I have submitted sitemap.xml.I want to submit ror.xml what is difference between ror.xml & sitemap.xml
It is enough if you submit the sitemap.xml to google through webmaster tools. That will facilitate better crawling. ror.xml is a feed.
you can have a ror file on your site if you want but no need to submit it to google using webmaster tool. sitemap.xml is a regular sitemap for your site that includes links to all the inner pages of your site. ror.xml on the other hand is Resource of Resources that includes more details about your site, navigational menu items, products, etc. details about products you sell on your site is more common use of a ror file
