The SellThisNext checker ranking six product ideas, each with a score from 0 to 100 and a colored score breakdown Few reviews, lots of small sellers.
This is the one to test first. Huge demand, but big sellers
own most of the clicks.
The free checker, run on its demo data.

Most bad Amazon products looked good on paper.

You see a listing with thousands of reviews and think: people buy this. They do, from the three sellers who already own the page.

You find a keyword with huge search volume. Then you learn the top five listings take most of the clicks.

You order 500 units because that's the supplier's minimum. Three months later, most of them are still sitting in storage.

The tools that would have warned you cost $49 to $279 a month, before you've sold a thing.

Amazon already shows you the real numbers in Opportunity Explorer, for free. They're just hard to read. SellThisNext reads them for you.

The surpriseBike seats scored 48. Shoppers search for them all the time, but a few big sellers take most of the clicks. Popular is not the same as possible.

The winnerE-bike displays scored 71. Fewer shoppers, but the clicks are spread across many small sellers with few reviews. That's a market a new listing can get into.

Detail view for drawer dividers: 65,205 shopper clicks a month, median 1,509 reviews, easy entry 5 out of 30, and keywords marked very hard 65,000 clicks a month, but the typical
listing has 1,500 reviews. Hard to break in.

What you see for every idea

A score from 0 to 100 and a plain verdict: sell this, maybe, or skip.

Why it scored that way. How many shoppers there are, how many clicks go to listings with under 500 reviews, whether the top 5 take everything, and whether newer listings are winning.

The keywords to use, with monthly searches, how hard each one is to rank for, and roughly how many units you'd need to sell to launch.

Real 30-day demand, including searches where shoppers look but rarely buy. Sometimes that's a gap you can fill.

Real data, read by a real person

Hi, I'm Majid. I research Amazon products using Amazon's own data: what shoppers search for, what they click and what they buy. I built SellThisNext's scoring method on the free Opportunity Explorer downloads, so you can decide with numbers instead of guesses or an expensive monthly tool.

My background is in engineering and data analysis. When you order an Expert Review, I read your results myself and tell you which ideas I'd pick, and why.

Questions

Do I need an Amazon seller account?

For the reports, yes: the data comes from Product Opportunity Explorer, which is free inside Seller Central. No account yet? Choose Guided Setup and we'll walk you through creating one on a video call, then do the research together.

How does Guided Setup work?

We meet on a video call and share your screen. You enter your own details (Amazon requires the account owner to register with their own ID, bank and tax information), and we explain every step. Then we download your product research data together and send your report. We never ask for or keep your password.

Do you need my password or login?

Never. You download the files yourself and send them to us. Please don't send us your login details.

How long does it take?

The free checker gives results instantly. Expert reports arrive within 2 business days after we receive your files. Either way, you spend about 5 minutes per product idea downloading the files with our guide.

Are the numbers exact?

Search counts and purchases come from Amazon's own data. Scores, keyword difficulty and launch units are our estimates based on that data. They're for comparing ideas, not a sales guarantee.

What if my files are wrong or missing?

We'll tell you exactly what to fix. If we can't build your report from the files, you get a full refund.

What happens to my data?

We use your files only for your report and delete them within 7 days after delivery. Files you check in the free checker never leave your computer. See our privacy policy.

Are you part of Amazon?

No. SellThisNext is an independent service for Amazon sellers and is not affiliated with or endorsed by Amazon.
