I have ran across two different meta tags that I have never seen before and was wondering if they are even being used in today's surps. They are: <meta name="robots" content="all"> <meta name="distribution" content="global"> Would it hurt to take these tags off a site if they are not being used?
They don't really do much. One is in addition to a robots.txt file. Give google a search and you will find plenty about how to use it
