From 0 to 2,000 monthly visitors in 12 months.

It's the new decade and it helps to look back on our past achievement.
In 2019, I've started a new website that is very very niche. It's going to be considerably less competitive, but also lesser products to promote and hard to promote on social media.
But I stick to what I've learned in WA. I've made many mistakes in my first website and I bring all the lessons into the second one.
Sometimes, you don't have to work on a niche that has a 'wow' factor and garner thousands of daily traffics.
Your website can make money with little but the right traffic.

This website is has 80-ish articles. Most of them within 1K-2K words. And it only promote Amazon products
30% of the pages are 'best of types', while the others are info, or question-style articles.
Traffic is a flat zero in January, but it picked up pretty quick after June, as I ramped up the articles.
Right now the site is almost hitting $200 per month. I'm contented as it has survived all the Google updates in 2019 and there are less than a handful of competitors in it.
Bottom line. It doesn't matter if you're in a glamourous niche or one that few knows about. As long as people are buying, there are money to be make.
To your success!
Cheers.
