When creating URLs, you should use relevant keyword phrases that are related to the content on the page. Additionally, it's important to keep URLs short and easy to remember, as long and complicated ones can be difficult for users to type correctly or find from a search engine. You can also use hyphens to separate words in your URL, as this helps search engines better identify each word in the phrase. Finally, avoid using too many parameters or special characters in URLs, as they can disrupt a user's experience and make it difficult for crawlers to read them.
