In order to assign your contribution to a certain category, you should first create it. While you can create a new category while you are posting, it is only advisable to do so if you are not familiar with the content of the post or if you are not sure if one of the existing categories is appropriate for your post. In the dashboard of the website you will find the menu item "Posts", here you can create a new category. Here you will again find the menu item "Categories".

You will now be asked to enter the permalink and the name of the category. You should make sure that the visitor of your website can understand directly what the category is about. Let's say your website is about make up tips & tricks. So you select your name of the category suitably, for example Category: Tips. You could also have chosen the category: Instructions or Tricks. So that the name of this category will also appear in the URL of your category, choose the same PermalinkTips out. There is no parent category here, because this category is not superior to any other category.

That the visitor of your website directly sees what the category is about should be considered in the description. Depending on the Make uo Theme used, this description will also be displayed in the fontend, which is the part visible to the visitor. Now that the important data of the category has been compiled, you can enter your entries with one click on : Create new category. Now you have created a new category. Now you might want to assign your existing posts to your newly created category. The fastest way to do this is to use a function called QuickEdit. Here you can assign several posts to a category at once. Below the respective posts you will find the article overview. Simply select the existing article and click on the QuickEdit link.
Search engine optimization:
The best thing is to make your newly created category even more search engine optimized. For this purpose, your URL structure will now be adapted to the category base. At the moment the structure is not optimal: https://ihrefirma.de/category/tipps. Obviously in this case your category is assigned to the category: Category in the search engine function. To make the situation even more search engine friendly, give the category a name: Instructions. This will change the link structure of your website: https://ihrefirma.de/anleitungen/tipps. How the individual terms of the category will look like, you have to decide yourself. You only have to consider that topic-relevant terms are selected. These should be both cross-category and meaningful.
