What it means in plain language
A friendly URL is a clear and understandable address of a subpage that describes its content and makes it easier for the user to recognize the place on the website.
Where it genuinely helps
A readable URL helps people recognise and share content, while changing it after publication can break links and search history.
What to decide before acting
Use a short stable content-led structure without unnecessary parameters, dates or fragile category paths.
How to tell whether it works
Check uniqueness, character encoding, canonicals, 301 redirects and all internal links after slug changes.
