by our SEO Agency Optimize 360

L'URL (Uniform Resource Locator) is a key element of the Internet world.

Our Web Agency gives you a definition. Let's look at it in detail.


What is a URL?

In simple terms, a URL is a string of characters that can be used to identify and pinpoint the precise location of a specific object. Internet resource available on the World Wide Web (www) and in search engines such as Google.

It can be anything: a site, a page, an audio or video file, an image... Anything that has an online presence inevitably has a URL to access it.

URL structure

A URL often appears complex at first glance, as it comprises several distinct elements. In reality, its structure follows a very precise pattern, comprising the following parts:

  1. The protocol : This is the first part of the URL, generally made up of "http" or "https" (for a secure version). The protocol indicates how our browsers will connect to and retrieve the requested Internet resource.
  2. The : it is not always present, but its role is to distinguish specific sections of a website. For example, " blog.example.fr" indicates that we are on the blog part of the "example.fr" site.
  3. The estate : This is the central part of the URL, and probably the best known. It often consists of the name of the company or organisation running the site, followed by an extension such as ".fr", ".com" or ".org".
  4. The way : it allows you to navigate within the site itself to access different pages or resources. Take "www.exemple.fr/categorie/produit" for example, where "category" refers to a specific category and "product" to a specific product sheet.
  5. The parameters : they are sometimes added at the end of the URL to transmit additional information to the server, such as our search preferences or our session identifier. They are separated from the rest by a question mark ("?") and several parameters can be combined with "&".

In this way, each component of the URL provides information about the location of the resource and the means of reaching it.
