To turn Reddit threads into ad copy, find the threads where buyers argue about your category, sort the replies into the proof they trust, the claims they mock and the words they use, and write each ad to answer the strongest objection in those words. buzzabout is the tool built for this voice-of-customer job: it collects Reddit posts with their comments, groups them into themes with counts, and links every finding to the thread it came from.
Reddit is where buyers fact-check ads in public. That makes it the best place to learn which of your claims will land and which will get laughed at. Below is the method, then a worked example: 380 comments from five fresh dog food threads, turned into three ads.
Why use Reddit for voice-of-customer ad copy?#
Because Reddit is where people ask each other whether an ad is lying. One r/dogs thread put it in the title:
"Wife is getting suckered into doog food ads. Is there any scientific facts?"
A post on r/dogs, 261 comments
The replies to that post are a free copy test. They tell a fresh dog food brand which claims fail, what proof would work, and what buyers pay. An ad library cannot tell you any of that. It shows what brands said, not how buyers took it.
How do you turn a Reddit thread into ad copy?#
Five steps. Each works with any tool. buzzabout removes the slow ones.
- Find the threads where buyers argue. Search your category with "worth it", "vs", "anyone tried", "scam" and "ads". Skip threads with a handful of replies. In buzzabout, one plain-English question collects the relevant posts across Reddit and six other platforms.
- Read the replies, not just the post. The post asks. The replies answer, and the votes rank the answers. By hand, you open each thread and copy what matters. buzzabout collects the comments with every post.
- Tag every reply. Four tags cover most of it: trusted proof, mocked claim, objection, and exact phrase worth stealing.
- Count the tags. A claim one person mocks is noise. A claim twenty people mock is a rule. buzzabout groups the questions and objections in the comments into themes and shows how often each one comes up.
- Write the ad from the top of the count. Headline from the top objection, body from the trusted proof, words from the exact phrases. Then cut every claim the threads mocked.
Example: 380 comments on fresh dog food, three ads#
We read 380 comments across five threads in r/dogs and r/DogFood about fresh and premium dog food. Here is what they talked about:
A comment can sit in more than one theme. Three findings matter for copy.
Finding 1: The room trusts research, not adjectives#
More than a quarter of the comments mentioned research, feeding trials or a standard. Two of the five most upvoted replies to the "suckered" thread said it in a few words:
"WSAVA approved foods. The rest is marketing BS."
A reply in the r/dogs thread, 135 points
"Just buy from the brands that follow WSAVA guidelines
The rest lack long term peer reviewed studies"
A reply in the same thread, 107 points
WSAVA is "the World Small Animal Veterinary Association's guidelines," as one r/DogFood reply spelled it out. For this audience, the proof is who formulated the food and how it was tested. Those facts belong in the headline, not the fine print.
Finding 2: "Human grade" is a mocked claim#
"The whole concept of "human grade" is a scam."
A reply on r/dogs, 49 points
"I worked in the meat processing industry. “Human grade” is a scam."
A reply in the same thread, 16 points
Forty-three comments brought up marketing, ads or "human grade." If "human grade" is your lead claim, this room has already rejected it. Lead with something it can check.
Finding 3: Price is judged against kibble, per month#
Buyers do the math in public. One r/DogFood post says its fresh food is "very expensive (around $350 per month)." The "suckered" post says: "That's 4-1/2 pounds for $90!" And the second most upvoted reply argued that a cheap bag of kibble is already a step up:
"Here’s how I think about it. My dog, if left to his own devices, would eat literal garbage. He would dine on 3 day old road kill, and discarded pizza crusts, and fast food wrappers, and he would LOVE IT. Kirkland has to be miles ahead of his dream diet."
A reply in the r/dogs thread, 206 points
The objection is not "too expensive." It is "more than it is worth, compared with a bag of kibble."
The three ads#
Each ad answers one finding. The bracketed parts are proof slots: use them only if your product can back them.
| Ad | Headline | Body | Built from |
|---|---|---|---|
| Proof first | "Ask your vet about this one." | "[Formulated by a board-certified veterinary nutritionist]. [Feeding trial or standard it meets]. Bring the label to your next visit." | Research and vet themes (99 comments each) |
| No adjectives | "No 'human grade.' Just the numbers." | "[Fat, protein and calories per meal], printed on the box. Compare them with your current food." | Mocked claims (43 comments) |
| Price per day | "[Cost per day] for a [weight] dog." | "Picky eaters get [trial size] before you commit." | Price and picky eater themes (44 and 21 comments) |
The picky eater line comes from the threads too. One owner described a dog that "devours something for 10 days then looks at me like i served her cardboard" (r/DogFood).
What not to do: post in the thread#
The same threads show what happens when marketing slips into the replies. In the "suckered" thread, two replies posted weeks later read like endorsements, one with "shoutout to all those ads." In r/DogFood, someone testing a product idea answered critics in polished replies and got this back: "Are you using AI to respond?" Mine Reddit for words. Spend the budget on ads. Our guide to Reddit marketing covers the rules.
Where do you mine Reddit now that GummySearch is closing?#
GummySearch was the usual tool for this job. It stopped new signups on November 30, 2025, and on December 1, 2026 it shuts down and permanently deletes all user data (vendor site, November 2026). Its stated reason: it could not reach a commercial license agreement with Reddit's Data API.
If you used it, export your data before that date. Our GummySearch alternatives guide has the migration checklist. buzzabout covers the same Reddit research job, plus TikTok, Instagram, YouTube, X, LinkedIn and Facebook, so one platform's policy cannot end your research.

|---|---|---|---|---|
| Starts from | Threads you find | Text you paste | Ads: competitors' or your own | Your question, across Reddit and 6 more platforms |
| Reads the replies | One thread at a time | Only what you paste | No replies to read | Comments collected with every post |
| How many people say it | You tally | Only within your paste | Not shown | Named themes, with how often each comes up |

Ad libraries and ad analytics means Meta Ad Library and TikTok Creative Center (free), and Foreplay, Motion and Atria (paid plans). They show ads, not what buyers said about them (vendor sites, October and November 2026). For research tools of every kind, see our comparison hub.
Frequently asked questions#
Can I paste Reddit threads into ChatGPT instead? Yes, and it will summarize what you paste. It cannot tell you how often a theme comes up beyond your paste, and fetching threads itself is unreliable: our own web tool could not open reddit.com at all. Connect buzzabout over MCP and ChatGPT or Claude reads collected threads instead. More in our guide to customer research with ChatGPT or Claude.
Can I quote Reddit comments in my ads? Use their words to shape your copy. Do not publish a user's comment as a testimonial without permission.
How many threads do I need? Five busy threads gave us 380 comments and six clear themes. One thread gives you one crowd's opinion.
Which subreddits should I start with? The ones where buyers ask before they buy, such as r/DogFood for pet food or r/SkincareAddiction for skincare. Our Reddit social listening guide shows how to find them.
Does buzzabout write the copy? It finds the pains, objections and hooks your buyers respond to, and turns them into a brief with the posts behind it. Our guide to writing a creative brief from customer comments shows one. For TikTok, see how to turn TikTok comments into ad hooks.
What does it cost? Starting at $49 for your first month on Starter, then $98 a month. You can try it for free.
Let the replies write the first draft#
Your buyers have already argued about your category in public. The replies tell you which proof they trust, which claims they mock and what they pay. Read them before you write the next ad.
How we counted. Five public threads in r/dogs and r/DogFood, 380 comments after removing moderator bot replies. Themes were assigned with keyword rules, then checked by hand; a comment can sit in more than one theme. Reddit scores are as collected. Quotes are verbatim.
