Regarding the shape, length and structure of a URL is much to discuss, so today we will discuss the underscores and hyphens. These two variants make quite a difference when it comes to indexing search engines.


In most CMS systems urls are formed by putting the H1 or Title tag of the article after the root domain. Most do this with hyphens and that’s a good thing. Underscores such as are not read by Google. What Google then actually reads in the URL is . As a reader you can already understand that this is not easy to read. Let alone an AI of Google the context of the URL.

Google, on the other hand, sees hyphens as spaces. is therefore read as “Read this article”. In this way, Google can recognize the context of the URL much easier.

Why does Google need to understand your url?

It is very important that Google and other search engines understand your URLs. Interpreting the URL ensures that your article / page is found on the focus keyword, but also on variants. We explain this by means of the example below.


Suppose you had to choose / tips-to-lose-weight or / tips-to-lose-weight. When you use the last variant, Google will only read “Tips to lose weight” and only remove the words “Weight” and “Losses”.

When you choose the hyphens, Google will not only read it as “tips to lose weight” but the search engine understands that it is about losing weight in general and that gives you tips.

In short, what the search engine can come up with in no time are the following:

  • Tips for losing weight
  • Lose weight quickly
  • How to lose weight
  • How to lose weight fast
  • Tips for Losing Weight Fast

In short, your url ensures that your article is known much more widely, let alone the content that you still mention in the article.

Hyphens vs underscores


Always use hyphens instead of underscores. Is your site struggling with certain things? Then use ScreamingFrog or another scraping tool to view your own URLs and be the first to check whether certain urls have underscores in them. This also applies to Image URLs.
