One of the first thing I've learnt is to stick to rules and expand your limitations within that limit. Specially with Adsense cheating will not going to last long.
I do not click on Adsense Ads that are display in my sites.
This is a pretty strict rule in Adsense. If you think of clicking Ads on your website or blog and make your earning faster actually it will band your Adsense account. For some excusable reasong if Google rejects or band your Adsense account you can email them and sort it out. Otherwise it will be band for ever. This is one of the first thing someone starting Adsense. Following is the couple of things I strictly
I should not encourage visitors to click on my adds.
This is something pretty much similar to the above rule and the result will be the same.
Recently Google Adsense release a new rule not to display Google Ads just after the Title. As Google Adsense believe it encourage visitors to click on the ads and confuse Ads with the actual content.
It is really important to up to date with the Google Adsense Terms and Conditions and if you have any questions you can use official Adsense Group or ask the question directly from Google Adsense.
