Most effective auto-posting apps for Facebook Pages

From Study: Auto-Posting to Facebook Decreases Likes and Comments by 70% @ insidefacebook.com

Many companies, public figures, organizations, and news outlets (including our own) use auto-posting apps to create Facebook Page updates by syndicating their Twitter posts or converting their blog post headlines. This increases efficiency by relieving the admins of these accounts from having to copy and paste headlines and links from one platform to another.

Facebook, however, depreciates third party applications over manual posting. According to a recent study by edgerankchecker.com, engagement ratio overall drops at least 70% per post. Check this infograph for an overview of popular auto-posting apps:

[Update] From Management Tools From Having Posts Hidden in News Feeds @ insidefacebook.com

We’ve now learned that Facebook maintains a secret whitelist of companies that are exempt from having content posted through their publishers consolidated across different Pages and clients. This protects them from a reduction in news feed impressions. The whitelist includes some top enterprise Page management tools from the Preferred Developer Consultant program including Buddy Media, Vitrue, Involver, Context Optional and Syncapse. Facebook has forbidden those included from discussing the existence of the whitelist. Facebook has confirmed with us that “trusted partners” are having their posts treated differently.
