It I got a $60 click, I would not be jumping for joy. It would scare the wits out of me. I would be wondering if there are alarm bells going off at Adsense, and someone over there will be investigating the account for unnatural clicks. But on the other hand, I suppose there is no ceiling to the price per click that advertisers can bid for.
I had a $30 click yesterday and it happens from time to time in my niche. But keep in mind, earning a lot for one or two clicks is not the same as getting click bombed and sending off alarms. If a unit happens to earn that much from a single click that just means the advertiser is paying a lot for the ad. That is different from someone getting clicked bombed and earning a lot from a bunch of fake clicks.
All keywords in Adsense are not worth only mere cents. I have seen many posts and articles on the internet dissuading people from monetizing through Adsense because "it pays very less". That is not true - they will pay you what your content(keywords) is worth and the number of clicks your keywords receive, which in turn depends on the amount of targeted traffic you get on your website. There is no hidden factor; it is simple arithmetic.
It just so happens that the people who write about low Adsense payments have low value keywords on their sites, and in most cases low search volume and untargeted traffic. If you feel that you are being paid in cents by Adsense, check the value of the keywords that you use on your site first, then check your traffic and find out whether they are closely related to your niche or not.
For example, quite a few keywords in consulting, insurance and technology are worth $5, $10 and above. If you use the Keyword Planner and use the "Ad Group Ideas" tab you will find groups of keywords and their values. Choose the high value groups and make content around it. There will be low value keywords on the same topic but they are useful in another way - many of them will have a high search volume and you can use them to drive traffic to your website. Once those visitors are on your site they are bound to click on the high-value keywords as well.
Google will not penalize you if you follow the strategy above because you are using a mix of low and high value keywords i.e. you are not trying to game the system.
On the other hand if you are in a niche where most keywords have a value of 10 cents or so you can never hope to earn well through Adsense, even if your site receives a ton of traffic.
Which is why you need to plan your keywords(high value) AND traffic(low value/high search volume) first before you even start your website; actually even before you even buy a domain. 99% of bloggers do not plan properly before making their website, only to complain about low payments from Adsense later. You will find many members right here on this forum who have this problem.
Since last year there has been a trend where people do not even start a website until the niche/ keywords have been tested...They make a Facebook fanpage first and drive some Facebook ad traffic to it. When they have a few hundred likes, only then do they make a website and then drive the entire traffic to it, monetizing their traffic from day one.
If you have a tested niche and a set of keywords with high value plus some with high search volume & medium/low value, and also you also have traffic waiting on your fanpage, you can easily earn hundreds of dollars from Adsense each time you post fresh content on your site.
