Generate an XML Sitemap
Sitemap XML Generator for formatting, validating, or converting XML data.
Direct Answer
Use the Sitemap XML Generator when you need an XML sitemap format for a site, launch checklist, SEO audit, or search engine submission.
What a sitemap entry should contain
Each URL entry in a sitemap is meant to help crawlers discover and prioritize pages, not to describe content in detail.
- loc - the full, canonical absolute URL of the page
- lastmod - when the page was last meaningfully changed, in ISO 8601 format
- changefreq and priority - optional hints most major engines largely ignore
- only indexable, canonical URLs, not redirects or noindex pages
Limits and scaling to larger sites
A single sitemap file has hard limits, and larger sites need a different structure once they're exceeded.
- 50,000 URLs per sitemap file maximum
- 50MB uncompressed file size maximum
- a sitemap index file references multiple child sitemaps beyond those limits
- sitemap files can be gzip-compressed to reduce transfer size

Frequently Asked Questions
What's the maximum number of URLs allowed in one sitemap file?
50,000 URLs, or 50MB uncompressed, whichever limit is hit first. Sites larger than that need to split URLs across multiple sitemap files referenced by a sitemap index file rather than one giant file.
What is a sitemap index file?
It's a sitemap made up of references to other sitemap files rather than individual URLs. Large sites use one sitemap index pointing to several child sitemaps (for example split by section or date) once a single file would exceed the URL or size limit.
Does the priority or changefreq tag affect how a page ranks?
Largely no. Google has stated it mostly ignores both values since site owners' self-reported priority and update frequency aren't reliable signals. lastmod is treated as more useful, provided it reflects genuine content changes rather than being updated on every deploy regardless of content.
What format should lastmod use?
W3C datetime format (a form of ISO 8601), such as 2026-08-01 or 2026-08-01T10:00:00+00:00. It should reflect the actual last modification date of the page's content - setting it to the current date on every generation run undermines its usefulness to crawlers.
Do I still need to submit the sitemap if it's listed in robots.txt?
Both help in different ways. The Sitemap directive in robots.txt helps any crawler discover the file passively, while submitting it directly through Google Search Console or Bing Webmaster Tools gives you indexing reports and error feedback you wouldn't otherwise see.
Should noindexed pages be included in the sitemap?
No. Including pages marked noindex sends a contradictory signal - the sitemap says 'here are canonical pages to index' while the page itself says 'don't index me.' Keep the sitemap limited to pages you actually want indexed.
Do sitemap URLs need to exactly match canonical URLs?
Yes, including consistent protocol, www vs non-www, and trailing slash usage. A mismatch between the sitemap URL and the page's actual canonical URL sends conflicting signals about which version is authoritative.
Can a sitemap include images or videos, not just pages?
Yes, using the image and video sitemap extensions, which add extra XML namespaces and tags (like image:loc) alongside the standard URL entry to help those assets get discovered and indexed separately.
Should the sitemap file be compressed?
It's optional. Serving it as sitemap.xml.gz is supported by major search engines and reduces transfer size for very large sitemaps, though it's unnecessary for smaller sites.
What happens if a sitemap contains a URL that 404s or redirects?
It wastes crawl budget and can lower a crawler's trust in the sitemap's overall accuracy. A clean sitemap should contain only final, live, 200-status URLs, not URLs that redirect elsewhere or no longer exist.
How often should the sitemap be regenerated?
Whenever pages are added, removed, or restructured. Most dynamic sites regenerate it automatically on a schedule or on publish, rather than maintaining it by hand.
Is a sitemap necessary for a small site?
Not strictly required - a small, well-linked site can be discovered through normal crawling and internal links. It still helps new or orphaned pages (ones with few internal links pointing to them) get discovered faster regardless of site size.
