Hello Dear,
- The robots exclusion standard, otherwise called the robots exclusion protocol or simply robots.txt, is a standard utilized by sites to communicate with web crawlers and other web robots.
- The standard determines how to inform the web robot about which zones of the site should not be processed or filtered.
- It's Useful Activity for Promotion.
- It's Part of the SEO On-Page Optimization Activity.
- It's Good for Increase traffic.
Thanks.
