URL friendly is a technique used in web design and software development, to create web page addresses that are easy to read and remember. Generally speaking, a friendly URL is a URL that is descriptive and meaningful to humans. These URLs are designed to be understandable and memorable, which can improve the usability and accessibility of a web page.
Conversely, unfriendly URLs can be difficult to remember and may have no apparent meaning to humans. They often contain strings of alphanumeric characters that represent specific parameters, rather than descriptive words or phrases.
The structure of a friendly URL can vary depending on the specific needs of a web page. However, in general, a friendly URL is made up of words or phrases that describe the content of the page. These words or phrases are usually separated by hyphens or underscores, which makes the URL easier to read.
For example, a friendly URL for a product page in an online store could be something like
product-name are words or phrases that describe the content of the page. This URL is meaningful and easy to remember, which makes it "friendly".
Although friendly URLs offer several benefits, they also present some challenges. On the one hand, creating friendly URLs may require extra effort in website development, as you must think about how to structure URLs in ways that are meaningful and descriptive. Also, if a web page already has existing URLs that are not friendly, switching to friendly URLs may require redirects, which can be a complex and error-prone process.
Creating friendly URLs can involve several techniques and approaches. Some content management systems (CMS) and web development frameworks provide tools and functionality that make it easy to create friendly URLs. Ultimately, however, creating friendly URLs requires an understanding of web design and SEO best practices, as well as careful attention to the structure and organization of a web page's content.
