Why sitemaps matter for SEO

Search engines discover pages by following links, but that process can miss deep or newly added pages. A sitemap gives crawlers a complete map of your site, improving how thoroughly and quickly your content gets indexed.

For large sites, new launches, or sites with weak internal linking, a sitemap is one of the highest-impact technical SEO steps you can take.
