A social media content audit takes 20 minutes if you do one thing: compare every post with your own median, then sort the results into keep, fix or retire. You do not need to go back through everything you have ever posted. Thirty posts and a timer are enough.
TLDR: Pull your last 30 posts, find the median, then group the posts by format and topic and mark each group keep, fix or retire. Posts below 0.8x your median are your low performers. In Mydrop's data, carousels ran 10% above an account's typical post, so that is a good first thing to look for.
Minute by minute
| Minutes | Step | What you produce |
|---|---|---|
| 0 to 3 | Pull the last 30 posts with reach, engagement, format, date and hour | One table |
| 3 to 6 | Find your median reach and engagement rate | Your baseline |
| 6 to 10 | Mark each post as above 1.1x, near 1.0x or below 0.8x | A colour-coded list |
| 10 to 15 | Group by format and by topic, and note which groups cluster high or low | Two or three patterns |
| 15 to 18 | Label each group keep, fix or retire | A decision per group |
| 18 to 20 | Write down next month's changes | A short action list |
Step 1: use your own median as the yardstick
Measuring yourself against someone else's benchmark tells you very little. Use your account's median instead: sort your 30 posts by reach and take the one in the middle. A post at 0.9x the median is just noise. A post at 0.6x is a genuine miss.
To get a feel for the normal range, here is Mydrop's September 2026 data: the median Instagram post earned a 3.1% engagement rate, and the middle half of posts landed between 1.1% and 6.7%. If your numbers fall inside that range, your account is typical.
Step 2: look for patterns, not single posts
One bad post is bad luck. Three bad posts with something in common is a finding. Check these in order:
- Format. Which formats sit below 0.8x? In our data, carousels ran 10% above an account's typical post, photos and videos sat right at the median, and a link in the caption cost 7%.
- Time. Do your weak posts cluster late at night? Posts published between midnight and 6 am local time ran 17% below the median across platforms.
- Topic. Does one topic keep landing low, even in different formats?
- Caption. In the same data, captions under 80 characters ran 9% below the median. Longer ones were within 3% of it, so past that point length made no real difference.
Step 3: sort each group into keep, fix or retire
Here is the rule for low performing content:
| Result | What it means | Action |
|---|---|---|
| Group above 1.1x median | Working | Keep it and add one slot a month |
| Group between 0.8x and 1.1x | Average | Fix: change one thing (format, hour, hook) and test again |
| Group below 0.8x after 3 or more posts | Not working | Retire it, or change it once and check again |
When you fix something, change one thing at a time. Otherwise you will never know what worked.
Step 4: write down the changes
Finish every audit with a short list of changes for the next four weeks. Keep it to three:
- One group to expand.
- One group to change.
- One group to stop.
Put the changes straight into your calendar, so they happen by default rather than because you remembered. In Mydrop's calendar you can set them up as recurring slots for each account.
What to skip
Not everything belongs in a 20-minute audit. Save these for a longer review:
- Old posts from before your strategy changed.
- Paid posts, which have their own metrics.
- Competitor comparisons, which take longer and often tell you less than your own data.
Make the audit faster each month
Most of the 20 minutes goes on pulling and sorting numbers. Mydrop's performance view shows each post against that account's own median, so steps 1 and 2 shrink to a few minutes, and scheduled reports can send you the summary every month. If you manage several accounts, that is the difference between losing an afternoon and having a coffee break.
If you want an audit built around AI answers and search, see the AI-ready content audit. And if the audit shows your reach is stuck, our 30-day recovery plan turns what you found into weekly steps.
Next step: set a 20-minute timer, pull your last 30 posts and find your median. You can start free with Mydrop and connect your accounts to see every post against its own baseline.
