Performance max. How have your results been in late 2024 ...

Performance Max has been one of the most polarizing campaign types in Google Ads history — and heading into late 2024 and beyond, the debate is far from settled. A common question in the r/PPC community is whether PMax is actually delivering or just cannibalizing existing campaign performance. The honest answer, based on managing over $350M in Google Ads spend across dozens of verticals, is that PMax can genuinely outperform traditional Search campaigns at scale — but only when you understand exactly what it's doing under the hood and how to structure it properly.

The State of Performance Max in Late 2024: What the Data Actually Shows

As practitioners often discuss on forums like r/PPC, the reported results for Performance Max are all over the map. Some advertisers are seeing PMax generate more leads than Search at significantly lower CPLs. Others are watching it burn budget on irrelevant placements with zero transparency. Both experiences are valid — and both are explainable.

In my own managed accounts, the pattern I've observed consistently is this: Performance Max excels when it has sufficient conversion data and well-structured asset groups, and it struggles badly when either of those conditions is missing. Specifically, accounts with fewer than 50 conversions per month in PMax tend to underperform dramatically compared to equivalent Search campaigns. Push past that threshold — ideally to 100+ conversions per month — and the algorithm starts doing things no human bidder can replicate manually.

Volume vs. Quality: The Core Tension

One of the most common observations from PPC practitioners is that PMax generates more leads — sometimes at nearly half the volume compared to Search. But volume and quality are not the same metric. Here's what that gap often looks like in practice:

• PMax pulls in incremental volume from Display, YouTube, Discover, Gmail, and Maps — placements where intent signals are softer than Search
• Search campaigns tend to capture higher-intent, bottom-of-funnel traffic with more predictable conversion behavior
• PMax lead quality can vary significantly by vertical — e-commerce and local services tend to fare better than complex B2B

The implication: if you're measuring PMax success purely on lead volume or even CPL, you may be missing a quality issue that only shows up downstream in your CRM, sales pipeline, or return on ad spend data.

How to Actually Audit PMax Performance (The Real Process)

Most PPC practitioners who struggle with PMax are flying blind because Google gives you limited visibility by default. Here's the structured audit process I use across all managed accounts:

Step 1: Isolate Your Channel Mix

PMax doesn't tell you where your conversions are coming from by default. Use the Campaign-level Performance Max Insights report (under Insights & Reports) and pull your asset group performance data. From there, compare:

• Search themes driving volume vs. branded vs. non-branded queries
• Asset group performance ratings — "Best," "Good," "Low" labels matter more than most people realize
• Audience signal performance: which first-party data lists or custom intent audiences are driving conversions

Step 2: Check Your Search Terms Report (Yes, It Exists)

Google expanded the Search Terms report for PMax in 2024. You can now see more of the actual queries triggering your ads. Navigate to Campaign > Insights > Search Terms and look for:

• Branded queries consuming budget that should be handled by a dedicated Brand Search campaign
• Irrelevant query themes that signal poor audience signal configuration
• High-performing query clusters that you should replicate in standard Search campaigns as a safety net

Step 3: Evaluate Asset Group Structure

A single asset group trying to serve all audiences and products is one of the top structural errors I see. Best practice is to segment asset groups by:

• Product category or service line
• Audience intent stage (prospecting vs. remarketing)
• Geography, if you have meaningfully different messaging by region

Each asset group should have a minimum of 3-5 headlines, 2-3 descriptions, 5+ images (landscape and square), and at least 1 video. If you don't provide a video, Google will auto-generate one from your images — and those auto-generated assets are almost universally terrible. Upload your own.

PMax vs. Standard Search: When to Use Each (and When to Use Both)

The real answer for most accounts in 2024 isn't "PMax OR Search" — it's both, structured intelligently. Run PMax for scale and incremental reach, and run Search to protect high-intent, high-value query territory where you want keyword-level control.

Lead Generation vs. E-Commerce: PMax Performs Very Differently

One of the most important nuances that often gets lost in general PMax discussions is that the campaign type behaves fundamentally differently depending on your business model.

E-Commerce / Shopping Accounts

For e-commerce, PMax with a product feed connected is essentially the evolution of Smart Shopping. In my experience, e-commerce accounts in the $50K-$500K/month spend range consistently see:

• ROAS improvements of 15-35% vs. legacy Smart Shopping when properly structured
• Stronger performance on seasonal peaks (PMax's cross-channel flexibility helps during high-competition periods)
• Better new customer acquisition when the "New Customer Value" goal is configured correctly

For shopping-focused PMax campaigns, always connect your Merchant Center feed and organize asset groups by product category or margin tier. High-margin products deserve their own asset groups with dedicated creative — don't let them compete internally with low-margin SKUs.

Lead Generation Accounts

This is where PMax gets more complicated. Lead gen PMax campaigns are more susceptible to the quality problem mentioned earlier. The algorithm optimizes for your defined conversion action — if that's a form submit, it will find the cheapest form submits across all placements, including low-intent Display and YouTube inventory.

Mitigation strategies for lead gen PMax:

1. Import offline conversion data. If you can connect CRM data showing which leads actually became customers, Google will optimize toward those higher-quality signals. This is the single biggest lever for lead gen PMax quality improvement.
2. Use conversion value rules. Assign different values to different lead types (e.g., a demo request vs. a newsletter signup) so PMax naturally prioritizes higher-quality conversions.
3. Exclude audience lists. Use account-level negative audience lists to exclude existing customers, low-quality lead segments, and irrelevant demographics where you have data.
4. Set a target CPA floor. If your target CPA is unrealistically low, PMax will chase volume at the expense of quality. Set a target CPA that reflects your actual customer acquisition cost, not just your front-end lead cost.

The Budget Cannibalization Question: Is PMax Stealing From Search?

This is one of the most hotly debated topics in the r/PPC community, and the answer is: yes, sometimes, but not always in a bad way.

Google's official stance is that exact match branded keywords in Search campaigns take priority over PMax. In practice, the interaction is more complex. What I've observed across accounts:

• PMax does tend to suppress non-branded Search impression share, especially for broad match keywords
• Standard exact match terms are generally protected, but phrase and broad match terms face real competition from PMax
• In accounts where Search and PMax run simultaneously without structure, 20-40% of PMax conversions can be attributed to Search-intent queries that your Search campaign would have captured anyway

The fix is structural: run PMax with tightly themed asset groups and explicit search themes, maintain your Search campaigns with exact and phrase match coverage for your most valuable queries, and audit your Search impression share metrics monthly to catch cannibalization before it erodes your Search performance.

What's Actually Working in Late 2024: Practitioner-Level Observations

Based on current account performance across retail, e-commerce, local services, and SaaS verticals, here's what's genuinely moving the needle with PMax right now:

First-Party Data as Audience Signals

Customer match lists built from CRM data — especially high-value customer segments — are the most impactful audience signal input available. Accounts using robust first-party audience signals in PMax consistently see 20-40% better efficiency than those relying solely on Google's in-market segments.

Video Assets Are a Differentiator

Since Google auto-generates video for asset groups without it, advertisers who upload quality video creative are gaining a meaningful edge on YouTube inventory. Even a simple 15-30 second product or testimonial video outperforms Google's auto-generated alternatives in click-through rate and conversion rate, in my experience.

Seasonality Adjustments and Campaign-Level Adjustments

Using the seasonality adjustment tool (under Tools & Settings > Bid Strategies) before major sale events — Black Friday, product launches, end-of-quarter pushes — gives PMax's algorithm a signal to ramp up aggressively rather than getting caught in the learning phase during your most important windows. Use a 20-50% expected conversion rate increase for 3-7 day windows around major events.

Listing Group Segmentation for Shopping

For e-commerce, breaking out listing groups by product ID for your top-performing SKUs (typically your top 20% of revenue-generating products) allows you to see product-level performance data and apply custom bids via value rules. Don't let your hero products compete for budget with your long-tail catalog.

What to Do Next: Your PMax Action Plan

Whether you're launching PMax for the first time or trying to improve underperforming campaigns, here's a concrete action plan based on what's working right now:

1. Audit your conversion tracking first. Ensure you have accurate, deduplicated conversion actions with at least 30-50 conversions per month flowing into any PMax campaign before scaling budget. If you're below that threshold, build conversion volume with Search campaigns first.
2. Separate brand from PMax immediately. Create or verify you have a dedicated Brand Search campaign with exact match brand terms. Exclude those brand terms from PMax using account-level negative keyword lists (request access via your Google rep or through the interface).
3. Build asset groups by theme, not as a catch-all. Create at least 2-4 asset groups per campaign, each focused on a specific product category, service line, or audience segment. Upload custom images and at least one real video per asset group.
4. Add search themes based on your best Search keywords. Pull your top 25 converting keywords from Search campaigns and add them as Search Themes in your PMax asset groups. This focuses the algorithm without locking it into keyword constraints.
5. Connect offline conversion data or conversion value rules. If you're in lead gen, this is non-negotiable for sustainable performance. Even a basic CRM integration passing lead status back to Google can dramatically improve PMax lead quality within 4-6 weeks.

Performance Max isn't going away — Google has made that abundantly clear. But it rewards sophisticated practitioners who understand its mechanics and structure it deliberately. The accounts seeing the strongest results in late 2024 aren't the ones who handed PMax the keys and walked away. They're the ones treating it like a powerful tool that requires the right inputs, ongoing monitoring, and a clear-eyed view of what "performance" actually means for their business.
