Choose a Jersey marketing agency on four things: proof of measurable results, real knowledge of the local market, a clear measurement plan for your money, and how honestly they talk about what could go wrong. Portfolio polish matters far less than whether the agency can show, in numbers, what happened to the businesses they worked with.
1. Ask for numbers, not logos
A wall of client logos tells you who paid an invoice; it doesn't tell you what they got. Ask every agency the same question: “what did this cost per lead or per sale?” As a reference point, our Meta campaigns for a Jersey wealth management client delivered 150+ qualified leads at a £4.70 blended cost per lead, in financial services, one of the hardest categories to advertise in. Any serious agency should be able to quote its own equivalents.

2. Local knowledge is not optional here
Jersey is a market of roughly a hundred thousand people with its own regulators, seasons and sensibilities. Campaign mechanics that work in London (broad targeting, high-volume creative testing) behave differently in a small audience pool. An agency that works here should be able to talk specifically about frequency management, creative fatigue and what compliance-conscious sectors like finance can and cannot say in an ad.
3. Insist on a measurement plan before you sign
Before any work starts, you should know: what counts as a lead, where results will be tracked, and what you'll see in a report each month. If the answer is “engagement” and “reach” with no line to enquiries or revenue, keep looking. This is why we put a definition of a qualified lead in writing before launch.
4. Watch for the red flags
A few patterns reliably predict a disappointing engagement: guaranteed rankings or follower counts (nobody controls an algorithm, and bought followers are worse than none); contracts that lock you in for a year before any results exist; reporting that arrives as a screenshot with no access to the underlying ad account; and agencies that won't say who actually does the work. If the pitch team and the delivery team are different people, ask to meet the delivery team. None of these is disqualifying alone, but two together should slow you down.
5. Prefer a system over a shopping list
Social content, advertising and your website behave as one funnel whether anyone manages them that way or not. Agencies that run them as separate line items leak results in the gaps. Our answer is Cold Fusion: organic social, Meta ads and a conversion-focused website run as one system, guaranteed to produce 50 qualified leads in the first 90 days. Whoever you choose, favour the agency that explains how the pieces connect.
