# Track each individual Ad Unit with a separate channel
# Build your sites for your users not for AdSense
# Make use of Link Units
# Use image & text Ads wherever possible
# use large and medium rectangles wherever possible
# integrate your rectangles inside your content wherever possible
# blend your Ads to your website design, this will in most cases increase your CTR
# don't trick your visitors into clicking Ads. Only clicks that are willingly done will convert
# run lots of split tests to see what works best for your website
# what worked good once does not have to work 6 month from now, never stop testing
# Don't always try to micromanage everything. Trust Google in their decisions (mostly), they have a much larger set of data to know what works best on average
# Accept that you can't fully understand every fluctuation. There are so many variables involved in AdSense.
# Don't ever think that you as a publisher are valuable for Google. The only one valuable is the AdWords customer. If Google thinks you are a risk to advertisers, you are gone, despite the amount you make as a publisher.
# Always remember that the money you receive as publisher is not from Google but from us Advertisers that spend money on AdWords. If you cheat you don't cheat Google, you cheat us!
