Start with their thinking, not just their portfolio.

Any agency can show you beautiful work. What matters is whether they can explain why decisions were made — how strategy shaped the design, what problem was being solved, and who the audience was. If the conversation is all aesthetics and no reasoning, look elsewhere.

Look carefully at who they’ve actually worked with. A surprisingly common pattern in the industry is an agency website that looks exceptional — often because it’s built on one of the premium agency templates — but whose portfolio, on closer inspection, is thin. Unknown brands, very small businesses, or work that doesn’t hold up beyond the hero image. The agency’s own website is not their work. Their clients’ websites are. Dig into those, look at the real businesses behind them, and ask yourself whether the outcomes are credible.

We hear a version of the same story regularly. A business comes to us having already spent significant money — sometimes with two or three agencies before us — with little to show for it. A website that never launched. A brand identity that never felt right. A process that lost momentum and quietly died. It’s more common than the industry would like to admit, and the financial and emotional cost is real. The due diligence you do before appointing an agency is the most important investment you’ll make in the project.

Be particularly cautious of SEO agencies that also offer branding and design — often with offshore production teams handling the creative work. These are very different disciplines requiring very different skills, and the combination rarely produces anything beyond the generic. If brand and design aren’t genuinely at the core of what a studio does, the results will reflect that.

Beyond that, look for relevant experience, a clearly defined process, and honest communication about what your budget can realistically achieve. The studios worth working with will tell you directly if the gap between expectations and investment can’t be bridged — and will walk away if it can’t. That candour at the outset is one of the most reliable signals of a trustworthy partner.

Fit matters as much as capability. The best agency relationships feel less like a transaction and more like a collaboration between people who respect each other’s expertise. Look for a studio whose work you genuinely admire, whose process makes sense to you, and whose principals you’d be comfortable having a difficult conversation with — because at some point, you will.

The right agency isn’t always the biggest, the cheapest, or the most awarded. It’s the one that understands your business, is honest about what they can deliver, and makes you feel confident that the project is in good hands. Do your research — the cost of getting this wrong is real.
