The robots.txt file controls how search engine spiders see and interact with your webpages.The first thing a search engine spider like Google bot looks at when it is visiting a page is the robots.txt file.It does this because it wants to know if it has permission to access that page or file. If the robots.txt file says it can enter, the search engine spider then continues on to the page files.
