A bot is automated software that performs tasks on the web, such as crawling pages, indexing content, or monitoring services.
What a Bot Is
A bot is a program that visits websites automatically. Search engines send bots to crawl and index; other bots measure, monitor, or scrape.
Not every bot is welcome, but knowing them apart is the first step to managing them.
The Bots That Visit Your Site
Search engines operate named crawlers like Googlebot, identified by their user agent. They follow the rules you set and their visits are the lifeblood of SEO.
Other bots include measurement tools, social media scrapers, and malicious scrapers that may ignore your rules entirely.
Why Bot Traffic Matters
- Search bots determine what gets crawled and indexed.
- Analytics must filter bots to report real people.
- Bots can strain servers if they crawl aggressively.
- Some bots steal content or probe for weaknesses.
How to Manage Bots
- Use robots.txt to guide the bots you trust.
- Filter known bots in your analytics.
- Block or rate-limit unknown aggressive traffic.
- Check logs for suspicious bot behavior.
The log: Googlebot crawling your best pages daily, a scraper hammering your whole site hourly.
The plan: let Googlebot do its work, rate-limit the scraper.
The result: clean analytics, happy servers, and content that still gets indexed.
Quick Tip
Keep a bot allowlist for analytics: filter the known search crawlers so your reports reflect real human traffic.
