Bots are the new users.
AI agents are becoming a primary way the web gets accessed. They crawl, scrape, summarize, and act on behalf of humans. This changes everything about how websites think about their traffic.
Today, GPTBot visits more websites than most humans ever will. ClaudeBot indexes content for AI assistants. PerplexityBot powers search answers. Dozens more are coming.
Website owners need to understand who these agents are, what they're doing, and how to respond. AI companies need to know where they're welcome and where they're not.
