What should you tell a marketing agency before it starts?

Before any work starts, give the agency a one-page brief: what you sell and to whom, the areas you serve, what a typical customer is worth to you, what has worked and what has not, where inquiries come from today, what you will and will not do yourself, and who approves work. A clear brief can save weeks of guessing, and it gives both sides something to judge the work against later.

The one-page brief

One page in plain words is usually enough; update it when the business changes. The related answer on what a customer is worth shows how to work out the value of a job.

What a good agency will ask anyway

Google's guide "Do you need an SEO?" says to see whether an SEO is interested in you and your business, and that "Your SEO should ask questions about what makes your business unique", who your competitors are, how search results can help and how your customers find you.

As general advice, a written brief answers most of that before the first call. Name your main competitors, and say what customers tell you sets you apart.

Access and ownership come first

Give access, not passwords: add the agency as a user on accounts that stay in the business's name. The related answers on who should own your domain name and who should own your ad accounts explain why and how.

The related answer on what to have before starting SEO covers the rest of the setup, and the related answer on questions to ask before hiring an SEO agency covers checking the agency itself. The brief is the handover between the two.

Agree how the work will be judged

Put these in writing next to the brief:

  • The few numbers you will both watch, starting with inquiries by source and whether each was won, lost or still open.
  • What the agency must show you before anything is published in your name.
  • How often you will hear from it, and who your contact is.
  • What it needs from you each month, and by when.
