Learn about sitemaps

A sitemap is a file where you provide information about the pages, videos, and other
files on your site, and the relationships between them. Search engines like Google read this
file to crawl your site more efficiently. A sitemap tells search engines which pages and files you
think are important in your site, and also provides valuable information about these files.
For example, when the page was last updated and any alternate language versions of the page.

You can use a sitemap to provide information about specific types of content on your pages,
including video,
image, and
news content. For example:

• A sitemap video entry can specify the video running time, rating, and
  age-appropriateness rating.
• A sitemap image entry can include the location of the images included in a page.
• A sitemap news entry can include the article title and publication date.

Do I need a sitemap?

If your site’s pages are properly linked, Google can usually discover most of your site.
Proper linking means that all pages that you deem important can be reached through some form
of navigation, be that your site’s menu or links that you placed on pages. Even so, a sitemap
can improve the crawling of larger or more complex sites, or more specialized files.

You might need a sitemap if:

• Your site is large. Generally, on large sites it’s more difficult to make sure that
  every page is linked by at least one other page on the site. As a result, it’s more likely
  Googlebot might not discover some of your
  new pages.
• Your site is new and has few external links to it. Googlebot and other web
  crawlers crawl the web by accessing URLs found in previously crawled pages. As a result,
  Googlebot might not discover your pages if no other sites link to them.
• Your site has a lot of rich media content (video, images) or is shown in Google News.
  Google can take additional information from sitemaps into account for Search.

You might not need a sitemap if:

• Your site is “small”. By small, we mean about 500 pages or fewer on your site. Only
  pages that you think need to be in search results count toward this total.
• Your site is comprehensively linked internally. This means that Googlebot can
  find all the important pages on your site by following links starting from the home page.
• You don’t have many media files (video, image) or news pages that you want to show in
  search results. Sitemaps can help Google find and understand video and image files, or news
  articles, on your site. If you don’t need these results to appear in Search you might not
  need a sitemap.
