl' and 'C' to copy the ad code to the clipboard.
Install Plugin and Insert Ad Code
5. Sign in to WordPress as the 'admin' user. Download and install a plugin that allows you to add custom code to the WordPress theme footer.
6. Click 'Plugins' from the menu, locate the plugin you installed, and click 'Activate' beneath its name to make it active.
7. Navigate to the options for the plugin. For example, click 'Post Footer' under 'Settings.'
8. Press 'Ctrl' and 'V' to paste the ad code in the box provided by the plugin -- in the 'Ad Code' box, for example. Click the button to save your changes. Click 'Update Options.'
9. Create another ad, copy the ad code to the clipboard and paste it into the custom footer to display more than one ad in the footer. Click the name of your blog to view the blog and check to make sure the ads are properly displaying in the WordPress footer.
