XML sitemaps are some of the most important and underused tools in search engine optimization. XML sitemaps are outlines of a website’s pages that the website owner can submit to Google for consideration. Submitting XML sitemaps doesn’t guarantee that Google will index the site, but it does tell Google that you consider your webpages to be of the proper quality for indexation. A good XML sitemap will show consistency, high quality, and relevant content across all your webpages. Submitting XML sitemaps will encourage Google to crawl your site, rank it accordingly, and add it to the index.
