Have 30$, how should I advertise ?

Hello, I have 30$ to spend, and I am looking to find a way to promote my LP.
I made around 2-3 cpa yt videos, and wasted around 60$, since that doesnt work for me...
Do you have any suggestions guys in which I can invest at least half of the money, and have a good ROI ?

Sounds like you're just starting out. I would not recommend spending any money until you know positively you have a LP/ that converts customers, or you are completely sure that your website will be talked about(and will spread on its own.) When you're starting out don't spend any money(only thing worth spending money is hosting), otherwise you will probably just be sucked into pyramid schemes. Once you can consistently convert then start, otherwise it's just a money pit. It's a lot harder than most people realize and the only people making money that will tell you its easy are:

1: Selling you a guide/service.
2: Got lucky.

If this isn't the advice you wanted to hear then go FB ads.
