GEO KPIs help you measure whether your business appears in AI answers, whether those answers send visitors, and whether those visitors become enquiries or customers. Start with five measures: brand mentions, linked citations, recorded AI visits, enquiries and confirmed revenue. Keep them separate: appearing in an answer does not prove that it generated a sale.
This guide explains a practical reporting method you can adapt to your business. It includes a hypothetical calculation, original research and a weekly checklist. The examples below are teaching examples, not Grid13 customer results.
Which GEO KPIs should you track?
- Brand mention rate: the percentage of successfully recorded answers that name your business. Count each answer once, even if it mentions you several times.
- Linked citation rate: the percentage of recorded answers that link to your website as a source. A mention without a link is a different result. Save the cited address so you can see which pages appear.
- Recorded AI visits: visits your analytics tool attributes to an AI service. Report the source, landing page and dates. Visits with no identifiable source remain unattributed; do not label them AI traffic.
- Enquiries and conversion rate: the number of recorded AI visits that lead to your chosen action, divided by recorded AI visits. Define that action in advance: for example, a completed enquiry form, rather than a button click.
- Confirmed revenue: money received from customers associated with those enquiries under your stated attribution rule. Keep proposals and open opportunities separate from money received.
These definitions describe your measurement method. They do not establish a universal industry score. For citation examples, see our AI citation tracking guide. For comparisons across brands, read our AI share of voice guide.
How to collect a repeatable weekly sample
Choose a small, fixed set of questions that reflect real buying decisions. Include category questions, comparisons and specific needs. Record the exact wording, language, location, AI service, model where shown, date and whether web search was enabled. Use fresh conversations and keep these conditions as consistent as possible.
As a starting method, run 20 questions three times per service. Record each answer separately. Repetition exposes variation; it does not make the sample representative of all customers. Keep different services separate. If an answer fails to load, mark it missing and report the smaller denominator instead of counting a failure as an absent brand.
Keep a worksheet with one row per answer: question, service, date, successful response, brand mentioned, source linked and cited page. Store your visit and enquiry totals in a separate worksheet for the same date range. This avoids pretending that every sampled answer can be matched to a particular visitor.
GEO KPIs worked example: visibility and enquiries
Hypothetical example: you run 20 questions three times in one AI service and record all 60 answers. Your business appears in 18 answers, and nine answers link to your website.
- Brand mention rate: 18 ÷ 60 × 100 = 30%.
- Linked citation rate: 9 ÷ 60 × 100 = 15%.
During the same week, your analytics records 80 visits from identifiable AI sources and four completed enquiries from those visits. Your enquiry rate is 4 ÷ 80 × 100 = 5%. If none has become a paying customer yet, report four enquiries and no confirmed revenue from those enquiries. If sales records are unavailable, report revenue as not recorded.
You cannot conclude that the nine sampled citations caused the 80 visits. The two datasets cover different events. Nor can you use four enquiries to promise next month's results. Repeat the same measurement and compare like-for-like periods before deciding where to invest more time.
What the original research can tell you
The original GEO paper by Aggarwal and colleagues, first submitted in November 2023 and revised in June 2024, reported visibility improvements of up to 40% in its experimental benchmark. Results varied across subject areas. This is research on visibility in generated answers, not a promise of a 40% increase in your traffic, enquiries or sales.
Seer Interactive's April 2026 study examines Google click-through rates alongside AI Overviews. Its findings concern the businesses and searches in its sample. Use such research to frame questions for your own reporting, rather than applying another site's conversion rate to your forecast.
Google's guidance on AI features says existing SEO best practices remain relevant and that no special optimization is required for AI Overviews or AI Mode. Start with useful, accessible pages and clear links. A special score alone does not guarantee inclusion. Sources checked on 12 October 2026.
What to improve after reviewing the numbers
If relevant questions rarely mention you, review whether your pages explain the service, audience and evidence clearly. Add firsthand examples and sources you can substantiate. If an answer cites a page, check that visitors can find a useful next step on that page. If visits rise but enquiries do not, inspect the page and enquiry process before writing more articles.
For each change, record the page, the edit and the date. Compare subsequent periods using the same definitions. Seasonal demand, other campaigns and changes in AI services can also affect results. Treat an improvement after an edit as a signal to investigate, not proof that the edit caused it. Our generative engine optimization guide provides more background.
Frequently asked questions
Which GEO KPI matters most?
Choose the measure that matches your decision. Mentions and citations describe visibility. Enquiries and confirmed revenue describe business outcomes. Report both, with their dates and limits.
Can Google rankings replace AI answer tracking?
No. A Google position measures a different result from a mention or citation in a particular AI answer. Record each separately using a consistent sample.
How often should I review GEO KPIs?
A weekly review is a practical starting point. Keep the questions and conditions stable, retain missing results as missing, and use longer periods when visit or enquiry counts are small.
Does AI traffic always convert better?
No universal conversion rate applies to your business. Measure your own visits and outcomes using the same date range and action definition. Small samples need particular care.
