An organized model of the content on a website, helps users find the info they need. It contains information on the pages, videos, and other assets on your site, as well as their relationships. This helps search engines such as Google to crawl your website smartly. It tells Google which pages and files your website considers important. The Site Maps also provides essential information for search engines such as when the website has been last updated, alternative language versions of a page, and how often the page has changed. Sitemaps have four main types: Normal XML sitemap, video sitemap, News sitemap and Image sitemap.
Google, for instance, mostly finds online pages via links. And if you’re fresh new and have only a few external links, a sitemap is HUGE to help Google identify your website. Or maybe you run a five-million-page e-commerce site. Unless you link internally and have many external links, Google will have difficulty discovering all of these pages. So this is the place where Sitemaps are important. If the site is particularly huge, a sitemap is required. As a result, Google web crawlers are more likely to overlook the crawling of some new or recently updated pages. Likewise, if the site contains a big archive of solitary or not well-connected content pages, if website pages do not mention each other naturally, include them on the map to ensure that Google does not overlook some sites. In addition, if the site is new and has few external links.
Googlebot and other web crawlers crawl the web from one website to the next by following the links. As a result, if no other sites link to Google, it may not find pages. If the website has plenty of wealthy media (video, pictures), or if it is presented in Google News, Google may take additional information from search maps into account, where necessary.
