The On-page Checklist is there to help you make sure your post has the highest optimization score possible before you publish it.

To get to the On-page Checklist, simply open up the post you want to optimize and click Optimize in the lower right corner of the dashboard. Then, click Checklist.

This will open up a list which will help you make your post more friendly to both readers and search engines.

Green checks means your post is optimized for the item in the list. Red x's means it's not.

For instance, in the example above, adding a "Click to Tweet" box in your post will give that item a green check. Your post will then be better optimized to rank on Google!
