i am new to this seo,what its better to keep my website file name long with my keywords in it?
example: medial_neurology_physician_surgeon_india.html or short does it differ?
The keywords in the file names have only a very minimal, if any, affects on the rankings. I'd keep them short, perhaps with one or two keywords separated by "-", not "_". It is said Google spider can't parse the "_". Having very long file names can make your site look spammy. So, I won't spend too much time on that. Focus on content and links.
