SOP: A/B a prelander inside the smartlink, not the offer

A smartlink sent cold traffic straight to a sweeps offer at $0.18 EPC. We tested adding a prelander as a routing branch.

Steps run:
— Step 1: Split traffic 50/50 at the smartlink: branch A direct-to-offer, branch B prelander-then-offer.
— Step 2: Hold 5,000 clicks per branch, same offer downstream.
— Step 3: Branch A EPC $0.18, branch B (prelander) EPC $0.25.
— Step 4: Promote prelander to 100%, keep 10% direct as ongoing control.

Outcome over 12 days: blended EPC rose from $0.18 to $0.24 (+33%). The prelander pre-qualified clicks, so the offer's own conversion rate rose from 1.0% to 1.4%.

Repeat per new geo: prelanders that win in one country can lose in another — re-split before assuming it carries over.
