Decide from behavior
A smaller source producing relevant actions can be more useful than a large source producing only short visits.
Frequently asked questions
Is the cheapest click the best click?
Not necessarily. Relevance and meaningful actions matter more than price alone.
Can one test prove a source works?
No. A small test provides evidence for the next decision, not permanent proof.
A responsible next step
Use this guide to identify one action you can complete and document. Avoid changing everything at once. A small test with clear records usually teaches more than a large campaign built on assumptions.
