Every industry has a different AI shortlist. We measured three.

Ask an AI assistant who the best estate agents in Cape Town are, or the best law firm for a contract dispute, or who should handle your company's audit, and you get back the same thing: a shortlist. Three or four names, stated as fact. The buyer reads those, and only those. There is no page two of a sentence.

So we spent a month reading the shortlists back. We put the questions real South African buyers ask to the four assistants they actually use — ChatGPT, Claude, Gemini and Perplexity — across three industries: residential property, law, and accounting. Every prompt was sampled several times per engine; every answer's sources were traced. 1,296 grounded answers in all. Today it becomes a permanent, public instrument: the SA AI Visibility Index.

We expected the household names to dominate, the way they dominate billboards and boardrooms. What we found instead is that each industry has its own shape — and one blind spot they all share.

AIV Index research — the SA AI Visibility Index, Edition 1 — 1,296 grounded answers across South African property, law and accounting, measured across June and July 2026 and analysed at the source-URL level.

Three industries, three completely different shapes

Property is a monarchy. Pam Golding Properties is named in 45% of all answers — a wide margin over a clear second — and when it is named, it is presented as a recommended choice 91% of the time, a conviction no rival reaches. One brand owns the category's AI mindshare almost outright.

Legal is a fractured parliament. No firm dominates: Bowmans leads at just 15%, with Adams & Adams, Cliffe Dekker Hofmeyr, Webber Wentzel, ENS and Werksmans all clustered within three points behind it. Volume is close, so conviction does the separating — Webber Wentzel is recommended in 96% of the answers that name it, the highest conviction we measured anywhere this edition.

Accounting is an upset. The Big 4 don't top the list. BDO is named in 28% of answers, ahead of Forvis Mazars (20%) and PKF (16%); Deloitte and PwC sit mid-table at 14%, and EY places ninth of the twelve firms tracked. The buyer questions aren't "who audits the JSE" — they're small-business accounting, tax practitioners, payroll — and on those, the engines reach straight past the biggest brands in the profession. Xero, a software platform, is named more often than KPMG.

Your industry's AI shortlist has a shape. You can't manage what you haven't measured.

AIV Index research — Edition 1, per-industry league tables (property, legal and accounting; 432 grounded answers each).

The most consistent finding isn't about content. It's about doors.

Cross the three industries and one pattern repeats: big names were refusing AI crawlers at the server when we measured them, while a normal browser got the page. RE/MAX in property refused GPTBot. Adams & Adams in legal refused ClaudeBot. PwC in accounting refused all three crawlers we tested: GPTBot, ClaudeBot and PerplexityBot. Every refusal was a 403, reproduced on a second fetch.

Most of those refusals hit training crawlers. By their operators' own descriptions, GPTBot and ClaudeBot collect training data, while ChatGPT and Claude find pages for their answers with different crawlers, OAI-SearchBot and Claude-SearchBot, which Edition 1 didn't test. So a GPTBot block tells you nothing about ChatGPT search. PwC's is the one that reaches the answers: PerplexityBot is the crawler Perplexity uses to find pages.

None of it was in the robots.txt file the standard SEO audit checks. The refusals came one layer down, at the web server or firewall, almost always from a stock security setting nobody chose.

So how does an engine name a firm whose site it can't read? Other people's pages. In legal, the most-cited sources aren't law firms at all — they're directories: attorneys.co.za (155 citations), Lawzana (125), Best Lawyers (97) and Legal500 (69). The mediator layer is writing the profession's AI story. It is resilience by accident, not design — and it holds only while someone else keeps describing you.

What the engines can't read, someone else describes for you.

The block itself is usually a one-line fix, but you only fix it if you know to look — and the only way to catch it is to fetch your own site the way each engine's search crawler does, one crawler at a time. You can run that check on your domain in about 30 seconds, free: check whether AI can read your site.

AIV Index research — Edition 1. Crawler refusals measured by direct per-bot fetch from our servers at measurement time, reproduced on a second fetch, with a normal browser served the same page. Legal citation counts from the source-URL analysis.

The ground is still open

The last pattern is the most encouraging one. In every industry, brands nobody is tracking are already in the answers. Burger Huyser Attorneys — a consumer-focused firm that wasn't on our tracked list — was named 46 times in legal, effectively level with the Big Five corporate firms. Fine & Country surfaced 40 times in property without being tracked. In accounting, Sage, Tax Consulting South Africa, QuickBooks and Nexia SAB&T all register unprompted.

None of them got there on size or ad spend. The engines reward corroborated, question-shaped presence — being written about where a machine can reach it, on the questions buyers actually ask. That is why conviction, not fame, is the currency: Webber Wentzel at 96%, Pam Golding at 91%, and in accounting the tax-filing platform TaxTim recommended 91% of the times it is named. Standing in the room counts for nothing the machines can read.

Which is the opportunity. This is the rare discovery channel where early still beats big — the incumbents largely haven't noticed it started, and the engines publish no rankings of their own. The only scoreboard is the one you build.

Where your brand stands

The shape of your industry is one thing; your place in it is another, and it is specific to you. The order of operations is short and the same everywhere:

1. Check your doors. Fetch your own site as each engine's search crawler — the actual server response, not the robots.txt. It is the cheapest move on this list. Run the free check.
2. Get corroborated. Earn a presence on the directories, review sites and guides the assistants read in your category. In a crowded market that is the floor; in a thin one, a well-built brand site can become the source the engines lean on.
3. Measure all four engines. Your ChatGPT result is a quarter of the story — the four assistants behave like four different search engines, and the same brand can win one and vanish from another.

The Index recurs quarterly, same prompts and same method, so the next edition's story is drift: who gained, who fell, who fixed their front door. The full league tables, every prompt panel and the downloadable data for all three industries live on the SA AI Visibility Index. Where your own brand sits — which engines already leave you off, which sources matter in your category — you can measure directly.

Two companion pieces go deeper on the property story, and on the lever everyone reaches for and shouldn't: why South Africa's most famous estate agencies are invisible in AI and schema markup won't get you cited by AI — here's what does.
