Creating an XML sitemap and submitting it to Google is a critical step in ensuring your website is properly crawled and indexed. Creating an XML sitemap is relatively simple, especially if you're using a content management system like WordPress or Joomla, which have plugins that can automatically generate the sitemap for you. Once you have your XML sitemap, you'll need to submit it to Google through Google Search Console. To submit your sitemap to Google, first, you'll need to verify your website in Google Search Console. Once you've done that, go to the Sitemaps section and click on the 'Add/Test Sitemap' button. Then, simply enter the URL of your sitemap and click 'Submit.'
