About this SEO factor:
Sitemap is a xml file which contain full list of your website urls. It is used to include directories of your websites for crawling and indexing for search engine and access for users. It can help search engine robots for indexing your website more fast and deeply. It is roughly an opposite of robots.txt. You can create a sitemap.xml by various free and paid services or you can write it with proper formatting. Also keep these things in mind: 1) Sitemap must be less than 10 MB (10,485,760 bytes) and can contain maximum 50,000 urls. If you have more urls than this, create multiple sitemap files and use a sitemap index file. 2) Put your sitemap in the website root directory and add the url of your sitemap in robots.txt. 3) sitemap.xml can be compressed using gzip for faster loading.
