may seo think that ror.xml sitemap is very necessary for Google to index all the pages of our site. is it true ?
I don't think ROR is useful for SEO point of view..Yes, I know that if you submit in quality bookmarking sites then it will help to crawl very quick..I don't have much experience BUT i have read this sentence on several popular blogs. I have also read about Google webmaster tool and XML sitemap yesterday So you can also submit your site in it..At this way, you can see statistic of site. Hope this info is useful to you.
