10 mistakes that make a website look unprofessional

From ill-chosen typography to a lack of hierarchy: the warning signs that send visitors packing.

A website can lose its credibility in a matter of seconds. Here are ten recurring mistakes that drive visitors away — and how to avoid them.

1. Haphazard typography

Too many typefaces, inconsistent sizing, insufficient contrast. Typography is one of the signals our eye picks up most readily, even unconsciously. A well-chosen, well-structured pairing of fonts does 80% of the visual work.

2. Generic imagery

Stock photos we've all seen a hundred times before instantly undermine credibility. It's far better to use fewer images, as long as they're authentic: your premises, your teams, your work.

3. A confusing menu

Too many entries, vague labels, nested submenus. A menu should have no more than five to seven items, with simple, straightforward names.

4. No clear purpose per page

Every page needs to serve a purpose. Without a clear intent, visitors are left wondering what to do next — and they leave.

5. A neglected mobile experience

Buttons too small, text cut off, forms that are a nightmare to fill in. On mobile, the slightest friction is enough to lose visitors.

6. No social proof

No testimonials, no client names, no showcased work. Visitors can't picture themselves working with you. Even a single well-presented case study can change everything.

7. An endless contact form

First name, surname, company, job title, phone number, address, postcode… Half your visitors will give up before reaching the end. A good form needs no more than three or four fields.

8. Garish colours

Too many colours, too many gradients, too much stark contrast. A premium website breathes — it doesn't shout.

9. Empty content

'We are leaders in our field', 'we support your projects', 'our passionate team'… These phrases say nothing at all. Replace them with facts, examples and real figures.
