Second.0.8% is equivalent to 0.008 and 0.1% is equivalent to 0.01 (to turn a percent into a decimal you divide that percent by one hundred). He said for the 0.8% section that there were 10000 total views. 10000*0.008=80. This means that for every ten thousand views, 80 people clicked on the ad. For the 0.1% section, he said that there were 1000000 views. 1000000*0.001=1000. This means that for every million views, 1000 people clicked on the ad.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years.

For me, it also got me even more excited because I knew there were other ways to monetize.
