The likes feature allows you to display a likes area beneath your posts and pages that looks like this:
This is the Like button, and it’s a way for people to show their appreciation for posts they come across. It’s also a way for authors to show the world how popular their content has become.
It’s worth noting that you readers will need to log in to their WordPress.com account to be able to Like one of your posts.
Likes and Your Site
By default, the likes feature is disabled for Jetpack. Once enabled, the Like button will be displayed under each post and display the gallery of Gravatars for users that have liked your posts.
You can enable the module from the Jetpack activation screen and then configure where it should show using the “configure” button. The likes area uses the same settings as the “sharing” module to show the buttons.
Turn Likes On/Off on Specific Posts
If you’d rather, you can turn off the like button for specific posts. When editing a post, find the Likes and Shares module (you might have to scroll down to find it). It will contain an option labeled Show likes on this post.
You can toggle this on or off, just like controlling comments and trackbacks. When you’ve set it, either publish or update your post to save the change.
