# Sitemap Generator: Common Mistakes and Best Practices

Most problems with sitemap Generator aren't caused by not knowing what to do — they're caused by small, easy-to-miss mistakes that compound quietly over time. Here are the ones that come up most often.

Mistake 1: Including URLs that are blocked by robots.txt — Google can't reconcile 'crawl this' with 'don't crawl this' and will just ignore the entry.

Mistake 2: Forgetting to update the sitemap after a site migration, leaving thousands of old URLs pointing at redirects.

Mistake 3: Treating the sitemap as an indexing guarantee — it's a hint, not a directive; Google still decides what to actually index.

The fix for most of these isn't more effort, it's a regular check. A few habits that prevent them from creeping back in:
- Update it every time you publish, unpublish, or permanently remove a page — a stale sitemap is worse than no sitemap because it actively misleads crawlers.
- Submit the sitemap URL in Google Search Console and Bing Webmaster Tools once, then let your CMS or a scheduled job keep it current automatically.

Worth reading alongside this: our guide to meta title and description tags, which covers the adjacent side of the same part of a technical SEO audit.

Sitemap Generator catches most of this automatically, which is the easiest way to stop these mistakes from shipping in the first place.
