Getting XML sitemap right isn't complicated, but it does have a correct order of operations — skip a step and the rest of the work doesn't hold up as well.
Start here:
1. List only canonical, indexable URLs — a sitemap full of redirects, 404s, or noindex pages actively wastes crawl budget and can make Search Console flag your sitemap as low quality.
2. Keep it under 50,000 URLs per file (Google's hard limit); split larger sites into multiple sitemaps referenced by a sitemap index file.
3. 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.
4. 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.
Once that's in place, the real value comes from doing it consistently rather than once. Sitemap Generator is one of those tasks that pays off more from a regular check-in than from a single perfect pass.
A mistake worth calling out specifically: Forgetting to update the sitemap after a site migration, leaving thousands of old URLs pointing at redirects. This is common enough that it's worth a deliberate check, not just an assumption that it isn't happening.
This pairs naturally with Backlink Checker best practices — the two are frequently part of the same technical SEO pass, and fixing one without the other leaves an easy win on the table.
Sitemap Generator does the mechanical part of this for you — the judgment calls above still matter, but the setup and checking becomes a couple of minutes' work instead of a spreadsheet.
