One-page website: what it is, what it costs and when it's worth it

The definition is easy. The real question is whether your business fits on one page. My position: most small service businesses do, and plenty of owners pay for an eight-page site where nobody gets past the homepage.

What goes on a one-page website

A good one-page site is not a long page full of decoration. It's a sequence built to take someone from "what is this?" to "let me message them." The order I use:

1. Hero with the promise. One sentence on what you do and who it's for. Contact button right there.
2. The problem you solve. Two or three lines in your customer's words, not your industry's.
3. How it works. The steps, from first contact to delivery.
4. Proof. Real photos, Google reviews, before and after shots, licenses. Whatever you actually have.
5. Price or terms. A number, a range or "starting at." Hiding everything pushes away the people who are ready to buy.
6. FAQ. The questions you already answer over and over by text or email.
7. Contact. The button again, plus address and map if you have a physical location.

The contact button shows up several times and ideally sticks to the bottom of the phone screen. People coming from Instagram or a Google ad are on mobile. If they have to hunt for a way to reach you, they leave. In the US that button might be call or text. In much of Europe and Latin America, WhatsApp is what people actually use, and it's what I build in by default.

How much a one-page website costs

There's no official price list. As a broad estimate, a one-page site usually lands somewhere between a few hundred and several thousand dollars. At the low end you're typically getting a template with your text swapped in. At the high end you're paying for brand work, custom photography or integrations.

What moves the price:

• Copy. If you hand over finished text, it's cheaper. If someone writes it to sell, it costs more and usually earns more.
• Languages. A vacation rental in Lisbon or a dental office in Miami may need a second language done properly, not pasted from a machine translator.
• Ad readiness. Meta Pixel, Google tag, click tracking on the contact button. Without that, you pay for ads and can't tell what worked.
• Speed. A light page loads fast on mobile data. A heavy one loses people before it finishes loading.
• Ongoing costs. Domain and hosting renew every year or month. Ask who pays and whose name the domain is registered in.

At 27LAB, the sites that sell are exactly this: one page with a WhatsApp button, ready for ads, in English, Spanish or Portuguese, starting at US$ 1,500. You see a working preview before you pay anything. If it doesn't make sense, you walk away.

When a one-page site is worth it

It's worth it when the customer's path is short: see, trust, reach out. A few cases where I'd go one page without a second thought:

Bed and breakfast or vacation rental

Guests want rooms, location, breakfast and how to book. One page with good photos, a map, a nightly rate range and a contact button handles it. Add a second language and you also serve international travelers who'd rather book direct than through a big platform.

Dental, physio or wellness clinic

Patients want to know what you treat, where you are, which insurance you take and how to book. One page with services, team, credentials and a booking button.

Real estate agent

For a single listing or a new development, a dedicated page beats sending buyers to a crowded listing portal next to your competitors. Floor plans, neighborhood, pricing, contact.

Restaurant or food truck

Short menu, hours, location, order link. Nobody clicks through five pages to order tacos.

The common thread: one main offer, one action you want people to take, and an audience arriving on a phone.

When it's not worth it

I'm a fan of one-page sites, but they have limits. I wouldn't recommend one when:

• You have a large catalog. A store with 200 products needs an actual online store with cart, filters and inventory.
• You rely on organic search across many topics. A law firm that wants to rank for ten practice areas needs a page per area, plus content.
• You sell very different things to very different people. Cramming it all onto one page confuses everyone. Build one page per offer instead.
• You need a client area. Logins, integrated scheduling, portals: that's software, not a website.

A sensible path is to launch a one-page site for your main offer and add pages as the business asks for them. Your site doesn't need to be born big.

Why one-page sites and paid ads work together

Someone who clicks an ad arrives with one specific intention. If they land on a homepage with a seven-item menu, they get lost. If they land on a page that talks about exactly what the ad promised, with the contact button in view, they're more likely to reach out.

One page also makes measurement simple. You know how many people arrived, how many tapped the button and which ad sent them. That's what lets you adjust the budget afterward. When I run paid ads for a client (pricing on request outside Brazil), I'd much rather send traffic to a page like this than to an Instagram profile or an old brochure-style site.

What I'd check before hiring anyone

Before you sign with anyone, including me:

• Can you see a preview or real examples working on a phone?
• Is the domain registered in your name?
• Who writes the copy, and does it sell or just describe the company?
• Does the contact button open with a prefilled message?
• Is the page ready for a pixel and ad tags?
• What does it cost to change a price or swap a photo later?
• Does it load fast on mobile data? Test it yourself, off Wi-Fi.

If half the answers are "we'll figure that out later," be careful.

Next step

If your business fits on one page and you want to see what yours would look like, message me on WhatsApp. You get the preview before you pay. If you'd rather watch first, I'm on Instagram at @bnd.g and on LinkedIn as Bernardo Garcia.
