Reply To: How do you charge a client for PPC?

Most common is either a % of ad spend (usually 10–20%) or a flat monthly fee.

For smaller accounts, I prefer a flat retainer so it’s predictable for both sides.
For bigger budgets, % of spend makes more sense.

Sometimes I add a performance bonus tied to ROAS or CPA if goals are clear.
