This might surprise some of you guys when I say that Posting several times a Day doesn't guarantee you a Bigger chunk of the Reward Pool.
Infact it clogs the Feed of the people who are following you.
So how many Posts should you make per Day?
Ideally you should make only one post per Day with all your research and substance in it.
That way your followers will get into it and it also increases your chances of getting more followers.
While one post is good you could also try posting Twice a Day if you have more Good content to shed upon.
But try to keep about a 12 hour Gap in between two posts.
I know how tempting it is for New users to post multiple times in a day so they could get some good amount of Upvotes on.
I know it because I used to do it too. I used to post about 10 times a Day which at the time seemed pretty good but later on I understood that Steemit works on Quality rather than Quantity.
I hope this post was a bit helpful to you Guys.
Try to keep a minimum of 12 hours Gap between two posts.
Steem on my Friends.
