# Bots we are tracking

We continuously monitor a wide range of AI bots and crawlers that interact with websites and online content. This includes search engine bots, AI assistants (ChatGPT, Gemini, Grok and Perplexity), and third-party scrapers used by LLM platforms to train or surface content.

By identifying and analyzing these bots’ behavior, we’re able to understand which content is being accessed, how it is being interpreted, and how often it’s being referenced in AI-generated responses. This visibility helps our clients optimize their content to improve discoverability and relevance across AI-driven search platforms.
