Value-Based Bidding

Your Google Ads campaign is hitting its conversion targets. The algorithm is finding buyers. It doesn’t know a $180 order matters more to your business than a $22 one.

How it shows up in the wild

Lyra PPC (94 Google Ads accounts, $3.01M in spend, June 2025–April 2026): Accounts running Maximize Conversion Value averaged 6.44x ROAS. Accounts running Maximize Conversions averaged 1.96x — with similar adoption rates across both groups — a 3.3x performance gap between campaigns passing revenue signals and those treating all conversions as equal, per Lyra PPC’s State of Google Ads 2026 analysis.

Google (platform benchmark, documented by CustomerLabs): The median conversion value lift when switching from Target CPA to Target ROAS with value signals is 14%. Fashion and home goods brands see the widest spread — categories where the algorithm can’t distinguish a $180 jacket from a $22 accessory without a differentiated signal coming back through the conversion event.

Aerie (Meta value rules, ecommerce brand): The women’s lifestyle brand identified 50 designated market areas where brand awareness was low and used Meta’s value rules to increase bids specifically in those geographies, per a 2025 breakdown of Meta’s value-based delivery tools. Value rules on Meta work differently than Google’s tROAS implementation — they apply multipliers to the bid based on audience, placement, or geography, rather than requiring explicit revenue values per conversion.

ATTN Agency (DTC account analysis): Brands running $50K+/month on Google Ads without value-based signals are described as leaving the largest single optimization lever untouched. The implementation involves passing product-level margin — not just order revenue — back to Google so Smart Bidding can optimize for profit dollars rather than gross conversion value.

Why it matters

A brand with a $20 entry product and a $200 flagship will have the algorithm drift toward the $20 order without a value signal. Lower-priced items typically convert at higher rates. The algorithm follows signal volume, not margin, unless you tell it otherwise.

The mechanic also extends to profit, not just revenue. Passing margin-adjusted values — a $10 item at 60% margin outranking a $30 item at 8% — is the logical endpoint. My hunch is that this is where the largest unlocks live for brands with varied cost structures, though it requires clean, real-time cost-of-goods data piped into conversion tracking.

Frequently asked questions

Isn’t this the same as Target ROAS? Target ROAS is the bidding strategy. Value-based bidding is what makes Target ROAS meaningful. Without differentiated value signals, tROAS optimizes toward a ROAS target calculated from conversion values that may be identical for every order — which is effectively Target CPA in a ROAS wrapper. The two work in combination: VBB is the data layer, tROAS is the optimization strategy sitting on top of it.

How many conversions are needed before switching? Google’s threshold for Target ROAS is 50 conversions in the last 30 days. Below that, the algorithm lacks the data to learn the value-to-bid relationship reliably and can underperform a simpler bid strategy. Most practitioners recommend starting with Maximize Conversion Value (no ROAS target) to accumulate data before layering in a tROAS constraint.

Does value-based bidding work on Meta? Meta’s equivalent is Value Optimization — available inside Advantage+ and manual conversion campaigns, it weights delivery toward users predicted to convert at higher purchase values. Meta infers value from the pixel’s Purchase event rather than requiring explicit per-conversion value tags in the bid logic, which makes the setup lighter but gives less direct control than Google’s approach.
