How to measure GEO results: metrics and KPIs for AI search
Slug: how-to-measure-geo-metrics-kpis-ai-search
Recently, we have witnessed a major boom in AI technologies, with increasingly powerful systems influencing user behavior.
In the past, although other search engines existed, Google was dominant. Now, people conduct searches across multiple platforms such as ChatGPT, Claude, Perplexity, Gemini, and many others.
As a result, GEO (Generative Engine Optimization) emerged, which is the set of strategies designed to increase the chances of your website being cited by AI systems.
Even though this term is already widely discussed among marketing professionals, many still do not know how to measure GEO results or which metrics should be evaluated.
With that in mind, we created this article to explain the main GEO KPIs, why they differ from traditional SEO metrics, and which tools can be used to measure this success. Follow along below.
Why is measuring GEO results so different from traditional SEO?
One of the main metrics used in SEO is the average page position on Google’s SERP (Search Engine Results Page) for a specific keyword.
Trying to use this same metric for AI systems is almost impossible because the same question can generate different responses depending on the prompt and the user, making exact rankings highly volatile.
Another widely used SEO metric is CTR (Click-Through Rate), which practically does not exist when we talk about GEO.
Searches performed through AI platforms rarely generate clicks, a phenomenon known as “zero-click search,” which has become a major challenge for modern digital marketing because without clicks, there are no website visits.
This leads us to one of the main ways to measure GEO performance: citations.
Main GEO metrics and KPIs for your strategy
The concept of GEO is still relatively new in the market, but we have already identified effective ways to evaluate the performance of this strategy through specific metrics, such as:
Share of Model (SoM) / AI Share of Voice (LVS)
This metric is used to measure how often your brand is cited or recommended in AI-generated responses compared to your competitors.
Tracking these mentions is important to understand whether AI systems recognize your brand as an authority within your niche.
Citation Rate and Mentions
Although GEO cannot rely on the exact same metrics as SEO, there are still some equivalent indicators.
Citation Rate measures the frequency and prominence with which your content and links are referenced by generative engines.
Just as SEO aims for the top positions on the SERP, GEO aims to appear within the first two sentences of an AI response, which can generate five times more user consideration compared to being mentioned at the end of the answer.
Sentiment Analysis (Sentiment Score)
One of AI’s greatest strengths, which has driven many users toward these platforms, is its conversational tone.
This means that searches are no longer just simple queries, they now resemble personalized advice.
Because of this, one of the best ways to evaluate GEO performance is by analyzing the tone AI systems use when mentioning your brand.
If these tools consistently associate your company with bugs, problems, or negative reviews, conversion rates will likely suffer.
AI Referral Traffic
It is essential to measure how many website visits originate from recommendations made by AI platforms.
This is because traffic coming from artificial intelligence tools usually has a high conversion intent, as users have already been “guided” by the AI-generated response.
Metric variations depending on the AI model
Recently, we have seen an explosion of AI systems entering the market, and each one has its own characteristics and methods for recommending web pages.
Understanding this concept is essential for accurately measuring your AI SEO performance.
For example, Google recently released documentation addressing certain “myths” about appearing in its AI systems (Gemini and AI Overviews), stating that no specific optimization strategy is required beyond strong SEO practices.
However, this does not mean all AI systems follow the same guidelines, and it is important to understand the behavior of each platform to align expectations and measure results effectively.
For instance, research within the detergent market showed one brand dominating 24% of mentions in Meta’s Llama AI, while appearing in less than 1% of mentions in Google’s Gemini.
This demonstrates the importance of monitoring where your target audience is searching and evaluating metrics for each AI platform individually.
Without the right metrics, GEO becomes trial and error
With the rise of AI, GEO has become a major force within digital marketing, serving as the set of strategies that optimize your website to appear as a trusted source in AI-generated responses.
Like any strategy, GEO performance must be measured, but which metrics should be used when the concept itself is still so new?
