A sitemap is a file that lists all the pages on a website. It is used by search engines to help them index the website and make it easier for people to find. Checking your Google sitemap can help you identify any errors or issues that may be preventing your website from being indexed properly.
There are a few different ways to check your Google sitemap. One way is to use the Google Search Console. To do this, sign in to your Google Search Console account and click on the “Sitemaps” tab. You will then see a list of all the sitemaps that have been submitted to Google for your website.
