Editor’s pick
Best forcontent and SEO teams or agencies that want one subscription covering content briefs, AI-assisted drafting and daily AI citation tracking
VerdictFrase has expanded into an AI-visibility optimization platform, and citation tracking now ships from the $39/mo Starter plan (ChatGPT and Google AI) rather than being Professional-gated. Multi-engine coverage still scales with tier: Perplexity on Professional ($103+/mo), Claude and Gemini on Scale ($239+/mo).
- Price
- From $49/month · source
- Free to try
- 7-day free trial
- Watch for
- AI Visibility (GEO) tracking starts on Starter with two engines. Full five-engine coverage (adding Perplexity, Claude, Gemini) requires Scale ($239/mo billed yearly).
Best forMarketing teams and brands that already run SEO/content operations
VerdictAn enterprise-grade GEO platform that treats AI-visibility optimization as a first-class problem: tracks citations, ranks fixes by impact, audits AI-crawler access, and agents content to add FAQ blocks and citation-friendly passages. The deepest technical GEO layer in this index. Starter $79/mo billed annually, Growth $399/mo, full 10-platform visibility at custom-priced Enterprise.
- Price
- From $99/month · source
- Free to try
- 7-day free trial
- Watch for
- Full multi-platform AI-visibility tracking (Perplexity, Claude, Grok, DeepSeek, Copilot, Meta AI, Google AI Mode) is gated behind the custom-priced Enterprise tier.
Best forContent and SEO teams already optimizing articles at volume who want AI-answer visibility tracking bolted onto an existing Surfer subscription
VerdictA mature content-optimization platform that extended into AI-answer visibility: AI Tracker monitors ChatGPT, Perplexity, Google AI Overviews, Google AI Mode and Gemini on a schedule, and optimization recommendations flow into the article editor. Best for teams already writing at volume. Plans Discovery €49/mo (about $55) through Enterprise €999/mo (about $1,118), with AI Tracker standalone €158/mo (about $177).
- Price
- From about $66/month · source
- Free to try
- 7-day free trial
- Watch for
- AI prompt tracking is excluded from the Discovery tier and starts at 25 prompts/week (ChatGPT only) on Standard.
Best forEnterprise marketing teams and agencies that need broad AI-engine coverage plus MCP access
VerdictBroad AI-engine coverage (17+ engines globally) and enterprise customers, with optimization recommendations tied to citation impact. Credit-based pricing gets expensive fast, but the breadth and depth of multi-LLM tracking is unmatched for enterprises. Pro at $99/mo is the first displayed self-serve tier.
- Price
- From about $111/month · source
- Free to try
- 7-day free trial
- Watch for
- No GA4 or analytics integration for connecting AI visibility to traffic or revenue
Best formid-market marketing teams and agencies running AI-visibility programs
VerdictThe strongest mid-market pick for a focused GEO program: citation-source mapping is granular, pricing is straightforward (€70 (about $78)–€360/mo (about $403)), and the product is built GEO-first rather than tacked onto a SEO platform.

Questions buyers ask
What is LLM SEO (GEO/AEO)?
LLM SEO (also called Generative Engine Optimization or GEO) refers to the practice of optimizing your content and technical setup so that AI models like ChatGPT, Perplexity, and Gemini cite your brand in their answers. Unlike traditional SEO, which targets search-engine result-page rankings, LLM SEO targets AI-generated answers. Tools in this category help you identify opportunities, optimize content structure and messaging, and track how your optimizations improve citations.
How is LLM SEO different from measuring AI visibility?
Measuring AI visibility (tools on our main pillar, "The best AI visibility tools") tells you WHETHER and HOW OFTEN AI engines cite you. LLM SEO (this page) is about IMPROVING those citations. The tools here include content optimization, citation-impact prioritization, and technical auditing to help you get cited more. Most organizations measure first (to know where they stand), then optimize (to improve).
What should I optimize to improve LLM citations?
Three main levers: (1) content structure, FAQ blocks, comparison tables, and self-contained paragraphs answer common questions the AI might cite you for; (2) topical coverage, write comprehensively on topics your audience asks AI about; (3) technical, ensure AI crawlers can access your pages, that schema is correct, and that robots.txt doesn't block indexing. Most tools on this page help with levers 1 and 3; measure with our monitoring tools to track the impact.
Do I need to choose between optimization and monitoring?
No. Most teams use a pair: one tool to measure (from our "AI visibility tools" pillar) and one to optimize (from this page). Some tools, like Frase and Writesonic, bundle both. Start by choosing your optimization strength (content operations vs. technical depth vs. broad engine coverage), then add a dedicated monitor if your tool doesn't include one.
Are there free or open-source LLM SEO / GEO tools?
Yes, three tools on this page are free and self-hosted: Canonry (source-available, audits AND executes JSON-LD/WordPress fixes, ships a 67-tool MCP adapter), GEOrank (Apache-2.0, a diagnostic and content-generation workbench with a Claude Agent Skill for agent-driven self-hosting), and auto-geo (MIT-licensed CLI that audits, generates, fixes and measures citations, CI-gateable). All three need your own AI-provider API key and real setup time in exchange for zero subscription cost, and none monitors Google AI Overviews as completely as the paid platforms above.
Is this the same as "AI content optimization tools"?
"AI content optimization," "LLM SEO," and "GEO" (Generative Engine Optimization) all describe the same practice, shaping content and technical setup so AI engines cite you, and vendors and buyers use the three terms inconsistently. Every tool on this page fits under all three names; if you searched for AI content optimization tools, this is the same comparison.
