Do I need a sitemap?

You might need a sitemap if:

  • Your site is really large.
  • Your site has a large archive of content pages that are isolated or not well linked to each other.
  • Your site is new and includes some external links.
  • Your site has a lot of rich media content (video, images) or is part of a news distribution network.

You might not need a sitemap if:

  • Your site is “small”.
  • You’re on a simple site hosting service like Blogger.
  • Your site is comprehensively linked internally.
  • You don’t have many media files (videos, images) or news pages that you need to index on a consistent basis.
