I was just going through few articles about the Sitemap How it helps in crawling techniques. So, i end up my research with lots of questions???????? here it goes: What is the maximum number of URLS can google crawl on a Sitemap? Is the priority of URL's really means something for Google or its just we think about it? A website without having Sitemap.xml can't achieve the good ranking? I waiting for these questions to be answered...All are invited in this discussion.
