Running controlled experiments on the pages that receive campaign traffic.
Samir Haddad
At a glance
- Requirement one page, one audience, one action
- Message match the page should echo the ad that delivered the visit
- Test scope one substantial change rather than many small ones
- Duration run full weekly cycles to avoid day-of-week effects
- Novelty effect returning visitors may react to change itself
Why it matters
Why it matters: Landing pages receive concentrated, measurable traffic with a single defined action, which makes them the best available testing environment.
Best practice
- Match the page message to the ad or email that brought the visit
- Test one substantial change at a time
- Run for complete weekly cycles
- Define the primary metric before starting
- Follow up wins with research into why they won
Common pitfalls
Watch out for:
- Sending paid traffic to the home page
- Testing many small changes simultaneously
- Ending tests mid-week
- Choosing the winning metric after seeing the results
When to call in a specialist
Bottom line Bring in help when paid traffic converts below account average, when tests never conclude, or when one page must serve several very different campaigns.
