How Many Solo Ad Clicks Should You Buy?

There is no universal number of solo ad clicks that every marketer should buy. The useful test size depends on your conversion event, budget and how much data you need before making another decision.

Start from the event you care about

If you only measure visits, almost any order provides data. If you want to compare cost per lead or customer acquisition cost, you need enough traffic for those downstream events to occur often enough to interpret.

Avoid false precision

Past conversion rates can help estimate a test size, but a new provider or audience can behave differently. Treat projections as planning assumptions, not guarantees.

Scale after evidence improves

Increase order size when the source, page and follow-up have produced economics you understand—not because the first campaign simply delivered its promised visitors.
