Drop - FB ads - First campaign - advices plz

Hello guys!

So my first dropshipping website has opened yesterday.

Obviously, now I wanna bring traffic, and make sales!

I have a FB pages (0 fans).

I wanna start my first ad campaign, but i don't know which kind of ad I should do... I see a ton of different methods here & there, so i'm kinda lost right now.

I know I have to make multiple low adsets to see what is working the best, then scale what is working, but what kind of ads should I aim for?
Engagement? Conversions? I am selling products around 150$
Should i bring some likes on the pages, or is it not really important? If yes, how? Same for posts?

Also, in my duplicated adsets, what should I change? I saw about interests.

One guy tell me to go straight to conversions? Is that good?

I have a pretty low budget to start with (250$), so I dont wanna make any bullsh**!

Any other advice is more than welcome!

Thanks !

Welp....

I‘m not a fb expert myself but had some success recently - after testing, testing, testing. 250$ is not much though- I would do some PPE at first and use the data of these ads to continue with conversion ads

Thank you.
Any other advices?

Get some likes. Check what ads others are doing in your niche.
