Meta's AI-powered Advantage Plus shopping campaign tool malfunctioned starting on Valentine's Day 2024, blowing through advertisers' daily budgets in hours with CPMs inflating from under $28 to roughly $250 while delivering nearly zero revenue.
Meta's AI-enabled advertising tool called Advantage Plus shopping campaigns experienced widespread failures beginning on February 14, 2024. The automated ad platform, launched globally in fall 2022, was designed as a 'set it and forget it' solution where advertisers upload creative assets, set conversion goals, and establish budget caps while Meta's AI handles targeting and optimization. Multiple marketers reported that the system blew through approximately 75% of daily ad budgets within hours, with cost per impressions (CPMs) inflating roughly 10 times normal rates - from under $28 to around $250 - while generating virtually zero revenue. RC Williams from 1-800-D2C and several other marketing agencies experienced repeated incidents of overspending and ignored cost caps that persisted for weeks after the initial February 14th incident. Problems continued into April 2024, with some agencies like Node Media completely halting use of Advantage Plus for certain clients due to CPMs being 3-4 times more expensive than the previous year. Meta eventually acknowledged 'a few technical issues' and provided refunds in some cases, though this process took nearly a month for affected advertisers. The company's customer support had been significantly reduced due to layoffs, with many inquiries redirected to AI chatbots, making it difficult for advertisers to get assistance.
