Companies in Seattle usually have engineers and no marketing process
The characteristic buyer here is a technically strong business with a product people like and no repeatable way of putting it in front of strangers. There is often analytics data of good quality, a team that can build anything asked of it, and nobody whose job is to decide what should be built for marketing purposes.
That changes what is worth buying. Hiring an agency to do everything wastes the internal capability you already have. Hiring one to do nothing but run adverts leaves the harder problem untouched. The useful purchase is usually narrow and senior: someone to decide the sequence, define what should be measured, write the messaging, and then use your own engineering team for implementation. Say this in the brief, because most digital marketing proposals arrive assuming the client has no technical resource at all and will price accordingly.
Product-led businesses buy a narrower kind of digital marketing
If people can sign up without speaking to anyone, the agency's influence ends at the first session. Everything after that, whether the product explains itself, whether the empty state is useful, whether the second visit happens, is product work that no external campaign can fix.
Be explicit about that boundary, since a great deal of money is lost by paying for traffic that lands on a product not ready to receive it. Ask a prospective partner what they would refuse to be measured on, and listen for whether they understand the difference between acquisition and activation. An honest team will tell you that improving signup volume is their job and improving what happens after signup is yours. A team that promises to move retention through advertising is selling something that does not exist.
Subscription economics change what a good campaign looks like
Where revenue arrives monthly rather than at once, the first transaction is a poor way to judge a channel. A campaign that produces cheap signups from people who cancel in the second month is more expensive than one producing costly signups who stay for years, and no dashboard will tell you this within the reporting period.
Fix the measurement before the money starts moving. Agree that channels are judged on retained revenue over a defined horizon, not on first-month conversions. Agree who joins campaign data to your billing records and how often, since this is usually an engineering task and it needs to be scheduled rather than hoped for. Then agree an interim signal that correlates with retention, because you cannot wait a year to make a decision. Digital marketing in subscription businesses is mostly the discipline of resisting the fastest-moving number in the room.
First-party data is now the real constraint on measurement
Digital marketing measurement has become progressively less reliable through browser restrictions, operating system controls and consent requirements, and the effect is not evenly spread: some of your best audiences are the least measurable. Any supplier who presents platform-reported conversions as complete truth has either not noticed or is hoping you have not.
Ask how they handle it in practice. Server-side event collection, consented first-party identifiers, and conversion data sent back from your own systems are the standard answers, and they all require engineering work you will be doing rather than buying. Ask who specifies that work and who verifies it. Ask what share of conversions they expect to remain unobserved and how they plan to account for them. Then ask how they would test whether a channel contributes anything at all, since the only honest answer to unobservable data is to switch something off occasionally and watch what happens.
Agency, contractor, or a fractional marketing lead
Three arrangements compete for the same digital marketing budget here and they suit different stages. An agency brings a team, process and coverage across several disciplines, at the cost of overhead and a layer of account management between you and the practitioner. An individual contractor brings depth in one skill at a good rate, with no cover when they are unavailable and no breadth. A fractional lead brings judgement and direction for a couple of days a week and does very little of the execution.
The common mistake is buying execution when the missing piece is direction. If nobody internally can decide what should happen next, adding hands produces activity rather than progress. Work out which of the three gaps you actually have before you compare prices, because the three models cannot be compared on a rate card.
Fees, scope and the work that sits outside it
Price the digital marketing simply. Ask for a flat monthly fee tied to a defined scope rather than a percentage of media budget, since a share of spending rewards spending more. Keep platform billing on your own company card so costs arrive without markup. Then get a written list of what triggers additional billing: creative production, landing pages, analytics implementation, feed work and reporting are all commonly outside the fee and commonly assumed to be inside it.
If your engineering team is doing the implementation, negotiate the fee down accordingly and write the division of labour into the scope. Specify who writes the measurement specification, who builds it, who tests it and who signs it off. Ambiguity here is the most common reason a digital marketing engagement stalls in its first months with everyone waiting for someone else.
What you own once the engagement ends
A digital marketing engagement leaves behind accounts and configuration you will still need years later. Advertising accounts, analytics property and tag container belong under an asset container owned by your company, with the agency added as a user. Creative should be delivered as source files. Audience definitions, keyword sets, measurement specifications and any documentation written about your account should be exportable on request rather than surrendered at the end.
Read the notice period alongside the renewal clause, and ask what a handover looks like in practice. In technically sophisticated accounts the documentation is most of the value, so ask to see the running log of what was tested and what failed, and ask where it lives. If the scope includes substantial engineering work rather than campaign management, it is worth pricing that separately against software companies in this city.
Comparing a shortlist without being sold to
Send one document to every candidate: what the product does, who it is for, the commercial outcome, your internal engineering capacity, the separation between fee and media, the measurement approach you expect, and the decision date. Ask each to reply in that order.
Then ask two questions that sort experienced teams from confident ones. What would you stop doing that we currently pay for? And what result in the first quarter would tell you that your own recommendation was wrong? Reduce each proposal to four lines: agency fee, platform spending, monthly output, and what you keep on exit. You can browse the wider directory of digital marketing agencies by market, compare how the same brief is answered in a very different commercial culture such as Hamburg, and request proposals from several teams at once.
