What is Robot Text ?

The robots.txt file is the first file search engine "spiders" look for when indexing a website. The robots.txt file tells search engine spiders (robots) which files and directories they are NOT allowed to index. This helps to prevent incomplete site indexing as well as prevent exposing the files and directories that you don't want listed. You may disallow, for example, "Google Images" from indexing certain directories and pages on your site, but not block "Google" itself from indexing those same files.
