AI engines are rewriting how discovery works. Buyers now ask ChatGPT, Perplexity, and other LLMs for recommendations, and the models decide which brands appear, which URLs they cite, and whose content they trust.
Generative Engine Optimization (GEO) is the discipline that makes this visibility measurable and improvable. It focuses on the signals LLMs actually use: prompt-level presence, citation patterns, source authority, structured data, and technical clarity.
To win inside AI-generated answers, you need clarity on which capabilities matter most, and a platform that can scale with how AI search is evolving. This guide breaks down the GEO platforms shaping the ecosystem, each addressing a specific layer: content authority, messaging clarity, or AI-driven visibility.
Key Takeaways
- GEO is now essential because AI answers, not blue links, are where buyers first discover brands.
- Each tool below supports a different layer of GEO maturity, from basic visibility checks to full AI-search intelligence.
- SEO strengthens the signals AI models trust, but only GEO determines whether your brand gets mentioned or cited.
- Teams should choose a tool based on their current visibility stage, not trends or hype.
- ReSO stands out as the only platform offering end-to-end GEO intelligence across prompts, citations, competitors, and technical readiness.
Reso
Reso is a full-stack Generative Engine Optimization platform designed to help companies understand and improve their visibility inside AI-generated answers. As AI search becomes the first touchpoint for buyers, the platform focuses on the signals that actually determine whether a brand appears in ChatGPT, Perplexity, and AI Overview experiences.
Key Features
1. Prompt Intelligence
Reso maps the real questions buyers ask throughout the journey, from early awareness prompts (“top tools for…”) to deep evaluation queries (“is X better than Y?”). This reveals where your brand should appear, which matters most, and how consistently you’re being surfaced across models.
2. AI Visibility Audit
The platform tracks mentions, citations, and recommendations across major LLMs, showing:
- how often your brand appears,
- in which models,
- for which prompt categories,
- and how that compares to competitors.
It’s the closest thing to “SERP monitoring” for AI-generated answers.
3. Source & Gap Analysis
Reso identifies which URLs and domains LLMs rely on to answer queries in your category, and where competitors are being cited instead of you. This helps teams understand the structural reasons behind their visibility gaps: missing topical depth, outdated sources, untrusted pages, thin third-party coverage, etc.
4. Technical Optimization
LLMs rely heavily on structured signals. Reso surfaces:
- Schema gaps
- Metadata inconsistencies
- Crawl issues
- Broken internal signals
- Missing entity associations
These insights highlight the technical barriers preventing models from discovering, trusting, or citing your content.
5. Content Precision
The platform recommends what to update, consolidate, or create next to increase the likelihood of getting mentioned for high-value prompts. Instead of broad keyword lists, you get AI-specific guidance tied to buyer language and model behavior.
Why teams choose it
Reso connects every part of the AI visibility problem: prompts, citations, sources, technical readiness, and competitive gaps—into one workflow. The result is a clear picture of where a brand stands inside AI-generated answers, and what needs to happen next to improve that presence.
