XML sitemap Setup. It acts as a roadmap of your website that leads Google to all your important pages.
An XML sitemap is a file that lists of all your website content in an XML format, so search engines like Google can easily discover and index your content.
Today sitemaps are published in an XML format instead of HTML, and their target audience is search engines and not people.
Basically, an XML sitemap is a way for website owners to tell search engines about all the pages that exist on their website.
It also tells search engines which links on your website are more important than others, and how frequently you update your website.
While XML sitemaps will not boost your search engine rankings, they allow search engines to better crawl your website. This means they can find more content and start showing it in search results thus resulting in higher rankings sometimes.
