How to Make eBay's Algorithm Work for You (So You Actually Make Sales)

Let’s talk about how to actually make sales on eBay. It’s not about luck. It’s about understanding the system and playing by the rules in a smart way.

eBay uses a special algorithm called Cassini. Think of it like a robot that decides which products show up for buyers. If we know how Cassini thinks, we can make it work for us.

Here’s what you need to know: eBay gives new listings a “boost.” When you list something, Cassini shows it to buyers right away. But that boost only lasts a little while, unless you get a sale.

If your item sells, it gets boosted again. Another sale? Boosted even more. That’s why your goal should be simple: get a sale fast. If you do, your listing stays near the top. If you don’t, it drops down to page 10... 20... or 60, where no one will ever find it.

Here’s the trick: list daily, and try to get that first sale quickly. It keeps the snowball rolling. Even if your listing drops to the bottom, a sale can shoot it right back up to the top. One sale can change everything.

Why does eBay work this way? Because they want to find what’s selling best. They make money from seller fees, so it’s in their interest to show buyers the items that sell fast. Cassini is always watching.

This means you don’t need the “perfect” price. You just need a price that’s in the buyer’s budget. Convenience and fast delivery matter more than being the cheapest.

And that’s where Infinity helps. We help you list faster, price smarter, and stay consistent, so you always have fresh listings getting those boosts.

The best sellers on eBay aren’t the luckiest. They’re the ones who understand the rules and use tools like Infinity to win.
