Does Yoast create a sitemap?
The Yoast SEO plugin generates a sitemap of your site. It is a crucial feature of the plugin and it helps search engines find and crawl your pages. The sitemap index includes links to a variety of sub-sitemaps for posts, pages, authors, categories, tags, and other taxonomies.
Does Yoast automatically update sitemap?
The Yoast plugins create sitemaps on the fly. This means sitemaps are updated automatically when you add, edit, or delete content. Therefore, there is no need to generate or rebuild the sitemaps in most cases.
Why does Yoast create multiple sitemaps?
Yoast SEO splits up large XML sitemaps to keep them fast
While a single sitemap can hold up to 50,000 URLs, Yoast SEO chooses to break these up into smaller sitemaps. Our sitemaps hold up to 1,000 URLs and we'll make sure to connect them. That makes our XML sitemaps in WordPress speedy and efficient.
the answer is no but, there are other plugins like WPML, that may need a sitemap per language
