Can anyone share real experience or case studies about improving brand visibility through GEO (Generative Engine Optimization)?

I’m trying to understand:

  • How GEO is actually helping brands appear in AI-generated answers

  • What strategies are working

  • Any measurable impact on traffic, mentions, or conversions

  • Whether it’s giving better visibility than traditional SEO in some niches

Would love to hear practical insights, experiments, or results from agencies and in-house teams.
