Traditional SEO optimised for one goal: rank as high as possible in a list of blue links. AI search tools like ChatGPT, Perplexity and Google's AI Overviews answer a question directly, often without the user ever clicking through — which shifts the goal from ranking first to being the specific source an AI system chooses to cite.
What's genuinely changing
Zero-click search — where a user gets their answer without visiting any website — is becoming more common, which means visibility inside an AI-generated answer matters even when it doesn't translate to a direct visit. Third-party mentions (being cited or referenced on other authoritative sites) are proving more influential to AI citation than they were to traditional ranking.
What's staying the same
Genuine authority, accurate information and real usefulness to a reader still underpin both traditional rankings and AI citations — this isn't a wholesale replacement of good SEO practice, it's an extension of it. Google has been explicit that no special markup is required purely for AI Overviews; strong, clear, well-structured content already helps both systems.
Practical adjustments worth making
- Write clear, self-contained, extractable answers to genuine questions your audience actually asks.
- Build real third-party presence — press mentions, guest content, directory listings — since AI systems weigh external validation heavily.
- Don't block AI crawlers in robots.txt unless there's a specific, deliberate reason to.
What to avoid
Writing content specifically to game AI citation, disconnected from genuine usefulness to a human reader, risks running into the same low-value-content policies that hurt traditional SEO — the fundamentals haven't actually changed, only one more place they now apply.
