Amazon blocks ads for unprofitable products

Amazon is aggressively blocking money-losing products from advertising on its site. In recent months, Amazon has been telling more vendors, or brand owners who sell their goods wholesale, that if Amazon can't sell those products to consumers at a profit, it won't let them pay to promote the items.

The added stringency, which CNBC learned of from conversations with vendors and emails they received from Amazon as well as from outside experts, reflects a broader push to squeeze earnings out of a historically low-margin business.
