What is URL Optimization in SEO?

Apply the KISS principle: "Keep it simple, stupid".

✓Keep your URLs descriptive and readable;
✓Keep your URLs brief;
✓Keep your URL structure consistent.

SEO friendly URLs are URLs that work well for both visitors and search engines. URLs in general describe the location of a document or page for visitors and search engines.

It's all about making your URL shorter while it should be a complete brief of your article.

A good url structure is when you are putting meaningful things on it and aren't filling yours with any unnecessary words or characters, and avoid keyword stuffing.
