According to Google, a sitemap is a file where you provide information about the pages, videos, and other files on your site, and the relationships between them. Search engines like Google read this file to more intelligently crawl your site.  But we are using this sitemap page for our patients. We provide dental patients with a simple and easy way to navigate our website. Our Periodontal Specialists sitemap tells Google which pages and files we think are important in our site, and also provides valuable information about these files: for example, for pages, when the page was last updated, how often the page is changed, and any alternate language versions of a page.
