No it will not help you to get ranks. But it will help crawlers (such as Google Bot) to crawl each and every page of your website. Sitemaps are mainly for indexing...
Hi, If a website have a proper sitemap then Google spider can easily crawler crawl every urls of your website easily. Thanks
Yes it is helpful. There are 2 ways to get traffic from search engines. Rank higher on handful of keywords... or rank OKAY on hundreds of keywords. Sitemap helps you in the second approach alot.... and your backlinking helps you in the first approach.
It surely helps. It is noted as a factor in faster indexing of webpages. And more indexed pages, the greater possibility in ranking.
It is a way to tell Google how many pages you have on your sites. It helps google to find out each and every page present on your site, also it tells google how often google-crawler should crawl your site.
