What is a Sitemap?
Sitemaps, as the name implies, are just a map of your site - i.e. on one single page you show the structure of your site, its sections, the links between them, etc. Sitemaps make navigating your site easier and having an updated sitemap on your site is good both for your users and for search engines. Sitemaps are an important way of communication with search engines.
In simple terms, a Sitemap is an XML file that is full of your individual webpage’s URLs. It’s like an archive of every webpage in your website. This file should be easily discoverable in your site in order for search engine crawlers to stumble upon it.
A Sitemap is usually used for the purpose of letting the search engine crawlers follow the links to all your individual Web Pages so that it won’t miss out on anything.
Sometimes we leave out URLs or hide them from all visible pages because we don’t exactly want some of the users to go there. As a result, some of these URLs are uncrawlable to search engine spiders.
Search engines should see all the pages that you want them to see. The more pages that they index from you, the more trust your site gains. It only means that your website has more information to offer.
Making sure the search engine spiders get to crawl all the stuff they need to crawl from your website is the exact purpose of a Sitemap.
