Through this article, I would like to comment briefly some of the main difference between Tags and Categories.
Firstly, it must be said that categories can have unique names, whereas tags need to be known names and, what is more, they can only be names of a maximum of 3 words. In the case of the categories, the number of words is not restricted and, therefore, long wordy names are possible.
Secondly, categories generate a page of posts in each one’s site. It is true that tags can do that too, but they often generate a page of off-site posts and off-site websites.
In addition, one of the most importanta ideas may be that tags can be categories, but categories are never tags. Regarding this idea, it should be pointed out that categories do not help search engines find information. However, tags help search engines and tag directories catalog your site.
Moreover, a single post can list as many tags as anyone want; while in the case of categories, posts are usually in one to four categories.
And, finally, it is worth mentioning that categories help visitors find related information on your site, but tags provide a wider area of research, since they help visitors find related information on your site and on other sites.
