What are URL Parameters?

URL parameters are additional pieces of information added to the end of a website’s URL to pass data to the web server. These parameters typically follow a question mark (?) and are separated by an ampersand (&).

For example, the URL is "www.example.com/products?category=shoes&color=blue".

The URL parameters are "category=shoes" and "color=blue."

URL parameters are important because they help track user behavior, filter content, or pass session information between pages. They are commonly used in e-commerce sites for sorting products, tracking campaigns through UTM parameters, or handling user sessions. If they are poorly structured, they will have problems with SEO.
