The Phone Test: How Many Tradesmen's Websites Fail on Mobile

The large majority of searches for local trades happen on a phone. So we checked nearly 5,000 trade businesses the way a customer would: on mobile. A lot of them fail the test before a word is read.

A website that does not work on a phone is worse than no website at all, because it actively turns customers away. Our audit found a quarter of tradesmen have no site, and many of the rest fall down on exactly the screen their customers are using.

Here is how trade websites perform on mobile, why structured data is the new invisible barrier, and why more than half are effectively invisible to modern search.

How we did this

Sample: 4,895 UK trade businesses across 61 towns and 25 trades, concentrated in Hertfordshire and the surrounding South East of England. Collected: 2026, from public Google Business Profiles and business websites. All percentages from our own data are of the businesses we analysed, not a national census. Because every business was found via Google in the first place, our figures most likely understate the true gaps. External figures are cited and linked inline.

The key findings

Your customers are on a phone, in a hurry

When a boiler dies or a roof leaks, the homeowner is searching on a phone, often with several tabs open, and they are not patient. A site that loads slowly, needs pinching and zooming, or hides the phone number loses them in seconds to the next result.

This is the most basic test a trade website has to pass, and our data says a meaningful share fail it. A non-responsive site is not a small flaw. On the screen most of your customers use, it is the whole shop window falling over.

Mobile-friendly is the floor, not the ceiling

Fourteen percent of the trade websites we checked are not mobile-friendly at all. That is the obvious failure. But passing the mobile test only gets you to the starting line, because being readable on a phone is now assumed, not impressive.

The sites that win are fast, with a tappable number on every screen and the service area spelled out. Most trade sites we looked at were built on heavy templates that are slow before they are anything else.

Schema is the new invisible barrier

Here is the part most tradesmen have never heard of. Schema markup is structured data that tells Google and AI engines exactly what a page is: the business, the services, the area, the reviews. It is invisible to humans and essential to machines. In our audit, 39% of trade websites have none.

Without it, a perfectly nice-looking site can still be skipped by the rich results and AI answers that more and more homeowners rely on. The page exists, but the machines that increasingly do the recommending cannot read it properly.

More than half the market is invisible

Combine the two problems, no website and a website with no structured data, and 54% of the trade businesses we analysed are effectively invisible to modern search. As AI search and rich results take over more of how people find local trades, that share is the gap between being found and being skipped.

It is also the opportunity. A fast, mobile-first site with proper structured data puts you ahead of more than half your local competition, most of whom do not even know the gap exists.

Quick test: open your website on your own phone right now. Does it load in a couple of seconds, fit the screen, and let you call the business in one tap? If not, that is costing you work every week.

Frequently asked questions

How many tradesmen's websites are not mobile-friendly?
In our 2026 audit of 4,895 UK trade businesses, 14% of those that had a website were not mobile-friendly, and a further 25% had no website at all. Most local trade searches happen on a phone.
What is schema markup and why does it matter?
Schema is structured data that tells Google and AI engines what a page is about: the business, services, area and reviews. It is invisible to humans but essential to machines. 39% of the trade websites we checked had none, which limits how well they can be found and cited.
What does it mean to be invisible to AI search?
We counted a business as invisible if it had no website, or a website with no schema. 54% of our sample fell into that gap. As AI answers and rich results grow, structured data increasingly decides who gets surfaced.
