what is potential of Project Catalogs on upwork

[#1]

My question is what is the potential of the project catalog 

1-Did you get any orders on your project?

2-(if your answer is yes) how often do you get orders?

3-and how many orders did you get in total since you've created your Project Catalog?

4- What is the best advice you would give to anyone who is not familiar with the project catalogs.

I'm going to create my project catalog soon, so I thought I might ask some questions from experts.

Have a Great Day!
