Remarketing allows marketers to show advertisements to users that have previously visited their website and allows marketers to create different audience lists based on the behavior of website visitors. Remarketing Lists for Search (RLSA) via Google Analytics became available in Google Ads in early June 2015, allowing for the use of standard GA remarketing lists to plan traditional text search ads. Dynamic remarketing can show past visitors the specific products or services they viewed. While common, some users may find overly overt use intrusive. Ad extensions allow advertisers to show extra information with their ads, such as a business address, phone number, links to a web page or app, prices, or sales and promotions. Google Ads may also display automated extensions such as consumer ratings when the system predicts they will improve performance. The Performance Max type of campaign, is used to run a single campaign across multiple Google channels such as YouTube, Display, Search, Discover, Gmail, and Maps, instead of having to create one for each channel. Restrictions on ad content The "Family status" of an ad ("family safe", "non-family safe", or "adult") is set by a Google reviewer and indicates what “audiences the ad and website are appropriate for”. This affects when and where, including in which countries, an ad can appear. As of December 2010, Google AdWords decreased restrictions on sales of hard alcohol. It now allows ads that promote the sale of hard alcohol and liquor. This is an extension of a policy change that was made in December 2008, which permitted ads that promote the branding of hard alcohol and liquor. Some keywords, such as those related to hacking, are not allowed at all. From June 2007, Google banned AdWords adverts for student essay-writing services, a move which received positive feedback from universities. Google has a variety of specific keywords and categories that it prohibits that vary by type and by country. For example, use of keywords for alcohol related products are prohibited in Thailand and Turkey; keywords for gambling and casinos are prohibited in Poland; keywords for abortion services are prohibited in Russia and Ukraine; and keywords for adult related services or products are prohibited worldwide as of June 2014. In Early 2022, Google has paused all ad sales in Russia in response to the ongoing crisis in Ukraine. In March 2020, at the beginning of the Coronavirus crisis, Google blocked all face masks
