Before you hire an agency, ask these important questions:

Tell me about the specific results you achieve for clients in my industry.
How will you prepare my site for the new AI-powered search features?
What methods do you use to measure success outside of just search ranking?
How often do we talk, and who is the person who works directly with me?

You want a partner who clearly explains their work and makes sure their ethical standards match yours.
