Bestseller Gap Scanner
helio / ecommerce-bestsellersPoint it at a category and a marketplace. Your AI teammate scans the real bestseller list every week, compares it to what you stock, and hands back a ranked list of the products you're missing.
Scan Amazon's top 100 bestsellers in Home & Kitchen every Monday, compare the list to my current inventory, and send me a ranked report of the trending products I don't yet carry. Ask me what you need before you start.
Swap in your category and marketplace. It runs the scan on a weekly schedule after.
What is Bestseller Gap Scanner?
It scans a category's real marketplace bestseller ranking, matches every entry against your current inventory, and ranks the gaps by momentum. It won't add anything to your catalog; it surfaces the missing products and leaves the call on what to stock to you.
What it does
Any chatbot lists trending products once. Helio runs the scan as a standing job — from your context, kept current, delivered to you.
| Owns the whole job | It reads the real bestseller list, matches each product against your inventory, and writes the ranked gap report. |
| Runs again without starting over | The scan runs every week on a schedule in the same format, so gaps show up as they emerge. |
| Works from your context | It reads the marketplace and category you sell in and checks against your current inventory list. |
| Keeps itself current | It tracks each product's ranking week over week, so a climbing item is flagged before it tops the chart. |
| Lands where you work | The ranked gap report arrives in Slack, Lark, or email. You don't open Helio to read it. |
Three things it gets right
Reads the real bestseller list
It pulls the marketplace's live top-sellers ranking, so a rising product shows up whether or not it's ever appeared in your own sales.
Ranks gaps by momentum
A product climbing fast outranks one sitting still, so the report leads with what's about to matter, not just what's present.
Flags a product before it peaks
Week-over-week ranking shifts surface a climber early, so you can source it while it's still an opening.
What Bestseller Gap Scanner connects to.
Questions
- Where does the bestseller data come from?
- It reads the marketplace's own live bestseller ranking through the browser, not your sales history — so it catches products you've never carried and would never see in your own numbers.
- How does it rank the gaps?
- It weighs each missing product by how fast it's climbing, not just whether it's on the list, so a fast riser lands above a steady seller you happen not to stock.
- How does it know what I already carry?
- You connect your current inventory list. It matches each bestseller against that list and reports only the products you don't yet stock.
- Can it watch more than one category?
- Yes — give it each category and marketplace you sell in, and it runs a separate weekly scan for each and reports the gaps per category.
