An endorsement of a profile, page, or post on Facebook. Once a user Likes a Company Page, they may see subsequent posts from that company in their newsfeed.
Why Are Facebook Likes Important?
Facebook Likes are an incredibly important social recommendation for companies. Fans may Like the Page, as well as specific posts by the brand. When a user Likes a Facebook Page or post, this information is shared with the people in their network. Users may also consider the overall popularity of the Page, or number of Likes, when making the decision to follow the brand.
Likes are an interaction with the Page and the more a user interacts with a brand, the more that brand's content will appear in their newsfeed.
