Across our 217-quote research corpus on Google Ads automation failures, one complaint appears repeatedly from ecommerce founders and media buyers: paid clicks landing on blog posts, shipping policy pages, return instructions, and store locators. When Final URL expansion in Performance Max, AI Max for Search, or Dynamic Search Ads is left unguarded, Google crawls your entire domain and treats high-traffic informational pages as valid destinations for paid auctions.

A blog guide on "how to clean suede boots" might attract plenty of clicks at a low cost per click, which looks attractive to an automated traffic system. For the merchant, however, paying two dollars a click to send people to an article with no add-to-cart button or to a return policy page is pure wasted ad spend.

Why automated URL expansion picks informational pages

URL expansion systems look for text overlap between a user's search query and the indexed pages on your domain. Informational pages, FAQ hubs, sizing charts, and blog articles contain long blocks of natural-language text that match hundreds of broad questions. Product and collection pages, by contrast, are often concise and structured around SKU specs.

Without explicit URL exclusions, the algorithm matches informational queries to your blog or help center, rewrites the ad headline to match the article title, and bills your campaign budget for readers who have zero intention of buying today. Even worse, customers looking to return a past order can trigger paid ads that route directly to your /returns or /shipping-policy page, charging you for customer support navigation.

The mandatory URL exclusion list for ecommerce stores

Before launching any campaign that touches URL expansion, Dynamic Search Ads, or automated asset routing, build a permanent non-buyer URL exclusion rule set. At minimum, audit and block the following URL patterns across your storefront:

  • Editorial and content directories such as /blog/, /blogs/, /journal/, /news/, /recipes/, and /guides/.
  • Policy and legal pages including /policies/, /shipping, /returns, /refund-policy, /privacy-policy, and /terms-of-service.
  • Customer support and account utility paths such as /pages/faq, /pages/contact, /account, /cart, /checkout, and /track-order.
  • Company background pages like /pages/about-us, /careers, /press, and /sustainability unless specifically used in a dedicated brand sitelink.
  • Archive collections, gift-with-purchase hidden items, zero-dollar warranty SKUs, and wholesale login pages.

Auditing past spend in the Landing Pages report

Do not assume your current campaigns are clean just because you entered a collection URL at the ad group level. Open the Landing Pages report in Google Ads, filter by the last 90 days, and sort by cost. Then look for URLs containing /blog, /pages, or /policies.

Check both standard Search campaigns where AI Max or Final URL expansion may have been enabled and Performance Max campaigns where Final URL expansion defaults to on. If you want to know which campaigns are affected by recent platform shifts, read our guide on which Search campaigns actually face an AI Max upgrade and our breakdown of AI Max for Shopping.

How Kopa blocks non-shopping URLs at Stage 1

In Kopa, Smart Campaigns filters your domain during Stage 1 before any keyword or ad group is drafted. Blog posts, shipping pages, return policies, terms of service, and informational pages are automatically excluded from campaign target selection and added to URL exclusion rules so paid budget only routes to buyable product and collection pages.

What good looks like

  • Every Search, Dynamic Search, AI Max, and Performance Max campaign has explicit URL exclusions for /blog, /policies, /shipping, /returns, and /faq.
  • Final URL expansion is either turned off on tightly themed bottom-of-funnel Search campaigns or locked down with strict path exclusion rules.
  • Zero-dollar add-ons, replacement parts, and promotional free-gift SKUs are excluded from paid landing page eligibility.
  • The Google Ads Landing Pages report is audited monthly to verify that 100 percent of paid clicks land on pages with an active purchase path.
  • Informational blog articles are monetized through organic search and email capture rather than paid Search budget.
