Demand Gen vs PMax Trends 2025

14 Google Demand Gen vs Performance Max Trends Reshaping B2B Paid Media in 2025

Summary capsule: Google sunset Discovery Ads and migrated all advertisers to Demand Gen by Q1 2024 (support.google.com migration notes, 2023-2024), and Performance Max is now positioned as the default goal-based campaign type across Google's 2024 and 2025 product communications (business.google.com). Lunio's 2024 paid media waste analysis flagged rising B2B complaints about junk leads from automated bidding. Three other shifts matter. Channel-level controls landed inside Demand Gen in 2025, generative AI asset creation is native to both campaign types, and incrementality testing is replacing ROAS as the trust metric. B2B marketing leaders accountable for pipeline, not lead volume, should read this. This is where budgets get cut and CMOs get blamed.

This brief organizes 14 observed trends across four lenses, Market, Technology, Measurement, and Workforce. Every trend leads with named-source evidence, labels direction and maturity, and connects to a B2B pipeline implication. We refresh it quarterly because this territory will not sit still.

Bottom line. The 2025 problem is not which campaign type you pick. It is whether your conversion architecture can hold up in a CFO review. Automation without measurement is just expensive guessing.

Trend 1. Demand Gen Replaced Discovery Ads as the Default Cold-Demand Buy in 2024

Evidence: Google sunset Discovery campaigns and migrated all advertisers to Demand Gen by Q1 2024, per support.google.com migration documentation published across 2023 and 2024. The campaign type now spans YouTube in-stream, YouTube Shorts, in-feed, Discover, and Gmail in a single buy. Adsmurai's 2024 Demand Gen launch analysis documented the placement consolidation across the same period.

What changed: three separate media plans collapsed into one. YouTube moved from an experiment line into the core cold-demand channel for any B2B account that used to live in Display.

Direction: established. Maturity: mature.

Pipeline impact: B2B teams selling complex products with 90-day cycles, think mid-market cybersecurity or HR tech, lost the cleanest cold-acquisition surface they had and inherited a YouTube-first creative requirement most of them are not staffed for.

Actions:

• Rebuild any account-based media plan that was anchored to Discovery placements.
• Audit your YouTube creative pipeline before next quarter's pipeline review. If you have one video and three thumbnails, that is a production problem dressed as a media problem.
• Map this work to the unaware and problem-aware demand states so creative briefs match buyer reality.

Vintage: observed 2023-2024, mature since Q1 2024.

Trend 2. Performance Max Is Absorbing Budget Faster Than B2B Teams Can Justify It

Evidence: Google has positioned PMax as the recommended default for goal-based advertisers across business.google.com and support.google.com communications throughout 2024 and 2025. Adsmurai's 2024 PMax B2B analysis flagged the structural mismatch between PMax optimization and B2B revenue metrics.

What changed: PMax went from a retail-first experiment to the default Google wants every advertiser to use, regardless of sales cycle length or lead quality requirements.

What breaks for B2B: PMax optimizes toward the conversion signal you feed it. Feed it raw MQL form fills and it will deliver MQL form fills, including the bad ones, faster and cheaper than anything else in the account.

Direction: accelerating. Maturity: scaling.

So what: any team running PMax against raw lead volume is buying its own pipeline pollution. Counterargument: "But PMax works for us on CPL." CPL is the wrong success metric. CPL going down while SQL rate craters is not a win, it is an expensive way to train your sales team to ignore marketing leads.

Actions:

• Move the conversion signal downstream of sales acceptance before adding PMax budget.
• Set a sales-accepted-lead threshold the campaign has to clear before scaling.
• Confirm the threshold is being reported back into Google Ads, not just tracked in your CRM.

Vintage: observed 2023-2025, accelerating since Q3 2024.

Trend 3. B2B Advertisers Are Splitting Workloads Between Demand Gen for Cold Demand and PMax for Capture

Evidence: Adsmurai (2024) and Lunio (2024-2025) comparison content documents a consistent pattern of advertisers running both campaign types in parallel rather than choosing one. Demand Gen handles cold audience expansion against in-market and lookalike segments. PMax handles capture against remarketing lists and high-intent first-party signals.

What changed: the question stopped being "which campaign type" and became "how do we wire the handoff."

What breaks for B2B: without explicit audience exclusions, PMax bids against the same accounts Demand Gen is paying to introduce, and incrementality collapses.

Direction: emerging. Maturity: early.

Pipeline impact: if you sell mid-market SaaS with a 60-90 day cycle, the cost of double-paying for an account that was already in the funnel is the difference between hitting and missing your CAC ratio.

Actions:

• Build an explicit audience exclusion plan between Demand Gen and PMax.
• Map each campaign to a specific demand state so the handoff is intentional, not accidental.

Vintage: observed 2024-2025, accelerating since Q2 2024.

Bridge link: Ten Demand States framework for the audience map.

Trend 4. Lead Quality Has Replaced Lead Volume as the Board-Level Metric

Evidence: Lunio's 2024-2025 paid media waste reporting has documented rising B2B complaints about junk leads from automated campaigns. Adsmurai's 2024 B2B paid media analysis flagged the same shift in success criteria.

What changed: CFOs started asking why MQL volume is up and pipeline is flat. They are getting the answer in board decks now, not just in marketing standups.

What breaks for B2B: any paid media review in 2025 that opens with cost-per-lead instead of cost-per-SQL or cost-per-opportunity is solving last year's problem and inviting a budget cut.

Direction: accelerating. Maturity: scaling.

So what: if you cannot show pipeline-stage economics by campaign type, you will lose the budget defense.

Actions:

• Reframe every paid media report around SQL, opportunity, and closed-won contribution.
• Retire CPL as the headline metric. Keep it as a diagnostic, not a goal.
• Verify SQL and opportunity fields are populating in reporting before the next review cycle.

Vintage: observed 2024-2025, accelerating since Q3 2024.

Bridge link: pipeline-aware demand strategy.

Trend 5. Demand Gen Added Channel-Level Controls in 2025

Evidence: Google rolled out granular placement controls for Demand Gen across 2025, per support.google.com release notes, including the ability to opt out of specific surfaces and report performance by placement. Adsmurai's 2025 product update coverage corroborated the rollout timing.

What changed: the biggest 2024 advertiser complaint, opaque placement bundling, got addressed in 2025. The 2025 product reports performance by placement, lets you exclude surfaces, and gives you the controls your media plan actually needs.

Direction: established. Maturity: maturing.

Pipeline impact: B2B teams that wrote off Demand Gen in 2024 need to re-test in 2025 before next budget cycle. The product is materially different.

Actions:

• Run a 60-day Demand Gen pilot with the 2025 placement controls before the next planning cycle.
• Pull placement-level reporting into your standard cadence.

Vintage: observed 2025, maturing since Q1 2025.

Bridge link: paid media operationalization.

Trend 6. Generative AI Asset Creation Is Now Native Inside Both Campaign Types

Evidence: Google integrated generative AI for image and copy creation directly into Demand Gen and PMax campaign builders, with rollouts documented across business.google.com and developers.google.com in 2024 and 2025.

What changed: advertisers can generate creative variants without leaving the platform. Creative velocity is no longer the bottleneck. Brand governance is.

What breaks for B2B: a junior media buyer can now spin up 40 brand-adjacent image variants in an afternoon, and most B2B brands have no review workflow standing between that output and a live campaign. AI here is augmentation, not replacement. The judgment about what ships still belongs to humans.

Direction: accelerating. Maturity: scaling.

Actions:

• Stand up a brand governance workflow for AI-generated assets before this becomes an incident.
• Define which asset types are eligible for in-platform generation and which require creative team approval.

Vintage: observed 2024-2025, accelerating since Q4 2024.

Bridge link: brand and creative services for the governance model.

Trend 7. YouTube Shorts Is Now a Primary Demand Gen Surface

Evidence: Google expanded Shorts inventory inside Demand Gen across 2024 and 2025, with rollout coverage dominating advertiser-facing channels on youtube.com, the single largest source in this brief's citation set.

What changed: vertical video moved from optional to default for cold-demand B2B.

What breaks for B2B: the team producing only 16:9 webinar clips is producing assets that will not run in the placements driving the most efficient reach.

Direction: accelerating. Maturity: scaling.

Pipeline impact: for B2B categories with long buyer education arcs, Shorts is now a viable first-touch surface, but only if your creative team can produce native vertical content at cadence.

Actions:

• Add vertical-native creative to the production calendar.
• Stop repurposing 16:9 assets into 9:16 with letterboxing. It performs like the compromise it is.

Vintage: observed 2024-2025, accelerating since Q2 2024.

Bridge link: creative operations services.

Trend 8. Audience Signals in PMax Got More B2B-Friendly in 2025

Evidence: Google expanded audience signal inputs for PMax in 2025, with more weight given to customer lists, in-market segments, and detailed demographics, per support.google.com documentation refreshed in 2025. Adsmurai's 2025 PMax update coverage confirmed the timing.

What changed: the original PMax product treated audience signals as suggestions the algorithm could ignore. The 2025 version respects them more. PMax campaigns refreshed with strong first-party signal in 2025 are a different product. The customer list you uploaded two years ago did almost nothing. The one you upload now actually steers the campaign.

Direction: emerging. Maturity: early.

Actions:

• Re-test PMax against a refreshed customer list and ICP-aligned in-market segments before scaling budget.
• Treat audience signals as primary, not supplementary.

Vintage: observed 2025, early since Q1 2025.

Bridge link: audience strategy services.

Trend 9. The Conversion Signal Gap Between Google and CRM Is the Unifying B2B Problem

Evidence: Google's documentation on Enhanced Conversions for Leads at support.google.com (2024-2025) and developers.google.com implementation guides (2024-2025) repeatedly position offline conversion imports as the recommended B2B path.

What changed: Google's campaign-level conversion signals (form fills, calls, page views) sit upstream of every metric a B2B revenue leader is accountable for. SQL, opportunity, closed-won revenue. Closing the gap requires offline conversion imports, Enhanced Conversions for Leads, or a CDP wiring CRM stage changes back to Google Ads.

What breaks for B2B: any 2025 paid media plan that does not include an offline conversion import architecture is structurally incapable of optimizing PMax or Demand Gen toward revenue. The algorithm cannot optimize toward a signal it cannot see.

Direction: accelerating. Maturity: early.

Pipeline impact: define MQL, SQL, and CDP for your CFO before you defend budget. If the CRM stages are not being imported back into Google Ads, fix that first.

Actions:

• Map every CRM stage to a Google Ads conversion action.
• Import sales-accepted-lead and opportunity events as the primary optimization signals.
• If you need help wiring offline imports, the bridge link below points to the operational model.

Vintage: observed 2023-2025, accelerating since Q4 2024.

Bridge link: B2B measurement and demand services.

Trend 10. Enhanced Conversions for Leads Is Becoming Table Stakes

Evidence: Google has promoted Enhanced Conversions for Leads heavily across support.google.com and developers.google.com throughout 2024 and 2025, positioning it as the recommended path for offline lead attribution. Lunio's 2024-2025 measurement coverage names it as the floor for B2B paid media accountability.

What changed: the feature hashes lead identifiers at form submission and matches them to downstream CRM events, giving Google a usable signal for downstream optimization.

Direction: established. Maturity: maturing.

Pipeline impact: this is the minimum viable measurement layer for B2B PMax and Demand Gen in 2025. Running either without it is running blind. The benefit is concrete, higher SQL rate, lower sales rejection, and a defensible budget conversation with finance.

Actions:

• Implement Enhanced Conversions for Leads before scaling automated bidding.
• Validate match rates monthly. A degraded match rate is a degraded campaign.
• Confirm match rate appears in your standard reporting view, not just inside the conversion action settings.

Vintage: observed 2023-2025, maturing since Q2 2024.

Bridge link: demand operations services.

Trend 11. Attribution Modeling Shifted to Data-Driven by Default in 2024

Evidence: Google completed the migration away from rules-based attribution across 2023 and 2024, with data-driven attribution now the default for all conversion actions, per support.google.com policy updates published in 2023-2024. Last-click is no longer the default reporting model.

What changed: historical comparisons across 2023 and 2025 paid media performance are not apples to apples.

Direction: established. Maturity: mature.

Pipeline impact: any agency reporting that pretends the methodology change did not happen is hiding it. Year-over-year deltas need a methodology footnote.

Actions:

• Add a methodology note to every YoY paid media report.
• Reset internal benchmarks against post-migration data only.

Vintage: observed 2023-2024, mature since Q1 2024.

Bridge link: paid media benchmarks.

Trend 12. Incrementality Testing Is Replacing ROAS as the Trust Metric

Evidence: Lunio (2024-2025) has published consistently on the rising use of geo-holdout and audience-holdout testing to measure incremental lift from PMax and Demand Gen. Adsmurai's 2025 coverage notes the same pattern.

What changed: automated campaigns report strong ROAS. Holdout tests routinely show a meaningful share of that conversion would have happened anyway.

Direction: emerging. Maturity: early.

Pipeline impact: any PMax or Demand Gen budget defense in 2025 that cannot show incrementality evidence is a budget defense the CFO will eventually reject. This is how you defend budget with pipeline proof.

Actions:

• Run a quarterly geo-holdout test on PMax before next budget cycle.
• Treat incrementality as a standing line item in reporting, not a one-off project.

Vintage: observed 2024-2025, emerging since Q3 2024.

Bridge link: measurement architecture services.

Trend 13. Paid Media Roles Are Splitting Into Strategy and Operations

Evidence: Verdemedia.com and turtl.co commentary across 2024 and 2025 has documented the bifurcation of the paid media specialist role into strategy work and creative operations.

What changed: automation compressed the tactical work that used to define the role. Strategy work, conversion architecture, audience design, measurement plans, is growing. So is creative operations, asset velocity, governance, brand control. AI is augmenting both functions, not replacing them.

Direction: emerging. Maturity: early.

Pipeline impact: B2B teams hiring a generalist paid media manager in 2025 are hiring against a job description that no longer exists.

Actions:

• Split the role on the next backfill. One strategy and measurement hire, one creative operations hire.
• Rewrite the JD before posting.

Vintage: observed 2024-2025, emerging since Q2 2024.

Bridge link: marketing operations services.

Trend 14. Agency Selection Criteria Are Shifting From Platform Certifications to Measurement Architecture

Evidence: Across 2024 and 2025, the B2B agency conversation has moved from Google certification counts to measurement architecture design. This is the frontier The Starr Conspiracy has been building against for 25 years, where brand, demand, and martech actually meet.

What changed: the RFP question is no longer "how many PMax campaigns have you managed." It is "what does your measurement architecture look like before a single dollar moves."

Direction: emerging. Maturity: early.

Pipeline impact: the agency RFP that leads with PMax case studies is asking the wrong question. The right question is what the agency wires up before launch.

Actions:

• Rewrite your agency RFP around measurement architecture deliverables.
• Score finalists on conversion design, not platform badges.

Vintage: observed 2024-2025, emerging since Q3 2024.

What These Trends Mean for B2B Marketing Leaders

Three decisions matter more than the campaign-type debate. They are upstream of it.

First, fix the conversion signal before you touch the campaign. If PMax is optimizing toward form fills and your sales team is rejecting most of those leads, you are paying Google to deliver bad leads more efficiently. Enhanced Conversions for Leads plus offline conversion imports from your CRM is the floor. Anything less, and the algorithm is working against you.

Second, split the workload deliberately. Demand Gen for cold and problem-aware audiences. PMax for solution-aware and decision-state capture against high-intent first-party signals. Do not let PMax bid against your own remarketing audiences while Demand Gen is trying to introduce new accounts. The handoff needs an explicit exclusion plan.

Third, invest in creative velocity before you invest in more budget. Both 2025 campaign types reward asset volume and variety. A team running three image variants and one video against a $50,000 monthly budget is not a budget problem, it is a production problem.

Minimum viable system for 2025:

• Measurement. Enhanced Conversions for Leads, offline conversion imports, quarterly incrementality tests. Bridge to measurement services.
• Creative operations. Vertical-native video, governed AI asset generation, weekly asset refresh. Bridge to brand and creative services.
• Audience strategy. Demand-state mapping, explicit Demand Gen and PMax exclusions, refreshed first-party lists monthly. Bridge to Ten Demand States.

The Starr Conspiracy's editorial position is direct. Most B2B teams are running 2025 budgets against 2022 measurement architectures and wondering why pipeline is flat. We don't sell AI experiments. We build measurement and demand systems that hold up in a CFO review.

Direct ask: if your CRM stages are not being imported back into Google Ads, fix that before next quarter's pipeline review. Talk to us about wiring Google Ads to pipeline reality, then scaling. The campaign type is the last decision, not the first.

What to Watch, Predictions for the Next Four Quarters

1. Google will deprecate at least one more legacy campaign type by end of 2026, likely Smart Shopping holdouts or remaining Display variants, folding them into PMax or Demand Gen. Evidence: the Discovery to Demand Gen migration is the template. Horizon: 12 to 18 months. Confidence: probable.

1. B2B-specific conversion templates inside Google Ads will expand, with native lead-scoring fields and CRM stage imports becoming standard rather than custom. Evidence: the Enhanced Conversions for Leads trajectory across 2024 and 2025. Horizon: 6 to 12 months. Confidence: likely.

1. Incrementality testing will move from agency-led custom builds to a native Google Ads feature for advertisers above a spend threshold. Evidence: Google's pattern of absorbing measurement methodologies once they become advertiser demands. Horizon: 12 to 24 months. Confidence: not certain.

1. The Demand Gen vs PMax framing will be obsolete by 2027, replaced by a single goal-based campaign builder that picks the underlying type behind the scenes. Brief tangent worth flagging, this is the prediction we are least sure about, because Google's history of consolidating then re-fragmenting campaign types is not a clean line. Evidence: Google's move toward goal-based abstraction. Horizon: 24 months. Confidence: probable.

Methodology

This brief draws on Google product documentation at support.google.com, business.google.com, and developers.google.com published across 2023, 2024, and 2025; advertiser-facing analysis from adsmurai.com and lunio.ai; commentary from verdemedia.com and turtl.co; and educational content published across youtube.com by Google and the broader advertiser community. The 14 trends were selected by The Starr Conspiracy editorial team based on observed advertiser pain points, product release cadence, and pipeline-impact reports from B2B paid media operators.

"Observed advertiser pain points" means recurring issues raised in our 2024-2025 B2B paid media audits, scoped to North American B2B technology advertisers across roughly 30 account reviews in the period. We do not disclose client names, spend levels, or pricing.

This brief is directional analysis, not platform policy guidance or legal advice. It is not a setup tutorial, and it is not a substitute for Google's official documentation. Confidence is anchored to named-source evidence where available, and labeled as practitioner judgment where it is not. Regional bias skews North American. The brief is refreshed quarterly. Last updated reflects the most recent material change. The Starr Conspiracy has been building measurement and demand systems for B2B technology companies for 25 years, which informs the editorial stance throughout.

Frequently Asked Questions

Which Google campaign type is better for B2B lead generation in 2025?

Neither is better in isolation. Demand Gen wins for cold and problem-aware audience expansion, particularly on YouTube and Shorts. PMax wins for solution-aware and decision-state capture against strong first-party signals and a clean offline conversion architecture. Running both with deliberate exclusions and a unified measurement plan beats picking one.

What is the biggest measurement gap in PMax for B2B teams?

The gap between Google's conversion signal (typically a form fill) and the metric the business is accountable for, SQL, opportunity, or closed-won revenue. Without Enhanced Conversions for Leads and offline conversion imports, PMax optimizes toward whatever lead is easiest to capture, not the lead most likely to become pipeline.

How often should a B2B team refresh its Google paid media strategy in 2025?

Quarterly at minimum. Both Demand Gen and PMax receive material product updates roughly every quarter. The conversion architecture, audience controls, and placement options that defined the campaign type a year ago are not the same product today. Annual strategy reviews are not fast enough for this territory.

Should B2B teams trust Google's recommended settings inside PMax?

Use them as a starting point, not a finishing point. Google's recommendations optimize for advertiser retention and platform spend, not your pipeline efficiency. Audience signals, conversion goals, and asset group structures all need B2B-specific overrides before the campaign earns budget.

What is the single highest-priority fix for a B2B team running PMax today?

Import sales-accepted-lead and opportunity stages from your CRM as primary conversion actions in Google Ads. Everything else, audience refinement, creative governance, incrementality testing, depends on the algorithm seeing the right signal first.
