There is no best digital marketing agency, only a best fit

Agencies with a verified published price

How to find the best agency for your situation

1. Define the job before you compare firms. Write down the one outcome that would make the engagement worth renewing, then the channel you believe drives it. An agency chosen against a written brief can be compared on scope. An agency chosen against a vague ambition will be compared on charisma.
2. Filter on published evidence first. Start with the firms that print a starting price, disclose a minimum engagement or name clients on their own site. This is not a quality judgement, it is a time filter: it removes the candidates whose first three answers would otherwise take a month of calls to obtain.
3. Use Google's own hiring questions. Google suggests asking for examples of previous work, what results are expected and in what timeframe, how success is measured, and how the agency will communicate. It also says to check business references with past clients, which almost nobody does and which reliably changes shortlists.
4. Run a small paid pilot first. Buy one defined piece of work at a fair price: a technical audit, a landing page, a single campaign build. How a firm handles a small engagement, its questions, its deadlines, its writing, predicts the large one far better than a pitch meeting does.

Why rankings of agencies are usually worthless

Most published lists of the best agencies are paid placements, affiliate arrangements or self-nominated awards, and the ones that are not are generally ranked on criteria with no bearing on your situation, such as headcount or years in business. A firm of two hundred people with a global client roster is not automatically a better choice for a nine-person company than a specialist of twelve. It is often a worse one, because your account will be staffed accordingly.

The alternative is not a better ranking, it is a different question. Instead of asking who is best, ask who publishes enough to be checked, who has done this specific job for a company like mine, and who will put scope in writing. Those three filters cut a field of thousands down to a handful, and every step can be verified without a meeting.

What separates a good agency from a good pitch

Good agencies ask uncomfortable questions early. Google's own guidance notes that a competent search professional should be asking what makes your business unique, who your competitors are and how customers find you, and advises finding someone else if they are not interested in your business. In practice the strongest signal in a first call is the ratio of questions asked to claims made.

The second separator is what happens when something does not work. Ask each finalist to describe a campaign that failed, what they changed and what they told the client. A firm with no such story has either not run enough programmes or is not going to tell you the truth when yours has a bad quarter.

Questions people actually ask

Is a bigger agency better?

Not inherently, and often the reverse for smaller budgets. What matters is who does your work day to day. Ask to meet the people who will be on the account rather than the people who pitch, and ask how many other clients each of them carries.

What should I be suspicious of?

Google names several warning signs directly: guaranteed number one rankings, claims of a special relationship with Google, priority submission offers, secrecy about methods, and unsolicited email from firms you never contacted. Any one of them is enough to end the conversation.

Retainer or project?

Project work suits a defined deliverable such as a site build or an audit. Retainers suit ongoing work such as content and paid media, where consistency compounds. If you are unsure, start with a project and convert it, rather than signing a year to find out.

How much of the fee should go to media?

It depends on the channel, but insist on seeing the split. A single blended number hides whether you are paying for expertise or for ad inventory, and a fee expressed as a share of ad spend rewards the agency for spending more of your money.
