How to Choose an Agency or Developer for Your Website

Most companies buy a website once every five years, with no yardstick for what good looks like. This guide is the yardstick. We wrote it honestly, even where the answer is "you may not need us."

Agency or freelancer: what is the difference, and which should you pick?

Neither is right or wrong. They are two different risk profiles.

• A freelancer usually costs less and moves faster on smaller projects, and you talk to the person doing the work. The risk: one person is a bottleneck. If they fall ill, leave or go quiet, the project stalls. Few cover SEO, security and maintenance in one place.
• An agency has more people, processes and, as a rule, continuity. The risk: higher prices, slower pace, and you often become one row in a client list. Some agencies hire the same freelancers for the actual build anyway.

The middle option, and often the best one for a small business: a small, specialised provider. Personal like a freelancer, but with a real company, real invoices and responsibility for the result. That is us: Segentic stands behind a registered Slovenian company, and one person you can reach by phone does the work.

What should I watch for when choosing a developer?

Five things separate a professional from someone who "also does websites":

1. They show speed, not just looks. Ask for the PageSpeed or Lighthouse score of their existing sites. If they dodge, you know enough. (This site scores 100/100 and loads in under half a second. Check for yourself.)
2. They can tell you what you do not need. Someone who sells you the biggest package on the first call is selling to themselves, not solving your problem.
3. Clear ownership. Ask directly: who owns the domain, hosting, code and content after handover? With us, everything is yours, source code included.
4. A fixed price, not a "from–to" range. A serious provider can scope the work up front.
5. Responsiveness during the sales phase. Someone who answers slowly while trying to win you will not get faster once you are a client.

How do I pick the right agency to build my website?

A three-step process that removes the guesswork:

1. Narrow the field to 2–3 candidates based on references in your industry or at your size.
2. Ask for a concrete quote with scope: what is included, what is not, by when and at what price. Compare scope, not just price.
3. Test one of their existing sites yourself: speed (PageSpeed), how it works on a phone, and whether it works at all. Marketing can lie. A measurement cannot.

Red flag: a provider who asks nothing about your business. Someone who does not ask builds for everyone, which means for no one.

How do I check whether an agency is reliable and experienced?

Reliability is proven with evidence you can verify, not with the phrase "10 years of experience":

• A registered company that issues invoices. A Slovenian s.p. (sole trader) or d.o.o. (limited company) with a valid matična številka (company registration number) and davčna številka (tax number) means accountability and a real invoice, not an anonymous platform.
• Live references, not screenshots. Ask for links to actual sites and open them.
• A verifiable track record. A public profile (GitHub, portfolio, case studies with numbers). Our example: a rebuild that made the site 4× faster and cut the annual cost from €350 to €12.
• Willingness to start small. A provider who offers a smaller, limited first scope is not running from measurability.

What should I ask an agency before signing the contract?

Seven questions that save you the most trouble. Ask all of them before you sign:

1. What exactly does the price include, and what costs extra?
2. Who owns the domain, hosting, code and content after handover?
3. What are the monthly costs: hosting, licences, maintenance?
4. What happens if I want to move to another provider in a year?
5. Who fixes the site if it stops working after launch, and how quickly?
6. How fast will the site you deliver be (a concrete measurement)?
7. Who will do the actual work, and can I reach them directly?

If a provider answers any of these vaguely, that is a pattern, not a detail.

How do I check the quality of an agency's work before committing?

You do not have to take quality on faith. Measure it in five minutes on one of their existing references:

• Speed: enter their site at pagespeed.web.dev. Green scores (90+) mean they know what they are doing. Red scores mean your site will look the same.
• Mobile: open the site on your phone. Does it load fast, read well, work?
• SEO basics: do the pages have sensible titles, descriptions and structure? You can see this in Google's listing already.
• Details: working links, forms, no intrusive pop-ups. Small things reveal care.

If a provider's reference fails these five minutes, your site will not be better. It will be the same.

When you may not need an agency at all

Honest to the end: if you need one simple page with basic information and no maintenance, you may be better off with a do-it-yourself tool or a smaller provider at a fixed price. An agency makes sense when you need reliability, speed, SEO and someone who answers for the result, for years rather than only until launch.
