Conversion Value Rules for Prioritizing High-Quality B2B Leads

Smart Bidding does exactly what you tell it to do. That's the problem. Tell Google to maximize conversions, and it will maximize conversions. In B2B, that instruction is often wrong, because "conversion" gets treated as one flat category when it's actually a pile of very different outcomes wearing the same label.

Here's what "optimizing for form fills" looks like in practice: cost per lead drops, volume goes up, and everyone nods along in the marketing meeting. Then sales opens the CRM three weeks later and finds students doing homework for a class, competitors snooping around, and people who were never going to buy anything from anyone.

The algorithm has no built-in way to tell a high-value enterprise deal apart from someone downloading a whitepaper just to get past a form field. Unless you teach it the difference, it treats both the same way. That's what conversion value rules are for. They tell Smart Bidding which leads actually matter, turning it from a machine chasing form fills into one chasing revenue.

What conversion value rules are and what they actually control

Google describes them as multipliers applied to conversion values based on audience, device, or location. A value rule doesn't change what counts as a conversion — it changes how much the algorithm thinks that conversion is worth. Set the value higher, and Smart Bidding fights harder for that kind of person in that auction. Set it lower, and it eases off. Three levers, that's it:

• Audience — who converted
• Device — what they converted on
• Location — where they converted from

These only do anything inside Smart Bidding strategies that bid on value in the first place, mainly Target ROAS and Maximize Conversion Value. Run Maximize Conversions with no value component attached, and this whole lever just sits there unused.

One thing value rules will never do: filter out junk. They won't clean up your reporting, restructure your campaigns, or fix broken tracking. If your tracking is already sending bad signals, value rules just make the algorithm chase those bad signals with more confidence. Get tracking right first. Everything else depends on it.

How to assign conversion values that reflect actual revenue potential

The math isn't hard: close rate times average deal value, for each conversion type you track. A demo request that closes at a meaningful rate on a large average deal is worth more than an ebook download closing rarely on a smaller deal. The formula tells you exactly how much more.

Nailing the exact dollar figure matters less than getting the spread right. If a demo request is worth 20 times more than a content download, that ratio is what Smart Bidding actually reacts to. Whether the top number is slightly higher or slightly lower barely moves the needle. Whether it's 20 times the bottom number or 3 times the bottom number changes everything about how the algorithm bids.

Think in stages, and get more precise as leads move down the funnel:

• Early-stage (form fills, content downloads): a fixed expected value, based on the historical close rate from that entry point.
• Mid-funnel (demo requests, pricing page visits): higher value, still an estimate, but a better-informed one.
• Late-stage (MQL, SQL, opportunity): pull real pipeline value from the CRM wherever you can.
• Closed-won: send the actual deal amount. This is the one event that unlocks real ROAS bidding, because it's not a guess anymore. It's what happened.

Audience segments need their own layer of adjustment. Build firmographic lists by company size, industry, or job title, and enterprise segments can carry a multiplier above baseline. Out-of-ICP or SMB segments get a downward multiplier. The algorithm doesn't stop bidding on them entirely — it just stops fighting so hard for them.

Device works the same way. Mobile conversions close at a lower rate than desktop in a lot of B2B accounts. A downward multiplier on mobile doesn't punish mobile traffic; it tells Smart Bidding this still counts, just don't get too excited about it.

Set these values once and forget about them, and you're quietly steering your bidding toward last year's economics. Close rates shift. Deal sizes shift. Revisiting the numbers isn't optional upkeep. It's the job.

Closing the loop with offline conversion import

Even a carefully built value rule is still a guess dressed up as a number. It's what should happen, not a record of what did. Offline conversion import (OCI) is how you close that gap, feeding the system actual outcomes instead of stand-ins.

Google matches a CRM outcome, an MQL, an SQL, a closed deal, back to the original ad click using the GCLID, the click ID attached the moment someone clicks your ad. Once that link exists, both reporting and bidding shift away from "did they fill out a form" and toward "did this turn into something real." That matters a lot in B2B, where sales cycles routinely run past 90 days and plenty of deals close through phone calls and meetings that never touch a landing page again.

Four pieces need to work together to make this happen:

1. Capture the GCLID the moment someone submits a form.
2. Store it in the CRM, attached to the contact or deal.
3. Build an import conversion action in Google Ads for each downstream stage you care about.
4. Push closed events back to Google, either by CSV upload or an automated integration. HubSpot and Salesforce both support this out of the box.

Google's current recommended approach is Enhanced Conversions for Leads, which adds hashed first-party customer data on top of your existing conversion tags in a privacy-safe way. That data gets matched against signed-in Google accounts and traced back to the original ad. Per Google Ads Help Documentation, advertisers using this approach saw a median 10% increase in conversions compared with standard OCI alone.

There's also a deadline worth flagging if you manage this in-house: starting June 15, 2026, legacy offline conversion import and Enhanced Conversions for Leads uploads move over to the Data Manager API. Developer tokens sitting inactive between January and June 2026 lose their allowlisting for the old system. If your OCI pipeline is running on older infrastructure, this is exactly the kind of thing that breaks silently, then shows up months later as a data gap nobody can explain.

A simple way to divide the work: in-page tags handle form fills and page-level events — that's Enhanced Conversions' job. OCI handles everything after the form: MQL, SQL, opportunity, closed-won, the stages that live in the CRM, including the real closed-won deal amount.

What the algorithm does with better value signals — and what the data shows

Google's own data from 2023 to 2024 shows advertisers pairing Smart Bidding with conversion value rules saw ROAS improve by up to 20%. Same budget, spent smarter.

The same data showed audience-based value rules shifting up to 40% more spend toward high-value users, with no increase in total budget. What the algorithm is doing, at auction speed, across thousands of decisions a day, is what a human bid manager would try to do by hand given infinite time: push harder where the economics justify it, back off where they don't.

What does that look like inside an account? High-ICP audiences start getting more competitive bids. Out-of-ICP audiences see the algorithm pull back, not because you excluded them, but because you told the system they're worth less and it acted on that. Device-level rules cut wasted mobile spend without a single manual bid modifier. Geographic rules push spend toward the regions where deals close, and close bigger.

Value rules get oversold sometimes, so let's be honest about what they can't do. They won't fix a weak offer. They won't fix a landing page that loses people the second it loads. They won't fix targeting aimed at the wrong buyer in the first place. What they do is sharpen the algorithm's judgment about who's worth bidding on. The upstream decisions about who you're going after and what you're saying to them are still yours to make.

As OCI feeds more closed-won data into the system over time, the value estimates get sharper. Each new campaign builds on everything that came before.

How value rules connect to the broader B2B paid media system

Value rules are one layer in a much bigger stack. Attribution has to be sound before you can trust value rules at all.

Last-click attribution, still the default in a lot of accounts, systematically underpays early-funnel touchpoints (a LinkedIn impression, an awareness-stage article) while overpaying whatever branded search term someone typed right before converting. Multi-touch or data-driven attribution gives OCI a fuller picture of what actually drove a closed deal, which means your value rules train on something closer to the truth.

Google and LinkedIn aren't doing the same job in a B2B funnel, so value rules apply to them differently. Google tends to catch late-stage, high-intent demand: branded search, competitor terms, direct response traffic. That's where value rules show up in bidding almost right away. LinkedIn does slower work, building pipeline months before someone's actively looking, through Thought Leader Ads and account-level retargeting. The value from that spend takes longer to show up in the CRM, because the deal it influenced might not close for months.

Per the 2024 Dreamdata B2B benchmark, 39% of total B2B ad budget goes to Google Search Ads, the single biggest chunk of the mix. That's exactly why getting value rules right on Google carries so much weight for the program overall.

The cost comparison between the two platforms tells its own story. LinkedIn's cost per lead often runs around $300, versus roughly $70 on Google, a gap that makes LinkedIn look bad in isolation. But cost per company influenced flips the story: around $82 on LinkedIn versus $129 on Google, because LinkedIn is reaching several people inside the same target account, not just one form-filler. A deal that closes on Google's last click often has LinkedIn's fingerprints all over the earlier stages, fingerprints that GCLID tracking alone will never show you without deliberate cross-platform attribution work.

The number that cuts through most of the noise in B2B is cost per closed-won deal. You can only calculate that accurately if value flows cleanly from the ad click, through the CRM, through OCI, and back into platform reporting without breaking anywhere along the way.

One more thing worth saying: programs where someone is actually watching this loop, in-house, agency, or some blend with automation doing the execution, hold up a lot better over time than a value rule setup configured once at onboarding and never touched again.

Operationalizing value rules: what ongoing management actually requires

The most common way value rules fail isn't a bad setup. It's a good setup that nobody ever revisits. Values that matched reality eighteen months ago quietly steer bids toward economics that no longer exist, and nothing alerts you when that happens.

A few things should send you back to refresh the numbers:

• Close rates shift, from a new product launch, a new ICP focus, or a change in the sales process.
• Average deal size moves, up from an enterprise push, down from expanding into a new segment.
• New audience segments show up that weren't part of your original framework.
• OCI data shows a conversion stage performing differently than the proxy value you originally guessed.

How do you know the whole thing is actually working, beyond ROAS ticking up? Look at who's converting, not just how many. Is the mix shifting toward your real ICP, or just getting bigger? Is sales telling you, unprompted, that pipeline quality from paid has gotten better? Is ROAS improving against actual closed-won revenue, not the estimated values the platform hands you?

There's a governance question that gets skipped way too often: who actually owns these numbers? Close rate and deal size live in the CRM, which usually means revenue ops or sales owns them, not whoever runs the ad accounts. Keeping value rules accurate takes a real working relationship between marketing, revenue ops, and whoever manages the accounts, because the numbers underneath it come from business judgment the algorithm has no way to generate on its own.

What that means in practice: accounts where one person set the value rules during onboarding, and nobody's touched them since, drift out of calibration within a few quarters. Nothing breaks loudly. It just gets a little worse, deal by deal, until someone finally asks why cost per closed-won crept up while cost per lead looked fine the whole time. The programs that catch this before it turns into real wasted spend are the ones built around someone actually checking back in. Thunder, an applied-AI company whose agents run Google and LinkedIn Ads end to end for sales-led B2B companies, with named Forward Deployed Marketers accountable for outcomes, is one way teams delegate that ongoing stewardship rather than leaving it to whoever configured the account at launch.
