Traditional metrics like click-through rates don't apply to AEO. Brands should instead measure its ROI by tracking increases in branded search, direct site traffic, and direct referral traffic. These metrics indicate that AI-driven recommendations are successfully influencing consumer demand, even without a direct click.

Since clicks from LLMs are low, proving AEO ROI is tricky. Track three key metrics: your brand's share of voice for key prompts, direct customer feedback via "How did you hear about us?" forms, and any referral traffic from the LLM platforms themselves.

Historically, high branded traffic suggested weak marketing. In the AI era, it's a positive signal. Buyers now self-educate on AI platforms, which recommend authoritative brands. They then visit your site directly, making branded traffic a measure of your influence and visibility within these new AI ecosystems.

Don't abandon attribution; evolve it. The old model of single-touch software attribution is outdated. A modern approach triangulates data from software (GA4), self-reported forms ("How did you hear about us?"), and conversational intelligence tools, using AI to identify common buying journey patterns.

Tracking success in LLMs isn't about UTMs, as it's top-of-funnel discovery. Instead, use three key metrics: Share of Voice (% of time you appear vs. competitors), Mention Rate (% of time your brand is mentioned), and Citation Rate (% of time your site is linked in an answer).

For the first time, tools tracking "AI Visibility"—how often a brand is cited in LLM responses—can directly measure the impact of brand-building activities. This allows CMOs to finally prove the ROI of brand investments, treating brand as a quantifiable performance engine rather than an abstract concept.

To properly measure brand presence in AI, use specialized tracking tools (like Profound or Ahrefs) that systematically run hundreds of prompts across various LLMs. These systems track website citations and ranking changes, providing a more reliable, directional view of performance than individual, personalized searches can offer.

Marketers must now measure their brand's presence in AI-powered search results (e.g., ChatGPT, Google AI Overviews). This "AI visibility" metric is crucial for demonstrating relevance and can be tracked without expensive tools, making it an essential addition to any marketing dashboard.

In AI interfaces, a brand's content can influence millions of purchase decisions without a single user clicking a link or seeing the source material. Key metrics must shift from traffic to influence, recommendation rates, sentiment, and share of voice within AI-generated answers.
