Questions & Answers

As answered by people managing LLMrefs and Underscore Done.

Why should a person choose your product over its competitors?

LLMrefs's answer

  1. Track keywords, not prompts Most AI SEO tools make you manage individual prompts. LLMrefs lets you add keywords and automatically generates prompt variations based on real conversations users have with AI chatbots. This saves time and produces more realistic results.

  2. Statistical significance, not magic numbers Many competitors show vague "visibility scores" that are hard to interpret. LLMrefs uses transparent metrics like Share of Voice and Position. Results are aggregated and weighted across every prompt variation to ensure statistical significance.

  3. Affordable with no hidden fees LLMrefs Pro is $79 per month and includes all 11 AI search engines. Competitors often charge extra per engine or have tiered pricing that gets expensive quickly.

  4. Agency-friendly from day one One subscription covers unlimited projects and unlimited team members. Agencies do not need to buy separate accounts for each client.

  5. Data quality focus LLMrefs emphasizes being the only platform that takes data quality seriously. They continuously check prompts and only report results when they have enough data to be statistically significant.

  6. Comprehensive engine coverage Eleven AI search engines tracked in one dashboard. You do not need separate tools for ChatGPT, Perplexity, Google AI Overviews, and others.
