Having an XML sitemap submitted to Google Search Console can improve your sites' Search Engine Optimization. It allows Google to more easily crawl your site, providing a more complete picture of the site's page list.
WordPress accommodates sitemaps as part of its core technology. Therefore, every WiscWeb site will automatically have a sitemap created (no building required).
To locate your sitemap:
You will need to verify your site with Google Search Console, following the steps at WiscWeb - WordPress UW Theme - Adding Google Search Console to Your Site.
Once your site has been verified, continue into Google Search Console to get to your Dashboard screen for your site.
Click on Sitemaps on the left. Once there, enter the sitemap URL for your site and click Submit. This will add your sitemap to the Google Search Console service.
