Choosing a marketing partner is a bigger decision than picking a channel. These guides compare the main options, an in-house hire, a freelancer, a generalist agency, a specialist agency and Commerce Media Group, and list the questions to ask in your industry. Each one says when we are a good fit and when another option is better.

## How we evaluate marketing partners

1. **Industry rules.** Does the partner know the ad policies and regulations that apply to your industry, and show you how they shape the work?
2. **The path to a sale.** Can they build the whole route from ad to website to booked appointment, job or quote, rather than one piece of it?
3. **Follow-up.** What happens to a lead in the first minutes and days, and who is responsible for it?
4. **Measurement.** Do they report the numbers that map to revenue, such as cost per lead and return on ad spend, and tie leads to real sales?
5. **Who does the work.** Will you know the people running your account, and can they explain what they changed and why?
