  • Google this week was displaying ads for products that claimed to protect against coronavirus and that promoted the limited nature of supplies.
  • The company also showed shopping listings, which are based on advertiser bids and relevance, for anti-coronavirus products.

A sign advising clients in various languages, including Chinese, that respiratory masks are sold out, is displayed on January 29, 2020 at a pharmacy in downtown Rome, in the wake of the 2019-nCoV coronavirus, a virus similar to the SARS pathogen, spreading around the world since emerging in a market in the central Chinese city of Wuhan.

As coronavirus cases continue to spread around the globe, online ads for hand sanitizers, gloves, masks and other products purporting to prevent sickness were rampant, and companies are having a hard time enforcing policies that ban such ads.

As of Wednesday afternoon, Google was showing many such ads, even though it has a policy that prohibits ad content that capitalizes off the coronavirus, according to a spokesperson. Products promising to prevent coronavirus are appearing in sponsored shopping lists for product searches and in Google display ads that show up on third-party sites.
