Without my having changed anything about the kinds of content I posted or the days and times I posted, I noticed a significant drop in reach and engagement starting around September 20. So today I hunted around on the web to see if there was any news about FB having made major changes to Edgerank. What do you know:

Facebook recently changed its reach algorithm, some time around Sept. 25. I can only tell you how surreal it was to see engagement up by 33% and reach down by 40% this week. However, we’re all a bit in the dark as to what to do about this.

For instance, it’s hard to tell if Social@Ogilvy’s account that Facebook wants 80% organic and 20% paid content on a feed is true (although the fact that the company is now public makes me believe this.) On the other hand, PostRocket claims this has more to do with changes to Insights reporting and that reach is only slightly down. I have noticed reach numbers that literally make no sense (viral numbers lower than the amount of shares, or “1 person reached” when 200 people have liked a post), so things may shake out in the end.

 i just  read this…http://blog.hubspot.com/blog/tabid/6307/bid/33410/Facebook-Radically-Changes-Reach-Metric-How-You-Were-Affected.aspx   and it  raised  more  questions……  are  lots  of   fans  still seeing  the posts and   not  being  counted  because they  didnt   take any action?  i totally value  being seen   in  a fans  feed    even tho they dont do anything….   but is  that happening?  that possibility   seemed to  be in the hubspot  report….

i hope this  thread  stays alive…
