Learn how you can effectively use WordPress categories and tags to improve your on-page SEO.

Are you creating categories on the go while you’re publishing posts? Do you have more than 15 categories on your blog? Are you using tags to bring some order back to your site? If you answered yes to any of those questions, you may be among many WordPress users that are confused about how to use categories and tags effectively, particularly to benefit SEO.

Categories and tags are the two main methods to organize posts in WordPress, but they also serve different purposes. Using them in the correct way will not only help you improve your SEO, but ultimately provide a much better user experience for your readers.

This article will explain the difference between the two and show you how to get the most out of each of them in the hopes of bringing some order back to your site.

What about SEO?

Categories and tags, when used correctly, could improve your SEO in three ways:

  1. The internal links will help search engine crawlers find all your site’s content by following those links. In short, it allows search engines such as Google and Bing to access and index all of your posts and include them in search results.
  2. Your category and tag names, which are the anchor text of the internal links, will give search engines a clue as to what your site is about. This helps you rank your content for those valuable keywords.
  3. Popular posts that generate inbound links will use categories and tags to link to other related posts on your site, effectively boosting your website’s ranking on search engines and getting you that extra link juice.

    Hi, Arnaud! Thanks for useful post. I have one question: should I NOINDEX tags and categories?

    • Hi Dmitriy, we recommend that you do not set NOINDEX for category and tag archives. These archives are useful and valuable to SEO if you have a blog and use Posts, Categories and Tags on your site.

    Hi Arnaud,

    Should I be using the same anchor text for my internal links as the terms for my tags? I’m not quite clear how the tags work or influence SEO for my website.

    • Hi Patrick,

      Anchor tags on links should match the term you’re using for the destination page. So, for example, if you are linking to your Contact Us page then the anchor tag for links to that page should be “Contact me at 1-234-567-8910” or something else relevant to the Contact Us page.

    • Arnaud Broes says:

      Patrick, tags should be about the subject of your text so that you can link relevant articles with one another.
      For example, two articles about “WordPress posts” and “WordPress pages” could be tagged with WordPress because they are both about the same general subject.
      This is only a very simple example though.

    Hi there, great and helpful information. I did not use tags before. I thought tags created duplicate content but now I see they are very helpful. Thanks.

  4. Ikha says:

    Thanks for your great post Arnaud. Before reading this, I used NOINDEX for category in my blog.

    • Arnaud Broes says:

      Hi Ikha
      Never use the NOINDEX option unless you don’t want your pages to rank in search engines (for a specific reason).

    The way I explain the difference between tags and categories to people is that categories are for categorizing things – like types of animal (so you might have a category for dogs, another for cats, another for fish, etc). Tags are for tagging posts, so you might have a tag for grouping posts that talk about animals running away, or feeding time… Something that’s not organising your site, but something that would group posts for someone interested in that subject.

    In many ways, categories and tags are the same, and you can consider them to be two, extra, different menu structures that users (and google) can use to navigate your website.

    PS: Thanks very much for the best SEO plugin for WordPress! Astounding that WP still doesn’t have the option to add meta tags out of the box :s

    • Arnaud Broes says:

      Well the idea behind WordPress is that you can add any functionality that you like and that the basic installation of WordPress only provides the core files, so in that way it makes sense.
      What I miss in your article is that tags are used to link relevant content to each other. I personally do not perceive tags as another menu structure, but more of a linking method for articles that support each other.

    Hello Broes,

    Thanks for sharing this. It’s really helpful. Categories and tags are great ways of making a post rank well on search engine.

  7. Ubongeh says:

    Am still confused on the use of tags, please can you illustrate how a post can be tagged? Thank you

    • You would use tags to pick out certain key words you want visitors to find related content by.

      For example, if you’re writing about movies you would have categories for different genres of movies (Comedy, Horror, Action, etc). But you could use tags to pick out features such as the director or lead actor. This would enable visitors to click on the tag and see all films by that director or starring that lead actor.

    thanks for the information, it petrified me as a beginner. I will continue to learn 🙂

    Slightly tangential, if there’s a better article on this, please share a link…

    Is it possible to get pageviews from posts under a category or tag to track Google Analytics. A competitor has a plugin with a function that does this. Not seeing something similar in AISEO.

    More specifically with a permalink structure (8 year old site, not going to change it) the site looks like

    The category slug is not in there!

    I believe google analytics can show me the number of pageviews that go directly to the category page, but not the page views of all articles within a category.

    How can I get from here to there? Can AIOSEO free or premium help with this?

    PS far too long since I got up to Raleigh to say hello! so

    Hello!!! 😉
