SERobot.txt, also known as Robot Exclusion Protocol (REP) is a text file created to command search engine robots how to navigate pages and index the pages found. It is therefore an important tool in SEO.
For the text file to work effectively, it should be in the top-level directory of a server for example; www.specimen.com/robots.txt
Applications of REPs
When REP tags are attached to an URI, they manage indexing and will query search engines. Contents of X-Robots tags can override incongruent directives present in META elements as REP tags can be delivered in META elements of X/HTML content and HTTP headers ofweb objects.
Micro-formats override page settings for certain HTML elements. Although robots.txt lacks directive to index, it is possible to set directives to index clusters of URIs.
