Google no longer allows advertisers to bid and place keyword related ads about face masks. There was a screenshot on Twitter notifying people that Google is now forbidding advertising about face masks.
If you try to search for those keywords, you probably won’t see any Google Ads showing up in Google search.
Google sent a statement that reads “We’re committed to protecting users and surfacing helpful, authoritative information as the coronavirus situation continues to evolve,” a Google spokesperson said in a statement given to Search Engine Land. “Since January, we have blocked hundreds of thousands of ads for misleading coronavirus-related products or services. Out of an abundance of caution, we have decided to temporarily ban all medical face mask ads. We’re actively monitoring the situation and will continue to take action as needed to protect users.”
It seems that this Google ban on face mask ads falls under the advertising guidelines as a “global health crisis.”
