How to analyse your Instagram competitors: method, metrics and limits

Competitive analysis on Instagram usually ends in a folder of screenshots nobody opens again. Not because it was done badly, but because the last step is missing: turning what you saw into a decision. This is the method we use.

Step 1: define the category, not the sector

The most common mistake is picking business competitors. For content, your competition is the accounts competing for the same attention, which is not always the same thing.

If you sell technical running shoes, your content competitor may be a trail-running creator with 40,000 followers, not the other shoe brand. A useful set is 5 to 12 accounts: fewer does not give a pattern, more becomes unmanageable.

Step 2: normalise before you compare

Comparing an account with 500,000 followers to one with 8,000 in absolute numbers says nothing. Each account should be measured against its own history: which post breaks its average, not which one has more likes in absolute terms.

That frame change is what turns a data table into a reading. The interesting part is not that the large account has more reach: it is that one of its pieces did three times what it normally does, because that is where there is something to learn.

Step 3: measure what is actually public

What you can compare with real data:

• Frequency and cadence — how much each account publishes and whether it holds or goes in bursts.
• Format mix — Reels, carousels, single image, and how the mix has changed.
• Themes — what the category talks about and which territories are already taken.
• Visible engagement — likes and comments, always relative to the account itself.
• Standout posts — the pieces that break the average, and what they share.
• Evolution — how the strategy has changed over the last six months.

And what you cannot know from someone else’s account, no matter what a tool shows you: reach, impressions, saves, shares and watch time. Instagram does not expose third-party data. If those numbers appear, they are estimates, and you should know that before you build a strategy on top.

Saying this out loud in front of a client is more credible than showing an invented number.

Step 4: look for the pattern, not the piece

This is where useful analysis splits from an inventory. Once you have the pieces that break each account’s average, the question is what they have in common.

• Do they open with a question, a strong claim or a data point?
• How long are the videos that work versus the ones that do not?
• Is there a person on camera or not?
• When does the brand appear?

That last point weighs more than it looks: retention changes noticeably depending on when the brand element comes in. It is exactly the kind of pattern that only appears when you analyse the first seconds systematically instead of watching videos one by one.

Step 5: turn the pattern into a gap

The deliverable is not “this is what the competition does”. It is “this is what we are going to do”. Three questions close the analysis:

1. Which territory is saturated? If all twelve accounts do the same thing, that space no longer differentiates.
2. Which territory is free and fits us? A gap that does not suit you is not an opportunity.
3. Which format performs in the category and we are not using?

With those three answers you have a content decision you can defend in a meeting without falling back on “I think”.

How often to repeat it

A full benchmark each quarter and a light review each month is usually the right balance. More often confuses noise with signal; less often and you arrive late to format changes, which move fast on Instagram.
