Product Value Adjustments: Bidding on Margin, Not Revenue (2026)
TL;DR: Product Value Adjustments (PVA), a pilot announced around Google Marketing Live 2026, lets you apply percentage multipliers to conversion values for specific items within Smart Bidding. In plain terms: you can finally tell Google that a 60% margin product is worth more to you than a 15% margin bestseller at the same price. Set up margin tiers with custom labels, apply sensible multipliers, and review monthly. Done right, this moves your account from revenue optimization to profit optimization.
The ROAS trap almost every store falls into
Target ROAS optimizes revenue against spend. It has no idea what your products cost you. So Smart Bidding does exactly what you asked: it pours budget into whatever converts revenue efficiently, which is usually your discounted bestsellers with the thinnest margins.
I see this pattern constantly in audits. A store runs at a healthy 700% ROAS and still struggles to make money, because 70% of the ad spend sits on products earning 12% margin while the 55% margin lines starve. The account is winning the game Google was told to play. It is just the wrong game.
What Product Value Adjustments actually do
PVA is a pilot feature that lets you apply percentage multipliers to the conversion values of specific items, directly inside Smart Bidding. If a product carries a strong margin, you can adjust its conversion value upward. If a product barely breaks even, you adjust it downward. Smart Bidding then optimizes toward the adjusted values.
The elegant part: your reported revenue does not change, and you do not have to rebuild your conversion tracking to send margin data. You are reweighting what "value" means to the bidding algorithm, item by item, so the machine finally chases the money you actually keep.
Practical setup: margin tiers and multiplier logic
Do not try to set a multiplier per SKU. Group products into margin tiers and keep the logic simple:
- Build 3 to 5 margin tiers with custom labels. For example: label "margin-high" for 50%+ margin, "margin-mid" for 25 to 50%, "margin-low" for under 25%.
- Anchor multipliers to your average margin. If your blended margin is 30%, a 60% margin tier gets roughly a +100% adjustment (2x value) and a 15% margin tier gets roughly a -50% adjustment (0.5x value).
- Sanity-check with numbers. A 100 euro sale at 60% margin earns you 60 euros; at 15% margin it earns 15. A 2x vs 0.5x weighting reflects that 4x profit gap honestly.
- Start conservative. Extreme multipliers on day one shock the learning. I start at half the mathematically "correct" adjustment and tighten over a few weeks.
- Document every tier and multiplier. Six months from now someone will ask why bids on a category collapsed. The answer should be in a sheet, not in someone's memory.
Pitfalls I have already seen
Two big ones. First, double-counting. If your cart values already send profit-adjusted conversion values, or you run scripts that rewrite values, adding PVA multipliers on top compounds the adjustment and Smart Bidding optimizes toward a fiction. Pick one layer where margin logic lives, and only one.
Second, stale multipliers. Margins move: supplier prices change, promotions come and go, shipping costs shift. A multiplier set in June can be wrong by September. Put a monthly review on the calendar, and check tier membership as well as the multipliers themselves. Also watch volume effects: aggressive downweighting can starve low-margin products that quietly recruit your best repeat customers. Keep an eye on new-customer rate per tier before you choke traffic entirely.
How PVA fits your value-based bidding foundations
PVA is a lever, not a foundation. It assumes your account already runs on accurate conversion values: clean purchase tracking, revenue flowing into Google Ads, ideally enhanced conversions, and refund adjustments so returns do not inflate values. If those basics are broken, fix them first, because multiplying a wrong value just gives you a bigger wrong value. If the basics are solid, PVA is the most direct route yet to profit bidding without rebuilding your whole measurement stack.
Bottom line
Revenue ROAS was always a proxy. Product Value Adjustments let you point Smart Bidding at the number that actually matters: the margin you keep. It is a pilot, so availability varies, but the preparation work, margin tiers, custom labels and clean values, pays off regardless. Build it now and you flip the switch the day you get access.
