The B2B advertising measurement gap: New research reveals how wide it is
New research from Bombora, PrograMetrix, and AdExchanger reveals why 90% of B2B marketers lack confidence in target account reach and what it means for the future of campaign measurement.
B2B advertising is becoming more sophisticated. Marketers are using more audience data, activating campaigns across more channels, and designing programs to reach entire buying groups, not just individual leads.
But as campaign execution becomes more advanced, measurement is struggling to keep up.
That is the central finding from The Measurement Gap in B2B Advertising, a new research report from Bombora, PrograMetrix, and AdExchanger. The report surveyed B2B brands and agencies to understand how marketers are defining audiences, activating campaigns, evaluating performance, and preparing for the impact of AI on advertising strategy.
What is the B2B advertising measurement gap?
The B2B advertising measurement gap is the disconnect between increasingly sophisticated campaign execution and limited visibility into whether campaigns are reaching and influencing the right accounts and buying groups.
That disconnect matters because measurement is no longer just a reporting function. It shapes campaign optimization, budget decisions, executive confidence, and how marketing teams prove business impact.
Key findings from The Measurement Gap in B2B Advertising
The research found that:
- Only 10% of B2B marketers are very confident their audience data is effective in reaching the right accounts or buying groups.
- Only 21% of marketers measure account engagement.
- Only 7% of marketers measure buying group engagement.
- 82% say a unified measurement view of campaign performance is important or very important to internal marketing leadership.
- 91% often or sometimes manually pull performance data from multiple sources to create a unified view of campaign performance.
- Only 2% of organizations describe their B2B campaign measurement as best-in-class.
- 30% of marketers say greater reliance on AI and automation will be the biggest shift in B2B marketing over the next year.
B2B campaigns are more sophisticated than ever
Today’s B2B advertising programs are no longer built around a single audience attribute, channel, or objective. Marketers are layering multiple data sources to define their audiences, including job title, account lists, behavioral or Intent signals, buying group personas, firmographic criteria, and technographic data.
According to the report, 72% of marketers use between two and five audience data types in most B2B campaigns. Job title or role remains the most commonly used audience type, followed by account lists and behavioral or Intent signals.
This reflects a more mature approach to audience strategy. B2B marketers are trying to understand not only who buyers are, but also where they work, what roles they play in the buying process, and what signals may indicate active interest.
At the same time, B2B advertising is being used across a broader set of objectives. The report found that ad spend is relatively balanced across awareness, consideration, and decision-stage activity, suggesting that B2B campaigns are supporting the full buying journey, not just lead generation.
That shift is important. B2B buying does not happen in a single session, channel, or form fill. It unfolds across multiple stakeholders, touchpoints, and moments of engagement over time. As marketers build campaigns that reflect that complexity, measurement needs to evolve as well.
Confidence in target account reach remains low
Despite the increased use of audience data and targeting strategies, confidence remains limited.
Only 10% of B2B marketers say they are very confident their audience data is effective in reaching the right accounts or buying groups. Nearly half report less than moderate confidence.
That lack of confidence is not just a targeting issue for B2B marketers. It is a measurement issue.
When marketers cannot clearly see which accounts are being reached, which stakeholders are engaging, and whether campaigns are influencing meaningful outcomes, it becomes difficult to know what is working. More sophisticated targeting does not automatically create better performance visibility.
In fact, the report found that among marketers with low confidence, 55% said the ability to measure success would increase their confidence that they are reaching the right accounts and buyers.
In other words, better measurement isn’t just about reporting. It’s a prerequisite for trust in the campaign strategy itself.
Most measurement still doesn’t reflect how B2B buying happens
B2B campaigns are increasingly designed to reach accounts and buying groups, but the metrics used to evaluate those campaigns often remain focused on individual actions.
The report found that conversions, clicks, and site visits are still among the most widely used success metrics. Meanwhile, only 21% of marketers measure account engagement, and just 7% measure buying group engagement.
That is a fundamental mismatch.
Clicks, form fills, and site visits can signal activity, but they don’t always show whether target accounts are engaging, whether multiple stakeholders are involved, or whether advertising is influencing movement across a buying group.
For B2B marketers, that distinction matters. A campaign can generate activity without creating meaningful account-level progress. It can drive clicks without reaching the right buying committee members. It can produce leads without helping marketers understand broader engagement across the accounts they care about most.
This is the measurement gap: Campaigns are built for accounts and buying groups, but performance is often evaluated through individual-level and channel-specific metrics.
Unified measurement is a business requirement
The challenge becomes even more pronounced as campaigns span more channels and platforms.
B2B marketers are distributing investment across events, paid search, paid social, CTV, online video, programmatic display, native, sponsorships, digital audio, and other environments. The report notes that budgets are spread across nine or more channels, making consistent measurement more difficult.
Marketers recognize the importance of solving this. According to the research, 82% say having a unified measurement view of campaign performance is important or very important to internal marketing leadership.
But unified measurement is rarely available out of the box. The report found that 91% of marketers often or sometimes manually pull performance data from multiple sources to create a single, consistent view of campaign performance.
The biggest barriers are inconsistent metrics and platform silos, each cited by 66% of marketers.
This limits a marketer’s ability to compare performance across channels, understand how campaigns are working together, and make confident decisions about budget, targeting, and optimization.
Measurement is now visible beyond marketing
The report also found that campaign performance is reviewed by marketing leadership at 67% of organizations and by executives at 53% of organizations. Sales, RevOps, marketing operations, and finance are also involved in evaluating campaign performance.
That broader visibility raises the stakes. Measurement is not just used to optimize campaigns. It informs business decisions, budget allocation, executive reporting, and organizational alignment.
Yet most organizations are still developing their measurement capabilities. Only 2% of respondents describe their B2B campaign measurement as best-in-class, while 59% describe it as early stage or developing.
This gap between visibility and maturity creates tension. More stakeholders want performance answers, but many marketing teams are still working with fragmented data, incomplete metrics, and manual reporting processes.
AI will make stronger measurement even more important
The measurement gap may widen as AI becomes more embedded in B2B advertising.
According to the report, 30% of marketers say greater reliance on AI and automation will be the biggest shift in B2B marketing over the next year. Nearly half say AI will have the greatest impact on audience targeting and segmentation, while 45% expect it to impact creative development and optimization.
By comparison, only 25% expect AI to have its greatest impact on measurement and attribution.
That finding is a warning sign.
If AI accelerates campaign execution, segmentation, creative testing, and media optimization faster than measurement improves, marketers may face even more complexity with limited visibility into what is actually driving outcomes.
AI can help marketers act faster. But without stronger measurement, it may also make it harder to understand which actions are working, which audiences are responding, and which signals are meaningful.
Closing the B2B advertising measurement gap
The path forward requires a shift in how B2B marketers think about campaign performance.
Measurement needs to reflect how B2B buying actually happens. That means moving beyond isolated actions and channel-specific reporting toward a more connected view of account engagement, buying group activity, and campaign influence over time.
The report’s call to action is clear: organizations need the ability to connect media exposure to account-level engagement and buying-group activity. With that visibility, teams can move beyond proxy metrics and identify which accounts are progressing, which stakeholders are engaging, and where advertising is contributing to results.

Frequently asked questions about B2B advertising measurement
What is B2B advertising measurement?
B2B advertising measurement is the process of evaluating whether advertising campaigns are reaching the right accounts, engaging the right stakeholders, and contributing to business outcomes such as account engagement, pipeline influence, revenue, or buying group progression.
What is the B2B advertising measurement gap?
The B2B advertising measurement gap is the disconnect between how B2B campaigns are executed and how they are measured. Campaigns are increasingly built to reach accounts and buying groups across multiple channels, but many marketers still rely on individual-level or channel-specific metrics such as clicks, form fills, and site visits.
Why is B2B advertising measurement difficult?
B2B advertising measurement is difficult because B2B buying journeys often involve multiple stakeholders, long decision cycles, multiple channels, and fragmented platform data. This makes it hard for marketers to understand whether campaigns are reaching the right accounts, influencing buying groups, and contributing to outcomes over time.
Why does account-level measurement matter in B2B advertising?
Account-level measurement matters because B2B buying decisions are usually made by groups of stakeholders within an organization, not by one individual. Measuring account engagement helps marketers understand whether target accounts are showing meaningful activity across the buying journey.
What is buying group engagement?
Buying group engagement refers to activity from multiple stakeholders involved in a B2B purchase decision. Measuring buying group engagement helps marketers understand whether advertising is reaching and influencing the broader set of people involved in evaluating a solution.
What is unified campaign measurement?
Unified campaign measurement is a single, consistent view of campaign performance across channels and platforms. It helps marketers compare performance, understand cross-channel influence, and make more confident decisions about budget, targeting, and optimization.
Why is AI making B2B advertising measurement more important?
AI is expected to make B2B advertising execution more sophisticated by improving audience targeting, segmentation, creative development, and optimization. As campaigns become more automated and complex, marketers need stronger measurement to understand what is working and where advertising is creating real impact.
