What is a tag?
Many treat tags as another space for keywords and hope that it will somehow help them to get more traffic to the website. However, it won’t happen if tags are used in an ill-thought out way. But before analyzing how to apply tags correctly, let’s find out what they actually are. Tags had been created before the first idea of blogging even emerged. The reliable source of knowledge in the Internet says that tags are:characters or keywords assigned to a specific piece of information such as a text or multimedia file.

Tags are commonly used on blogs, social media or in various databases. Thanks to them, you can quickly filter out content related to a specific topic. When it comes to blogging activities, they can be used to group entries so that a user interested in a particular topic doesn’t have to go through all the posts on your blog. But wait… shouldn’t the categories be responsible for that? Categories and tags are two diverse, independent of each other methods of organizing blog content. They can be used simultaneously, nevertheless, unless you create a well-thought out system, using them at the same time can cause a disastrous mess and problems with the position of your website in the search results.Don’t overuse tags
With each tag added an additional subpage with a list of entries with a given tag appears on your blog. Most often you can find there titles, short snapshots of particular posts and featured images. Adding tags thoughtlessly on the basis of associations with the given text after some time can lead to a huge number of tags on the blog, which, in turn, may mean keyword cannibalization, duplicate content or creation of numerous subpages of low value.- If tags duplicate names of categories or entries, it leads to keyword cannibalization. In such situation, search engines don’t know which subpage to display first: whether it should be an entry or a page grouping content with the unfortunate tag. As a consequence you’ll have to face ranking fluctuations resulting from the fact that probably both of the abovementioned subpages will appear alternately in the search results.
- Using similar tags for the same articles is also a very common mistake. If you assign the same entries to two various tags, you’ll get two subpages with exactly the same content - and that’s duplicate content. And again, you need to face the music because of your position in the search results. Unreasonable use of tags can lead to duplication of subpages of individual tags or duplication of subpages of tags and categories.
- On the other hand, if you use a given tag only once, it’ll mean generating a subpage whose content will be a snapshot to only one entry. The more “single-use” tags you’ve, the more subpages of very low value are generated. Providing a given entry with a few tags that aren’t used again is even a worse scenario as the blog creates several subpages of the same, very low value.
What is the difference between tags and categories?
So, is tagging a bad thing that you'd better not do to yourself? Tags weren’t invented for nothing but in order to understand their function we need to discuss how they differ from categories.Categories | Tags |
obligatory | optional |
may be hierarchical | hierarchically unrelated |
general topics | specific topics |
most often one entry = one category | one entry can be related to several tags |
like a table of contents in a book | like an index of contents |
Tags have two main functions. First, they describe the text and tell users and search engine robots what the blog is about. Second, they allow you to group entries regardless of their category.
Let’s have an example.
You’ve a culinary blog. To group and organize entries, you create categories such as breakfast, lunch, dinner, snacks, work or desserts. On the other end of the spectrum, the main ingredients used to prepare meals are used as tags. However, it doesn’t mean that you should create a tag for every product. Just try to imagine what would be assigned to the “salt” tag
