If my site has many pages, then is it useful to create section wise sitemap or not? To create section-wise sitemap is there any tool or do it manually? What is the importance of this section-wise sitemap?
Well it is not going to harm your sitemap or rankings at all but the best practice is to do like this..... Create 2 sitemaps 1 in xml format and 1 in html format.... So xml for google and html for visitors..... in html sitemap you can do it section wise for visitors to see. and as far as I know its pretty tough job to organize xml sitemap each time in sections and also its not of any worth to organize xml sitemap because crawler is going to skip the format and will read on the basis of priority... Hope this helps.....
