Eight questions. A good agency answers each one plainly, without needing to go away and check.
Ask for the answers to 3, 4 and 5 in writing. They are the ones that cost you money if they are vague.

Who runs your account. In a pitch you usually meet the most senior person in the room. Ask who will open your account on a normal Tuesday, make the changes and answer your messages. Then ask to speak to that person before you sign.
Results with dates. "We grew leads by a lot" means nothing without a month, a channel and a source. Ask for a dated example, and ask about a campaign that did not work. An agency that says it has never had a miss is either very new or not telling you everything.
What the fee covers. Get the list in writing: campaign management, creative, landing pages, tracking setup, reporting, calls. Anything outside the list should have its own price, so there are no surprises in month two.
How ad spend is paid. The cleanest setup is that you pay Meta and Google directly, from your own payment method, inside your own ad accounts. If spend goes through the agency, ask for the platform invoices every month and for any markup to be stated in writing.
Who owns the accounts. The ad accounts, the Meta pixel, Google Tag Manager, Google Analytics and the data in them should belong to your business. The agency works on them with access you give and can take back.
How leads are tracked. Ask what fires a conversion. A submitted form, a call or a booked appointment is a lead. A page view is not. Then ask whether they check the platform numbers against the enquiries your team actually received. Our Google Ads audit checklist shows what to look for.
Reporting. Agree on how often, and on what is in it. Spend, leads and cost per lead come first. If you sell online, add sales and revenue. A good report also says what changes next and why.
Minimum term. Paid ads need time to learn and a working rhythm to build, so a minimum term is not a red flag on its own. What matters is that the agency tells you the reason, and that the exit terms are written down.
