Google ads conversion value rules explained: a feature inside Google Ads that lets you adjust the reported and bidding value of a conversion based on who converted, where they were, or what device they used — without changing your conversion tracking code. If you run Google Ads in South Africa and every lead or sale gets the same value regardless of its source, Smart Bidding has no way to know which clicks are actually worth more to your business. Conversion value rules close that gap.
South Africa's online market underscores why this matters. Mobile devices account for 72.7% of web traffic and 51.7% of purchases (Netcash, December 2024 data) — yet for many B2B advertisers and higher-ticket service businesses, the desktop buyer still converts at a higher order value. Treat both identically and you're effectively subsidising low-value clicks with budget that should chase high-value ones.
Quick Answer
Google ads conversion value rules explained in brief: they are account- or campaign-level rules that tell Google's Smart Bidding to treat certain conversions as more (or less) valuable than others, based on the user's location, device type, or audience membership. You configure a condition (e.g., Gauteng region) and an operator — Add a fixed amount, Multiply by a factor between 0.5 and 10, or Set a fixed value (beta) — and Smart Bidding applies that adjustment at auction time for Target ROAS and Maximise Conversion Value strategies. They work on Search, Shopping, Display, and Performance Max campaigns.

Every conversion value rule is built around at least one condition — the trigger that determines which conversions the rule applies to. Google Ads currently supports four condition types, three of which are available to most advertisers.
| Condition Type | What it adjusts for | SA Use Case |
|---|---|---|
| Location | Country, region, city, or zip/postal code where the user is located or has shown interest | Multiply conversions from Gauteng by 1.5 if your lifetime customer value is higher there |
| Device | Mobile, desktop, or tablet | Add value to desktop conversions if your data shows desktop buyers spend more per order |
| Audience | First-party lists (Customer Match), Google remarketing lists, affinity or in-market audiences | Multiply conversions from your CRM-uploaded repeat-buyer list — they have higher retention value |
| No Condition | No filter applied | Only available for store visit or store sales conversion actions |
Each rule can carry a primary and an optional secondary condition — but the secondary must be a different type from the primary. If your primary is Location, your secondary could be Device or Audience, not another Location. When two locations are selected within the same condition, the rule triggers for either location — not both simultaneously.
Account-wide constraint to know: All value rules in your account must use the same type of primary (and secondary) conditions. If you want to switch from location-primary rules to audience-primary rules, you'll need to delete all existing rules first. Plan your rule structure before you build — it is harder to restructure mid-flight.
Location conditions: the Gauteng vs. rural split
For SA advertisers, location conditions are often the first place to act. A Johannesburg or Cape Town enquiry for a premium B2B service is frequently worth more than the same conversion from a smaller centre — not because rural customers are less valuable, but because geographic purchasing power, order size, and proximity to your fulfilment or service area are real business variables. Assigning a higher multiplier to Gauteng or the Western Cape lets Smart Bidding compete harder for those clicks without you manually adjusting bids at keyword level.
Device conditions: the mobile traffic problem in SA
With 72.7% of SA web traffic arriving on mobile (December 2024), most accounts have a heavy mobile skew in their click data. If your data shows desktop sessions convert at a higher average order value — common in B2B, professional services, and considered-purchase retail — a device condition lets you tell Smart Bidding to reflect that difference. Rather than under-bidding on desktop or overpaying for mobile, the algorithm weights bids correctly at auction time.
Audience conditions: your CRM list is an asset, not just a targeting option
First-party audience lists uploaded via Customer Match can be used as the condition trigger. If a conversion comes from someone already on your customer list, you can multiply that conversion value to reflect higher retention probability. This is particularly useful alongside Google Ads conversion tracking setups where lifetime value differs meaningfully from first-purchase value — subject to your organisation's POPIA data-processing agreements, first-party customer data can make this segmentation achievable for SA businesses.
Key Takeaway: Conditions are your segmentation layer
Conversion value rules do not change which conversions happen — they change how much Smart Bidding is willing to pay for the click that leads to them. Think of each condition as a way to inject business logic (margins, geography, customer tier) into the bidding algorithm that Google would otherwise have no visibility of.
How the Value Operators Work: Add, Multiply, or Set
Having google ads conversion value rules explained at condition level is the first step; the operator determines the magnitude of the adjustment. Each rule applies one of three operators — Add, Multiply, or Set — and the choice between them depends on whether your segment data points to a fixed or proportional difference in conversion value.
| Operator | How it works | Best for | Range |
|---|---|---|---|
| Add | Adds a fixed positive amount on top of the existing conversion value | Adjusting lead values by a known increment when your CRM data shows a measurable deal-size difference between segments | Any positive number |
| Multiply | Scales the existing conversion value by the entered factor | Proportional adjustments when your base value varies across products or campaigns | 0.5 to 10 |
| Set (beta) | Replaces the existing conversion value with a fixed amount | Situations where you want to override all incoming values with a single number | Any positive number |
Practical example — Multiply: Your lead gen campaign passes a fixed default conversion value for all enquiries. Your CRM data shows repeat customers from your loyalty list close at roughly twice the revenue of first-time buyers. You create a rule: Audience = CRM loyalty list, operator = Multiply 2. Smart Bidding now treats those conversions at double the default value and bids more aggressively when it recognises an audience match — without you touching a single keyword bid.
Common mistake — Add on variable-value campaigns: If your ecommerce campaign already passes dynamic revenue values — a low-value order and a high-value order in the same product range — adding a fixed flat amount to every conversion distorts the relative differences between transactions. Multiply is almost always the right operator when your base values are dynamic — it scales proportionally rather than flattening variance.
Which Google Ads Campaign Types Support Conversion Value Rules?
Conversion value rules are not available on every campaign type. Compatibility matters because many SA accounts now run a mix of campaign formats after the broader rollout of Performance Max.
| Campaign Type | Conversion Value Rules | Notes |
|---|---|---|
| Search | ✓ Supported | Works at account or campaign level |
| Shopping | ✓ Supported | Works at account or campaign level |
| Display | ✓ Supported | Works at account level |
| Performance Max | ✓ Supported | Campaign-level rules apply; also supports retail goals |
| Hotel / Travel (itinerary) | ✓ Limited | Itinerary conversion value rules only; separate setup path |
| Video / Demand Gen / App | ✗ Not supported | Use separate conversion goal configuration for these |
Campaign-level rules only affect bidding within that campaign — they don't bleed across to other campaigns unless you're running a portfolio bid strategy, in which case minor cross-campaign interactions can occur. Account-level rules apply across all supported campaign types simultaneously.
Key Takeaway: Performance Max + value rules
Performance Max campaigns support conversion value rules, which makes them more controllable than many advertisers assume. If you run PMax for South African retail and your Gauteng customers have a demonstrably higher average basket, a location-based value rule gives the algorithm the information it needs to skew asset delivery and bids accordingly — rather than spreading budget uniformly.
How to Set Up Conversion Value Rules in Google Ads
Setup lives inside the Goals workflow, not the campaign settings. Here is the path and what to expect at each step.
- Open your account and click the Goals icon in the left navigation.
- Under Conversions, select Value rules.
- Click Create conversion value rule.
- If you are tracking store visits or store sales, select the relevant conversion goal. For standard web conversions, skip this step.
- Set your primary condition: choose Audience, Device, Location, or No Condition.
- Optionally add a secondary condition of a different type.
- Review the If / And / Then preview Google generates — confirm the logic reads correctly.
- Choose your operator: Add, Multiply (enter a value between 0.5 and 10), or Set (beta).
- Save. The rule becomes active and Smart Bidding applies it at the next eligible auction.
Data readiness check: Conversion value rules feed Smart Bidding strategies like Target ROAS and Maximise Conversion Value. Target ROAS requires at least 15 conversions with valid values in the past 30 days (Search and Shopping campaigns) before the strategy can optimise reliably. If your account is below that threshold, set up value rules now but switch to Maximise Conversion Value first — then layer in a ROAS target once volume builds. See SA ROAS benchmarks for context on what targets are realistic in your vertical.
Once your value rules are configured, the impact appears in your next Smart Bidding cycle — no campaign pause required. Full official documentation is available in Google's conversion value rules guide and the step-by-step setup reference.
What Happens When Multiple Rules Apply to the Same Conversion?
Only one value rule can apply to any given conversion. According to Google's official conversion value rules setup documentation, the platform applies a defined resolution hierarchy when more than one rule could match:
- Location: the most precise rule wins. A rule set to "Cape Town" overrides a rule set to "Western Cape" which overrides a rule set to "South Africa".
- Audience: Google follows a pre-defined audience hierarchy; for the current ordering, consult the conflict resolution section of Google's value rules setup guide.
- Device: no conflict is possible — mobile, desktop, and tablet are mutually exclusive categories.
This hierarchy matters when you are building rules for overlapping geographic or audience segments. The safest approach is to design rules from most-specific to least-specific and confirm the preview logic in the interface before saving.

Dirk built and scaled a South African ecommerce operation before founding Growth Pulse Media — paying the invoices, watching the ROAS reports, and working out which levers actually moved revenue. That experience shapes how we configure accounts: with google ads conversion value rules explained correctly and built on real segment data, Smart Bidding gains the business-logic input it needs to weight bids toward higher-margin segments — rather than treating all conversions as equivalent.
We see accounts with Multiply set on campaigns that pass dynamic revenue values, or location rules covering "South Africa" as the primary when the account needs provincial-level precision.
Our Google Ads management service covers value rule architecture from the start: auditing what your current conversion tracking passes, identifying which condition type fits your customer geography and segment data, and building a rule set that gives Smart Bidding the business logic it needs. We run a limited client load so every account gets senior attention — not a templated rule set applied at scale.
Named platforms we work with daily include Google Search, Shopping, Performance Max, and Display, alongside GA4 for the underlying conversion data that feeds value rule decisions. For SA businesses running Customer Match, we handle the data preparation and upload process with attention to POPIA requirements — including consent-based data sourcing, defined retention periods, and no third-party sharing — subject to each client's data-processing agreements.
Who Conversion Value Rules Are NOT Right For
Conversion value rules are a precision tool — they amplify Smart Bidding only when your account has clean conversion data and verifiable segment differences to act on. Four situations where deploying them before you are ready creates more noise than signal:
You don't track conversion values at all. If your conversion actions are set up as "goal completions" with no value attached, there is nothing for a value rule to adjust. The feature requires at least a baseline conversion value — even a fixed placeholder value — before the operator has anything to multiply or add to.
You're in housing, employment, or credit. Google's personalised advertising policies restrict certain value rule conditions for advertisers in these categories. Audience-based conditions that use demographic signals may not be available, and attempting to configure them will result in a policy block. Check Google's sensitive categories guidance before building your rule set.
Your account is below the Smart Bidding data threshold. Conversion value rules are designed to feed value-based Smart Bidding strategies. If you're running fewer than 15 conversions per 30 days on Search or Shopping, the algorithm doesn't yet have enough signal to act on value differences reliably. Publish the rules to your account now, but wait until conversion volume is stable before switching bidding strategies.
You haven't verified your baseline value assumptions. A Multiply of 2 on Western Cape conversions for a tourism or hospitality campaign sounds logical — but only if your booking or deal data actually confirms those customers spend at twice the value of the next region. Applying a multiplier based on intuition rather than data corrupts Smart Bidding's signal and will cause the algorithm to overspend on a segment that may not justify it. Do the segment analysis in GA4 or your CRM first, then build the rule.

Do conversion value rules change the actual revenue or value I report in Google Ads?
Yes, for reporting and for Smart Bidding — but not your underlying conversion tracking code. When a rule applies, the adjusted value appears in your Google Ads conversion reports and is used by Smart Bidding at auction time. If you want to see the original (pre-rule) value alongside the adjusted value, the conversion value rules report in Google Ads shows both. Your Google Analytics or CRM data remains unaffected.
Can I use conversion value rules with Performance Max campaigns?
Yes. Performance Max supports conversion value rules at the campaign level. This is particularly useful for SA retail accounts where Gauteng or Cape Town customers have a higher average basket — location-based rules give PMax the geographic value signal it needs to allocate assets and budget more efficiently. Set the rule at account level if you want it to apply across PMax and your other supported campaign types simultaneously.
What is the multiply range for Google Ads conversion value rules?
The multiply operator accepts values between 0.5 and 10. A multiplier below 1 (e.g., 0.5) reduces the conversion value — useful if you want Smart Bidding to bid less aggressively for a specific segment without excluding it entirely. A multiplier above 1 increases it. The Add operator has no upper limit, and the Set operator (currently in beta) replaces the existing value entirely with the number you enter.
How do account-level and campaign-level conversion value rules interact?
Account-level rules apply across all supported campaign types simultaneously. Campaign-level rules apply only within that specific campaign and do not affect bidding or reported conversions in other campaigns. When both exist, the campaign-level rule takes precedence for that campaign. The exception is portfolio bid strategies: if multiple campaigns share a portfolio strategy, a campaign-level rule may produce minor cross-campaign interactions — Google recommends checking portfolio settings before mixing rule levels within a shared strategy.
Do conversion value rules work alongside Target ROAS bidding?
Yes — that is the primary use case. Target ROAS works by optimising bids toward the value you have reported for each conversion. If that value does not reflect real business differences between segments, ROAS targets become blunt instruments. Conversion value rules let you inject margin, geography, or customer tier data so that ROAS targets and the algorithm's bid decisions are calibrated against your actual business performance, not just a flat conversion count. For Search and Shopping, Target ROAS requires at least 15 conversions in the past 30 days before it can optimise reliably — see our guide to Google Ads conversion lag for related timing considerations.
