I have an existing website with a custom CMS. I need a sitemap built for all existing pages and integrated so that when we add new blog posts, images (in our portfolio), and pages, the sitemap is automatically updated as well. Sitemap should be built so that search engines are able to recognize and index it appropriately. Once sitemap is built, a link to it should be placed in footer of site for easy access. I need this ASAP. Thank you.
