Facebook breaks down how people were reached by a Page’s post by categorizing the interaction as resulting from Organic (in the newsfeed because the user Likes the Page), Paid (the result of an advertisement) or Viral (in the newsfeed because someone else in their network interacted with the post).

Facebook Insights allows marketers to understand which marketing methods are most effective. In the How You Reached People section, you can see a graphic chart of how many people were reached by your organic, paid and viral Facebook content.
