How to choose a digital marketing agency?

Q: Who owns the ad accounts and website, me or the agency?

Always you. This is non-negotiable. You must own the Google Ads account, the social profiles, the website, the content and the data. The agency works with admin access, never as the owner. If they build everything inside their own accounts and you leave with nothing, you are held hostage. Demand in writing that all assets and history stay in your name, even after the contract ends. No ownership, no signature.

To choose a digital marketing agency, demand full ownership of your accounts, ask for documented case studies with real numbers from similar businesses, learn who will actually execute, and get a clear first-30-days plan. Walk away from anyone promising guaranteed results or locking you into a no-exit contract.

This guide gives you a question checklist to bring to your next meeting and tell real process from empty promises.

What questions should I ask a marketing agency before hiring?

Bring this checklist to the meeting. Write down the answers and compare proposals:

Will the Google Ads, Meta and website accounts be in my name?
Who will execute my account day to day?
Can I see case studies from similar businesses with real numbers?
How do you define and report success, and how often?
What is the first-30-days plan, week by week?
What are you specialists in, or do you do everything?
How does exiting the contract work?
Which KPIs will we track together?

Who will actually work on my account?

Ask directly and get names. It is common for the founder or a senior to shine in the pitch, and once you sign your account lands with a junior. Find out who you email every week, who makes the campaign decisions and how experienced that person is. Ask to meet the executor before you commit. If the agency dodges the question or promises a vague team with no names, treat it as a red flag.

Who owns the ad accounts and website, me or the agency?

Always you. This is non-negotiable. You must own the Google Ads account, the social profiles, the website, the content and the data. The agency works with admin access, never as the owner. If they build everything inside their own accounts and you leave with nothing, you are held hostage. Demand in writing that all assets and history stay in your name, even after the contract ends. No ownership, no signature.

How do I verify an agency's real case studies?

Ask for documented case studies, not a wall of logos. A pretty logo proves nothing about the work delivered. Demand:

Real numbers: spend, return, cost per lead or sale
Timelines: how long the result took to show
Context: businesses your size or in your sector
References: clients you can actually talk to

If they only show screenshots with no context or refuse to give references, be suspicious.

Should I hire a specialist or a full-service agency?

It depends on your need. A specialist delivers more depth in one channel, ideal when the problem is clear, like paid ads or SEO. A full-service agency gives cross-channel coordination and a single point of contact, useful when you need integrated strategy. The generalist risk is being shallow at everything; the specialist risk is missing the bigger picture. Ask what they are genuinely strong at and what they outsource, then decide by your main bottleneck.
