AI SEO: How AI Agents Are Changing Search Engine Optimisation and GEO

AI SEO means two things: using AI to do search engine optimisation work faster, and optimising your site so that AI-powered search, such as Google's AI Overviews, ChatGPT and Gemini, can find, trust and cite it. AI agents add a third layer: software that carries out SEO tasks instead of only recommending them.

The topic attracts a lot of overclaiming. This guide sticks to what Google, OpenAI and published research actually say, then looks at where AI agents genuinely help a South African business and where they need a person watching.

In short

• Google rewards helpful content however it is produced, but generating pages to manipulate rankings is spam, whether a person or an AI writes them.
• Google says there are no special requirements to appear in AI Overviews or AI Mode: indexed, snippet-eligible pages and normal SEO practice.
• Generative engine optimisation (GEO) makes content easier for AI answers to use and cite. One study found gains of up to 40% in controlled tests, varying by domain.
• AI SEO agents close the gap between audit and fix, but anything published still needs human review.
• Measure both channels: Google Search Console for search, and citation tracking for AI assistants.

What is AI SEO?

The term covers three related jobs:

Meaning	What it involves	Example
AI for SEO work	Using AI to speed up audits, keyword research, clustering and first drafts	Grouping a long keyword list by search intent
SEO for AI search (GEO)	Making content easy for AI answers to find, use and cite	Answer-first pages with clear sources
AI SEO agents	Software that plans, executes and checks SEO tasks with approval rules	Finding thin meta descriptions, rewriting them, monitoring the result

Most "AI and search engine optimisation" debates mix these up. The first is a productivity question. The second is a strategy question. The third is about who, or what, does the work.

What does Google say about AI and search engine optimisation?

Google has been clear on four points, and they set the boundaries for any AI SEO work.

1. Quality, not authorship. Google's guidance on AI-generated content is headed "Rewarding high-quality content, however it is produced," and says "appropriate use of AI or automation is not against our guidelines."
2. Manipulation is spam. The same post says "using automation, including AI, to generate content with the primary purpose of manipulating ranking in search results is a violation of our spam policies." Google's spam policies name "scaled content abuse," with "using generative AI tools or other similar tools to generate many pages without adding value for users" as an example.
3. No special trick for AI Overviews. Google's page on AI features and your website says "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary," and "there's also no special schema.org structured data that you need to add." Pages must be indexed and eligible to show with a snippet. Traffic from these features is reported in Search Console's Performance report under the "Web" search type.
4. FAQ markup is not a shortcut. Since August 2023, FAQ rich results "will only be shown for well-known, authoritative government and health websites." FAQ sections still help readers, but the markup will not win most businesses a rich result.

What is generative engine optimisation (GEO)?

Generative engine optimisation is the practice of making your content more likely to be used and cited when AI systems generate answers. A 2023 paper titled GEO: Generative Engine Optimization, by Aggarwal and colleagues and accepted to KDD 2024, found that GEO methods "can boost visibility by up to 40% in generative engine responses," and that their effect "varies across domains." Treat that as evidence that structure and sourcing matter, not a promised uplift.

How SEO and GEO compare:

	SEO	GEO
Goal	Rank in search results and earn clicks	Be named or cited in AI-generated answers
Where it shows	Google and Bing results pages	AI Overviews, AI Mode, ChatGPT, Gemini, Claude
Foundation	Crawlable, indexed, helpful pages	The same, plus content that is easy to quote
Access	Googlebot and Bingbot	Also AI search crawlers, such as OpenAI's OAI-SearchBot
Measurement	Search Console, rank tracking	Repeated sampling of AI answers

Ranking still matters, but it is not the whole story. In CitedAI's study of 96 South African Google searches on 11 October 2026, the page ranking first was cited in 45 of the 86 AI Overviews that listed sources, or 52%. For a fuller comparison, read CitedAI's SEO vs GEO.

On the access row: OpenAI's crawler documentation recommends allowing OAI-SearchBot in robots.txt if you want your site to appear in ChatGPT search, and says GPTBot, its training crawler, is controlled separately.

What can an AI SEO agent actually do?

Traditional SEO tools are good at finding problems, and many now track AI visibility too. Ahrefs, for example, says its Brand Radar covers ChatGPT, Perplexity, Gemini, Copilot and Google's AI Overviews and AI Mode, per its methodology page. The gap is execution: a report with 200 recommendations still needs someone to do the work.

An AI SEO agent works through that list:

1. Crawl and audit. Find broken links, missing titles, thin pages, slow templates and pages that are not indexed.
2. Prioritise. Rank fixes by likely impact and effort, so the important pages get attention first.
3. Fix within limits. Rewrite meta descriptions, add internal links, correct canonical tags and flag redirect chains, within rules you approve.
4. Draft, not publish. Prepare answer-first rewrites with sources for a person to check and approve.
5. Monitor both channels. Watch Search Console and AI citations, then report what changed after each fix.

For example, a Johannesburg law firm's agent finds 40 practice-area pages with duplicate meta descriptions, rewrites them for approval, and a month later reports which pages gained impressions in Search Console.

Where do AI agents fall short in SEO?

Three places.

• Original substance. An agent cannot invent your case studies, pricing logic or expert opinion. Without them, pages risk being what Google's spam policies describe as content that "provides little to no value to users, no matter how it's created."
• Accuracy. In April 2026 South Africa's Draft National AI Policy was withdrawn after fictitious sources were found in its reference list, which the minister attributed to unverified AI-generated citations. Every fact an agent writes needs checking.
• Scale temptation. Generating hundreds of near-identical suburb pages is the scaled content abuse Google describes. Volume is not a strategy.

How should a South African business start with AI SEO?

1. Check indexing. Use Search Console to confirm your important pages are indexed.
2. Fix the technical basics. Titles, internal links, speed and mobile layout still matter.
3. Decide on AI crawlers. Allow OAI-SearchBot if you want to appear in ChatGPT search.
4. Write answer-first pages. Lead with the answer, cite real sources and keep facts current.
5. Track AI citations. See what LLM citation tracking is and how to measure it.
6. Automate the repetitive work. Use an agent for audits and routine fixes, with human approval.
