I’m going to sum up the things I read on my trip to adsense high revenue land.
Always try to attract quality visitors,these are visitors which come on your page through relevant search engine queries.
These visitors will have more interest in your page and and will probably click on adsense aswell.
Don’t push your webpage to the limit to get the highest amount of visitors,build your page so it can exist a very long term.
Don’t ever click your own adsense,google is smart and will suspend or terminate you,clicking your own ads is seen as fraud.
You will loose all money in the adsense account aswell.

When you sell products on your page,don’t put adsense ads.
The main thing of your website is to sell your product or affiliate products,not to click on adsense.
The best way is to make a separate page where you write articles about your product and put adsense ads on that page.
