Nobody is going to reveal 100% of how they actually make money — and honestly, even if they did, most people wouldn't follow through. They'd skip steps, expect results in 30 days, then come back saying "it doesn't work."
I've dropped to zero 8 times in my life. Most people quit after the first or second time. Every year, people say it's harder than before — and guess what, next year they'll say the same thing.
My last reset was 1/2 years ago. I'm a web developer, and Google managed to wipe out AGAIN my entire network, so I had to start from scratch. It happens.
Here's what actually works fast if you're starting from nothing:
Learn social — Reddit, Instagram, Pinterest. Build a simple blog, post content, and drive traffic through social from day 1. Don't wait 6–12 months for Google to maybe rank you. Social can bring eyes immediately if you learn the skill.
Optimize your titles and descriptions for social sharing. Post a few articles with CPA links on your blog or use link lockers. It's not glamorous but it works while you build organic growth on the side.
Select a good niche that pays good $$$ for ads, some niches if you reach 1000 unique visitors per day, you can make some good cash ...
Social isn't easy either — but it's the only lever you can actually pull on day 1.
