如何用带例外的Regex配置GA URI搜索替换过滤器合并注册路径

Hey there, let's work through this Google Analytics filter setup to clean up your enrollment path tracking. I've got a tailored solution that'll merge all those messy variants into a single /enrollment path while excluding your thank-you pages—here's how to do it:

Your goal is to collapse 4000+ enrollment-related path variants (like /enrollment, /enrollment/, /enrollment/sem01, etc.) into a unified /enrollment value, while excluding any thank-you pages that fall under the /enrollment namespace. We'll use a custom search-and-replace filter with a regex that includes an exclusion rule to make this happen.

Here's the exact regex and replacement value you'll need:

Search String (Regex) #

^\/enrollment(?!\/thank-you)(\/.*)?$

Replace String #

/enrollment

Adjusting the Exclusion Rule #

If your thank-you page uses a different path (e.g., /enrollment/thanks, /enrollment/confirmation), modify the negative lookahead part to match. For multiple excluded paths, use a pipe | to separate them:

^\/enrollment(?!\/thank-you|\/thanks|\/confirmation)(\/.*)?$

1. Log into your Google Analytics account and navigate to the custom view you created for this tracking.
2. Click the Admin gear icon in the bottom-left corner.
3. In the View column, select Filters.
4. Click Add Filter to create a new filter.
5. Give your filter a descriptive name (e.g., "Merge Enrollment Paths & Exclude Thank You").
6. Under Filter Type, select Custom, then choose Search and Replace.
7. From the Field A -> Extract A dropdown, select Request URI (for GA4, select Page path + query string instead).
8. Paste the regex from above into the Search String field.
9. Paste /enrollment into the Replace String field.
10. Use the Filter Test section at the bottom to verify:
    • Input paths like /enrollment or /enrollment/sem01 should show a replacement value of /enrollment.
    • Input your thank-you page path (e.g., /enrollment/thank-you) should not be matched or replaced.
11. Click Save to activate the filter.

Let's break down the regex so you understand how it works:

• ^\/enrollment: Matches any URI that starts with /enrollment (the ^ ensures we only match the start of the string, and \/ escapes the forward slash for regex syntax).
• (?!\/thank-you): A negative lookahead that tells the regex to skip any path where /enrollment is immediately followed by /thank-you—this excludes your thank-you pages.
• (\/.*)?: Matches any optional trailing content after /enrollment (including a trailing slash or SEM/UTM parameters). The ? makes this section optional, so it covers both /enrollment and /enrollment/ cases.
