Explanation

Liking a Page changes the Heart icon pill from blue to gray and increments the counter of likers displayed on the Page and in other several places such as:

• in the table of Page likers, 
• in the table of your liked Pages, 
• in the Page Index table.

It can also send a notification to the followers of the liker (the people who follow the person who liked the Page) and to people watching the Page, if they have enabled those notifications.
