⚠️The cost of doing nothing

Every day without Labelizer is money walking out the door.

Manual feeds and a black-box algorithm quietly drain your profit. If any of this sounds familiar, you’re already bleeding budget, you just can’t see it yet.

✕
💸
Budget bleeds on losers
Spend keeps flowing to products that lose money on every single order.
✕
🎰
Google calls the shots
Performance Max decides what to show, and it rarely favours your highest-margin products.
✕
🧮
Endless manual labeling
Tagging products by hand in spreadsheets eats hours of your week, every week.
✕
📦
Out-of-stock ad spend
Sold-out sizes and variants keep burning budget you will never get back.
✕
🐌
Bestsellers throttled
Your proven winners get capped while weak products quietly coast along.
✕
⏳
Always reacting late
By the time a report reveals the problem, the wasted spend is already gone.

Take back control of PMax

Reaktion Labelizer puts your winners back in control.

In Performance Max, Google’s algorithm decides what to show, and your most profitable products don’t always get the visibility they deserve. Reaktion Labelizer fixes that: it scores every product and labels your winners for more budget while pulling the margin-drainers, automatically and in near real time.

✓ Your most profitable products always get priority and budget
✓ Stop wasting spend on sold-out sizes and low-converting variants
✓ Updates in near real time as performance and stock change
