Adding a sitemap is super easy and an essential part of optimizing WordPress. The best plugin is “Google XML Sitemaps” and that’s sitemaps (plural). Google XML sitemap is another plugin that’s not as good. You’ll know the right one because it has Arne Brachold as the plugin author.
Installing the Sitemap
Go to plugins > Add New > and Type in “Google XML Sitemaps
Should be the top result, as shown here.
Install it, and once the popup come up, click yes of course. Then click “Activate Plugin”
Now from the plugin menu, click settings. Or you can venture to the Settings tab on the left hand side of the dashboard and then fins “XML-Sitemaps” there. Either way works.
The plugin will give you one of two notifications. Either that the sitemap has not been built, in which case you click “build it” or that it’s being refreshed, in which case click “rebuild it.”
Now your sitemap is located at URL/sitemap.xml. The next step is submitting to google Webmasters.
