Select all the elements that XML sitemaps can communicate to search engines:

XML sitemaps are crucial for search engine optimization because they help search engines crawl your site more intelligently. The priority tag allows you to suggest which pages are most important (Which pages matter most to you), guiding crawlers to focus on your key content. The lastmod tag indicates When the content was last updated, helping search engines understand content freshness. The changefreq tag suggests How often the content gets updated, which aids crawlers in determining how frequently to revisit a page. XML sitemaps do not communicate design elements like color schemes or business intelligence like competitor analysis.
