Choosing a web design agency is one of the most important decisions you'll make for your business online. The wrong choice costs time, money and customers. The right one gives you a website that works for you for years. This guide shows you exactly what to look for in the Oslo market — the criteria that matter, the questions to ask, and the red flags to walk away from.
Look at the work, not just the words
Every agency says they build "modern, converting websites" — the proof is in the portfolio. Look for real, live sites you can actually visit, not just pretty mockups. Open them on your phone: do they load in under a second? Can the agency point to measurable results — more enquiries, sales or bookings — and have they worked with businesses like yours?
A portfolio of live, fast, relevant work tells you far more than any sales deck. If an agency can't show you sites you can open and click through, treat that as your first warning sign.
Demand speed and technical quality
A beautiful site that loads slowly loses both customers and Google ranking. Ask directly what their sites score on Google Lighthouse (performance, accessibility, SEO), and whether they build mobile-first. Ask what they build with, too: heavy WordPress themes and plugins tend to be slower and more fragile than custom, modern code.
Speed and clean code aren't technical trivia — they decide whether visitors stay, whether Google ranks you, and how easy the site is to maintain and grow over the years that follow.
"Ask for the Lighthouse score. A site that isn't fast and accessible is losing you customers before anyone reads a word."
Check SEO, ownership and hosting
A website nobody finds is wasted. A good agency builds on-site SEO in from the start — the right structure, headings, metadata and local content — not as an expensive add-on later. Make sure it's part of the core delivery, not a line item you discover afterwards.
Then settle ownership before you sign: do you fully own the site and its content? Do they offer hosting and maintenance after launch? And if you ever part ways, can you take everything with you, or are you locked into their platform? The right answers protect you long after launch.
Weigh size, closeness — and the red flags
Big agencies have famous clients, but you can become a small number in the queue. A small, local Oslo team often works more closely with you, knows the market and responds faster. Choose the people who'll actually work on your project, not just the salesperson you meet first.
Walk away from these red flags: no live portfolio (only mockups), vague pricing and unclear deliverables, no mention of speed, SEO or accessibility, lock-in to their platform, and slow communication even during the sales stage. How they treat you now is how they'll treat you later.
The questions to ask — and what it should cost
In the first meeting, ask: Can I see three live sites you've built? What do they score on Lighthouse? Is on-site SEO included? Who owns the site and content afterwards? Do you offer hosting and support? What's the timeline and the price? Clear answers signal a partner; vague ones signal trouble. On cost: simple business sites are lower, online stores and web apps cost more — but always insist on a fixed quote based on your goals, never an open-ended bill.
That's exactly how WEBRISE works: a small Oslo team building fast, custom-coded sites with on-site SEO and hosting included, aiming for Lighthouse 100 on every page — and you own everything. You get a partner, not just a vendor. Reach out for a free quote and let's scope your project together.
