How to Place an Ad in the Middle of a WordPress Post

1. Start a new post in WordPress by clicking 'Posts' on the left side of the Dashboard and then clicking 'Add Post.' Type the post so that it is ready to be published. If you have already published the post, click the 'Posts' menu and then click the 'Edit' link below the name of the post you want to change.
2. Open a new browser window or tab and copy the raw code for the advertisement that you want to display. For example, with Google's AdSense service, the code appears in a new window when you create a new ad unit and click the 'Save and Get Code' button. Highlight the code with the mouse pointer, right-click the highlighted code and select 'Copy.'

3. Return to the browser tab displaying your WordPress post, and click the 'HTML' tab at the top of the post edit screen to display the raw code for the blog post.
4. Click to place the cursor at the location in the post where you would like the advertisement to appear.
5. Right-click with the mouse, and select 'Paste' to place the code for the advertisement at the location of the cursor.
6. Click the 'Publish' or 'Update' button on the right side of the page to publish the post with the embedded advertisement.
