15 Website Design Mistakes Small Businesses Make, and the Fix for Each

The most common website design mistakes on small business sites

A design mistake, on a small business site, is anything that makes a ready customer pause: text they cannot read on a phone, a photo that is plainly not the business, a button that says Submit. The visitor does not complain; they open the next tab.

This guide is for the owner who built the site on Wix, Squarespace, GoDaddy or WordPress and has not looked at it as a stranger since. It starts with a five-minute test, then takes each mistake in the order a visitor meets it, with the fix and its time.

How to tell if your website design is bad: a five-minute phone test

The person who built the site already knows what every page means, which makes them the worst judge of it. The test below takes five minutes on a phone, not a computer, and every pause counts as a fault. Do it now, then once a quarter.

1. Open the homepage on a phone over mobile data, not the office wifi, and count the seconds until something readable appears. Past three seconds, the photos need resizing (mistake 3).
2. Without scrolling, say out loud what the business does, where, and what to do next. If any of the three is a guess, the first screen is the problem (mistake 2).
3. Try to call the business from the page in one tap. If the number is only in the footer, only on a contact page, or is an image, the contact details are hidden (mistake 9).
4. Pick the service customers most often buy and find its page. A bullet in a list is not a page (mistake 10). Then check whether that page says where the business works (mistake 11) and what it costs, or how estimates work (mistake 13).
5. Read the body text without zooming or tilting the phone toward a window. If it takes effort, the contrast or the size is wrong (mistake 4).
6. Tap the main button. If it says Submit, Learn more or Get started, it is not saying what happens (mistake 8). If a pop-up covered the page before the button could be reached, that is mistake 14.

The mistake that is not on the page: a site Google does not show

Before fixing the design, check that anyone sees it. In Theo's audit of 5,974 small business websites (The State of Small Business Websites 2026), 48 percent of the 4,027 sites with search data got an estimated zero visitors a month from Google search, and the median site got an estimated 1. The sample is the sites whose owners ran the free audit, not a random sample. A site with no visitors has a search problem, not a design problem.

If the site gets an estimated zero visitors a month from Google search, the guide to a website not showing up on Google comes first; the fifteen mistakes below are about the visitors the site does get.

What changes when the search problem is worked on

Buy My Lunch, a school lunch ordering service, has been on Theo since June 2026. According to its own Search Console data, Google sent it 929 clicks in the 90 days to September 27, 2026, up from 131 in the 90 days before; search impressions rose from 7,500 to 61,700 over the same two periods, and its average position moved from 13 to 8 as the growth work published pages. Results differ by site, and the design fixes below matter more once visitors arrive.

1. The site was never checked on a phone

A page built at a desk falls to pieces on a phone: the headline wraps into five lines, the phone number is an image that cannot be tapped, the menu needs two hands. The owner rarely sees it, working on a computer.

• A tap-to-call number in the header and footer, thumb-sized buttons, tables that stack, and the main button in the first screen.
• Time: an hour to check, an afternoon to fix in the builder's phone preview.

2. The first screen does not say what the business does

A slogan, a slideshow and a Welcome heading tell a visitor nothing they can act on. "Licensed electrician serving Tulsa, call now" passes; "Solutions for modern living" does not.

• The service and the place in the headline, and under it the promise a customer cares about: licensed and insured, open Sundays.
• One button that names the action and a photo of the real work, not a slideshow; the plumbing demo site below is the pattern.
• Time: an hour, and the highest return of the fifteen.

3. Stock photos, and photos that were never resized

A stock photo of a smiling stranger in a hard hat says this is not the real crew, and the rest of the page stops being believed. The opposite mistake is as common: a photo straight from the phone, 4,000 pixels wide, slow enough to lose the visitor.

• Photos of the real team, shop, trucks and finished jobs; a daylight phone photo beats a stock image.
• Resize every photo to the width it displays at, the top image on each page first.
• Time: ten minutes for the homepage image, an afternoon for fifty photos.

4. Text that is hard to read

Light gray text on white, small sizes and long lines make a page tiring, and a tired visitor stops before the part that would have convinced them. Text over a photo is the usual offender; it vanishes against a bright sky on a phone.

• Body text in dark gray or black on a light background, large enough to read on a phone without zooming, in short lines.
• Text over a photo only with a darkened panel behind it.
• Time: an hour; it is one setting in the builder's style panel.

5. Too many fonts and too many colors

A script font for headings, a serif for the body, a third for buttons and five accent colors read as a flyer, not a business. Each extra font and color is one more thing the eye sorts before it finds the phone number.

• Two fonts at most, one for headings and one for everything else; a third stays in the logo.
• One brand color, worn only by buttons and links; one dark color for text; one light background.
• Time: an hour.

6. Crowded pages and blocks that do not line up

Sections pressed against each other, photos a few pixels off from the text and three content widths on one page look amateur, and a visitor reads that as a judgment about the business.

• Clear space above and below each section and around every button; cut the section that does not help a visitor decide.
• Line text, photos and buttons up to the builder's alignment guides, and keep one content width.
• Time: an afternoon for the homepage.

7. Everything the same size, so nothing stands out

When the headline, the body text and the button all carry the same weight, the visitor has no route through the page. Squint until the words blur: whatever still stands out is what the visitor sees first.

• One large heading per screen, subheadings smaller, body text smaller again, and the button the one element in the brand color.
• Services as a list, not a paragraph, with the answer to the visitor's question first.
• Time: an hour per page layout.

8. Buttons that do not say what happens next

Get started, Submit, Learn more and Click here share one fault: none says what the visitor gets. The label should be the thing that happens: Request an estimate, Book a table, See prices, Call now.

• Name the outcome, and choose one action per page; three buttons on one screen is none.
• The same button at the end of every service page, and a line under the form saying who replies and how soon.
• Time: an hour to relabel every button on the site.

9. Contact details hidden, or missing altogether

A phone number only in the footer, hours nowhere, an address only on a map: each makes the visitor work when they were ready to act. The neighborhood restaurant demo site below puts hours and address on every page and links reservations and ordering to the tools the kitchen uses.

• Phone number, address and hours in the header or footer of every page as tappable text, matching the Google Business Profile.
• A contact page that lists every way to reach the business and what each is for.
• Time: an hour.

10. One Services page for everything the business does

A single Services page listing everything the business does makes the customer do the sorting. A leaking water heater and a bathroom remodel are different questions with different proof, and each search needs its own page for Google to show. The auto repair demo site below gives each repair type its own page.

• Each service customers search for on its own gets its own page: what it covers, who it fits, what it costs or how estimates work, a button.
• The services page examples show the structure.
• Time: an afternoon per page, one a week until the top five are covered.

11. Nowhere on the site says where the business works

A visitor who cannot tell whether the company serves their town assumes it does not, and many sites name a city once, in the footer. The cleaning service demo site below lists its service areas beside its bonded and insured details.

• The main city in the headline and the full service area on its own page, listed by town, with any travel charges or minimums.
• For a shop, the address and parking in the footer.
• Time: an hour for the list, an afternoon if each town gets a short page.

12. Proof that sits far from the claim it supports

Every site says quality, trusted, professional. A visitor looks for evidence instead, and it is usually in the wrong place: logos at the foot of the homepage, a testimonials page nobody visits, a license number on the About page. Proof works beside the doubt it answers.

• A review next to the promise it confirms, the license number next to the word licensed, a job photo on that service's page.
• The guide to building trust on a website lists what to show for each type of business.
• Time: an afternoon to move what exists.

13. No prices, no ranges, and no word on how estimates work

A site with no price anywhere reads as expensive, not flexible. The visitor does not need the exact figure, only to know whether they are in the right place. The barbershop demo site below lists services with prices.

• A starting price, a range, a minimum fee or a package price wherever one can stay accurate.
• When nothing can be quoted, a paragraph on how estimates work: free or paid, on site or from photos, how fast.
• Time: an hour, plus a quarterly check of the numbers.

14. Pop-ups, slideshows and autoplay in the way

A newsletter pop-up on the first visit, a chat bubble over the phone number, a video that starts with sound, a slideshow that moves the button: each one stands between the visitor and the thing they came to do.

• No pop-up on the first screen and never a full-screen one on a phone; put the offer where the visitor is deciding.
• One still photo instead of a slideshow, and video that plays only when tapped.
• Time: ten minutes to switch off; the hard part is deciding to.

15. Details that have gone out of date

One stale detail loses the customer: last year's hours, a price that changed, a team member who left, a booking link that opens an empty page. One wrong detail makes all of them suspect.

• When a service, price, team member or opening hour changes, change it the same day on every page that shows it, and on the Google Business Profile.
• Once a quarter, open every page and tap every link and button on a phone.
• Time: an hour a quarter, and ten minutes on the day something changes.

Which website design mistakes to fix first

Fix the fifteen in the order a customer meets them, one round at a time, and read the numbers a month after each round: calls, form submissions, bookings.

If the site gets an estimated zero visitors from Google search and also fails most of the phone test, a rebuild is usually faster than fifteen patches; the last FAQ gives the rule.
