FAQ - Frequently asked questions about choosing a PPC agency

It depends on the industry and CPC. As a guideline, the budget should allow 50-100 clicks per key segment to draw initial conclusions. Important is hypothetical budget, not a „magic” amount.

First signs appear in 2-4 weeks; stabilization and serious optimization in 6-12 weeks, especially if you switch to tROAS/tCPA and feed the algorithms with clean conversions.
