What is conversion value?
Conversion value is the monetary worth you assign to each conversion so Google Ads and GA4 can optimize for revenue and profit, not just raw conversion counts. Instead of treating every form fill or sale as equal, you attach a number, real revenue or an estimated lead value, that tells the algorithm which conversions actually matter to your business.
That single shift, from counting conversions to measuring value, is what unlocks value-based bidding strategies like Maximize Conversion Value and Target ROAS. This guide explains what conversion value is, how it works in Google Ads and GA4, how to set up conversion value tracking step by step, and how to assign values to leads and micro-conversions so your campaigns chase profit rather than vanity metrics.
Why conversion value matters: from conversions to value
Two campaigns can drive the exact same number of conversions and deliver wildly different results. One generates 100 newsletter signups; the other generates 100 enterprise demo requests worth thousands each. If you bid only on conversion volume, Google treats both as identical, and your budget flows toward whatever is cheapest to convert, not what makes you money.
Conversion value fixes that. By passing a value with every conversion, you give Google's machine learning a profit signal it can optimize against. This matters more than ever in 2026: Google now requires you to choose a value option when you create a new conversion action, so value is no longer an optional advanced setting, it is part of baseline setup.
Once values are flowing, you can connect campaigns to real business outcomes, prioritise high-margin products, and report a true return on ad spend through proper analytics rather than a cost-per-lead figure that hides profitability.

A conversion value is simply a number attached to a conversion action. You decide how that number is generated, and there are two core methods: static (a fixed amount applied to every conversion of that type) and dynamic (a transaction-specific value passed through your tag or data layer).
Static vs dynamic conversion values
Static values suit consistent actions, every quote request is worth the same estimated amount, for example. Dynamic values suit ecommerce, where each order has a different basket total, or B2B where deal sizes vary; here you pass real revenue (or an imported CRM value) so each conversion reflects its true worth.
| Conversion type | How to value it | Example |
|---|---|---|
| Ecommerce purchase | Dynamic, pass real order revenue (or profit) from the data layer | $184.50 cart total sent with the purchase event |
| Lead form (B2B demo) | Static, average deal value x close rate | $8,000 deal x 12% close = $960 per lead |
| Phone call | Static proxy based on call-to-sale rate | $120 per qualified call from Google call tracking |
| Newsletter signup (micro) | Static low proxy or 0 if not commercially meaningful | $2 per signup, or 0 during early testing |
| Subscription / SaaS trial | Static expected LTV x trial-to-paid rate | $900 LTV x 20% = $180 per trial start |
In GA4, you assign value at the event level: events like purchase carry a value and currency parameter, and key events can have a default value. Those values can be imported into Google Ads when accounts are linked, so your GA4 ecommerce revenue feeds the same bidding engine that powers your search and shopping campaigns.
Conversion value vs conversion volume
The clearest way to understand conversion value is to contrast it with conversion volume, the metric most accounts default to. Optimizing for volume maximises the number of conversions; optimizing for value maximises the worth of those conversions.
| Dimension | Conversion volume | Conversion value |
|---|---|---|
| What it counts | Number of conversions | Total monetary worth of conversions |
| Bidding strategy | Maximize Conversions / Target CPA | Maximize Conversion Value / Target ROAS |
| Best for | Uniform conversions of similar worth | Varied deal sizes, ecommerce, mixed funnels |
| Risk | Chases cheap, low-value conversions | Needs accurate values, or it optimizes wrong signals |
| Headline metric | CPA (cost per acquisition) | ROAS (return on ad spend) |
Neither is universally better. If every conversion is genuinely worth the same, volume bidding is fine. The moment your conversions differ in worth, value-based bidding wins, because it stops spending equally on a $2 signup and a $5,000 contract.
How to set up conversion value tracking step by step
Setting up conversion value tracking follows the same logic whether you run ecommerce or lead generation: define the action, attach a value, and feed that value to Google consistently.
- Create the conversion action in Google Ads (Goals > Conversions). Since 2026 you must choose a value option, you can no longer skip it.
- Pick static or dynamic. Choose "Use different values for each conversion" for ecommerce revenue, or "Use the same value" for leads with an estimated worth.
- Pass dynamic values via the Google tag / GA4 purchase event, sending
valueandcurrencywith each transaction (your web team or data layer handles this). - Assign estimated values to leads using average deal value x close rate, so each form fill or call carries a realistic number.
- Import offline conversions for sales that close later, upload closed-deal revenue via offline conversion import or the Google Ads API so bidding learns from real outcomes.
- Verify in GA4 and Google Ads that values are populating, then let data accumulate for 4 weeks or 3 conversion cycles before switching on value-based bidding.
For lead-gen accounts especially, offline import is the difference between guessing and knowing. A strong lead generation setup ties CRM outcomes back to the original click, so Google learns which keywords and audiences produce real revenue, not just cheap form fills.
Value-based bidding: Maximize Conversion Value and Target ROAS
Value-based bidding (VBB) is the subset of Smart Bidding that optimizes toward conversion value instead of conversion count. It powers two strategies: Maximize Conversion Value (extract the most value from a fixed budget) and Maximize Conversion Value with a Target ROAS (hit an efficiency target with flexible budget). Note that from June 2026 Google is renaming these in the interface, "Maximize conversion value with a Target ROAS" simply becomes "Target ROAS".
Use Conversion Value Rules to adjust values by location, device, or audience without rebuilding your tagging, for instance, raising the value of conversions from high-LTV regions. Pair this with sound campaign architecture from an experienced SEM team and feed values daily rather than in large batches so the algorithm keeps learning.
How to assign values to leads and micro-conversions
The hardest part of conversion value is pricing things that don't have an obvious price, a lead, a call, a download. The trick is to work backward from money you actually earn.
- Leads: average deal value x lead-to-customer close rate. A $5,000 deal that closes 10% of the time makes each lead worth ~$500.
- Qualified vs unqualified: assign separate, higher values to sales-qualified leads so bidding favours quality.
- Micro-conversions (signups, guide downloads): use a small proxy value, or 0 if the action is informational and not commercially meaningful on its own.
- Phone calls: value them like leads, deal value x call-to-sale rate, using Google call tracking.
Counting conversions tells you how busy your ads are. Assigning conversion value tells you whether they are making you money, and machine learning can only optimize for the goal you actually give it.
A clean lead-scoring model also strengthens your wider funnel, the same intent signals that justify a high lead value should shape your content strategy and the landing pages your web design team builds to convert that traffic.
How to measure and optimize for value with ROAS
Once value is flowing, your headline metric shifts from CPA to ROAS (return on ad spend): conversion value divided by cost. A ROAS of 400% means $4 of tracked value per $1 spent. Where possible, report profit rather than gross revenue as your value, because targets built on margin are far clearer to act on.
- Watch ROAS by campaign, ad group, and audience, then use Conversion Value Rules to nudge bids toward your best segments.
- Allow a 1 to 2 week calibration window after any change before judging performance.
- Account for conversion delay, deals that close weeks later inflate apparent cost until offline data lands.
- Layer in seasonality adjustments and attribution review so the model reflects reality, not noise.
For a deeper look at the spend side of the equation, our guide to Google Ads cost and the fundamentals of Google PPC pair naturally with value-based optimization.
Common conversion value mistakes to avoid
- No values at all: leaving conversions at 0 or undefined makes value-based bidding impossible, the algorithm has nothing to optimize.
- Wrong or arbitrary values: placeholder numbers with no business logic push Google toward the wrong signals and can quietly erode profit.
- Double counting: tagging the same purchase as multiple conversion actions inflates value and corrupts ROAS.
- Revenue when profit is meant: bidding on revenue ignores margin, a high-revenue, low-margin product can look like a winner while losing money.
- Premature judgement: analysing results during the learning phase, or before offline conversions report, leads to bad decisions.
Avoiding these is largely a measurement-hygiene problem, the same discipline that underpins reliable marketing analytics across every channel.
Frequently asked questions about conversion value
How do I assign a value to a lead?
Multiply your average deal value by your lead-to-customer close rate. If deals average $5,000 and you close 10% of leads, each lead is worth roughly $500. Use higher values for sales-qualified leads and import closed-deal revenue via offline conversions so the figure stays accurate over time.
What is the difference between conversion value and conversion volume?
Conversion volume counts how many conversions you get; conversion value measures how much they are worth. Volume pairs with Maximize Conversions and CPA, while value pairs with Maximize Conversion Value and ROAS, ideal when your conversions differ in worth.
Do I need conversion values to use value-based bidding?
Yes. Value-based bidding needs at least two distinct conversion values, either real revenue or proxy values such as lead scores, plus a consistent flow of conversion data. Google recommends 15 conversions in the last 30 days and 3 conversion cycles of data before enabling Target ROAS.
What is a good conversion value to set for ecommerce?
For ecommerce, use dynamic values that pass the real order total (or profit) with each purchase event, rather than a fixed number. This lets bidding favour higher-value baskets automatically. Reporting profit instead of gross revenue gives you a cleaner ROAS target.
When should I set a conversion value of 0?
Use 0 for actions that are informational but not commercially meaningful on their own, or temporarily during early-account testing and migrations. If the conversion ultimately drives revenue, replace the 0 with a realistic value as soon as you have data.
