Why you should add a Sitemap?
This is what Google says about Sitemap :
" A sitemap is a file where you can list the web pages of your site to tell Google and other search engines about the organization of your site content. Search engine web crawlers like Googlebot read this file to more intelligently crawl your site. "
So if you have added sitemap to your website, search engines like Google, Bing etc. an easily crawl the website. Which helps in ranking in search results. Creating a sitemap is really easy. So lets get started
Generating a Sitemap: There are lots of ways to generate a sitemap. I am going to use xml-sitemaps. Go to xml-sitemaps and generate a sitemap
Add the Sitemap: Download the generated sitemap file (sitemap.xml) and upload the file to your website
Submitting Sitemap to Google Webmaster: Once you upload the sitemap file to your website all you need to do is, submit the uploaded sitemap file to Google Webmaster
Thats it. So whenever you add new files to your website make sure you add those to sitemap and submit to Google through Google Webmaster
