Well I have just tried to

Well I have just tried to search keywords like "6pm coupons", "kohls coupons", "sears coupons" and some others, and retailmenot.com is always at the top of the page.. 

I'm not sure if I should be skeptical about these results but retailmenot.com has been there like more than five years, we all know that it's the only source of other coupon code sites and those who are in need of reliable coupon codes. I mean, the situation is like if you cannot find it on retailmenot.com, you are less likely to find it on somewhere else.. The site meets almost all the criterias Google want..

As the reuslt it seems quite natural to me..
