What are User Agents?
User agents are strings that identify the software making requests to your website. They help servers understand what type of client is accessing the content - whether it's a browser, search engine crawler, SEO tool, or AI bot.
Why This Matters
- Control which bots can access your content
- Identify AI crawlers harvesting data
- Monitor SEO tools analyzing your site
- Understand your traffic sources better
How to Use This Data
- Create robots.txt rules: Block or allow specific bots
- Server configuration: Set up rate limiting for aggressive crawlers
- Analytics filtering: Exclude bot traffic from reports
- Security monitoring: Identify suspicious crawler activity
Tip: Use the Robots.txt Generator to easily create rules for these user agents.
