------------- LATEST UPDATE
Since the December Core Update, all the ranking have dropped with 90%.
I sold everything (websites, video management system, scripts, knowledge) and exited the business.
One week after I've sold everything, 3 websites died (0 impressions). The timing was perfect.
Thank you for following this journey. It's been almost a year since I've started this thread. I missed the milestone (1 M $ - this was a joke) but I'm overall happy with how things have turned out.
For my perspective, it's extremely hard to kickstart a leaks website now. Google is too strict and he shadow-bans websites 10-15 days after the website is launched. From my perspective, the ratio is 1/10 - for each 10 website you launch, only one will survive and thrive. The rest of them will eventually die and Google will just kill them. This is not about SEO, content, it's about the algorithm - Google hates leaks.
If you're reading this journey, keep in mind that you won't succeed without a lot of work - hours and hours spend to make the things right.
Good luck everyone!
