Social media advertising is a form of online marketing that uses social networking sites as a platform to promote a product or service. Social media advertising includes paid ads that appear on social networking sites like Facebook or Instagram, as well as organic or natural posts that are not directly advertisements.
Paid social media advertising is typically done through sponsorships, where a brand pays to have their ad appear on a specific social networking site. Organic or natural social media posts are those that are not directly advertisements but still promote the brand in some way.
