Questions to ask a Denver agency

1. Which Denver businesses like mine have you worked with, and what changed for them?
2. Will you build or improve the landing pages your ads send people to, or only run the ads?
3. How will you track calls and forms, and can I see a test before we spend?
4. Will I own the ad accounts, website and analytics, with administrator access?
5. What will the monthly report show, and who explains it?

Local or remote?

Many Denver businesses work well with agencies based elsewhere, since most work happens online. A local agency can meet in person and may know the Denver market by heart. A remote one may offer more choice or lower cost. Judge both on results, reporting and ownership of your accounts, not on location alone.

Before you sign

Use the ad readiness check on the page you would send ad clicks to. Fixing the page first makes any agency's work go further.
