How to Analyse a Competitor's Instagram Strategy (Step-by-Step)

Most brands look at a competitor's Instagram the same way they look at someone else's apartment — they notice the surface level stuff and move on. Nice aesthetic. Good follower count. They seem to be doing well.

What they miss is everything useful: which content is actually driving engagement, how often they're posting, what their best-performing format is, whether their growth is real, and what gaps they're leaving open.

This is a walkthrough for doing it properly.

Step 1: Identify Which Competitors Actually Matter on Instagram

Not every competitor deserves your analysis time. Start by identifying two or three accounts that are either:

• Directly competitive — same product, same target audience, fighting for the same customers
• Aspirationally ahead of you — in your category but with a larger, engaged following you want to understand
• Winning on a format you're not using — brands in adjacent spaces doing something that could translate to your niche

Avoid wasting analysis time on accounts that are either completely unrelated or so different in scale that comparison isn't useful.

Step 2: Run the Account Through an Audit Tool

Before you manually scroll through their feed for 45 minutes, use Rivalgram to pull a structured breakdown of any public Instagram account. Enter the handle and you get: engagement rate (broken down by post type), posting frequency and cadence, follower growth signals, and which posts drove the most engagement.

This gives you the skeleton. You're not guessing what's working — you're looking at data.

The audit identifies their highest-engagement content — both by post type (Reels vs static vs carousel) and by topic cluster. This tells you in 60 seconds what an hour of manual scrolling might not.

Step 3: Analyse Posting Frequency and Cadence

How often are they posting, and when?

Frequency tells you how much they're investing in content. A brand posting 6 times a week has a serious content operation. A brand posting twice a week is either resource-constrained or being highly selective.

But frequency alone isn't the insight. The insight is what happens to engagement as they post more or less. Some accounts post daily and maintain consistent ER — their audience is hungry for content. Others see ER drop sharply when they increase volume, signaling their audience prefers quality over quantity.

Also look at the day-of-week and time-of-day patterns in their high-performing posts. This is a proxy for when their audience is most active — and if you're targeting the same demographic, that's your window too.

Step 4: Break Down Their Content by Format

Manually categorize their last 30–40 posts:

• Reels — short video, typically organic reach driver
• Carousels — multi-image, typically high save rate and educational content
• Static posts — single image, usually brand aesthetic or announcement

Which format dominates their top performers? Which format do they post most often vs. which format performs best? There's often a gap — brands posting mostly static when their Reels are doing 3x the engagement, for example.

That gap is your opportunity. If a competitor is clearly underinvested in a format that their own audience responds to, and you can execute that format well, you have an opening.

Step 5: Reverse-Engineer Their Content Strategy by Topic

Look at the themes across their highest-engagement posts. Group them loosely:

• Educational / how-to content
• Product-forward / promotional
• User-generated content and testimonials
• Culture and behind-the-scenes
• Trend participation (seasonal, viral formats)

Which themes get the most traction? A D2C food brand might see their recipe content outperform product posts by 3x. A fashion label might find that behind-the-scenes manufacturing content gets better engagement than lookbooks.

This tells you what their audience actually wants from them — which is often different from what the brand thinks it should post.

Step 6: Look for What They're Not Doing

This is where competitive analysis pays off beyond imitation.

Every brand has blind spots. Maybe they've built a strong Reels presence but never post carousels, even though educational content would fit their niche. Maybe they're strong on aspirational lifestyle content but haven't touched creator collabs or UGC.

The goal isn't to copy their strategy. It's to find the version of their strategy that they're not executing, and own it before they figure it out.

Step 7: Track Follower Growth Signals

Follower count is vanity. Follower growth rate is more interesting. And the quality of follower growth is what actually matters.

A competitor who gained 15,000 followers in a month might have run a successful Reel that hit the explore page, done a major collab, run a giveaway with low-intent followers, or bought followers. These scenarios have completely different implications for their actual market position.

What to Do With What You Find

Competitive analysis is only useful if it changes something you're doing. After you've run through this:

1. Identify one format gap — a format the competitor underutilizes that their audience responds to — and commit to owning it 2. Identify two or three content themes where their engagement is strongest and consider how to do a version of that better, with your brand's voice 3. Note their posting cadence and use it as a floor, not a ceiling 4. Set a 30-day benchmark — audit their account again in a month to see if the gap you identified is being closed or is still open

Instagram competitive analysis isn't a one-time exercise. The best brands do a light version of this quarterly and a deep dive every six months.
