Tracking Instagram post performance gives you the data to know what is actually working — not what feels like it is working. Post-level data reveals which content types drive follower growth, which drive engagement without follows, and which actively cause unfollows. Combined with our follower count tracker, this creates a complete content performance picture.

Connecting Post Performance to Follower Count
Instagram Insights shows "Follows" per post — how many new followers came directly from a specific post. Our Instagram Followers Tracker shows the daily follower count change. Together, they let you verify that high-performing posts (by saves and shares) are translating to actual follower gains the next day.
Building a Post Performance Tracking Spreadsheet
Create a simple spreadsheet with one row per post. Track these columns:
- Date published
- Format (Reel, carousel, single image, Story)
- Topic/category
- Caption hook (first line)
- Audio used (for Reels)
- Hashtags (yes/no and how many)
- Reach at 24h and 7 days
- Engagement rate: (likes + comments + saves) / reach
- Saves count (most important individual metric)
- Shares count
- Follows attributed to this post
- Notes: anything special about this post
Identifying Your Top Performing Content
After tracking 20-30 posts, patterns emerge. Sort your spreadsheet by each metric in turn: Which format gets the most reach? Which topic gets the most saves? Which hook drives the highest engagement rate? These patterns define your content formula — the specific combination of format, topic, and hook that your audience most consistently responds to.
💡The save rate (saves / reach) is the single most important metric for understanding content quality. Content with a high save rate is considered valuable enough to revisit. This signal drives algorithm distribution more than any other individual metric.
Posts That Cause Unfollows
Using our follower count tracker alongside your post calendar, you can identify posts that correlate with below-average or negative daily follower change. Days with unusual follower drops that follow a specific post type are worth investigating as churn drivers. See our follower loss tracker guide for the methodology.
For understanding the engagement side, see our engagement rate tracker guide. For overall tracking strategy, see our Instagram tracking tools page. Our unfollow tracker correlates post dates with follower loss. Start with our free online tracker.
