Last month I reviewed over 40 business card websites of small companies from the Tri-City area. Plumbers, transport companies, clinics, workshops, law firms. Most of them make the same 3-4 mistakes. And those mistakes cost them clients they don't even know about.

Every business card website must have these elements. Not "it would be nice" - it must. If any of them is missing, the website isn't working at 100%.

A headline that says what you do

You have 3 seconds. That's how long the average visitor gives you before deciding to stay or hit the back button. If the first thing they see is "Welcome to our website" - they leave.

The headline must answer one question: what does this company do and for whom. "Container transport from Gdansk across Europe" - clear. "Comprehensive logistics solutions" - unclear (and sounds like it was written by a robot).

Below the headline: one sentence of elaboration and a call-to-action button. "Send an inquiry," "Call now," "Check pricing." Not three buttons. One. The most important one.

Contact details - visible immediately

This is the number one mistake on the websites I reviewed. Phone number hidden somewhere at the bottom of the page, tucked away in the footer in small font. Email address requires scrolling 5 screens down.

Phone and email should be in two places: in the header (at the top, visible without scrolling) and in a contact section at the bottom. On mobile - the number should be tappable to call instantly. This isn't optional, it's a necessity.

If you have a physical location - provide the address with a link to Google Maps. Clients want to know if you're a real business, not another internet scam. A physical address builds trust faster than anything else.

Service descriptions - specific, not generic

"We offer a wide range of services tailored to your needs." This sentence could be on any company's website in the world. It says nothing. It wastes space. And it signals that either you don't know what you do, or you couldn't be bothered to describe it.

Instead: list specifically what you do. "Full truckload transport (FTL) on Poland-Germany-Italy routes." "Plumbing - pipe replacement, emergency repairs, underfloor heating installation." "Websites for businesses - business cards, landing pages, multilingual sites."

Each service should have 2-3 sentences of description. What it is, who it's for, what the benefit is. No need for an essay. The client scans the page with their eyes, they don't read it cover to cover.

Trust signals

You land on a company's website for the first time. You don't know them. Nobody recommended them to you. Why should you trust them?

This is where these help: client testimonials (ideally with name and company), logos of companies you work with, certifications, years of experience, number of completed projects. Anything that signals: "this company is real and others trust it."

You don't need 50 testimonials. Three will do. But they have to be specific. "Great company, I recommend" doesn't work. "The website was ready in 4 days, they even fixed things I didn't ask for. Highly recommended" - that works, because there's a detail.

Don't have testimonials? Ask your last 3 clients. Most will agree, nobody just thought to ask them before.

"About me" or "About the company" section

People buy from people. Especially in small businesses where the owner is simultaneously the boss, the salesperson, and the person doing the work. Show your face. Write a few sentences about yourself - how many years in the industry, where you're from, why you do this.

It doesn't have to be an autobiography. 3-4 sentences and a photo. A real photo, not a stock photo of a smiling man at a desk. Clients can spot a fake from a mile away.

From my observations - websites with the owner's photo get noticeably more contact inquiries than those without. People want to know who they'll be talking to.

Contact form (simple)

Name, email, message. That's it. Not 15 fields with postal code, tax ID, and a "how did you hear about us?" field. The more fields, the fewer people fill out the form. This isn't an opinion - it's confirmed UX research.

Next to the form: phone number and email. Because some people prefer to call, some prefer to write an email, and some prefer to fill out a form. Give them a choice.

The form must actually work. Sounds obvious, but I've seen websites where the form sent messages into the void - nobody received them because the email was misconfigured. Test after deployment. Send yourself a test message. Check if it arrives.

Technical minimum

Responsiveness. The site must look good on a phone. Over 60% of visits are mobile. If the text is too small, buttons too close together, and the site requires horizontal scrolling - the client leaves.

Loading speed. Under 2 seconds. Ideally under one second. Google demotes sites that load slowly. And users... simply don't wait. 53% of visitors will leave a site if it takes more than 3 seconds to load.

SSL. The padlock in the address bar. HTTPS instead of HTTP. Without it, the browser shows a "this site is not secure" warning. Nobody will leave their details on a site that looks unsafe.

Meta tags. Page title and description that show up in Google. This is the first thing a client sees before clicking your link. "Company XYZ - home page" is a wasted opportunity. "Container transport Gdansk - FTL, LTL, groupage | Company XYZ" - that tells Google and the user what to expect.

Most common mistakes

No phone number at the top. A client comes in from their phone, wants to call. Has to scroll for 3 minutes to find the number. They won't. They'll leave and call a competitor.

Generic service descriptions. "Professional approach to every client." Says nothing. Nobody writes "unprofessional approach." Use specifics instead.

Broken contact form. I've seen this several times. The client writes a message, clicks "send," gets a "sent" confirmation - but the message never arrives. The company is losing clients and doesn't even know it.

No call to action. The website describes the company, services, history. But nowhere does it tell the client what to do now. "Call us," "Write to us," "Check pricing" - this needs to be on the website, clearly and prominently, in multiple places.

A business card website is not a catalog or a portfolio. It's a sales tool. Every element on it should move the client closer to making contact. If something doesn't do that - it shouldn't be there.
