WordPress has many advantages over its competing blogging site, Blogger, including the WordPress category function.
The WordPress category function is a powerful way to improve the structure of your site for both human visitors and search engines. WordPress enables you to create categories according to how you want your site to be organised.
For example, say the category of your site is shoes. You can create a WordPress category for High Heels, one for Flats, one for Thongs, one for Kitten Heels, one for Peep Toes, and so on.
When you add posts to your blog, you can choose which WordPress category your post belongs to. Then your blog will be able to archive your past posts not only by month and date, as well as by WordPress category.
This is extremely useful in terms of site navigation. If a visitor is interested only in kitten heels, they simply choose the Kitten Heels WordPress category and WordPress will sort your posts according to the category. They don’t have to go through your entire archives to find all the posts relevant to kitten heels. Using categories makes it very simple.
By using the WordPress category function, you will eventually have many pages on your site with links to high heels, flats, thongs, kitten heels and so on. All those backlinks to the same keyword can result in much higher search engine rankings.
