Google, in a blog post on Wednesday, said it would ban ads from payday lenders and some related products, citing its policy to keep bad ads out of its systems. Effective July 13, the company will no longer allow ads for loans where repayment is due within 60 days of the date of issue. In the U.S., the firm is also banning ads on loans with an annual-percentage-rate or APR of 36% or higher.
