Using regex in Google Analytics to define a funnel

Question

I'm attempting to set up a funnel in GA based on the destination page being /m/thanks(.*) where there are multiple one-time-offer pages in between that add a additional parameters to the URI.

The desired goal is to measure a Free signup. The flow looks like this..

• Destination Page: /m/thanks?id=3LKJE-a723a72bc96cba65&oto=no&oto=no

The oto=no&oto=no signify that the user has declined both OTO pages, and therefore results in a free lead

• Step 1: Landing page: (literal URL)

• Step 2: Signup Page: (literal URL)

• Step 3: OTO 1: /m/thanks?id=3LKJE-a723a72bc96cba65

The string after ?id= is dynamically generated, but does not contain &oto=no

• Step 4: OTO 2: /m/thanks?id=3LKJE-a723a72bc96cba65&oto=no

Same id, but contains exactly one instance of &oto=no

---

I'm not sure the best way to represent step 3 and 4 to make sure I am recording only those pages.

Description

This regex will:

• validate the string does not have a &oto=no value
• captures the query string value for ID
• validates the string has /m/thanks?
• allow the querystring attributes to appear in any order

^(?!.*?&oto=no)(?=.*?[?&]id=([^&]*))\/m\/thanks(?=[?])

• ^ match the start of the string
• (?!.*?&oto=no) look ahead an validate we can't find a oto=no key value set
• (?=.*?[?&]id=([^&]*)) look ahead and validate we have the id and capture the value
• \/m\/thanks(?=[?]) ensure the string starts with /m/thanks?

OR

This regex will:

• validate you have 2 instances of oto=no in the string
• capture the ID value
• validates the string has /m/thanks?
• allow the querystring attributes to appear in any order

^(?=(?:.*?&oto=no){2})(?=.*?[?&]id=([^&]*))\/m\/thanks(?=[?])

• ^ match the start of the string
• (?=(?:.*?&oto=no){2}) validate that oto=no exists twice in the query string
• (?=.*?[?&]id=([^&]*)) capture the id value
• .*?(?=[?]) capture the string upto the first ?
