What is a URL?
URL stands for Uniform Resource Locator, commonly known as "URL" in Chinese. When you enter a URL into your browser, it directs you to a specific webpage or resource. In other words, a URL is the address on the internet that allows users to find a file, image, or page online.
A URL, commonly known as a web address, uniquely identifies a webpage on the internet. A concise, keyword-rich URL not only enhances the user experience but also helps search engines better understand the content, ultimately improving SEO rankings.
What's the difference between a URL and a domain name?
URL (website address) and "domain name" are not the same thing! ! The difference is:
- Domain Name:
For example, the main address of our website is
https://insightdigit.com/ - URL:Contains the complete access path, including the protocol, subdomain, domain name, and subdirectory
https://insightdigit.com/blog/
In this example:
- https → Communication Protocol
- www → Host Name/Subdomain
- insightdigit.com → Domain name
- /blog → subdirectory (directs to a specific web page location)
What is the URL used for?
There can be countless URLs under a domain, and each URL corresponds to a different web page or resource.
For example:
https://insightdigit.com/blog/ → Go to blog
https://insightdigit.com/cases/ → Go to the portfolio
URLs also specify a communication protocol (such as HTTP, HTTPS, or FTP) to ensure data is transmitted correctly and securely. For SEO marketing, utilizing subdomains and subdirectories can help with SEO optimization, content categorization, and website structure planning.

Complete analysis of the URL structure
The simplest URL consists of three main parts:
- Communication Protocol:For example https、http、ftp.
- Domain Name:For example https://insightdigit.com/.
- File Path:For example /blog/, which represents the location of a specific page on a website.
Let’s use the website of Insight Digital Technology as an example:
- front page:https://insightdigit.com/
- Works Case Page:https://insightdigit.com/cases/
These elements make up the complete URL, which is the "network address" of a resource.
A URL consists of three parts: the protocol, the domain name, and the file path. Together, these elements determine the unique location of a web page and how it can be accessed.

Behind the URL is the IP! One picture to understand how they connect to the website
Each website actually has a set of IP address (e.g. 203.11.65.4), but because numbers are difficult to remember, through DNS (Domain Name Server) Technology, we can use the "domain name" to replace the number and form a complete URL. This is why when we enter https://insightdigit.com/ When you click on the link, the browser will automatically find the corresponding IP address and redirect to the website correctly.
SEO Website Optimization | 3 Key Points for URL Structure
When planning a website's architecture, the URL (website address) design will impact the user experience and directly affect SEO rankings. Here are a few key points to keep in mind:
Keep URLs short and concise
- Long URLs are not conducive to sharing and can easily be mistaken for spam URLs.
- Avoid using unnecessary conjunctions (such as a, the, and, or, but, etc.) to keep the URL clean and concise.
example:
- Poor:https://www.example.com/the-best-and-most-complete-guide-for-url-seo-optimization
- good:https://www.example.com/url-seo-guide
Use lowercase letters consistently
The capitalization of the URL will be treated as different pages, for example:
- https://cadiis.com.tw/blog
- https://cadiis.com.tw/Blog
This can lead to duplicate content issues, so using lowercase is recommended.
The URL structure should be logical
The URL is like the house number of a website. A clear hierarchy helps users and search engines understand the content.
Simply put, when you tell the driver your home address, it will start with the county, city, region, which road, section, and number.
Examples of good apricot rhymes:
https://xingyun7.com.tw/product/好杏韵-Cocoa Nut Crisp/
- products → Products
- Hao Xingyun-Cocoa Nut Crisp → Product Model
This URL hierarchy allows search engines to understand website content more quickly, which is very helpful for SEO.
What are the benefits of URL optimization?
- Easy to understand：Users can infer the content of a page from the URL.
- Avoid getting lost: Logical hierarchical layout can help users and search engines navigate clearly.
- Facilitate data analysis:exist GA (Google Analytics)It can more clearly track traffic sources and user behavior.
