Questions to ask a Los Angeles agency

1. Which Los Angeles 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 Los Angeles businesses work well with agencies based elsewhere, since most work happens online. A local agency can meet in person and may know the Los Angeles 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.
