🛠️ What is Robots.txt User-agent?
The robots.txt User-agent is a directive used in the robots.txt file to specify which search engine bots are allowed or disallowed to crawl specific sections of a website. It helps control how a site is indexed by directing different instructions to various search engine crawlers.
⭐ Why is the Robots.txt User-agent Important in SEO?
Proper configuration of the robots.txt User-agent ensures that sensitive or non-essential parts of a site are not crawled by search engines, optimizing crawl efficiency and preserving bandwidth. It also helps focus search engines on the most important content, enhancing SEO performance.
⚙️ How Does the Robots.txt User-agent Work?
- A web crawler visits a website and checks for a robots.txt file at the root domain.
- The crawler reads the file to find User-agent directives specific to itself.
- Based on the instructions, the crawler either accesses or refrains from accessing certain areas of the website.
- The robots.txt directives help manage which parts of the site are indexed by different search engines.
📌 Examples of Robots.txt User-agent Directives
- User-agent: * Disallow: /private/
- User-agent: Googlebot Allow: /public/
- User-agent: Bingbot Disallow: /test/
- User-agent: * Allow: /images/
