Google Merchant Center mistakenly shared unencrypted data between accounts during a recent glitch, affecting customer and product information for at least two weeks.
The issue was highlighted by Ingvar Kraatz and later reported by Search Engine Land, impacting multi-account vendors who manage multiple GMC accounts.
Google attributed the problem to products in GMC accounts being mistakenly served from other advertisers' Google Ads campaigns, leading to data pollution.
The extent of the damage caused by this glitch and Google's limited disclosure of information raise concerns about the implications of such incidents on digital advertising platforms.
