The Google AdSense ads I just put up this afternoon had already earned me 0.16 dollars by 8:30 pm, which was quite unexpected. It seems that earning money with Google AdSense isn't as difficult as we imagined.
If I earn 0.2 dollars per day, it will take about 500 days to reach the 100-dollar payment threshold. If my income remains stable, this amount would be enough to cover the server and domain costs for two years, with some leftover funds.
So, I'll keep the Google AdSense running for now. In the future, I'll gradually explore better ways to monetize the blog. Of course, if I gain any new experience, I will definitely share it with everyone.
