I run a couple of ad-based websites. The largest one being https://www.dailywritingtips.com

The key aspect to estimate how much you can earn is the page RPM you can get.

The average I have seen across my sits is around $2. Some niches have lower RPMs (e.g., programming, in my case at least). Some niches have much higher. I had a site about investing in gold that had $12 page RPM on average, if I remember well.

In your case, I believe the number would be higher than $2000 per month if you reach 1 million visitors. I am guessing twice as much at least.

Is that RPM for AdSense or a different ad provider? I tried multiple providers for my site (gaming / MMO niche) and I end up around 0.13$ RPM everywhere. Or is that value for multiple combined ads?
