Performance Max Landing-Page Control Is a Governance Decision
Performance Max landing-page control is not only a campaign-setting decision. It is also a website-governance decision.
With Final URL expansion enabled, Google may replace the URL entered in an asset group with another relevant page on the same domain based on the user’s search intent. Google positions this as a way to improve discovery and landing-page relevance, but its own documentation also warns that campaigns can send traffic to unintended pages if exclusions are not managed carefully. See Google Ads Help: About Final URL expansion in Performance Max.
For a WordPress or WooCommerce site, that matters because one domain may contain service pages, product pages, blog posts, careers information, support content, legal pages, old campaign URLs, and thin location pages. A page can be relevant to a query without being a suitable paid destination.

Three practical Performance Max setups
1. Expansion on with broad discovery
This is the most automated option. Google can explore the site and select pages it considers relevant. It is a reasonable starting point when most indexable pages are current, commercially useful, and connected to a clear conversion path.
The tradeoff is weaker destination control. Review whether informational, administrative, recruiting, discontinued, or low-intent pages are eligible to receive paid traffic. Also check whether the page’s headline, offer, form, phone number, and tracking match the ad group’s intended audience.
2. Expansion on with URL exclusions or rules
This is often the practical middle ground. Keep discovery enabled, then exclude individual URLs or predictable sections that should not receive ad traffic. Google documents exact URL exclusions and URL rules such as URL_CONTAINS. Its examples include excluding non-commercial content such as blog, policy, or support sections. See Google Ads Help: Common AI-based controls combinations for Performance Max.
Use rules only when the site’s URL structure is dependable. A WordPress permalink change, WooCommerce product reorganization, migration, or new content template can make a previously useful rule too broad or too narrow. Treat exclusions as maintained configuration, not a one-time cleanup.
3. Expansion off with a curated page feed
This provides the tightest control. Google states that when Final URL expansion is off, the campaign sends users only to URLs provided in the page feed and asset groups. That can fit regulated offers, tightly reviewed lead-generation pages, limited product collections, or campaigns where every destination requires approval.
The tradeoff is reduced discovery. Google’s documentation describes this setup as maximum landing-page control at the cost of allowing the system to find conversion opportunities on other relevant pages. The feed also becomes an operational dependency: update it when products go out of stock, services change, redirects are introduced, or landing-page templates are retired.
A page feed is not a hard restriction while Final URL expansion remains enabled. In that configuration, Google says the feed helps verify and prioritize URLs but does not limit ads to only those URLs. See Google Ads Help: About Final URL expansion in Performance Max.
What to do next
- Inventory destinations. Review the landing pages associated with the campaign and classify each as commercial, informational, administrative, outdated, or unclear.
- Audit the WordPress experience. Check message match, offer freshness, page ownership, form behavior, phone tracking, mobile usability, accessibility, redirects, and page performance.
- Exclude obvious risks. Start with exact exclusions for careers, privacy, support, discontinued products, and pages that cannot reasonably convert the intended audience. Use section rules only where URL patterns are stable.
- Choose discovery or control deliberately. Keep expansion on when automated discovery is acceptable. Test expansion off with a maintained page feed when destination approval is more important than coverage.
- Measure lead quality downstream. Form volume is not the same as qualified demand. Where the CRM and consent process support it, map lead stages and provide reliable qualified or converted-lead outcomes to Google Ads. Google documents this approach for lead optimization, but the implementation depends on accurate identifiers, status mapping, data handling, and testing. See Google Ads Help: Multiply conversions with Performance Max.
- Validate enhanced-conversion settings. If using enhanced conversions, review Google’s customer-data requirements and confirm the implementation in Google Ads before using the data for bidding or reporting. See Google Ads Help: About enhanced conversions for web.
Landing-page governance will not fix a weak offer, poor sales follow-up, invalid lead data, or inaccurate conversion tracking. It does create a clearer boundary between what the website contains and what the business is willing to pay to promote.
