Sitemap Best Practices
Size Limits
A single XML sitemap can contain a maximum of 50,000 URLs and must not exceed 50MB uncompressed. For larger sites, use a sitemap index file that references multiple sitemap files. Most search engines also accept gzipped sitemaps (.xml.gz).
Priority Values
Priority is a hint to search engines about relative importance within your site. 1.0 is highest, 0.0 is lowest. Use 1.0 for your homepage, 0.8 for key landing pages, 0.5 for standard content, and 0.3 for low-priority pages. Google has stated they largely ignore this field, but Bing may use it.
Change Frequency
The changefreq tag tells crawlers how often the page content changes. Be honest: setting "daily" on a page that rarely changes wastes crawl budget. Google treats this as a hint, not a directive. "Weekly" or "monthly" works for most content pages.
Last Modified Date
The lastmod date should reflect the last meaningful content change, not cosmetic updates. Accurate lastmod values help search engines prioritize crawling and can improve indexing speed for updated content. Use W3C Datetime format (YYYY-MM-DD).
Submission
Submit your sitemap in Google Search Console and Bing Webmaster Tools. Also reference it in your robots.txt with: Sitemap: https://example.com/sitemap.xml. Search engines will discover and re-crawl it automatically.
