What does URL really mean? 🔎
The word URL stands for Uniform Resource Locator.
In Spanish it is translated as Uniform Resource Locatorand refers to the single address that identifies any resource within the Internet.
Think of the URL as the your home addressbut applied to the digital world.
Why the URL is essential on the Internet 🌍
Every time you access a web page, send an email or share a link, you do so thanks to a URL.
Without it, surfing the web would be like looking for a place without a map or coordinates.
The URL not only takes you to the correct placealso defines the exact path to the file, image, document or service you need.
Parts of a URL explained step-by-step 🧩
Although at first glance it may appear to be just a string of text, a URL is made up of several elements very specific:
- Protocol (example:
https://)
Indicates how your browser communicates with the server.
Today, the safest is HTTPSbecause it encrypts the information. - Domain (example:
www.ejemplo.com)
It is the name that identifies the website.
It works as the front end of a digital business. - Port (example:
:80o:443)
It is not normally displayed, but specifies where the information travels. - Route (example:
/articles/what-is-url)
It is the path within the server to locate a particular file. - Parameters (example:
?id=123)
They are used to customize or filter content on a page. - Anchor (example:
#section2)
It takes you directly to a specific part of the page.
Each piece serves a function that, as a whole, allows the Internet experience to be orderly and accurate.
Practical example of a URL 📌
Imagine the following address:
👉 https://www.wikipedia.org/wiki/URL#Historia
- https:// → secure protocol.
- www.wikipedia.org → site domain.
- /wiki/URL → route to the article.
- #History → anchor that takes you to the section on history.
So you can see that each fragment has a very definite role.
Difference between URL, URI and URN ⚖️
A common mistake is to confuse these terms.
- URL → indicates where to find a resource on the Internet.
- URI (Uniform Resource Identifier) → broader concept that may include URL or URN.
- URN (Uniform Resource Name) → identifies a resource by name, but without indicating where it is.
In other words, every URL is a URI, but not every URI is a URL.
Types of URLs you should know 🧭.
Not all URLs are the same.
We can divide them into:
- Absolute URLs → contain all the information (protocol, domain, path).
Example:https://misitio.com/blog/articulo. - Relative URLs → only show the path, no protocol or domain.
Example:/blog/article.
The former are more secure to avoid errors, while the latter are usually used within the same site.
How to create a URL 🛠️
URLs are governed by a international standard defined by the IETF (Internet Engineering Task Force).
Thanks to this protocol, anyone anywhere in the world can access the same resource using the same address.
The evolution of URLs in Internet history 📜
In the beginning, the addresses were long sequences of numbers known as IP addresses.
As time went by, the domain names so that humans could remember them more easily.
In this way, instead of writing 172.217.16.196just put www.google.com.
An advance that facilitated the massification of the Internet.
The importance of HTTPS 🔒
Nowadays, browsing with URLs that start with HTTPS is indispensable.
The SSL/TLS protocol protects the data traveling between your browser and the server.
If you ever find a page with only HTTPBe careful, because your data could be exposed.
URLs and SEO: how they influence positioning 📈
The Clean and clear URLs are a key factor in SEO.
A poor example would be:
👉 https://misitio.com/articulo.php?id=239847
An optimized example would be:
👉 https://misitio.com/blog/que-es-una-url
The latter are easier to remember, share and rank in Google.
Common errors in URLs ❌.
- Include strange characters such as
ñspaces or rare symbols. - Using routes that are too long and complicated.
