Instagram reach problem

Hello, I have a question. I grow three accounts with MassPlanner and I do not understand what I am doing wrong.

I took the accounts from 0. Two of them have 3500 followers and the other one has 1500 followers. The images that were posted from the beginning (since the accounts were created) have a lot of likes. However, today I posted pictures on all three to test the reach. No picture got as many likes as the previous photos on all three accounts, but why? For example, one account has 3500 followers and 1100 likes at the first picture posted but the picture posted today only got 34 likes!!! Why?!

good evening,

first of all you have to make an analyze from where do u have the visitors, after that double check the tags and at last of course the quality of picture is really important

lets discuss all 3 options .

1. wrong time for posting, there are time differences from different countries and there is possibility that ur audience is sleeping at this time

2. no tags or too many tags , there is also an option , it could make some trouble for you

3. image quality is one of the most important thing on instagram , each of posts must be better than the old one

let me know how your business will go on, its interesting for me too

The photos are fine but I do not use tags. I want my followers to like the photos, at least 10% from the followers.
