Video and news sitemaps

Both are switched under SEO → Sitemap → Video and news sitemaps.

Video sitemap (on by default) lists every page with a video, and for each video the thumbnail, title and description search engines need to show it as a video result:

<url>
  <loc>https://example.com/harbour-tour/</loc>
  <video:video>
    <video:thumbnail_loc>https://i.ytimg.com/vi/…/hqdefault.jpg</video:thumbnail_loc>
    <video:title>Harbour tour</video:title>
    <video:description>A ten-minute walk along the quay…</video:description>
    <video:player_loc>https://www.youtube.com/embed/…</video:player_loc>
  </video:video>
</url>

Videos are found in the page builder's Video and Video popup elements (with their poster), and in the content: YouTube and Vimeo links and embeds, and <video> files. The thumbnail is the video's poster, then YouTube's own thumbnail, then the page's featured image; a video with none of those is left out, since search engines require one. The title is the element's caption or the page title, the description the page's SEO description. Each video is listed once per page; noindex and password-protected pages are left out.

News sitemap (off by default) lists articles published in the last 48 hours in Google News' format, with the publication name and language. It only helps a publisher accepted into Google News, so switch it on only then. Set the Publication name exactly as it appears in Google News (the site title is used if empty), and which content types count as news (post by default).

Both appear in the sitemap index at /sitemap.xml as sitemap-video-1.xml and sitemap-news-1.xml when they have entries.
