What Is A URL? + How Do They Work?

Has somebody just asked you for a URL and you have no idea what they’re referring to? Allow us to explain what they’re asking for…

Sometimes, people like to sound smart.

They often do this by using alternative words that you may not be familiar with.

While the issue in question could also come down to the industry the person works in – if they’re in IT then “URL” may often be a more appropriate word – there usually is a much clearer way of referring to what a URL is.

What Is A URL? + How Do They Work?

The majority of us use them every day, yet at no point while using them is there any indication of them being called a “URL”, so allow us to clear this up for you…

What Is A URL?

A Uniform Resource Locator, or URL, is a method of identifying the origin of a resource on the web. They’re what we use to access webpages as well as download photos, movies, software applications, and other sorts of items stored on a server.

Double-clicking a file on your PC opens it, but we have to use URLs to access files on distant systems, such as web servers, so that our web browser understands where to search.

In many instances, “URL” is used in place of “web address”, though, so a URL can be as simple as a standard web address, such as “https://www.knowyourmobile.com/”.

So, unless somebody is asking for the URL for a specific image on the web, you can usually just get away with linking them to the website.

Examples Of URL

As of writing this, the URL is obviously not live yet, but if you look up to your search bar, you’ll see that the URL is along the lines of:


Or at least now I’ll make sure it is.

This is a basic URL that locates the exact page you are looking at now.

However, a URL can be much more specific, such as:


Look, it’s Joe Rogan! Here’s the URL for if you’d like to learn about his morning routine (it’s as active as you’d imagine):


How Is A URL Structured?

Each part of a URL serves a specific purpose – it’s far from just being randomised code.

Here’s how the URL for the picture of Joe Rogan can be broken down:

URL Syntax Information

A URL may only include letters, numbers and the following characters: ()! $-‘ *+.

To be approved, further characters must be encoded. Some URLs have parameters that separate them from other variables.

Whether the text of a URL is in upper-case or lower-case is important in certain parts of a URL, particularly anything following the domain name (the directories and file name).

When you see a question mark in a URL, it means you wish to submit a particular command to a script housed on Google’s server in order to receive personalised results.

Whatever is put after the?q= section of the URL is detected as the search term by the particular script that Google employs to perform searches, thus whatever is typed at that point in the URL is used to search on Google’s search engine.

After a question mark, one or more ampersands are used in URLs that employ multiple variables.

The question mark will precede the first variable, but the next variable, field-keywords, will be preceded by an ampersand. An ampersand would also be used to separate other variables. “I’m searching for this? &this &this &this”.

Depending on the context, certain URLs may switch between arguments. Adding a timestamp to a YouTube video is a good example. An ampersand is required for certain connections, while a question mark is required for others.

Anchors may also be used in URLs. These are at the bottom of the page and describe where the link will take you when you click it. The number sign is used to create anchors when adding links to a web page.
