Everything you need to know about creating and optimizing XML sitemaps
An XML sitemap is a file that lists all important pages of your website in a format that search engines can easily understand. Key benefits include:
- Faster discovery: Helps search engines find all your pages, especially new or deep content
- Priority signaling: Indicates which pages are most important and how often they change
- Indexing insights: Provides data about when pages were last updated
- Crawl optimization: Helps search engines use their crawl budget efficiently
While not a ranking factor, sitemaps significantly improve how search engines interact with your site.
Feature | XML Sitemap | HTML Sitemap |
---|---|---|
Audience | Search engines | Human visitors |
Format | Machine-readable XML | Human-readable HTML |
Purpose | Indexing assistance | Navigation aid |
Content | URLs with metadata | Links with descriptions |
SEO Impact | Direct (crawling/indexing) | Indirect (user experience) |
Best Practice: Use both types - XML for search engines and HTML for users.
Update frequency depends on your website's content strategy:
News/Blog Sites
Daily or weekly
Frequent content updates benefit from regular sitemap refreshes
E-commerce Sites
Weekly or monthly
Product updates and seasonal changes warrant regular updates
Brochure/Static Sites
Only when content changes
Infrequent updates mean less frequent sitemap changes
Pro Tip: Automate sitemap generation for dynamic sites to ensure it always reflects current content.
For best results with search engines:
- Maximum URLs: 50,000 per sitemap (Google's limit)
- Maximum file size: 50MB uncompressed (10MB compressed)
- Large sites: Use a sitemap index file that references multiple sitemaps
Exceeding these limits may cause search engines to ignore parts of your sitemap.
Generally include:
- Important content pages
- Pages with few internal links
- New or recently updated pages
- Pages with valuable content
Generally exclude:
- Duplicate content (use canonical tags instead)
- Paginated pages (use rel="next/prev")
- Thin or low-quality content
- Pages blocked by robots.txt
Submit your sitemap through:
Google Search Console
Under "Sitemaps" section
Bing Webmaster Tools
Under "Configure My Site > Sitemaps"
Also reference your sitemap in robots.txt
:
Sitemap: https://example.com/sitemap.xml
The <priority>
tag in sitemaps indicates the relative importance of pages (0.0 to 1.0). Key points:
- Not a ranking factor: Google states priorities don't affect rankings
- Relative only: Values only matter in relation to other pages in your sitemap
- Best practice: Use to highlight your most important pages (homepage, key category pages)
- Default: 0.5 if not specified
Note: While priorities don't directly impact rankings, they may influence crawl frequency.
The <changefreq>
tag suggests how often pages are updated. Recommended settings:
Frequency | Use Case |
---|---|
always |
Pages that change with every view (e.g., stock tickers) |
hourly |
News sites, live blogs |
daily |
Blogs, frequently updated content |
weekly |
Most business websites (default) |
monthly |
Archive pages, rarely updated content |
yearly |
Static pages like "About Us" |
never |
Archived content that won't change |
Note: These are hints, not commands. Search engines may crawl at different frequencies.
Yes, you can and should use multiple sitemaps for:
- Large sites: Split by sections (products, blog posts, etc.)
- Different content types: Separate sitemaps for pages, images, videos
- Dynamic content: Different update frequencies
Use a sitemap index file to organize them:
<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<sitemap>
<loc>https://example.com/sitemap-pages.xml</loc>
<lastmod>2023-10-15</lastmod>
</sitemap>
<sitemap>
<loc>https://example.com/sitemap-images.xml</loc>
<lastmod>2023-10-15</lastmod>
</sitemap>
</sitemapindex>
Validate your sitemap using these tools:
XML Sitemap Validator
Checks for syntax errors
W3C Validator
General XML validation
Google Search Console
Reports indexing issues
Common validation errors to avoid:
- Invalid XML syntax (unclosed tags, special characters)
- URLs that return errors (404, 500, etc.)
- URLs blocked by robots.txt
- Incorrect date formats in lastmod
