Sponsored posts on Facebook/Instagram

A Facebook sponsored post is an ad created from a post on a business page. The post originally appears on the company’s timeline as organic content. The company pays to promote the post to boost visibility and reach new people.
Sponsored posts are clearly labeled as advertisements and tend to stand out from the rest of the content. They can appear in a variety of locations, including users’ newsfeeds, stories, and the Facebook sidebar.
You can boost a Facebook post for as little as $1 USD per day. If you spend more, you’ll reach more people with your ad. You can type in a specific amount or move the slider to set your maximum total budget.
