So I've been asked to create goal funnels within google analytics which are identical except for the first url in the funnel. For example:
Step 1: Sales page #1
Step 2: Info page
Step 3: Checkout page
Destination goal: Thank you page
And the second funnel would be the same except Sales page #1 would be Sales page #2.
My question is because the destination goal is the same, if one funnel is generating more goal completions than the other, would it backfill up on the less successful funnel and cause the numbers to be identical?
