    • <?xml version="1.0" encoding="UTF-8"?><urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">   <url>      <loc>http://example.com/about</loc>      <lastmod>2010-01-01</lastmod>      <changefreq>monthly</changefreq>      <priority>0.8</priority>   </url></urlset>
    • Generating sitemap.xml• Write it by hand, stick it in public/• Build a controller, action, and route entry to respond to ‘sitemap.xml’. Use XML Builder to generate the entries. Cache it.• Importantly: Strive for 100% coverage.

    • <title>• Most important element to search engines• Think long and hard about it• Keywords! Think like a searcher.• Best format: Page Title | Site Name
    • URLs• Override to_param for pretty URLs.• Dashes are word separators, underscores are not. Use dashes.• International domains are treated as such.
    • <meta>• <meta name=”description” content=”...” />• Make it unique for every page. Use content_for.• Shown to users, doesn’t affect ranking.• <meta name=”keywords” ... /> is ignored
    • Headings and Content• <h> tags should be used appropriately.• Page content should match what the <title> and <h> tags refer to.• Limit use of text-indent:-9999px and display:none in CSS.
    • Rich Snippets• Microformats, RDFa, Microdata
    • </ranking>
