Web Design for Middlesbrough Businesses

Koseti is a Middlesbrough-based web design agency building websites for North East businesses that need more than a digital brochure, with GA4 analytics, conversion tracking, and a 30-day performance report built in from day one.

Koseti is a Middlesbrough-based web design agency building websites for North East businesses that need more than a digital brochure. Every site we build includes GA4 analytics, conversion tracking, and a 30-day performance report, so you know from the start whether it is working.

Most Middlesbrough websites are built to look good, not to work

The usual pattern goes like this: a local business pays £1,500 to £3,000 for a website, it goes live, it picks up a handful of visitors, and nobody really knows whether it is bringing in any enquiries, because nothing was ever set up to measure it. We see this regularly with businesses across Middlesbrough, Stockton, and Darlington.

Six months on, the owner is stuck. They cannot tell whether the site is worth keeping, worth spending more on, or quietly costing them work. With no figures to point to, every decision about the website is a guess.

We do it the other way round. Analytics goes in before launch, not as an afterthought, so by the time a Teesside business's site goes live we already know what "working" looks like for it. If you want a sense of what a website actually costs before you commit, we have set the real numbers out plainly.

What you get with Koseti in Middlesbrough

Analytics built in, not bolted on

GA4 configured properly, conversion goals defined, and a baseline traffic report delivered 30 days after launch. You'll know exactly how many people visited, where they came from, and what they did.

Built to generate enquiries

Every page is structured to guide visitors towards an action: a phone call, a form submission, or a quote request. Design decisions are made with that goal in mind, not just how it looks.

The right platform for your business

We build in Laravel for businesses that need custom functionality, and WordPress for those that need simplicity and easy content management. We will tell you which is right before we start.

We don't disappear after launch

Hosting, backups, updates, and someone to call when something needs changing. We work with Middlesbrough businesses on an ongoing basis, not just a one-off project basis.

Why work with a Middlesbrough agency?

There is a practical advantage to working with someone in the same town. We can meet at your premises or ours, there is no timezone to work around, and there is no account manager relaying messages, so you speak directly to the person building your site. For a Middlesbrough business, that usually means a decision gets made in a single conversation rather than a week of emails.

We also know the local market. We understand what Teesside businesses are actually spending on websites (not London rates), what the competition looks like across the area, and what a North East SME audience responds to. We are based in Middlesbrough and work with businesses across Teesside, including Stockton, Darlington and Hartlepool, as well as clients further afield. For more on what North East businesses should expect from a web designer, we have written it up.

Common questions

Web design in Middlesbrough typically ranges from £800 for a simple brochure site to £5,000+ for a custom-built site with e-commerce or bespoke functionality. At Koseti, most small business projects fall between £1,500 and £3,500 depending on the number of pages, features required, and whether the site needs a CMS. We give fixed quotes, with no hourly billing surprises. Read more on what a website actually costs in 2026.
A standard small business website takes 4 to 6 weeks from briefing to launch. E-commerce or custom Laravel builds typically take 8 to 12 weeks. We work to agreed milestones and keep you updated throughout, so you won't be chasing us for progress reports.
Yes. While we're based in Middlesbrough, we work with businesses across Teesside, the wider North East, and nationally. Most of our process works remotely, with the option for in-person meetings for local clients.
Every site we build is mobile-first, designed and tested on phone screens before desktop. More than half of local business searches in the North East happen on mobile, so this isn't optional.
We deliver a 30-day performance report showing traffic, top pages, and any early conversion data. After that, we offer monthly retainers covering hosting, updates, and ongoing analytics review, or we can hand everything over to you if you prefer full control.
