Questions
Choosing a Google Ads agency in Nantes.
How much does a Google Ads agency cost in Nantes?+
A flat monthly fee or a percentage of ad spend, depending on the size of the account and what is included. Ad spend is paid to Google on top. Ask for the fee in writing and check whether it grows when your budget grows.
Agency or freelance consultant?+
A freelance consultant can be cheaper and very hands-on, but nobody watches the account during holidays. An agency gives continuity. Either way, ask who works on your account each week.
Should I target Nantes only or the whole Loire-Atlantique?+
Start with the zone you really serve. Many Nantes businesses also sell to Saint-Nazaire and the coast; widen the targeting only if the cost per lead stays under control.
