Measuring Success: KPIs for SEO and AIEO

Without measurement, optimization is just guessing – and in the AI era that is doubly true. Alongside classic SEO metrics, an entirely new layer has appeared: visibility in generated answers. Whoever measures both knows what works. Whoever measures only traffic misses half the picture.

Classic SEO metrics

• Organic traffic and above all its quality – conversions, not just numbers.
• Rankings for key queries and their development over time.
• Click-through rate (CTR) from search results.
• The number and quality of referring domains.

New metrics for AIEO / GEO

• Brand mention share in AI answers (share of voice) – how often models list you compared to the competition.
• Citation frequency of your content as a source.
• Accuracy with which AI describes your brand – and whether it contains errors.
• Traffic from AI platforms (referrals from ChatGPT, Perplexity and others).

Beware of vanity metrics

Not every number that grows means success. High traffic without conversions or a thousand mentions with no business impact are so-called vanity metrics – they look nice but say nothing. Assign every metric the question “and what do we really get from this?” and measure what relates to the goal.

How to measure in practice

Regularly ask key questions to individual AI assistants and record whether and how they mention you. Combine this with classic web analytics and rank tracking. What matters most is the trend over time, not a one-off snapshot – and a rising share of mentions is the best proof that investing in SEO and AIEO makes sense.
