first of all, i’m a little of an analytics nut, though i use apps I still do most from hand.
I just noticed something since september that my posts still get the same kind of response rates % which is pretty high, what you call ER is above 100% since ever.

Point though is that where 2 months ago I get within minutes 500 likes and then after few hours it would be around 1000 maybe and just die off after that.
Now posts get shown slower but for a much longer period of time, 3 days after being posted they can still rake in 10’000 more views or 300 likes

anybody notice this? I noticed some of my friends posts are being shown above others 3,4 days after having happened again even though I saw and liked it already.

I looked everywhere to find out the algorythm change in the facebook feed that could link to this but couldn’t find it.

if it changed and how I would plan my posts extremely different accordingly.

A friend of mine over at the wickedfire forums suggested they are experimenting with something like cred which could explain this

hej claudiayeah, though this has been a feature available for long.

I’m meaning some of my pages posts, they still get the same response rate, maybe a little more (as a normal upcurve should be) but the likes come in over a longer time spread means people don’t get to see the posts right away
but at different times spready over maybe 5 days

i have a few other pages but not with a significant audience like this  so it’s hard to measure

we have a long thread about just that here: http://www.socialmediaexaminer.com/clubs/facebook/forum/topic/reach-scheduled-posts/
