How to Measure AEO and GEO Success: A Practical Scorecard

Answer engine optimisation (AEO) and generative engine optimisation (GEO) aim at the same outcome: getting your brand named and cited inside AI answers. The hard part is proving it works. Rankings tools don't show AI answers, and AI referrals are only a fraction of the influence. Here is a scorecard you can run every month.

Short answer: measure AEO and GEO with four numbers. Share of answer (how often you are mentioned for your target questions), citation rate (how often your pages are linked as sources), AI referral traffic, and AI-influenced pipeline.

Step 1: Build your question set

List 30 to 50 questions your buyers actually ask, such as "best [category] tool for [use case]", "[competitor] alternatives", and "how to [problem you solve]". Pull them from sales calls, support tickets and Search Console queries. This set is your measurement baseline, so keep it stable.

Step 2: Measure share of answer

Run each question in ChatGPT, Perplexity, Gemini and Google AI Overviews. Record whether your brand is mentioned, its position in any list, and which competitors appear.

Share of answer = answers mentioning your brand ÷ total answers checked. Run the same questions monthly, ideally in a fresh session without history.

Step 3: Measure citation rate

Mentions and citations are different. A citation means your page is linked as a source. Track which of your URLs get cited and for which questions. Pages that are cited often tell you which formats work: usually clear definitions, comparison tables and step-by-step guides. Our guide on getting cited by AI tools explains why.

Step 4: Track AI referral traffic

Set up a custom channel group in GA4 for chatgpt.com, perplexity.ai, gemini.google.com, copilot.microsoft.com and similar sources. Full steps are in how to track traffic from AI platforms. Watch landing pages and conversion rate, not only volume: AI visitors often convert better because they arrive pre-qualified.

Step 5: Connect to pipeline

• Add "AI assistant (ChatGPT, Perplexity, etc.)" as an option in your "how did you hear about us?" field.
• Pass the AI referral source into your CRM.
• Report AI-influenced opportunities each quarter.

The monthly AEO scorecard

• Share of answer across your question set, overall and by AI platform.
• Citation rate and top cited URLs.
• Competitor share for the same questions.
• AI referral sessions and conversion rate.
• AI-influenced pipeline, quarterly.

Leading signals to watch

Before share of answer moves, you will usually see: AI crawlers visiting your site in server logs, more impressions for question-style queries in Search Console, and new third-party mentions. If none of these move after two months, look at the basics in why SaaS sites are invisible to AI, including crawler access and an llms.txt file.

How long until results?

AI answers built on live search, like Perplexity and AI Overviews, can change within weeks of a page improving. Answers based on model training change more slowly. Expect early movement in 4 to 8 weeks and meaningful share-of-answer gains over a quarter. Want a baseline for your brand? Get the free SEO and AEO audit.
