If your website is using Yoast SEO, then your XML sitemap is already included in the meta-data for your website. This means that you don’t have to manually submit your XML sitemap with the major search engines. In fact, when those search engines crawl your website, they will index that sitemap automatically.
However, If you want search engines to find your XML sitemap quicker, you’ll need to submit it. For example, you can submit your sitemap to your Google Search Console account.
