Great design, no sales? 6 UX mistakes killing your conversions

The designer is done. Colours work, fonts are clean, every screen looks good enough to screenshot. Client happy, team happy — a month later, enquiries are flat or lower. Ads get clicked, traffic goes up, and the phone still doesn't ring. It's the question we hear most: "the site looks great, so why isn't it selling?"
The answer sits in the same place almost every time: a visitor decides by whether they can find the right page, the price, and a safe-feeling form — not by whether a colour is nice. Six mistakes cause most of it, and all six are cheap to fix.
Navigation and buttons: if people don't know where to go, they leave
These shape the first impression before a visitor reads a word.
1. Navigation that mirrors your org chart, not the visitor's question
Open your menu and count the items. More than nine, each with four sub-items, and a visitor already knows to leave — from the list's length alone. "Legal services ecosystem" makes sense to the lawyer who wrote it; a visitor wants "Services" or "Book a consultation." Every extra item is a guess, a retry if wrong, and a costly tap on mobile — after two or three misses, most people leave.
Fix it this week: check which five questions come up most — usually price, services, contact, past work, "who are you" — keep the menu to those five, move the rest to the footer, and name each item the way a customer says it on the phone.
2. Buttons that don't promise anything
Write down every button's wording. How many say "Learn more" or "Click here"? Same words on every page, none says what the visitor gets. Clicking toward an unclear result feels riskier on mobile, where going back costs one tap, so people just close the tab.
A strong button promises the outcome up front: "Get a price estimate", "Book a free call", "See our work". Read every button alone this week — does it still make sense? If not, swap the verb for a concrete result and add a word of reassurance: "free", "in 24 hours". "Submit" promises nothing; "Send your request, we reply within a day" does.
Price and forms: the barrier that shows up last
A visitor who made it this far is already interested — losing them here is the costliest drop-off, since the ad spend that brought them is already gone.
3. A price that's hidden or only revealed at the end
Baymard Institute's review of 50+ studies found 40% of shopping cart abandonments happen because extra costs — shipping, tax, fees — only surface at the last step. Is there a pricing page on your site, or just "Send an enquiry, we'll call you"? A repair shop with no prices doesn't get a call about an oil change — the visitor opens the next tab, where a competitor already answers it, rather than risk a call ending in "outside your budget."
Fix it this week: an exact figure isn't required, but a starting price ("from…"), a range, or the factors that move it should be on the page — so calls come from people who already accepted the number.
4. A form with more fields than it needs
The same research ties 17% of abandonment to a checkout that's "too long or complicated" — an optimal form runs 12–14 fields, the average site asks 23+. Look at your form: name, phone, email, company, job title, budget, date of birth — ten fields already puts you at the average. Every extra field is one more "is this asking too much?", sharper on a small keyboard, where people abandon halfway — a lost lead either way.
Ask a question of every field: does it need answering now, or can it wait for the call? Name, phone, one line about the need — usually that's the whole form. Move the rest into the conversation that follows, once they're already interested.
Trust and mobile: the part nobody notices consciously
Neither shows up as a number on screen, but together they decide whether the form gets filled in at all.
5. No signal that a real business is behind the site
Only an email in the footer, no phone number? An "About" page of two sentences, no team photo, no real work shown? A visitor doesn't know you, and even a flawless site leaves one question open: "is this real, or will it vanish once I submit this form?" Handing over a phone number and email to an address you can't verify is a small risk, and without reassurance the brain picks the safe option: nothing. This hits new businesses hardest — a recognisable name already carries trust a smaller studio has to earn from the site itself.
Fix it this week: add a real address (a small office counts), a phone number that gets answered, work you have permission to show, and a short "who we are" paragraph. Skip invented numbers like "hundreds of happy clients" — one real example convinces more than an unverifiable statistic.
6. Details that got skipped on mobile
Design tested on a large monitor, but most visitors arrive on a phone — the symptom won't show on desktop: text that needs pinching to read, buttons close enough that you hit the wrong one, a keyboard that covers half the page so "Submit" disappears. Research on interactive target size confirms a simple rule: bigger targets get hit more often — small, crowded buttons cost the order, since two or three mistaken taps and most people close the form.
Fix it this week: go through the site on your phone, thumb only, no zooming, start to finish. Tap every button and link once. Is text readable unzoomed? Does "Submit" stay visible above the keyboard? Almost every problem you find will be a spacing fix, not a rebuild.
What to do: run this list against your own site
None of these six mistakes comes down to a designer's skill — all six live in how the user's path was planned. A good design earns attention; the right path turns it into a result. Checking your site against this list takes about fifteen minutes; fixing most of it is a day's work:
- Open the menu on your phone — can you find what you need in three seconds?
- Read every button alone — does it promise an outcome, or just say "learn more"?
- Look for a line about price — is it there, or total silence?
- Fill in the form yourself — how many fields, and which are actually needed?
- Check the address and phone number — specific, or a vague placeholder?
- Walk through the site with your thumb — do the buttons land where you expect?
Every "yes" is working for you; every "no" will show up in tomorrow's enquiry count.
A beautiful site earns attention — the right user path is what turns that attention into revenue.
If more than three items sound familiar, the problem isn't the design itself, it's the user experience planning behind it. We don't rebuild a site on a guess — we measure the exact step where visitors drop off, then fix only that step.
