Identify 3–5 core competitors
A core competitor on Instagram is an account in your niche with an active posting cadence of 3–5x per week and engagement above the niche median. Start with accounts your audience already follows — check who your followers engage with using Instagram's 'Suggested' feature, or search your top-performing hashtags and note which accounts appear repeatedly.
- Follower range: 5K–500K performs best for signal extraction — large enough to have real engagement data, small enough that their tactics are replicable
- Minimum 3 accounts: one account's style may be an outlier; 3 accounts let you spot patterns
- Active in the last 30 days: dormant accounts produce stale signal
- Same content format scope: if you post carousels and Reels, track competitors who do the same
