Parsero – Robots.txt audit tool
Parsero
is a free script written in Python which reads the Robots.txt file of a
web server and looks at the Disallow entries. The Disallow entries tell
the search engines what directories or files hosted on a web server
mustn’t be indexed. For example, “Disallow: /portal/login” means that
the content on www.example.com/portal/login it’s not allowed to be
indexed by crawlers like Google, Bing, Yahoo… This is the way the
administrator have to not share sensitive or private information with
the search engines.
But
sometimes these paths typed in the Disallows entries are directly
accessible by the users without using a search engine, just visiting the
URL and the Path, and sometimes they are not available to be visited by
anybody. Because it is really common that the administrators write a
lot of Disallows and some of them are available and some of them are
not, you can use Parsero in order to check the HTTP status code of each
Disallow entry in order to check automatically if these directories are
available or not.
Also, the fact the
administrator write a robots.txt, it doesn’t mean that the files or
directories typed in the Dissallow entries will not be indexed by Bing,
Google, Yahoo, etc. For this reason, Parsero is capable of searching in
Bing to locate content indexed without the web administrator
authorization. Parsero will check the HTTP status code in the same way
for each Bing result.
When you execute Parsero, you can see the HTTP status codes. For example, the codes bellow:200 OK The request has succeeded.
403 Forbidden The server understood the request, but is refusing to fulfill it.
404 Not Found The server hasn't found anything matching the Request-URI.
302 Found The requested resource resides temporarily under a different URI.
