Maybe you new insights aren’t in…maybe these are old….? 

@johnpristine This is because not all your fans see your posts ! 29 out of 60 is great! Usually, on big pages, the reach per post does not exceed 10 to 15%Think of the reach as the open rate of emails, not every one opens emails, not everyone connects on Facebook ans see post every day!

@emericernoult Hi Emeric,  Im not sure I understand that.  If I post an update to my page, does it not appear on all of my “likes” pages, therefor it has reached them.  I suppose what im asking is How does Facebook measure a reach.  Is it someone that logs into their facebook page, and then does that imply that approx 30 of the people that like my page not use facebook since the date of the post.

Verrry Interesting

@devanianjali   Well done, Remember me when you make your first $million

@johnpristine The reach means all your fans (unique fans) who have generated an impression of your post on their newsfeed or ticker. So, in a nutshell, you will not reach the fans who did not use Facebook 24 hours after your post, the one who have hidden your post and the one who have too many friends or who like too many pages for your posts to be displayed on their newsfeed (remember your post is competing with their friend’s posts and the other pages they like.)

Great question @johnpristine

Facebook has “Edge Rank” which is sort of like how Google decides if your webpage should appear in a list of results or not. On Facebook Edge Rank is a combination of factors related to, as @emericernoult pointed out, time but also affinity  (how interactive is a fan with your page) and weight (the type of post made, i.e., is there a photo, is there a video, is it a status update). 
Your Edge Rank decides is your update should appear in your fans’ feed. Just because they are a fan, doesn’t mean that they’ll see you post. You are rewarded for the level of engagement you have with your fans with visibility in their feed, and your reach number is the barometer. 
Reach also indicates which of your fans’ friends saw the post as well if that fan shared it or did some other interaction so reach isn’t a direct number related to your number of fans only. Hope that helps.

@johnpristine you did a good job of summing all that up:) 

Also, if you have a blog or newsletter, you could send an invitation to “like our page and get a free xyz product…” Or “like our page and we’ll send you a video series to help you do xyz…”

Iactually have a question along the insights as well, and instead of start a new topic, it fits pretty well with this one.

When you export the data on your insights page for any time period (lets say 30 days for example) I get the report and the first 3 columns are: Daily People Talking About This;Weekly People Talking about This; and 28 days people talking about this.

I can’t seem to figure out the difference between the 3. When I multiply the first column of numbers  by 7 (to get what I think would represent a weekly figure) it is much smaller than the number in the weekly column. The same with Weekly number to 28 days column. I can’t get the math to work out.

I am just trying to see what my total “People talking about this” for a month is so I can share that data with my boss. I feel like the Weekly and 28 day numbers are incorrect and generally I resort to the daily number, although low.

My Question is – does anyone know how to interpret this data and am i correct that it doesn’t add up, or what am I missing?

Any help would be greatly appreciated!
Thanks,
Megan

Yeah the report is pretty indepth, but I am not sure what to take literally from it.
Don’t want to give numbers to the higher-ups that are not accurate. Any help would be amazing!
