A client in Cape Town asked us a fair question last month. “I keep hearing I need an AI visibility audit. What am I actually paying for?”
Fair, because the phrase is new enough that anyone can sell anything under it. Some “AI audits” we have reviewed were a standard SEO crawl with the word AI added to the cover page. Others were genuinely useful. This post sets out what a real AI search visibility audit checks, what the report should hand you, and what South African businesses should expect to pay. If you know what to demand, you cannot be sold a repackaged crawl.
What Is an AI Search Visibility Audit?
An AI search visibility audit measures whether ChatGPT, Google AI Overviews, Perplexity and Copilot can find, understand and cite your business, and how often they actually do. It is a different exercise from a traditional SEO audit, which measures how you rank in the classic blue-link results.
The two overlap, but they are not the same test. A site can rank well on Google and still never be named by ChatGPT, because AI answers are assembled from retrieved passages and brand mentions rather than from a ranked list of pages. We covered what Generative Engine Optimisation is in an earlier post if the concept is new to you.
The audit answers three questions. Can AI systems access your content? Is your content usable by them once accessed? And when a potential customer asks an AI tool for a business like yours, who gets named, you or a competitor?
The Six Layers a Proper Audit Checks
A complete AI search visibility audit covers six layers: crawler access, content citability, structured data, brand footprint, current share of AI answers, and competitive position.
1. AI crawler access. Can GPTBot, ClaudeBot, PerplexityBot and Google-Extended reach your pages? Many SA sites block these bots in robots.txt or through their firewall without knowing it, often because a security plugin shipped that way. The audit reads your robots.txt, your CDN settings and your server logs. It should also check whether you publish the llms.txt specification, which several AI tools now read.
2. Content citability. AI answers are built from self-contained passages of 50 to 200 words. The audit scores whether your key pages answer questions directly under clear headings, or bury the answer across four paragraphs of preamble. We explained how AI search engines pick their citations in detail in our playbook post.
3. Structured data and entity signals. Organization schema, Person schema for your authors, consistent business details across your site, LinkedIn, Google Business Profile and directories. LLMs reason about entities. Inconsistent entities get skipped.
4. Brand mention footprint. ChatGPT and Perplexity lean heavily on third-party mentions: review platforms, forums, Reddit, industry directories, news coverage. The audit maps where your brand is mentioned, where competitors are mentioned and you are not, and which sources the AI tools actually pull from for your category. Hellopeter matters more here than most SA businesses realise.
5. Share of AI answers. The auditor runs a structured set of buyer questions through ChatGPT, Perplexity, Gemini and Google AI Overviews, the questions your customers actually ask, and records who gets named. This is the number that matters. Everything else in the audit explains it.
6. Competitive position. The same tests run against two or three named competitors, so the report shows the gap rather than an abstract score.
What the Report Should Hand You
A useful audit report gives you a measured baseline, a ranked list of fixes, and the evidence behind both. Not a health score out of 100 with no working shown.
At minimum, expect the prompt set used and the raw AI answers captured, with dates, since AI answers change week to week. A pass/fail table on crawler access with the exact robots.txt or firewall lines at fault. A page-by-page citability assessment of your top 10 to 20 URLs. A brand-mention gap list naming the specific sources to target. And a prioritised fix list split into what you can do in week one, what needs a developer, and what needs months of content and mention building.
Ask one question before you commission anything: “Will I be able to re-run your measurements myself in three months?” If the method is not repeatable, it is not a measurement.
Red Flags That You Are Buying a Repackaged SEO Crawl
The clearest red flag is a report that never quotes an actual AI answer. If nobody typed your buyer questions into ChatGPT and recorded what came back, your AI visibility was never tested.
Watch for these as well. Screaming Frog or Semrush export pages relabelled as “AI readiness”. Percentage scores with no methodology. FAQ schema presented as an AI fix, even though Google pulled FAQ rich results for most sites back in 2023 and Google’s AI features documentation confirms there is no special markup for AI Overviews. Promises of guaranteed placement in ChatGPT answers, which nobody can guarantee. And any audit priced suspiciously low, because the share-of-answers testing alone takes hours of structured manual work.
An honest audit will also tell you when AI visibility is not yet your priority. If your business has ten total brand mentions on the open web, the audit should say that plainly and point the budget at the foundation first. We made a similar argument about outdated tactics in our post on why 2024 SEO strategies are failing.
What an AI Search Visibility Audit Costs in South Africa
In the current SA market, a credible once-off AI search visibility audit runs between R7,500 and R25,000, depending on site size and how many competitors are benchmarked. Ongoing measurement, where the share-of-answers testing is re-run monthly, is usually folded into a broader search retainer.
Three factors drive the price within that range. Site size, because assessing citability across 15 pages is a different job to 150. Competitor depth, since every benchmarked competitor adds a full second round of share-of-answers testing. And platform coverage: an audit that measures ChatGPT, Perplexity, Gemini and Google AI Overviews separately costs more than a ChatGPT-only check, and is worth more, because the platforms disagree with each other constantly.
How often should you repeat it? For most SA businesses, a full audit once and a share-of-answers re-measurement quarterly is enough. Monthly re-testing only pays for itself once you are actively investing in fixes and mention building, at which point it belongs inside the retainer rather than as a standalone purchase. Re-auditing a site nobody has touched since the last audit tells you nothing new.
One more thing worth saying honestly, since many of the searches that reach this page include “Cape Town” or “near me”. This work is location-independent. The audit is performed on your website, your public brand footprint and the AI platforms themselves. A Cape Town business loses nothing by using a Johannesburg auditor, and the reverse holds too. Choose on method and evidence, not on suburb. We work with clients across South Africa from our base in Gauteng, and the deliverable is identical either way.
What This Means For You
- Ask any provider whether their audit includes recorded AI answers to real buyer questions. No recorded answers, no audit.
- Check your own robots.txt today for GPTBot, ClaudeBot and PerplexityBot blocks. It takes five minutes and it is the most common silent failure we find.
- Budget R7,500 to R25,000 for a proper once-off audit, and treat cheaper offers with suspicion.
- Demand a repeatable method so you can verify progress in three months.
- Fix crawler access and citability before spending anything on brand-mention campaigns.
