There is a lesson every TikTok Shop seller learns the hard way: testing a product on paid traffic is expensive. An initial awareness campaign to validate a single new product costs, on average, between R$1,000 and R$2,000 a month in Brazil, with a CPM between R$10 and R$30 and a CPC between R$0.50 and R$3.00. Now multiply that by 3, 5, 10 different products until you find one that actually sells — and the "cost of discovering the right product" has already become an investment of several thousand reais, with no guarantee of return.

Vellum Lens exists precisely to cut out that most expensive step of the process.

WHAT CHANGES WHEN YOU ALREADY KNOW WHAT IS SELLING

Instead of putting a product live and hoping paid traffic validates whether it has demand, Vellum Lens shows, with real data updated daily, which products are already growing in sales within TikTok Shop, in which categories, at what growth speed and in which shops it is happening. In other words: the demand validation has already happened — for free, inside the platform itself — before you decide to spend the first real on ads.

This changes the campaign's ROI in two direct ways:

First, you stop paying to "discover". The entire media budget goes straight to scaling a product that already has a real demand signal, instead of being split across several blind tests. Second, the ad creative itself becomes easier to get right the first time, because you already know which product, which price range and which category are performing — which reduces the number of ad variations the agency has to test before finding the winning creative.

LESS GUESSING, MORE DATA

A media buyer works better when they receive a validated product than when they receive an "I think this will sell". That is why the most efficient combination for anyone selling on TikTok Shop is: use Vellum Lens to choose the product and category with a real growth signal, and then take that already-validated product to a specialized paid traffic agency — such as WBR Tráfego Pago (wbrtrafegopago.com) — to structure the scaling campaign.

In practice, this means getting out of the "test, spend, it does not convert, test another product, spend again" cycle and going straight into the "scale what I already know works" phase. It is the difference between paying to discover and paying to grow.

THOSE WHO ALREADY USE PAID TRAFFIC FEEL IT FIRST

If you already run paid traffic campaigns today and feel the cost per sale is too high, it is worth stopping to ask: does the product being advertised have real demand data behind it, or was it chosen on guesswork? Most of the time, the problem is not in the creative or the targeting — it is in the product choice back at the start. And that is exactly the step Vellum Lens solves before a single real is invested in ads.
