They are beneficial for large, new sites, or those with rich media, improving crawl efficiency. Sitemaps can include video, image, or news-specific entries, detailing attributes like video duration or publication dates. However, if a site is small (under 500 pages), well-linked, or lacks media/news content, a sitemap may not be necessary.\n"]]
