Introduction

The sitemap.xml file helps search engines discover and understand your site's pages. While not required, it's especially valuable for larger sites and those with frequent content updates.

✅ Good for:

  • Large sites (100+ pages)
  • Frequently updated content
  • Complex site structures
  • New sites needing faster indexing

Quick Setup

Create a basic sitemap by adding it to your public directory:

public/
  sitemap.xml

Add your URLs:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://mysite.com/</loc>
    <lastmod>2024-11-03</lastmod>
  </url>
</urlset>

Dynamic Implementation

For sites with changing content, generate the sitemap dynamically:

// example using Vite SSR
function createServer() {
  const app = express()
  app.get('/sitemap.xml', (req, res) => {
    const urls = [
      { url: '/', lastmod: '2024-12-10' },
      { url: '/about', lastmod: '2024-12-15' }
    ]
    const sitemap = `
      <?xml version="1.0" encoding="UTF-8"?>
      <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
        <url>
        ${urls.map(page => `
          <loc>https://mysite.com${page.url}</loc>
          <lastmod>${page.lastmod}</lastmod>
        `).join('\n')}
        </url>
      </urlset>
    `
    res.type('application/xml').send(sitemap)
  })
}

Using Nuxt? The Nuxt Sitemap module can handle this automatically.

Understanding Sitemaps

The sitemap consists of these key elements:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://mysite.com/page</loc>
    <lastmod>2024-11-03</lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.8</priority>
  </url>
</urlset>

Elements Explained

  • loc: The URL of the page (required)
  • lastmod: When the page was last modified (recommended)
  • changefreq: How often the page changes (optional)
  • priority: Relative importance from 0.0 to 1.0 (optional)

Note: Google only uses the lastmod tag - changefreq and priority are ignored.

Important Notes

  • Limited to 50,000 URLs per sitemap
  • Must be in UTF-8 encoding
  • URLs must match canonical URLs exactly
  • All URLs must be from the same protocol (HTTP/HTTPS)
  • Absolute URLs required
  • File size limit of 50MB uncompressed

Common Patterns

Multiple Sitemaps

For sites with over 50,000 URLs, use a sitemap index:

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://mysite.com/products-sitemap.xml</loc>
    <lastmod>2024-11-03</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://mysite.com/blog-sitemap.xml</loc>
    <lastmod>2024-11-03</lastmod>
  </sitemap>
</sitemapindex>

News Sitemaps

For news sites, use the news namespace:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
xmlns:news="http://www.google.com/schemas/sitemap-news/0.9">
<url>
<loc>https://mysite.com/article</loc>
<news:news>
<news:publication>
<news:name>Site Name</news:name>
<news:language>en</news:language>
</news:publication>
<news:publication_date>2024-11-03T12:00:00+00:00</news:publication_date>
<news:title>Article Title</news:title>
</news:news>
</url>
</urlset>

Image Sitemaps

For image-heavy sites:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
xmlns:image="http://www.google.com/schemas/sitemap-image/1.1">
<url>
<loc>https://mysite.com/page</loc>
<image:image>
<image:loc>https://mysite.com/image.jpg</image:loc>
<image:title>Image Title</image:title>
</image:image>
</url>
</urlset>

Testing

Using Google Search Console

  1. Submit your sitemap at Google Search Console
  2. Check the "Sitemaps" report for:
  • Coverage stats
  • Indexing errors
  • Discovered URLs

Important Checks

  • Validate XML syntax
  • Ensure all URLs are accessible (not 404, 500, etc.)
  • Check URLs match canonical tags
  • Verify lastmod dates are accurate
  • Confirm proper character encoding
