Most businesses do not lose customers online because of one big disaster. They lose them quietly, every day, because of small problems nobody fixed. Here are the ten mistakes we see most often, and what to do about each one.
1. Nobody can tell what you do
A homepage that opens with "Welcome" or a vague slogan forces visitors to guess. Say what you do and where, in the first line: "Wedding and event venue in Dobrich". Research by Nielsen Norman Group shows that the first 10 seconds of a visit decide whether people stay [1].
2. The site is slow
Every extra second of loading loses visitors, especially on phones. Huge images and unnecessary plugins are the usual cause. Compress images and remove what you do not use. Google's Core Web Vitals recommend that the main content appears within 2.5 seconds [2].
3. It breaks on phones
Tiny text, buttons too close together, content running off the screen. Most of your visitors are on a phone. Check your own site on yours, today. Google mainly uses the mobile version of a site for indexing and ranking [3].
4. Contact details are hard to find
If your phone number is only at the bottom of the contact page, you are losing calls. Put it at the top, and keep a call button visible on phones.
5. No prices at all
"Call for a price" sends many people to a competitor who shows one. Give a starting price or typical examples. Read why in how much a website costs in 2026, the same logic applies to your own prices.
6. Old information
Wrong opening hours, last year's offers, a "news" section from 2021. It makes a business look closed or careless. Keep the basics current, or have someone do it for you. Nielsen Norman Group lists comprehensive, correct and current content among the four factors that make a website trustworthy [4].
7. No proof
No reviews, no photos of real work, no examples. Visitors have no reason to trust you over the next result. Add reviews and case studies.
8. Invisible on Google
No page titles, one page for everything, no Google Business Profile. Nobody finds a site Google does not understand. Start with SEO for a business website: where to start.
9. No security certificate
Browsers warn visitors when a site is "not secure". Many leave immediately, and forms on such sites feel unsafe. A certificate is standard today and should never be missing. Since Chrome 68 in July 2018, Google's browser labels every HTTP site as "not secure" [5].
10. Nobody looks after it
The most common mistake of all: building a site and then leaving it. Software gets outdated, things break, and small problems pile up. A website needs someone responsible for it.
Most of these mistakes take minutes or hours to fix, and each one is costing you customers right now.
How many did you count?
And the biggest mistake of all is having no website: see 5 reasons every business needs a website in 2026.
If your site has three or more of these, it is worth looking at properly. Many can be fixed one by one; sometimes it is faster and cheaper to start fresh. See the difference between a cheap and a professional website, or let us take care of all ten for you with our monthly plan.
