TypePad Pro allows you to place advertisements on your blog to generate income from your blog. You can use a third-party ad service - SAY Media, AdSense, BlogAds, etc. - or sell and create your own ads.
Ad services will provide you with HTML for the ads which can be placed within your blog's design. Vertical ads can be placed in your blog's sidebar using the Embed Your Own HTML module at Design > Content for most designs. Information on adding content to the sidebar using TypeLists or Advanced Templates is available in the Knowledge Base.
You may also want to sell ads for your blog without using a third-party service. Advertisements may be a text link or linked image. You can use Embed Your Own HTML module to add custom ads to your blog as well.
We have more information in the article on including ads on your blog.
