Here is the shortcut nobody admits to using: your competitors have already spent the time and money finding products that sell. Every winning product in their catalogue is the survivor of dozens of tests you didn't have to run. Finding products from scratch is slow; reading which products are already working for the seller next to you is fast — and their TikTok comment sections show you exactly that.
Most competitor research stops at surface metrics: follower counts, posting frequency, which videos got views. None of that tells you what's selling. The comments do. This is how to read a competitor's comment sections at scale to see which products are really winning for them, and how to use the gaps to beat them on the rest.
Views show what they post. Comments show what sells.
A competitor's most-viewed video is not necessarily their best-selling product, and the product they pin to the top is often the one with the fattest margin, not the most demand. The honest signal is in the comments: the products people are begging to buy reveal themselves through a flood of "where can I get this" replies, no matter how the competitor ranks them. Read the comments and you see their catalogue the way their customers do — sorted by real demand.
Step 1: Pick the right competitors
Don't study the giant brands — study the sellers one or two steps ahead of you, moving the kind of products you could realistically source and sell. Build a short list of three to five whose product videos consistently get traction in your niche. These are the ones whose winners are within your reach.
Step 2: Pull every product video's comments into one place
To compare a competitor's products against each other, you need all their comment data side by side. Export the comment sections of their product videos into one spreadsheet — and if you're researching several competitors at once, the bulk export workflow pulls every creator into a single file. Now you can rank their whole catalogue, not just react to one clip.
Step 3: Rank their products by buying intent
For each of the competitor's product videos, count the purchase-intent comments — "where can I buy this", "link?", "need this", "just ordered", "restock?". Compute intent per video and sort. The products at the top are their genuine winners — the ones their audience is actively trying to give them money for. This is the single most useful output of the whole exercise: a demand-ranked view of a competitor's catalogue, built from their own customers' words. For thousands of comments, AI analysis does the counting automatically.
Step 4: Harvest the objections they haven't fixed
A competitor selling a product well is not the end of the story — it's the start of yours. The objections in their comments are the conversion blockers they've left on the table, and each one is a way to win the same customer:
- "Too expensive" → undercut with a leaner version or reframe value with a bundle.
- "Looks cheap / does it work" → out-prove them with demos, reviews, and a guarantee.
- "Wish it came in…" → stock the variant they don't offer.
- "Shipping took three weeks" → make fast fulfilment your headline.
You're not copying their product — you're selling the better version their own customers described.
Step 5: Find the demand they're ignoring
Scan for repeated questions and requests the competitor never answered or stocked: "do you have one for…", "can it also…", "what about a bigger size". Unmet, repeated demand sitting in a competitor's own comments is the cleanest opportunity there is — proven want they're leaving unserved. Those threads are a product roadmap written by the market.
Step 6: Check the audience is one you can serve
Before you act, make sure the demand is reachable. Run audience analysis on the competitor's most-commented videos to estimate the age, gender, and country of their buyers. If their winners sell to a region you can't ship to, the intelligence is interesting but not actionable for you. Confirm the overlap, then move.
Common mistakes in competitor product research
- Studying the wrong competitors. The biggest brand's winners may be unsourceable for you. Study sellers in your reach.
- Trusting views over comments. Views show reach; comments show demand. Rank by intent.
- Copying the product, ignoring the objections. The objections are the whole point — they're how you beat the incumbent instead of cloning them.
- Reading the top comments only. The unmet-demand gold is in the long tail. Export everything.
The bottom line
Your competitors did the expensive work of finding products that sell — their comment sections hand you the results for free, ranked by real demand, complete with the objections you need to beat them. Export a competitor's comments and let their customers tell you what to sell and how to win them.
