We gave a Cape Town plumber 60 chances to be recommended by AI. It got 5.

When a pipe bursts, people used to Google “emergency plumber Cape Town” and start scrolling. A lot of them don't any more. They ask an assistant — “there's water coming up in my yard, who can fix this today?” — and they call whoever it names. So we wanted a straight answer to a simple question: when a customer asks AI for a plumber, does a real, working Cape Town business actually come up?

We picked one and tested it properly.

What we tested

Fifteen questions each, across four assistants — ChatGPT, Claude, Perplexity and Google's AI. Sixty questions in total, all real emergencies phrased the way a stressed customer actually types them: water bubbling up in the backyard with a smell, a kitchen sink overflowing onto the floor, a shower that stays flooded twenty minutes after you turn it off, every toilet in the office blocked before a meeting. No trick questions — just the moments when someone needs a plumber immediately and asks AI who to call.

How often did AI name the plumber?

Five times out of sixty.

On the three assistants most people reach for, a real Cape Town plumber — one that answers the phone and does good work — never came up once.

Who did AI name instead?

It had no trouble naming plumbers. Combat Plumbing, Drainmen, The Drain Surgeon and Vital Plumbing came up again and again. So we looked at where the assistants were getting those names. The answer was simple: the competitors' own websites, and the City of Cape Town's site. That's the whole story in one line — the plumbers being recommended had pages a machine could read; the one that stayed invisible didn't.

Why does AI name one plumber and not another?

An AI assistant doesn't know local businesses the way a neighbour does. It reads what's published on the web and repeats what it can understand. If your website says plainly — in a form a machine can pull apart — who you are, what you do and the area you cover, you get picked up and passed along. If that's trapped inside images, buried in vague copy, or sitting behind code a crawler can't follow, you get skipped. Same trade, same city, same quality of work. The difference is legibility, not merit. The AI isn't choosing the best plumber; it's choosing the one it can read.

What this means if you run a business

The uncomfortable part is how quiet it is. When someone asks “who can fix this today,” they get two or three names and call one. If you're not among them, there's no bounce-back and no missed-call notification. You simply never enter the conversation — and you never find out you didn't. Multiply that across every question your customers ask, every day, and it's a lot of work quietly going to whoever was easier for a machine to read.
