TL;DR
If you’ve been keeping up with the GEO conversation (generative engine optimisation – the practice of getting your brand cited by AI-powered search tools like ChatGPT and Google’s AI Overviews), you might be wondering what actually makes AI platforms choose one source over another.
The answer, in large part, comes back to something you’ve likely heard before: E-E-A-T.
What is E-E-A-T and why does it matter?
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It’s a framework Google uses to evaluate the quality and credibility of content, and it’s been central to how Google’s quality raters assess web pages for years.
Google added the extra ‘E’ for Experience back in 2022, placing emphasis on first-hand knowledge – not just theoretical expertise, but real-world, lived understanding of a subject.
Here’s a quick breakdown:
- Experience – Has the author or brand actually done the thing they’re writing about?
- Expertise – Do they have the knowledge and skills to speak credibly on this topic?
- Authoritativeness – Is this brand or site recognised as a go-to source within its industry?
- Trustworthiness – Can users (and search engines) trust the information being shared?
For traditional SEO, these signals influence how Google ranks your pages. For GEO, they influence something slightly different – whether AI platforms choose to cite you at all.
How AI engines assess credibility
AI-powered search tools like Perplexity, ChatGPT, and Google AI Overviews don’t rank pages in a list. They read, synthesise, and generate answers, pulling from sources they consider credible and relevant.
This is where E-E-A-T becomes directly relevant to GEO. AI engines are, in many ways, applying the same logic as Google’s quality raters – they’re looking for content that:
- Is written by people with genuine knowledge or experience
- Is backed by data, citations, and verifiable information
- Comes from a brand or site that’s consistently mentioned across trusted sources
- Is clear, well-structured, and easy to extract accurate information from
In short, if your content checks the E-E-A-T boxes, it’s far more likely to be picked up and referenced in AI-generated answers.
Breaking down E-E-A-T in the context of GEO
Experience: show, don’t just tell
AI platforms are good at spotting surface-level content. What they favour – and what Google favours – is content that reflects genuine, hands-on experience.
For businesses, this means going beyond generic advice. Share real results, real case studies, and real-world examples. If you’ve run 400 campaigns and placed 20,000+ backlinks (as we have at Bulldog), that’s the kind of experience worth weaving into your content – not just stating it, but demonstrating it through the specifics.
Expertise: your content needs to earn its place
Expertise in GEO isn’t just about having credentials. It’s about producing content that’s genuinely useful and accurate – content that covers a topic with depth and clarity.
AI platforms are more likely to cite a well-structured blog post that thoroughly answers a question than a thin page stuffed with keywords. If you’re publishing content on your site, it should reflect real knowledge.
That means answering follow-up questions, including nuance, and avoiding the vague, wishy-washy takes that AI can easily dismiss.
Authoritativeness: build it off your own site, too
Authority is largely built off-page. The more your brand is mentioned in trusted publications, the more both Google and AI platforms treat you as a credible source.
Digital PR is one of the most effective ways to build this kind of authority – earning features in industry publications, securing expert commentary placements, and getting your brand name consistently associated with your area of expertise. These mentions tell AI engines that your brand is a recognised voice, not just another website.
High-quality backlinks from authoritative, relevant sites work hand-in-hand with this. They’re a trust signal for Google and, increasingly, for the AI platforms that are pulling from similar data.
Trustworthiness: the foundation everything else is built on
Trust is where GEO and E-E-A-T intersect most clearly. AI platforms don’t want to cite sources that are unreliable, outdated, or misleading – because doing so would damage their own credibility.
To build trustworthiness in the eyes of AI engines:
- Use accurate, up-to-date data and clearly attribute your sources
- Make your author information clear – who wrote this, and why are they qualified to do so?
- Keep your content factually consistent across your site
- Maintain a positive brand reputation, including reviews and third-party mentions
The practical takeaway
The good news is that if you’re already working on your SEO with E-E-A-T in mind, you’re laying the groundwork for GEO at the same time. The fundamentals overlap significantly.
The brands that will win in AI search aren’t those gaming the system – they’re the ones building genuine authority through quality content, credible backlinks, and a consistent brand presence across the web.
That’s not new thinking. It’s just increasingly important.
If you’re not sure where your content currently stands on the E-E-A-T front – or how visible your brand is in AI search results – that’s a good place to start. Audit what you have, identify the gaps, and build from there.
