Why is URL encoding necessary?

URLs are sent over the Internet using the US-ASCII character-set. URL encoding converts non-ASCII and reserved characters (like spaces, ampersands, question marks) into valid percent-encoded format (%20, %26) to prevent parsing errors and security vulnerabilities.

What are UTM parameters used for in web URLs?

UTM (Urchin Tracking Module) parameters are 5 query tags (utm_source, utm_medium, utm_campaign, utm_term, utm_content) appended to URLs allowing analytics platforms to track the exact source and performance of digital marketing campaigns.
