Back when Instagram prioritized posts chronologically, the best way to get your content noticed by your ideal client was to post multiple times per day, everyday (Yikes).
Fortunately for all involved, Instagram has switched over to a “smart” algorithm, so posting everyday isn’t necessary (unless that’s your jam, you do you). These days, it prioritizes posts based on a number of factors, including who you interact with most frequently and whether or not your content is deemed “valuable.”
Your posting frequency and times will depend largely on,
1. If/when you are able to engage with your followers,
-I recommend engaging ten minutes before and ten minutes after you make your post.
-If you can only truly engage on Tuesdays and Thursdays at Noon, then you should only post on Tuesdays and Thursdays at Noon.
2. If you have content that fills at least one of the following criteria:
-It's Entertaining,
-It's Educational or Informative,
-It forges some kind of a connection
[These are the three main reasons your ideal customer is USING Instagram. Don’t post just for posting’s sake!]
All of that said,
I DO recommend showing up in your feed at least two times per week and showing up in your stories at least five times per week.
