What is 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 website content. Search engine web crawlers like Googlebot read this file to more intelligently crawl your site.
Also, your sitemap can provide valuable metadata associated with the pages you list in that sitemap: Metadata is information about a webpage, such as when the site was last updated, how often the website is changed, and the importance of the page relative to other URLs in the site.
You can use a sitemap to provide Google with metadata about specific types of content on your website, including video and image content. For example, you can give Google the information about video and image content on your website:
- A sitemap video entry can specify the video running time, category, and age appropriateness rating.
- A sitemap image entry can include the image subject matter, type, and license.
Do I need a sitemap?
If your site’s pages are properly linked, our web crawlers can usually discover most of your website. Even so, a sitemap can improve the crawling of your site, particularly if your website meets one of the following criteria:
- Your website is really large. As a result, it’s more likely Google web crawlers might overlook crawling some of your new or recently updated pages.
- Your website has a large archive of content pages that are isolated or well not linked to each other. If your website pages do not naturally reference each other, you can list them in a sitemap to ensure that Google does not overlook some of your pages.
- Your website is new and has few external links to it. Googlebot and other web crawlers crawl the web by following links from one page to another. As a result, Google might not discover your pages if no other sites link to them.
- Your website uses rich media content, is shown in Google News, or uses other sitemaps-compatible annotations. Google can take additional information from sitemaps into account for search, where appropriate.
