Not every page on your website qualifies for Performance Max. Google follows a specific set of rules before it sends paid traffic anywhere. Once you understand those rules, your campaign settings make a lot more sense.

Those rules also affect where Google sends your traffic. Automation picks the final URL on your behalf, so it pays to understand how. If you don’t know how Google Ads makes that call, your Performance Max campaign could send visitors to the wrong page. And that means fewer conversions for the same spend.

This article covers final URL expansion, asset groups, audience signals, and custom labels. You’ll also see how conversion value ties into all of it.

What Are Performance Max Landing Pages?

Performance Max landing pages are the specific pages Google selects to match a user’s search query. Google pulls these pages straight from your website, your Merchant Center feed, or both. The system picks whichever page fits the search intent exactly.

Here’s a breakdown of the landing page types Performance Max typically pulls from.

Landing Page Type	Best For
Product Pages	Ecommerce stores with a full catalogue
Category Pages	Broader searches without a specific product in mind
Service Pages	Local businesses selling a specific service
App Deep Links	Campaigns focused on app installs or engagement

Most campaigns end up using a mix of these rather than one type. Google leans on whichever page gives the user the most relevant landing experience (it checks page content and relevance first). And getting your landing pages right sets the foundation for everything else in your Performance Max campaign.

A messy website with outdated pages gives Google less to work with. So before you launch, it’s worth reviewing what your site offers.

How Final URL Expansion Decides Where Ads Point

Final URL expansion is the feature that lets Google swap your chosen URL for an appropriate match. It works within Google Ads to compare your final URL against other pages on your site. If a different page fits the search campaign more accurately, Google uses that one instead.

This is how it plays out in day-to-day campaigns:

Final URL Expansion: The Basics

As we already said, Google Ads compares your chosen URL against other pages across your domain. In our experience running these campaigns, the swap usually favours the page with the strongest match.

For example, if a category page outperforms your product page, Google sends traffic there instead. This only happens within your own verified domain, not competitor sites or unrelated pages. So you don’t need to worry about ads sending people somewhere random.

That means you still control the pages Google can choose from, even when URL expansion is active. It’s automated, but it isn’t reckless.

Can You Turn Final URL Expansion Off?

Yes, final URL expansion is fully adjustable inside your campaign settings. We usually tell clients not to switch it off completely. Turning it off entirely can limit how much reach your ads get.

Instead, add specific URLs to your exclusion list and leave the rest active. This way, Google still finds relevant landing pages without touching the ones you don’t want used. It’s a smaller, safer step than flicking the whole feature off.

Before making those changes, check your existing search campaigns. That gives you a clearer picture of what’s already working before you adjust your Performance Max settings.

Asset Groups and Audience Signals: Do They Affect Landing Pages Too?

Yes, asset groups set the URL options Google can choose from, and audience signals structure who sees them. Each asset group works like its own mini campaign inside your Performance Max campaign. Audience signals then guide Google toward the right customer segments.

Let’s look at how these two work together.

Asset Groups and Their Link to URLs

Your asset groups play a direct role in where Performance Max sends traffic. Each asset group can include a different final URL to guide relevant traffic. Grouping by product category or service type keeps your landing pages tightly relevant.

Mismatched asset groups and URLs confuse Google’s algorithm more often than you’d think. This can hurt your conversion value without you noticing right away. On top of that, it can silently drag down your bidding strategy too.

With that in mind, review your asset groups whenever you add new products or services. A quick check now saves you a major headache later. It’s a small habit that protects your ad spend.

Audience Signals: Guiding, Not Choosing

Think audience signals pick your landing pages for you? Not directly. Audience signals help Google find your target audience, but your landing page choices come from your asset groups and final URL settings.

Audience signals provide Google with extra context about your ideal customers. They support automated targeting decisions, while your campaign structure and data quality help outline the final results.

More often than not, advertisers overlook the difference between audience signals and URL selection early on. Once you separate what signals do from what URLs do, campaign settings make more sense. That’s when your customer segments start working the way they should.

Getting More Control Over Your Performance Max Landing Pages

The best part about Performance Max is you’re not completely hands-off; there’s real room to steer it. Custom labels and URL exclusions both give you a way to guide Google’s decisions.

Custom Labels: A Simple Way to Sort Products

Custom labels tag products in your Merchant Center feed by season, margin, or promotion type. You can create custom labels in just a few clicks inside your feed settings. Labels help Performance Max prioritise higher-value products without restructuring your whole campaign.

Our team leans on custom labels first whenever a client’s feed gets messy. It’s often the fastest fix with the least effort.

Plus, combining labels with conversion value data helps guide budget toward top performers. This helps Google prioritise products and services that generate higher conversion value. That’s the difference between random spend and a real bidding strategy.

URL Exclusions: Blocking Pages You Don’t Want Used

Add specific pages to your exclusion list inside campaign URL expansion settings. This stops Google from sending paid traffic somewhere it shouldn’t go.

A checklist that’s usually worth blocking:

• Block outdated pages
• Exclude unrelated blog posts that don’t match search intent
• Remove low-converting page types once you spot the pattern

We’ve reviewed enough search term reports to know exclusions save ad spend fast. A monthly check is usually all it takes to protect your results long term.

Making Performance Max Work for Your Business Goals

As you know already, Performance Max landing pages aren’t chosen at random. Google follows clear signals, and now you know what they are. Small adjustments here tend to push your campaign in the right direction.

Here’s what we’d recommend: start with URL exclusions and custom labels first, as they’re the easiest wins. Keep an eye on conversion value after that to see what’s really driving results. That’s how a good Performance Max campaign delivers stronger performance.
