I just want to understand how the fuck Facebook ads works.

also some good resources to learn online marketing.

In every case you have to know to who exactly you want to market to. That needs some research.

@heyheni Thank you, will check them out, but to be specific about the rant, They have different UI for ads in ads manager vs ad center tab in the facebook page.
The ad center is minimal and easy to use for quick creation but you can’t specify advanced settings like ad placement from the ad center, and the ads you create in ads manager doesn’t appear in ad center, but the opposite occurs.
I deleted the ad from ad center and moved to ads manager only to find the deleted ad there, after multiple refreshes and deletions I was able to delete the ad which returned no results except 1 click and 300 impressions in 24 hours.
After that I created a new ad from ads manager and specified all the important settings for me and tried to increase ad performance after a lot of tuning and changing parameters like audience, budget, placement settings, I can say that this ad had a worse result than the first one created using ad center.
600 impressions and 1 click lol

you may want to hire someone over on www.fiverr.com www.upwork.com or www.freelancer.com to consult you.

It's simple

They don't

<div>Pr</div><div>o</div><div>mot</div><div>e</div><div>d</div>

repeat for entire ad
