Value-Based Bidding

Conversion-based bidding treats every conversion as equal: a 10 euro order and a 5,000 euro order both count as one. Value-based bidding fixes that blind spot by sending a value with each conversion, so the algorithm can chase the most valuable outcomes rather than the most numerous. The practical difference is large. A campaign told to maximise conversions might happily pile up cheap, low-value sales; the same campaign on value-based bidding will lean into the high-value buyers, the long subscriptions, the leads that actually close, even if they are fewer in number. It is the difference between optimising for activity and optimising for money.

The whole approach stands or falls on value data. For e-commerce that is straightforward: pass the real order revenue, ideally net of returns and shipping, with each purchase. For lead generation it is harder because the value of a lead is not known at submission, so you approximate it: assign static values by conversion type, use Google Ads value rules to adjust by location, device or audience, or, best of all, import offline conversions with real downstream values once leads turn into deals. Garbage value data produces garbage bidding, so investing in clean, differentiated values is the part that actually moves results, far more than the bid strategy name itself.

You enable a value-based strategy (Maximize Conversion Value, with or without a Target ROAS) and feed conversion values into the account. Google then predicts the likely value of each auction from signals such as query, device, location, time and audience, and bids more on auctions it expects to be worth more. Value rules can adjust those predictions for known patterns, for example treating customers in a high-margin region or returning audiences as worth more. The result is a bidding pattern shaped around revenue and profit rather than a flat per-conversion view.

Most accounts have wildly uneven conversion values, yet bid as if every conversion were identical, which quietly funnels budget toward cheap, low-value actions. Value-based bidding aligns spend with the outcomes that actually drive the business, the big orders, the loyal customers, the leads that become revenue. For any account where conversions differ in worth, especially e-commerce and considered B2B purchases, moving from conversion-based to value-based bidding is one of the clearest paths to higher profit from the same budget, provided the underlying value data is trustworthy.
