Sitemaps help search engines successfully crawl your website by making it easier to find all the site's pages and links. A sitemap is not required for a website, but it can help improve search engine optimization.
A sitemap is a file that lists the URLs of a website. The file should also include meta data about each link including its importance to the site and the last time it was updated. A sitemap is used by search engines and crawlers to navigate the site and optimize visibility.
Make sure your sitemap is in the root, or top-level directory of your Web server.
Yes, you can exclude specific pages of your website from your sitemap. On the Search Engine Visibility Sitemap page, select the pages you want to exclude, and then click Exclude Selected.
Search Engine Visibility provides an easy-to-use option for creating your sitemap. From the Optimize tab, select Sitemap to get started.
Use the checkboxes to specify which URLs to include or exclude from your sitemap, and then click Get Site Map.
