You should probably know the difference between Impressions Vs. Reach
Impressions are the total number of people Instagram shows your content. On the other hand, Reach refers to the number of people who choose to see your content and engage with it through likes, comments, or shares.(Source: https://blog.hubspot.com/marketing/impressions-vs-reach)
In case you have no idea what I’m talking about, every business account on Instagram and Facebook (and others) has something called “Insights.”
Within the Insights section, you’ll see a category called “Reach” and one called “Impressions.”
I know, they sound like the same thing.
And to make things even more confusing, these terms can mean different things on different social media platforms.
For now, let’s focus on Instagram.
Reach is the number of unique users that interact with any of your posts, stories, including promoted posts, stories, or IGTV videos, at least once. Each user is counted once, even if they interacted in multiple ways. Reach isn’t just about your followers; Instagram showed your posts to various accounts that Instagram thinks have a common interest with your post. Commonality can be through pages they follow, hashtags searched, and the posts they comment and like.
Impressions: how many times your posts were on screen. This number includes the same account viewing your posts over and over again. This number is usually higher than the reach.
So, the burning question is: which one is more important, and does it matter?
If you’re running ads, you’re going to want to watch impressions. You pay to have your ad shown to accounts, so the number of impressions will matter.
If you’re looking for engagement and followers, you’re going to want to concentrate on reach. Reach demonstrates how well you’re interacting with your audience.
If your reach numbers are not increasing as you post more regularly, you’ll want to take a look at what hashtags (#) you’re using. Do some research on what hashtags the accounts you want to be like use.
