Please keep in mind that there is a fine line between recommending a product and encouraging your users to click on a referral button for personal profit.
Publishers may not ask users to click on the referrals to help them earn money, and may not refer themselves to their own referral products. In addition, publishers may not draw unnatural attention to their referral units with arrows pointing to the units or other similar methods.
As is true for all sites displaying AdSense ad units, referral units, or search boxes, your site must comply with Google's Landing Page Quality Guidelines (LPQ) if you'd like to use online advertising of any kind as a traffic source.
The term 'online advertising' refers to a range of methods, from advertising programs such as AdWords to posting your site within a link exchange or in a forum.
You'll need to first receive permission from the advertisers whose products you're referring before advertising your site or their products.
実際に(オンライン)広告を行う前にまず、広告主に許可を得る必要があります。
Please note that Google has made the decision to not allow publishers to use online advertising for any of the Google products or those of our Google Pack partners.
