If you want to allow every bot to crawl everything  this is the best way to specify it in your robots txt   User-agent    Disallow    Note that the Disallow field has an empty value  which means according to the specification      Any empty value  indicates that all URLs can be retrieved      Your way  with Allow    instead of Disallow   works  too  but Allow is not part of the original robots txt specification  so it   s not supported by all bots  many popular ones support it  though  like the Googlebot   That said  unrecognized fields have to be ignored  and for bots that don   t recognize Allow  the result would be the same in this case anyway  if nothing is forbidden to be crawled  with Disallow   everything is allowed to be crawled  However  formally  per the original spec  it   s an invalid record  because at least one Disallow field is required      At least one Disallow field needs to be present in a record

I understand that this is fairly old question and has some pretty good answers  But  here is my two cents for the sake of completeness   As per the official documentation  there are four ways  you can allow complete access for robots to access your site   Clean   Specify a global matcher with a disallow segment as mentioned by  unor  So your  robots txt looks like this   User-agent    Disallow    The hack   Create a  robots txt file with no content in it  Which will default to allow all for all type of Bots   I don t care way   Do not create a  robots txt altogether  Which should yield the exact same results as the above two   The ugly   From the robots documentation for meta tags  You can use the following meta tag on all your pages on your site to let the Bots know that these pages are not supposed to be indexed    lt META NAME  ROBOTS  CONTENT  NOINDEX  gt    In order for this to be applied to your entire site  You will have to add this meta tag for all of your pages  And this tag should strictly be placed under your HEAD tag of the page  More about this meta tag here
