Google Ads conversion value rules let you assign or adjust a monetary value to conversions that happen without a visible transaction, so Smart Bidding optimizes toward real business outcomes instead of counting every conversion as worth the same. You set them in the conversions settings when the raw conversion has no value, or when the true value differs from what the pixel captured.
Key Takeaways
- Conversion value rules attach a value to conversions that lack one, such as lead-form submissions or phone calls, so value-based bidding has a number to optimize.
- You can set a fixed value, a valued percentage adjustment, or a custom value by audience, location, device, or audience-list segment.
- They are a modelling layer on top of measured conversions; they do not change the counted number of conversions, only the value Smart Bidding sees.
- Use them when your conversion action fires before revenue is known, when values vary by segment, or when you want to boost high-intent audiences without new tracking code.
- Value rules are a complement to enhanced conversions and conversion value tracking, not a replacement for solid first-party measurement.
What Are Google Ads Conversion Value Rules?
Conversion value rules are settings inside a Google Ads conversion action that let you tell the bid engine what a conversion is worth when the recorded value is missing or wrong. A standard conversion action records that a conversion happened and, if your site passes one, how much it was worth. Many conversions - a demo request, a newsletter signup, a call - fire without any transaction, so the recorded value is zero or blank. Value rules fill that gap by assigning a number.
The rule is applied at auction time, before Smart Bidding decides a bid. It adjusts the value attribute of a conversion rather than creating a new conversion, which means your reported conversion count stays the same while the economic signal feeding the algorithm improves. This matters because Smart Bidding strategies such as Target ROAS and Maximize Conversion Value bid toward total conversion value, so a zero-value lead looks identical to every other zero-value lead unless you differentiate it.
When Should You Use Conversion Value Rules?
Use conversion value rules when you have a conversion action whose raw value does not reflect its business worth. The clearest case is a lead that has no immediate purchase: a contact-form fill, a booked call, or a quote request. Without a value, Target ROAS treats all those leads as equally worthless and cannot learn which queries produce better leads. Assigning a representative value lets the system chase the queries that historically yield more revenue.
A second case is segmented value difference. If mobile leads close at half the rate of desktop leads, or if one region produces far higher order values, a uniform recorded value hides that. Value rules let you bump or discount value by device, location, or audience list. A third case is audience prioritization: you can add a value uplift to converters who are also on a high-intent remarketing list, nudging bids up for users more likely to buy without writing new tags.
How Do You Set a Fixed Value?
A fixed value assigns the same monetary amount to every conversion of that action. In the Google Ads UI, open Tools and Settings, choose Conversions, select the action, and open the value settings. Choose "Use a value rule" and set the rule type to fixed. Enter the dollar amount and save. From that point, each recorded conversion of that action carries the fixed value you set, unless a more specific rule overrides it.
Fixed values work best when the conversion genuinely has a stable average worth, such as a single-price trial or a standard consultation fee. They are the simplest rule to reason about and to explain to a finance reviewer, because every conversion is valued identically. The trade-off is that they ignore variation between individual conversions, which is fine when that variation is small.
How Do Value Adjustments and Custom Values Work?
Beyond a fixed value, you can apply a valued percentage adjustment or a custom value keyed to a condition. A percentage adjustment multiplies the existing recorded value by a factor - for example, increasing value by 20 percent for users in a high-LTV state. A custom value lets you set a specific number for a segment, such as a higher value for converters who are also in your "pricing page viewer" audience list.
Conditions you can key on include audience list, geographic location, device type, and a new-versus-returning split. When multiple rules match, Google Ads stacks them, so a lead that is both mobile and on a high-intent list receives the combined adjustment. Keep the stacking simple and document each rule, because several overlapping percentage adjustments become hard to audit after the fact.
Conversion Value Rules vs Enhanced Conversions vs Value Tracking
| Approach | What it does | Best used when |
|---|---|---|
| Conversion value tracking | Captures the real transaction value from your site or backend | You already know the exact order value at conversion time |
| Enhanced conversions | Recovers missing or hashed values using first-party data | Some values are lost to cookie gaps or incomplete tagging |
| Conversion value rules | Models a value where none is measured or adjusts a known one | The conversion fires before revenue is known, or value varies by segment |
The three are complementary. Value tracking is the most accurate because it reflects reality. Enhanced conversions recover data you already have but failed to capture. Value rules fill the remaining hole: conversions that have no measured value at all. You should fix measurement first, then use value rules only for the conversions that genuinely cannot carry a real number.
How Do You Avoid Over-Stating Value?
The biggest risk with conversion value rules is inventing a value that is too high, which trains Smart Bidding to overbid for leads that never pay off. Base any fixed or custom value on historical close rates and average order value, not on hope. If only 10 percent of leads close at a $500 average, a defensible lead value is roughly $50, not $500.
Review rules quarterly against actual downstream revenue. If the conversions you boosted are not producing the modeled return, lower the value or narrow the segment. Because value rules are invisible in most standard reports - they show up in the "value rule" adjustment column - build a standing review so the modeled number does not drift away from reality. Pair this with a clean conversion tracking setup so the counted events themselves are trustworthy.
How Do Value Rules Fit with Smart Bidding?
Value rules only affect strategies that bid toward value: Target ROAS and Maximize Conversion Value. If you use Maximize Clicks or Target CPA, a value rule has little effect because those strategies do not optimize to conversion value. Before relying on value rules, move the campaign to a value-based strategy and give it at least a few weeks of conversion history so the algorithm can learn.
When the strategy is value-based and the values are realistic, value rules let you steer spend toward the segments and audiences that matter without changing creative or restructuring campaigns. For teams running lead-gen on Google Ads, this is often the fastest way to improve efficiency short of fixing the site value pass-through. It also connects cleanly to value-based bidding, where the modeled value becomes the number the bid engine truly chases.
Frequently Asked Questions
Do Conversion Value Rules Change the Number of Conversions Reported?
No, conversion value rules do not change how many conversions are counted. They adjust only the value attribute attached to each conversion, so Smart Bidding sees a different economic signal while your conversion volume stays the same. The adjustment appears as a separate value-rule column, not as new conversion events.
Can I Use Value Rules with Target CPA?
Value rules have little effect under Target CPA or Maximize Clicks because those strategies do not bid toward conversion value. To benefit, switch the campaign to Target ROAS or Maximize Conversion Value, then give the strategy enough conversion history to learn from the new values before judging performance.
How Do I Pick a Realistic Fixed Value for a Lead?
Multiply your historical lead-to-customer close rate by the average customer value. If 10 percent of leads become customers and the average customer is worth $500, a defensible fixed value is about $50 per lead. Base the number on real downstream revenue, not on the ideal order size, and revisit it quarterly as close rates change.
Do Value Rules Replace Enhanced Conversions?
No, value rules complement rather than replace enhanced conversions. Enhanced conversions recover values you already have but failed to capture, while value rules model a value where none exists. Fix your direct measurement and enhanced-conversion recovery first, then apply value rules only to conversions that genuinely lack a measured value.
Google Ads conversion value rules are a modelling layer that turns valueless conversions into signals Smart Bidding can act on. Use them for lead and call conversions, vary value by segment only when the data supports it, and keep the numbers tied to real close rates. Set realistic values, pair them with a value-based strategy, and review quarterly so the modeled signal keeps matching the revenue it is meant to predict.
