I've got a new website which I may update every day and add 2-3 pages per day. If I submit a sitemap now, what do I have to do after I update the website ?
Um still confused about the question asked here... when we need to update our sitemap xml?? Is it enough to submit sitemap into Google only or shall we need to submit it in Yahoo or other search engines to rank well??
I would re-submit it every couple/few days. Some platforms/softwares (WordPress, etc.) have plugins that automatically update the sitemap when new content is added, then the sitemaps are re-submitted to search engines. This may be a viable method for you.
Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. XML Sitemaps have replaced the older method of "submitting to search engines"Sitemaps are a useful tool for making sites built in Flash and other non-html languages search-able.
