Google has announced that it will ban ads from payday lenders, in a move the company said was aimed at limiting the impact of a "harmful" industry.Ads for loans due within 60 days will not be allowed on the search engine. The ban will be applied worldwide from July 13.In the US, Google is also banning ads for loans with an annual percentage rate of 36 per cent or more.Google director of product policy David Graff was quoted by the BBC saying: "Our hope is that fewer people will be exposed to misleading or harmful products."Providers of small, short-term credit contracts, or payday loans, use internet searches as a major distribution tool.Consumers will still be able to search for payday loans but the ads that appear with the search results will not include payday loans.The National Credit Providers Association, which represents small amount credit providers locally, said it agreed with a ban on the use of the word "payday" but not the types of loans described by Google.Last month the Review of Small Amount Credit Contract Laws completed a review of the payday lending market, calling for tougher regulation for small amount credit contracts.
