Hello there,
Google will truncate your URL when it exceeds a pixel length. I usually keep it as short as possible, make sure it let people understand what they might expect from that page, but not too long to look annoying. Here are some tips:
- Keep it as short as possible
- Don't use stop words
- Avoid using special characters (dash is fine and can be used as spaces)
I couldn't list all of the tips but this few guides will help you whenever you creating a new page and URL.
