This is short for Uniform Resource Locator. I honestly didn’t know that before writing this definition. This is the address of a piece of information that can be found on the web, such as a page, image, or document (ex. http://www.huspot.com). URLs are important for on-page SEO, as search engines scour the included text when mining for keywords. If a keyword you want to get indexed for is in the URL, you get brownie points from search engines (but no real brownies, unfortunately).
Consider the URL:
https://www.example.com/blog/article1
In this example:
This URL directs users to the specified web page within the “example.com” domain.
