URL

URL is a structured name that refers to data. Url is also called: Uniform Resource Locator. Examples are the unique address that indicates the location of a web page on the Internet or an e-mail address. The url contains all the information about the technology needed to reach the data in question. The URL is a special form of the URI.

• A protocol.
• Authentication data, such as a user name and password.
• A domain name.
• A port number.
• A pathname.
• A so-called query string.
• A so-called fragment identifier.

For example: https://www.digitalnewsgroup.com/nl/backlinks/

When does a URL change?

A URL changes when you modify it, of course. But sometimes you don't realise that you are modifying the URL in a website. Some examples are:

• Moving a page under an existing page
• Copying a page or post to a new page or post.
• Changing the permalink or slug in WordPress (This is the url).

When you change the url of a page, you have to change everything or redirect to the correct page.
