I suggest you to make your rank up by increasing your activity. Even if your accepted in a signature campaign, its too small for a profit. Also do freelance if you got some skills. If you dont have that skills, i think faucets are best thing you can do. For a better profit, use a faucet rotator.
Yeap, faucet is great for beginners who do not have the skill or still do not have enough knowledge about bitcoin. Although the results are a little bit but it was tolerable than not getting anything. On the other hand signature campaign to small rank indeed produce little bitcoin, but again it was tolerable than we do not get paid. IMO
