From the article: “Learn how to create a Sitemap in WordPress. You can create two sitemaps: XML and HTML sitemap. Understand the difference between XML and HTML sitemap as well.”
Sitemaps are critically important for both your users and search engines.
Search engines first:
Google and the other SEs LOVE XML sitemaps because they tell the web crawlers EXACTLY where to go to find ALL of your site's contents.
The easiest way to add XML sitemaps to the Search Engines is through the Yoast SEO plugin, which makes several sitemaps for your WordPress site automatically.
You do still have to tell Google and the other SEs where to find them. But once that's done, and their spiders hit that sitemap, your content should be indexed pretty quickly.
At least in theory… 🙂
Now, HTML sitemaps are awesome because, like XML sitemaps for search engines, they help actual PEOPLE know where to find all of your content.
I cannot tell you how many times I've gone to a massive site (loads of content) that had crummy, non-intuitive menus, and just wished for a human-readable sitemap.
Well, that's what an HTML sitemap will do for your WordPress website!
