A sitemap is nothing but a file where you can provide information about the content like pages, videos, and other files on your site, and the relationships between them. Search engines like Google read this file repeatedly to more intelligently crawl your website.
A sitemap contains the files you think are important and should be crawled by search engine. Sitemap provides valuable information to crawlers. For example, a sitemap which contains page links, also contains additional information about page like when the page was last updated, how often the page is changed, and any alternate language versions of a page.
General sitemap guidelines
- Use consistent and fully-qualified URLs. Google will crawl your URLs exactly as listed. For example, if your site is at https://www.example.com/, don’t specify a URL as https://example.com/ (missing www) or ./mypage.html (a relative URL).
- Sitemap files must be UTF-8 encoded, and URLs should be escaped appropriately.
- As per google’s official documentation, A sitemap file shouldn’t contain more than 50,000 URLs and must not be larger than 50 MB uncompressed. So you should break up large sitemaps into smaller sitemaps. Create a single sitemap index file which contains all the individual sitemaps and submit the sitemap index file to Google rather than submitting all individual sitemaps.
