A robots txt builder can make the task of creating web crawl instructions easy. Rather than manually writing all the rules, the user simply needs to input the URL's that he/she wants to allow or disallow the crawlers to access. Generally, the robots.txt file contains directives like User-agent, Allow, Disallow, and Sitemap. ToolFlora's robots.txt generator can prove useful for writing these directives and creating a robots.txt file. The robots.txt file needs to be used wisely since its misuse can cause some pages/directories of the site to remain uncrawled by the search engines.
