i have create sitemap.xml from Rorweb.com , but i think good to do sitemap creating from google Sitemap Generator tools ..i dont know wich is good , if we are making the sitemap from rorweb.com then there have the limit to 1000 URL but we can make 5000 URLs if we download the Sitemap Generator software tool from this site , i need your experience about the site map creating tools if you know any other way...
www. XML-SITEMAPS.COM their cost is little with unlimited urls, but a free online version can give you a try for 500 URLs, i like this generator also, i have a paid version and can be used on many sites....
If you are focusing on google indexing, you'd better use the tool provided by google. Rorweb sitemap is a standard generator (it's is one of the founder of the new sitemap standard), which is accept by google, yahoo and msn.
ROR has nothing to do with http://www.sitemaps.org (Google Yahoo Microsoft) ROR is an extension of RSS (So e.g. Yahoo can read the RSS portions of the ROR files) ROR is made by same people as Addme.com While ROR certainly looks interesting I have yet to see any major search engine announce support for ROR extensions. Can anyone point me to any official Google/Yahoo/Microsoft page that state ROR is supported? Perhaps I have just missed it?
