Multiple Facebook Fanpages on 1 account or 1:1?

Anyone know if its equal organic reach if you have 1 facebook account with 5 fanpages and you post content on all 5 pages from same user?

Or will reach be higher if you create 5 facebook accounts amd dedicated 1 to each fanpage. Posting content from diffirent user to each fanpage?

Reason I ask is becuase i had 1 group, and created another but it didnt raise the traffic to double (fanpages are equal in size). Im Posting on both groupo from same profile. The pages have their own domain/website.

Anyone know.....?

I have both situations: (1:1) and (5:1)
I didnt notice any difference, but I think it depends on more factors.

There shouldn't be difference at all. Good posts will get engagement and it will bring you higher reach, as the reach grows so do the engagement...
No of FB accs (Admins, Editors) can't make any difference.

Contents that will appeal to your targeted audience would increase user engagement. It doesn't really matter how many times you share the post on groups (which are spammed most of the time). If you share shit, you get shit engagement and slim tp no chance of getting traffic.
