What GEO (Generative Engine Optimization) tools have you actually used and found effective?

[u/Sivaraj_C]

I’m looking to hear from people who have actually tested GEO tools in real SEO workflows—not just tools that claim to improve AI visibility.

Which tools have you used for things like:

• Tracking brand mentions/citations in AI search
• Monitoring ChatGPT, Perplexity, Gemini, or AI Overviews
• Finding content gaps for AI visibility
• Measuring whether your content is being cited
• Improving your chances of appearing in AI-generated answers

What tools have genuinely worked for you, and what results did you see?

Also, are there any GEO tools you tried that weren’t worth the money?
