Every major AI assistant uses web crawlers to index website content. Here is how it works:
Step 1: The crawler checks robots.txt Before accessing any page, the crawler reads your robots.txt file to see if it has permission. Most website platforms block AI crawlers by default—meaning GPTBot, ClaudeBot, PerplexityBot, and others are denied access.
Step 2: If allowed, the crawler reads your content The crawler visits pages, reads content, headings, meta tags, and structured data. It builds a representation of your business in its knowledge base.
Step 3: The AI uses this knowledge When a user asks a question relevant to your business, the AI draws from its crawled knowledge to formulate an answer. If your website was never crawled, you are not in the AI’s knowledge base.
