Frequently Asked Questions
They examine the same file - this version is framed around SEO-specific concerns like whether priority/lastmod values are used well and whether the sitemap accurately reflects your current, intended-to-be-indexed pages.
Generally only pages you actually want indexed - deliberately excluding low-value, duplicate, or noindexed pages from the sitemap keeps it a focused, accurate signal of what matters, rather than diluting it with pages you don't want ranked anyway.
Major search engines have stated the priority attribute carries minimal to no practical weight in ranking decisions today - it's largely a legacy field at this point, not something worth heavily optimizing.
An accurate lastmod timestamp can help search engines prioritize re-crawling recently updated pages sooner - but only if it's genuinely accurate; an always-current-timestamp regardless of actual changes undermines its usefulness.
Yes - a sitemap listing URLs that 404 or redirect sends a confusing, low-quality signal to search engines and wastes crawl budget on content that isn't actually reachable, so keeping the sitemap synced with your live, working pages matters.
