@pollyb Interesting question polly, really tough to answer unless experimented and experienced. Let’s test it now. Thanks for initiative. By the way, any special reason for this question or just for curiosity? 

@pollyb

Shares are a very important aspect of EdgeRank. Posts from “Your” page instantly goes into the “Sharer’s” feed for all of their friends to see. This can cause a viral effect on Facebook.

The trick is to get the fan to “share” a photo, video, etc. with their friends. Make the content something their friends would actually want to see.

Shares, comments and to a lessor degree likes, will tell Facebook that fans are interested in your page content.

Therefore, your number one goal is to create engagement with your content. Engagement builds “Your” EdgeRank, EdgeRank builds exposure in the news feed.

Intuitively, I would think your content on some other page would have to be actively engaged in the same manner for them to increase EdgeRank.

Hope that helps.
