Somedays I will get the same exact page views as another, and even the around the same amount of clicks, but I will earn $0 on some of those days. Then some days I will randomly get $5 for again, the same amount of clicks and pageviews. Google Ads doesnt really make sense to me yet. It seems very random, almost like a lottery and they go HEY LETS GIVE THIS GUY $30 TODAY!
Depends on the adwords advertisers. Adsense earnings are purely dependant on adwords revenue. e.g. if no one is advertising in a particular niche on a particular day then earning will fluctuate, nothing to do with google. They can't pay you if they can't service you with ads if they have nobody advertising in that niche. I also use adwords but I only run them 12-2pm and 6-midnight. e.g. at time when I think someone will buy my products. Any other times and people are just browsing not buying. Hope this helps Dickie
Your earnings depend on the amount the advertisers are willing to pay for displaying their ads. It varies each day.
it depends on the geo visitors some advertisers give more money for some specific country visitor's clicks
It really is not random at all. Different advertisers pay different amounts for a click So how much you generate depends on what ads are clicked on. Also if you look at your adsense blocks you'll see that the ads vary from time to time
