What KPIs (key performance indicators) to measure on Instagram.
What KPIs should you measure on Instagram? (And what they actually tell you)
Creating social content as a business without regularly checking your analytics is a bit like travelling on the tube without looking at the tube map... you might end up somewhere interesting, but you've got no real idea how you got there or whether it was the most efficient route. 🙈
Instagram insights are genuinely useful- but only if you know what you're actually looking at, and more importantly, what each metric is telling you about your business. Because not all numbers are equal, and the ones worth paying attention to depend entirely on what you're trying to achieve in your business.
This post walks through the key metrics available in your instagram analytics, what they actually mean, and how to use them to make better decisions about your content.
Before you look at any numbers, know your goal.
This is the part most instagram analytics guides skip, and it's probably the most important bit…
A metric only means something in the context of what you're trying to do.
What I mean is, if your current goal is brand awareness, reach is the number that matters most to you right now. If you're trying to move people from instagram into your wider world- your email list, your website, your services- then website clicks and profile visits tell a more useful story, or if you're building a community of people who genuinely connect with your brand, engagement and impressions are your most revealing signal.
Knowing your goal first means you're not just staring at a dashboard of numbers wondering what to do with them... you're looking for specific answers to specific questions.
Reach.
Reach measures the number of individual accounts that have seen your content- so it's your core brand awareness metric. Instagram breaks this down further into new accounts reached versus existing followers, which is genuinely useful for understanding which types of content are doing which job.
Currently, reels tend to be strongest for reaching new eyeballs, stories for connecting with existing followers, and carousels/images sit somewhere in between... though this shifts over time and your own account data will always be more reliable than general advice. 🙂
What's working on someone else's account in your industry might look completely different on yours, so use the broader patterns as a starting point and then check what your own insights are actually showing you.
Impressions.
Impressions measure the total number of times your content has been seen, including multiple views by the same person. So if someone scrolls past your carousel, sees the first image, keeps going, and then sees it again later and stops to read it- that's two impressions from one account, or if someone watches your reel 3 times, that would be 1 reach, but 3 impressions.
On its own, impressions as a metric is interesting but not especially actionable... it's most useful when you combine it with reach, because the gap between the two tells you something about how often people are coming back to your content. A high impressions-to-reach ratio can indicate that people are rewatching or revisiting, which is generally a positive signal.
Profile visits.
Profile visits tell you how many people landed on your grid- whether they came from a piece of content, a search, a tag, or somewhere else entirely. It's a helpful indicator of how well your content is sparking enough curiosity to make someone want to know more about you, or whether your existing followers are searching for your profile to come and see your latest content.
Looking at profile visits alongside follower growth gives you a sense of how well your profile is converting that curiosity into actual follows. A lot of profile visits but relatively few new followers can sometimes suggest the profile itself needs attention- the bio, the grid, the highlights- though it can also simply mean a proportion of visitors were already following you, so treat it as a guide rather than a verdict.
Website clicks.
Website clicks measure how many people have clicked the link in your bio, and for most businesses, this is one of the more commercially meaningful metrics in your instagram analytics... because it's the moment someone moves from passive audience member to actively seeking you out beyond the platform.
Getting people off instagram and into your wider content- your website, your newsletter, or your resources for example- is how you take the relationships you're building on the platform somewhere they can actually develop. A lot of website clicks but low conversion on the other end (enquiries, sign-ups, sales) is worth paying attention to too, because it might indicate a disconnect between the audience instagram is sending you and the audience your offer is actually for.
Engagement and accounts engaged.
Reach tells you how many people saw your content, but accounts engaged tells you how many of them actually did something with it- a like, a comment, a save, a share, a reply to a story. These are two very different things.
Instagram's current algorithm places significant weight on shares and saves in particular... a share means someone found your content valuable enough to send to someone else or add to their own story, and a save means they wanted to come back to it. Both are strong signals that your content is being received well, and both tend to correlate with content being shown to more people.
Combining your accounts engaged figure with your reach gives you an engagement rate, which is a more useful comparison tool than raw numbers- especially if your account is growing, because what counts as 'good' engagement shifts as your audience size changes.

Watch time and video performance.
This one has become increasingly important as instagram has leaned further into video. For reels and longer video content, instagram now surfaces watch time as a key signal- how long people are actually watching, and whether they're watching through to the end or dropping off partway through.
A high average watch time suggests your content is holding attention, which instagram takes as a signal of quality and rewards with wider distribution. But as with all metrics, it's worth looking at this in context... a longer, more informative video that gets strong watch time from a smaller, highly engaged audience might be doing a more valuable job for your business than a short reel with huge reach but minimal meaningful engagement.
One thing I have to say though- it can be tempting to game watch time with a short looping video (a six second clip that plays on repeat, with all the actual information buried in the caption)... and technically, yes, that would boost your watch time metric. But the experience for the person watching is pretty poor, and over time that kind of friction is the thing that gradually erodes the trust and goodwill you've been building with your audience. (I personally hate videos like that 😅) A metric that looks good on a dashboard but leaves your viewer feeling a bit cheated isn't really working for your business, whatever the numbers say.
Follower count.
The one metric everyone wishes they cared less about, and yet here we are. 😆
Follower growth does matter- to a point- reaching new people and growing your audience is a legitimate business goal, and a declining follower count is worth understanding rather than ignoring.
But…
it's most useful as a long-term trend rather than a day-to-day obsession... tracking a simple monthly percentage growth figure means you can spot patterns and understand what's normal for your account, without the distraction of watching individual follows and unfollows.
The number to keep an eye on alongside follower count is the quality of who's following you- are the people arriving actually your ideal audience? A smaller, well-matched following tends to produce better engagement, better website click-through, and better commercial outcomes than a large audience that was never quite the right fit.
At the end of the day, a large following of followers is just not as good as a small following if buyers.
Using your instagram analytics well.
The most useful thing you can do with all of this is build a simple monthly habit of recording the metrics that match your current goals, noting what content performed well and what didn't, and looking for patterns over time rather than reacting to individual posts.
Instagram insights are there to inform your content decisions, not to make you feel good or bad about what you posted last Tuesday... used well, they're one of the clearest signals you have about whether your content is actually working- and what to do differently if it isn't.
