Facebook dropped jaws in February when the company announced during its first marketing conference that the average news feed post is only seen by 16 percent of the eligible users. Then Facebook announced its Reach Generator product as a way for brands to make sure their Facebook messages can reach up to 75 percent of their fans within a month, but that product has only been available to a small number of marketers.

Now social advertising company Adaptly says it has an alternative product available to all brands right away: Evergreen.

Adaptly is one of a handful of companies to have emerged in recent years promising brands a more efficient way to advertise on social media sites without buying from the Facebooks and Twitters of the world directly. With Evergreen, the company is taking a different approach from Facebook's Reach Generator. Rather than repromote content within the Facebook News Feed, it takes content posted to a brand’s page and spins it into a paid ad on Facebook.
