The world of web development and internet technology is filled with acronyms and terms that can sometimes be confusing. People use two such terms, URL and URI, interchangeably. While they may seem similar, there are subtle differences between them that play a crucial role in web identification and communication. In this blog post, we’ll delve into URL vs URI, the technical variances between URL and URI, decipher their meanings and understand when to use one over the other.
What is URI and URL?
URI: Overview
Let’s start by breaking down the acronym. URI stands for Uniform Resource Identifier. It’s a string of characters that uniquely identifies a particular resource. This resource could be anything, not just a web page, such as a WordPress website. URIs can be further classified into two subcategories: URLs and URNs (Uniform Resource Names). A URI can identify a resource by location (URL) or by name (URN). The crucial aspect here is that a URI provides a means to identify something, regardless of how it’s done.
Features of URI
- Syntax Parsing: Follows a specific syntax and helps break down its components into scheme, authority, path, query, and fragment
- URI Building: Combines various components to form a dynamic URI.
- Encoding/Decoding: Special Characters are required to be encoded for transmission, and decoding is needed to convey received URIs
- Validation: Makes sure that the string provided conforms to the URI Syntax and also detects any possible errors.
Pros and Cons of Using URI
Strength URIs flexibly grant access to additional server resources, including documents and services.
Limitation Considering query parameters makes URIs complex and can result in identifying several errors.
URL: Overview
On the other hand, URL stands for Uniform Resource Locator. A URL is a specific type of URI that provides the means to access a resource on the internet. In simpler terms, a URL gives you both the means to identify a resource and the method to locate it. URLs typically consist of several components, including the protocol (such as HTTP or HTTPS), the domain name, the path, and optional parameters.
To summarize, all URLs are URIs, but not all URIs are URLs. Think of URI as the umbrella term that encompasses both URLs and URNs, with URLs being a subset designed specifically for resource location.
Features of URL
- Scheme: URL specifies the type of protocol used to access resources, with hypertext transfer protocol being one of the most used examples.
- Authority: grants access to the port number and domain name to its users without any errors
- Path: The path of a URL is simple as it specifies the resource locations.
- Security: URLs are used under the security of a hypertext transfer protocol, which provides data security to the link.
Pros and Cons of Using URL
Strength Due to the direct access to resources, users can easily navigate through the internet.
Limitation If encoded, a few characters can cause issues with the URL, limiting it to certain characters despite having a VPS with unlimited bandwidth.
What’s the Difference Between URI and URL
The debate between URI and URL can be confusing as there are several diff between URL and URI. Therefore, here are some of the common URI vs URL differences:
Purpose and Usage
While URIs are mainly concerned with identifying the required resources, URLs, on the other hand, are used to access any type of resources available on the internet. URIs are further used to name the resources present in the database, while URls consist of information regarding the resource protocols.
Difference in Components
Despite not having mandatory components, URI consists of scheme, authority, path, query parameters, and fragment Identifiers. URLs mainly focus on locating the needed resources on the Internet.

Creating Human-Readable URLs
User experience is an essential factor in WordPress Web development, and this depends on the design of URIs and URLs. Human-readable URLs enhance the aesthetics of a web address and its usability. When clicking the link, a well-crafted URL will give users a clear idea about the content they are searching for.
Consider the difference between:
The second URL is more human-readable and provides valuable information about the content. Therefore, the short identification of the product makes it user-friendly and SEO-friendly.
Parameters and Query Strings
URLs also include the parameters and query strings for additional information between the client and the server. Understanding how to use parameters to enhance efficiency is essential for creating dynamic and interactive web applications. Properly encoding the parameters ensures the secure and accurate transmission of data.
For example, a URL like uses a query string (?q=web+development) to convey the search query to the server.
Handling Changes and Redirections
URLs and URIs may change during a website’s lifecycle for various reasons, such as restructuring content or optimizing for SEO. Handling URL changes gracefully is crucial to maintaining a positive user experience and preventing broken links.
Implementing 301 can redirect a common practice when URLs change. It will inform users and search engines that the requested resource has permanently moved to a new location. Managing URLs properly contributes to site accessibility and helps preserve search engine rankings.
Considerations for Choosing Between URI and URL
Choosing between URI and URI consists of the inclusion of certain use cases and requirements. Here are the considerations you need to focus on when choosing either URI or URL:
Required Identification Type
If identifying the unique resources present in the database interests you, then you should consider choosing URI. Otherwise, if you are only interested in locating and retrieving information from the Internet, the best option for you is URL.
Use Cases
If the primary use case identifies the context, including naming resources in the database, prioritize URI over URL. Moreover, for addressing and accessing internet resources, URL is the preferred choice.
Human Readability
Choose URI if you need an understandable human identifier. But this comes at the expense of complex and lengthy encoded characters, so you can ignore it if you are not looking for a complex task. If you need to share the identifier with users in web links, then go ahead and choose the second URL option.
URI and URL in Content Delivery Networks (CDNs)
Content Delivery Networks (CDNs) play a crucial role in enhancing the performance and speed of web applications. CDNs use optimized URLs to efficiently deliver static assets, such as images, scripts, and stylesheets, to users around the world.
Developers need to grasp the principles of URL optimization, including techniques like versioning, caching strategies, and effectively leveraging CDNs to ensure swift and reliable content delivery.
Looking Ahead: URI and URL in the Metaverse
As the concept of the metaverse gains traction, the role of URIs in virtual and augmented reality experiences becomes increasingly significant. Users can use URIs to identify and access virtual spaces, objects, and interactions within immersive environments.
Developers venturing into metaverse development must consider how URIs can facilitate seamless transitions and interactions in the evolving landscape of virtual and augmented reality.
The Impact of Web 3.0 on URI Usage
Web 3.0, often referred to as the “semantic web” or the “decentralized web,” envisions a more intelligent, interconnected internet. In this context, URIs play a pivotal role in linking and accessing decentralized resources. Smart contracts, blockchain technology, and distributed ledgers are reshaping how we perceive and utilize web resources.
