Three years ago, SEO meant ranking in the blue links. Today, ChatGPT has 200 million weekly users, Perplexity serves 100 million queries a month, and Google's AI Overviews sit above the fold for a significant percentage of searches.
The question isn't whether AI search changes SEO. It does. The question is how, and what to actually do about it.
What's actually different
The zero-click problem got worse
Google's AI Overviews answer the question directly on the results page. If someone asks "what is a voice AI agent", they may never click through to any article. Traffic to informational content is down for many publishers.
What's up: transactional queries. When someone wants to do something — buy, book, hire — they still click. The intent that matters commercially is less affected.
Citations are the new backlinks
When ChatGPT or Perplexity answers a question, they cite their sources. Getting cited is the new backlink — it drives awareness, it signals authority, and it influences how the models describe you.
Getting cited requires: clear, authoritative content on specific topics; proper structured data; clean site architecture that crawlers can parse; and enough domain authority for the AI to trust you.
Long-form authoritative content is winning, not dying
Thin SEO content — 600-word articles stuffed with keywords — is being commoditised. AI can write that faster and cheaper than any agency.
What's harder to commoditise: direct experience, original data, specific case studies, strong point-of-view writing. A post that says "we've run 47 voice AI deployments and here's what we've learned" is harder to replicate than "what is AI automation".
What we actually do differently now
1. Build topical authority, not page-level ranking
Instead of one page per keyword, we build clusters: a core "pillar" page plus supporting articles, FAQs, and case studies that all link to each other. Google and AI models both reward being the source on a topic, not just having one good page.
2. Optimise for structured data
Schema markup, FAQ schema, HowTo schema, and proper semantic HTML mean AI crawlers can extract your content cleanly. It's not exciting work. It significantly affects how you appear in AI responses.
3. Write for citations, not just clicks
The goal of a piece like this isn't just to rank — it's to be the thing someone links when they explain something. That means taking a clear position, citing data, and being genuinely useful rather than vague.
4. Track AI citation mentions alongside traditional rankings
We now include AI citation tracking in every SEO engagement. Are you showing up when someone asks ChatGPT or Perplexity about your service category? If not, there's usually a fixable reason.
What hasn't changed
- Backlinks still matter, a lot
- Technical SEO (speed, crawlability, structured data) still matters
- Content quality still matters
- Domain trust and age still matter
The fundamentals are the same. The surface area has expanded.
The honest take
AI search is genuinely changing the distribution of search traffic. Some businesses are losing traffic they relied on. Others are gaining because their competitors are slow to adapt.
The agencies that will serve clients well in 2026 are those who treat AI citation optimisation as a first-class concern, not an afterthought.
We've been doing that since the start.
