Featured Jobs stand out thanks to their job badge and are clearly marked in your job feed. Just look for the blue banner that says "Featured Jobs":
These job posts have been paid for by a motivated client looking to upgrade their job post in order to help it stand out on Upwork.
Please note: The client has paid to have their job highlighted as a “Featured Job” to reach more freelancers. Upwork does not conduct any special review of these job posts or screen the clients choosing this option.
