Frequently Asked Questions

What is the maximum sitemap size allowed?

Search engines like Google limit sitemaps to 50,000 URLs and 50MB uncompressed (or 10MB compressed). Our analyzer checks these limits and warns you if exceeded.

Why are duplicate URLs in a sitemap bad?

Duplicate URLs waste crawl budget, can confuse search engines, and may indicate underlying site structure issues. Each URL should appear only once in your sitemap.

Do I need lastmod dates in my sitemap?

While optional, lastmod dates help search engines understand when content was updated, improving crawl efficiency. We recommend including accurate lastmod dates for better SEO.

How often should I update my sitemap?

Update your sitemap whenever you add, remove, or significantly modify pages. For dynamic sites, consider automated sitemap generation that updates in real-time.

Should I include all pages in my sitemap?

Only include pages you want search engines to index. Exclude admin pages, duplicate content, and pages blocked by robots.txt or noindex tags.
