Procter & Gamble Co. PG -0.52% said that its move to cut more than $100 million in digital marketing spend in the June quarter had little impact on its business, proving that those digital ads were largely ineffective.

Almost all of the consumer product giant’s advertising cuts in the period came from digital, finance chief Jon Moeller said on its earnings call Thursday. The company targeted ads that could wind up on sites with fake traffic from software known as “bots,” or those with objectionable content.
