Google Performance Max in 2026: New Features, Exclusions & What They Mean for Your ROAS

Performance Max is no longer the black box it once was. Google’s 2026 updates have given advertisers more control, more visibility, and more ways to protect their ad spend. But knowing how to use these new features is the difference between a strong ROAS and a wasted budget. Let’s break it down.

What's New in Google Performance Max 2026

Google has rolled out several meaningful updates to Performance Max this year — moving it from a “set and forget” campaign type to something advertisers can actually steer.

The headline changes include:

  • Audience exclusions — you can now exclude specific audience segments at campaign level, not just rely on Google’s automation
  • Placement-level reporting — for the first time, you can see exactly where your ads are running across Search, Display, YouTube, Gmail, and Maps
  • Budget transparency — a clearer breakdown of how spend is distributed across channels within a single campaign
  • Asset group performance data — more granular insight into which creative combinations are driving results and which aren’t

These aren’t minor tweaks. For UK ecommerce brands spending real budget on PMax, they change how the campaign should be managed entirely. At Digital Bees, our performance marketing team has been working these updates into every active campaign.

How Audience Exclusions Work — and Why They Matter

One of the most requested features from advertisers was the ability to exclude audiences — and Google has finally delivered. Used correctly, exclusions can directly reduce wasted spend and sharpen your ROAS.

How to put them to work:

  • Exclude existing customers from acquisition campaigns so your budget targets new users, not people who already bought from you
  • Exclude low-intent segments such as users who bounced immediately or visited a single page with no engagement
  • Exclude irrelevant demographics if your product has a clearly defined buyer profile that Google’s automation isn’t respecting
  • Layer in Customer Match lists to keep exclusions precise and based on your own first-party data

The key principle: exclusions don’t limit reach — they sharpen it. Every irrelevant impression you remove is budget redirected toward users more likely to convert.

Understanding the New Budget Reporting

Previously, Performance Max gave you a single spend figure and asked you to trust the process. The 2026 update changes that with channel-level budget reporting, so you can see where your money is actually going.

What to look for in your reports:

  • Channel split — how much is going to Search vs Display vs YouTube vs Shopping
  • Cost-per-conversion by channel — which surfaces are delivering efficient results and which are eating budget without converting
  • Impression share vs spend — are you getting proportional visibility for what you’re investing?
  • Assisted vs last-click conversions — understanding which channels are closing sales versus warming audiences

If your budget is heavily skewed toward Display or YouTube with poor conversion rates, this data gives you the evidence to act — whether that’s restructuring the campaign or adding a standalone Search campaign to reclaim control of high-intent keywords. Our performance marketing services at Digital Bees include monthly reporting built around exactly these metrics.

Making Sense of Placement Insights

Placement reporting is one of the most impactful additions in 2026. For the first time, you can see which specific websites, apps, and YouTube channels your ads are appearing on — and exclude the ones that aren’t serving you.

How to use placement data effectively:

  • Review your top placements regularly — identify which sites and apps are generating conversions versus just impressions
  • Exclude low-quality placements such as mobile game apps, low-traffic content sites, or irrelevant YouTube channels
  • Look for patterns in underperforming placements — if a category of site consistently delivers clicks with no conversions, exclude the category
  • Use placement data to inform creative — if YouTube placements are performing well, that’s a signal to invest in stronger video assets

Many brands running PMax campaigns are surprised by how broadly Google distributes spend when left unchecked. Placement insights turn that opaque process into something you can actively manage.

Adjusting Your Strategy to Maximise ROAS

With these new tools in hand, UK ecommerce brands should be revisiting how their Performance Max campaigns are structured. The 2026 feature set rewards proactive management, not passive automation.

Key strategic adjustments to make now:

  • Restructure asset groups by product category or audience intent — don’t lump everything into one group; tighter asset groups give Google better signals
  • Feed stronger audience signals — upload Customer Match lists, recent purchasers, and high-value segments to guide automation in the right direction
  • Set ROAS targets that reflect reality — overly aggressive targets cause underspend; too loose and you’re paying for volume over value
  • Run a dedicated Search campaign alongside PMax for brand and high-intent terms, so Performance Max doesn’t cannibalise your best-converting keywords
  • Review and refresh assets regularly — low-performing headlines, images, and videos drag down overall asset group quality scores

At Digital Bees, we combine PMax management with our broader performance marketing and SEO strategy to make sure paid and organic demand work together — not against each other.
