  1. How AI Crawlers Read Your Site

    AI crawlers such as GPTBot, ClaudeBot and PerplexityBot fetch your raw HTML and execute no JavaScript, so content that only appears after scripts run is invisible to them. Each vendor runs separate bots for training, search and user requests, and blocking the wrong one removes you from answers without protecting anything.

  2. What Is llms.txt, and Do You Need One?

    llms.txt is a proposed plain-text file at your site root listing the pages AI systems should read, in Markdown. The honest evidence: no major engine documents consuming it, and 97 percent of the files in a 137,000-domain log study received zero requests. Ship one only because it is cheap, never as a visibility lever.

  3. AI Share of Voice: How to Calculate It

    AI share of voice, or AI SOV, is the percentage of AI assistant answers that name your brand, measured across a defined panel of prompts, platforms and repeated runs. Divide the answers naming you by the total analysable answers. It is the AI-search equivalent of share of voice in advertising, applied to AI-generated answers.

Every article here is in the RSS feed, is readable as clean Markdown by adding .md to its URL, and ships in llms-full.txt, the single file that carries the whole corpus for an AI assistant to read in one request. And if Google is your front door, you can add RankX AI as a preferred source, which asks your own results to surface more of what we publish.
