Naytev ushers your content through a combination testing and posting process that allows your content to come into contact with three types of engagement: 

Paid Engagement: all activity from people who view and engage with your sponsored content. This includes clicks, reactions, shares, video views, comments, and impressions.

In the testing phase, you also accrue a secondary type of engagement called "Organic from Paid."

Organic-From-Paid Engagement: is the activity that's generated from the extended social circle of an individual who initially interacted with your sponsored content. This includes clicks, reactions, shares, comments, impressions and unique impressions. 

When you publish the best message to your page, Naytev carries through Paid and Organic-from-Paid Engagement earned during the testing phase. Your content, now an organic post, has the engagement earned from the testing phase already "seeded" on it. This provides social proof for your content and leads it to generate even more Organic engagement after posting to your Page. 

Organic Page Post Engagement: all activity from people who view and engage with the content you've posted to your Facebook Page.
