A content gap is a topic your audience cares about that your feed does not cover well, or covers in only one format. Finding them used to mean a long spreadsheet and a lot of guessing. With AI doing the sorting, the real work is giving it your own data and deciding what to do with what it finds.
TLDR: Export your last 90 days of posts, group them by topic and format, compare against what your audience asks and what competitors cover, then ask AI to list the gaps. Turn the top three into planned posts.
Step 1: export what you published and sort it by topic
Start with facts about your own feed. Export 90 days of posts with date, caption, format and engagement rate. Ask AI to tag each post with one topic and one format.
You get a simple map: how many posts per topic, how many per format. Most teams are surprised. A topic you think you cover weekly often turns out to be 2 posts out of 40.
Step 2: collect what your audience is actually asking
Gaps are only gaps if someone wants the content. Gather the evidence from places you already own:
- Comments and DMs that ask a question.
- Search terms people use to find your site.
- Customer support questions that repeat.
- Replies to your posts that start with "Can you do one on".
Paste the raw list into your AI tool and ask it to cluster the questions into topics. Remove anything you would never answer.
Step 3: compare your map to the audience's questions
Put the two lists side by side. A table keeps it plain.
| Topic | Posts in 90 days | Audience questions | Gap? |
|---|---|---|---|
| Pricing and how it works | 1 | 14 | Large |
| Behind the scenes | 12 | 2 | Over-covered |
| How-to tutorials | 5 | 9 | Moderate |
| Customer stories | 0 | 4 | Missing |
This is an example layout, not our data. The pattern to look for is a topic with many questions and few posts.
Step 4: ask AI to find the gaps and give reasons
Give the AI both lists and ask for: topics with high demand and low coverage, formats you never use for a topic that suits them, and questions that could be answered in one post. Ask it to give a one-line reason for each gap so you can judge it.
AI is good at the clustering and the reading. It is not good at knowing your business, so check every gap against what you actually sell. Drop any gap you do not want to own.
Step 5: turn the top three into planned posts
Do not try to close every gap. Pick three: the ones with the most audience demand that fit your offer. For each, write a post brief with the question it answers, the format and the target date.
Mydrop's AI post ideas and bulk creation turn a gap list into a first set of drafts, and the content calendar shows the gap on the grid, so the missing topic is visible as an empty week. See AI social media content and the social media calendar.
Do not over-read engagement when ranking gaps
A topic with low engagement is not automatically a topic to avoid. It may have been posted once, badly. Compare against your account's normal level: in Mydrop's data, the middle half of Instagram posts ran between 1.1% and 6.7%, so a topic with two posts at 2% has not been proven weak. Give a topic three attempts in different formats before you drop it.
Repeat the check every quarter
Gaps change as your product and audience change. Put the five steps in your calendar once a quarter and compare to last time. If the "customer stories" row went from missing to covered, the process works.
