Seven findings from published research, each with the number, what it means for a business like yours, and a link so you can check it yourself. You shouldn’t have to take a web studio’s word for what a website is worth.

About twenty times faster than a blink
People decide how your business looks before they have read a single word of it.
What that costs you
If your site looks dated, people decide that before your headline has even finished loading. You never get the chance to tell them about the twenty years of experience behind it.
How it was measured
Researchers showed people web pages for half a second, then showed them the same pages for fifty milliseconds. The ratings barely moved, which means nobody was reading. They were reacting to the look.
The most common reason people gave, ahead of everything else
of 2,684 people’s reasons for trusting or distrusting a site
When people explained why they did or did not trust a website, how it looked came up more often than anything else, including what it actually said.
What that costs you
People judge the design before they ever get to your reviews, your licenses or your years in business. An outdated site doesn’t say “established.” It says “possibly gone.”
How it was measured
Stanford asked 2,684 people to judge real websites and say why, in their own words. Nobody was prompted to mention design. It came up in 46.1% of the answers anyway, ahead of the information itself and every other category.
of mobile visits to pages slower than three seconds
More than half of mobile visitors give up if a page takes longer than three seconds to load.
What that costs you
Old sites are usually slow: years of added plugins and photos nobody resized. You’re not losing to a competitor’s better offer. You’re losing before yours has even shown up on the screen.
How it was measured
Google’s own measurements across mobile sites, published in its developer guidance, not in a sales pitch. Their words: “53% of visits are likely to be abandoned if pages take longer than 3 seconds to load.”
Making a site a tenth of a second faster raised sales by 8.4% and the average order by 9.2%.
What that costs you
Same visitors, same prices, but more of them buy. And most older sites are a lot more than a tenth of a second away from being fast.
How it was measured
Deloitte, commissioned by Google, measured 30 million real visits across 37 brands over four weeks: actual shops and actual money, not a survey of opinions. Travel sites saw sales rise 10.1% on the same change.
Vodafone ran the same page two ways at once. The faster version sold 8% more.
What that costs you
This is the clearest number on the page, because only one thing changed. It wasn’t a redesign, a new campaign or a good month. It was speed, measured against an unchanged version running at the same time.
How it was measured
A split test on live traffic: same offer, same audience, same page, one difference. The faster version also turned 15% more visitors into inquiries. Google published it as a case study with the engineering changes listed.
Companies that treat design as a real part of the business grew revenue 32 percentage points faster than their competitors.
What that costs you
The gap isn’t between businesses that have a website and ones that don’t. It’s between the ones that treat how they look as a business decision and the ones that treat it as a chore done once every six years.
How it was measured
McKinsey tracked 300 public companies for five years across three industries (more than two million pieces of financial data) and scored each on how seriously it actually took design. Returns to shareholders grew 56 points faster in the same group.
Seven out of ten online carts are abandoned, and much of that is fixable checkout design rather than people simply browsing.
What that costs you
If you take orders online, the checkout isn’t a technical detail. It’s the last three screens of every sale you almost made, and it’s where a cheap template stops being cheap.
How it was measured
Baymard averaged 50 independent studies for the abandonment rate, and used a decade of its own checkout testing for the fixable share. The leading reasons people give: surprise costs at the end (39%), being forced to create an account (19%), and a checkout that is simply too long (18%).
Put together, the picture is hard to argue with. People judge your business by how your site looks. They do it before they read a word, and they leave if it’s slow. None of that is about taste, and none of it waits until you have time. An outdated site quietly costs you work every month it stays up.
Does this sound familiar?
You already know if this is you.
Five questions. If more than one rings true, your site is costing you something.
This is the most common one. The business has grown, but the site still describes a smaller version of it.
You have real proof, but it’s three scrolls down, in a layout that treats it the same as your office address.
New services, new customers, a new reason to choose you. None of it shows up in the first thing people see.
Four competing buttons are as good as no button. There should be one clear path.
Accurate and forgettable. Everything is technically there, and none of it persuades.
This isn’t a score, a grade or a scan. It’s five questions and your own judgment.
