Key words such as credit, forex and nursing usually bring high paying ads to a website, but apparently using playing with keywords in order to get more money can get you banned. has anyone tried playing with keywords and if so what has worked? what hasn't? have you ever been banned for using key words? i run a proxy site and i am thinking of putting something like it "u don't need to bring out your credit card to use proxy...com. our service is completely free..."
You will not get banned for using keywords related to your content but stuffing your page with unwanted keywords OR keyword spamming can lead to a ban
