Marketplace — capability comparison

Beyond knowing who holds the Buy Box: understanding why you lose it

Most tools tell you whether you hold the Buy Box. Data Seekers tells you why you lost it, which seller took it, at what price, with what shipping cost per postcode — and gives you the levers to win it back.

What brands are living today

Three situations that keep recurring in marketplace teams

Real conversations with ecommerce and marketplace teams at brands selling on Amazon, eBay, Miravia, Mercado Libre and others.

The situation

Your tool alerts you when you lose the Buy Box. You know you lost it. But you do not know whether it was price, stock, seller rating, or a seller in another region who — once shipping is added to their price — turns out more competitive in certain postcodes. Without understanding the cause, every loss is firefighting, not a decision.

How we solve it

Exclusive

We monitor the reasons behind Buy Box loss — price, stock, seller conditions, shipping cost by postcode — so you can act on the real cause rather than just react to the alert.

The situation

Your product sells on eBay, Miravia, Mercado Libre and other marketplaces. On each one there are multiple sellers with their own product pages, their own prices and their own images. You have no visibility of what is happening on each one, or whether any of them is damaging your brand or your official price.

How we solve it

Exclusive

We access the full seller catalogue on any marketplace — price, stock, images and description — on Amazon, eBay, Miravia, Mercado Libre and anywhere else you operate.

The situation

You have unauthorised sellers offering your product on Amazon Spain. You spot them late, sometimes through an anomalous price alert. But you do not know whether it is a local distributor breaking terms or a seller from Amazon France arbitraging between markets and undercutting your official Spanish price.

How we solve it

Exclusive

We identify the origin of each seller: which marketplace they come from and which ones they are active in. A seller from Amazon France operating in Spain is a cross-market arbitrage problem, not a local distribution one — and the response is completely different.
