60% of searches now end without a click. Learn how AI engines decide which brands to cite — and how to measure where you stand.
Check Your AI Visibility Score Free →For two decades, being visible online meant one thing: ranking on Google's first page. You optimised your title tags, built backlinks, and tracked your keyword positions. That model still has value — but it no longer tells the full story.
A new class of search has emerged. When someone asks ChatGPT "what's the best project management tool for small teams?" or asks Perplexity "which e-commerce platforms support B2B pricing?", they don't get a list of ten blue links. They get a single synthesised answer — and either your brand is in it, or it isn't.
The core problem: You can rank #1 on Google and still be completely invisible to the hundreds of millions of users who now go directly to AI engines for recommendations, comparisons, and purchase decisions.
Ninjai Index measures your visibility across four interconnected signals. Each one influences whether AI engines cite you — and how confidently.
Most AI engines that answer questions in real time use a system called Retrieval-Augmented Generation (RAG). When you ask a question, the model doesn't rely solely on what it learned during training — it performs live searches, retrieves content from trusted sources, and uses that content to generate its answer.
Understanding RAG changes your strategy completely:
GEO and SEO share a foundation — crawlability, site speed, and structured data matter for both. But the optimisation targets diverge significantly:
Practical implication: Don't abandon SEO — it still drives significant traffic and supports your GEO credibility. But treat GEO as an additional layer, not a replacement. The brands winning in 2025 are optimising for both simultaneously.
Based on what consistently moves the needle for AI citation rates:

Analyse My Website Free →AI Visibility measures how often and how prominently your brand or website is cited or mentioned in answers generated by AI engines such as ChatGPT, Perplexity, Google AI Overviews, and Claude. It is distinct from traditional SEO ranking, because AI engines do not return a list of links — they generate a single synthesised answer, and either include your brand or they don't.
GEO stands for Generative Engine Optimization. It is the practice of structuring your content, external presence, and brand signals so that AI language models are more likely to cite you as a source when answering relevant queries. GEO focuses on citation frequency and share of voice in AI-generated answers, rather than keyword rankings.
AIEO stands for AI Engine Optimization. It encompasses a broader set of practices — including structured data, schema markup, crawlability for LLM bots, and content formatting — that influence how AI systems understand, index, and reference your brand across all AI-powered surfaces.
Over 60% of searches now end without a click, as users get their answers directly from AI-generated summaries. A high Google ranking does not guarantee inclusion in an AI answer. AI engines use Retrieval-Augmented Generation (RAG) to pull content from sources they trust — your external presence across those sources matters more than your on-page optimisation alone.
You can analyse your website for free using Ninjai Index at index.ninjai.co. The tool scores your site across four dimensions — SEO, GEO, AIEO, and RLS — and provides a prioritised action plan to improve your AI citation rate.
RLS stands for Reputation & Link Signals. It measures the strength and consistency of your brand's presence across authoritative external sources — including review platforms, reference sites like Crunchbase and G2, social profiles, and editorial mentions. In GEO, what others say about you often matters more than what you say about yourself, because AI engines retrieve and rank external sources when generating answers.
It depends on the action. Profile completions on Crunchbase, G2, and X can influence AI citation rates within days — these platforms are indexed and retrieved frequently. Content changes on your own site typically take longer, as AI crawlers need to re-index and RAG systems need to update their retrieval pools. A consistent GEO strategy typically shows measurable improvement in AI visibility within 4–8 weeks.
