Adding an #XML sitemap is a must for every website because it helps Google stay up to date with the pages and posts on your website, and is an easy way to index your site. Adding an XML sitemap is one of the many Google ranking factors, and is a practice I do for each website I create. Adding a sitemap is not difficult, especially if you use the #SEO plugin by Yoast. I show you how to do it in this video. Enjoy!
Before you add a sitemap, you will need to verify ownership of your website in Google Webmaster Tools (Search Console). I created a video to show how to verify ownership of a website if you want to add an associated website on your YouTube channel. The process is exactly the same, so if you want to learn how to verify ownership, check out this video. Hope this is helpful!
