How to choose a digital marketing agency in the US

A digital marketing agency, on this list, runs search, paid media, email and analytics as one program. The point of one firm is a single plan, not four logins and a monthly PDF that nobody owns.

The fit is bad when you only need one channel. Pay a specialist for that. The fit is good when the channels have to agree with each other and someone has to decide what to stop.

Write these down before you talk to a digital marketing agency. A vague brief produces a vague price.

• Name the one number you want moved, and the channels you believe affect it.
• Say what is already running, including in-house work and other agencies.
• Separate management fees from media spend in the brief.
• Decide who inside your company can change the site, the offer and the tracking.

Ask each firm the same list. The useful part is the difference in the answers, not a polished version of the question.

• Which channel would you refuse if it did not fit this business?
• Who owns the analytics, and what is broken in the current tracking?
• How do you decide that a channel is not working, and how fast do you stop it?
• What is the fee, what is the media, and what production is extra?
• What does the monthly report change about next month's work?

This is a short list of digital marketing agencies that do the work at a national scale. It is not a directory of every firm in the United States. State and city pages show where the listed firms are based, and only where the list has enough firms to say something.

Hiring across states is normal for this work. Ask which time zone the account runs on, who attends your meetings, and where the people doing the work sit.

In the list's order: Merkle, iProspect, Performics, iCrossing, Jellyfish, Rise, PMG, Power Digital, Seer Interactive, WebFX, NP Digital, Ignite Visibility, Directive, Thrive Internet Marketing Agency.

Write the job in one paragraph. Keep the two or three firms whose reason for being here matches that job.

Open each profile. It says who leads the firm, work they can show, and a price if they published one. If they did not publish a price, the profile shows a typical estimate and says it is not a quote.

Then ask each firm for one piece of work like yours, and the name of the person who would do it.

The order weighs how long the firm has done the work, clients it can name, its size, and how clear its specialism is. Nobody pays to be ranked.

One card is marked Featured. It is paid placement for Fracs, which shares this list's publisher. It sits outside the ranking.

If a profile leaves out a leader, a price, or a founding year, no source stated it.
