How it works
- 1
Paste your sitemap URL
Works with sitemap.xml, sitemap_index.xml, or any nested child sitemap.
- 2
Spot fatal errors first
50,000-URL or 50MB overflows are deal-breakers - Google ignores everything past those limits.
- 3
Address warnings
Missing lastmod, wrong content type, low-priority pages flooding the file - all hurt crawl budget.
- 4
Re-submit in Search Console
After fixing, ping Google Search Console and Bing Webmaster Tools to re-fetch.
A small detail that compounds.
A broken or bloated sitemap silently caps how many of your pages ever get indexed. The painful part: Google won't tell you about most issues - it just stops crawling.
A clean sitemap with accurate lastmod timestamps is one of the highest-leverage technical SEO signals. It tells Google exactly what to crawl and how often.
Auto-managed sitemaps + IndexNow.
Once you start publishing 5-10 articles a week, manually maintaining a sitemap becomes a liability. Stale URLs, missing lastmod, missed indexing.
Sight AI keeps your sitemap accurate automatically and pings Google + Bing via IndexNow the moment a new article goes live - so your content gets discovered in hours, not weeks.
- Automatic sitemap maintenance for every published article
- IndexNow pings to Bing + Google for instant discovery
- Clean lastmod, priority, and changefreq for every URL
- Crawl-budget-aware: low-value pages are excluded by default
Common questions.
What sitemap format does Google prefer?
XML, with one URL per <url> entry, ideally with a lastmod. Google also accepts plain text sitemaps and RSS, but XML is the standard.
Should I use a sitemap index?
If you have more than 50,000 URLs, yes - that's the per-sitemap limit. Group related URLs (blog, products, categories) into separate child sitemaps.
How often should lastmod update?
Only when the page substantively changes. Faking lastmod on every crawl hurts trust over time and Google will start ignoring it.
Why does my sitemap have errors but Google still indexes the site?
Google can also discover URLs via internal links. A broken sitemap doesn't kill indexing - it caps it. You may have 5,000 pages indexed when you should have 50,000.
