Facebook pages are far more detailed than Twitter accounts. They allow a product to provide videos, photos, and longer descriptions, and testimonials as other followers can comment on the product pages for others to see. Facebook can link back to the product's Twitter page as well as send out event reminders. As of May 2015, 93% of businesses marketers use Facebook to promote their brand.[43] A study from 2011 attributed 84% of "engagement" or clicks to Likes that link back to Facebook advertising.[44] By 2014, Facebook had restricted the content published from businesses' and brands' pages. Adjustments in Facebook algorithms have reduced the audience for non-paying business pages (that have at least 500,000 "Likes") from 16% in 2012 down to 2% in February 2014.
