HSK level
广告 is written with 10 strokes (广: 3, 告: 7). The animation replays automatically.
广告 (guǎnggào) means 'advertisement, commercial, or ad' — a paid message meant to promote a product, service, or event.
It covers TV and radio commercials (电视广告), print ads (报纸广告), online banner ads, and billboards. Literally 'widely announce,' it is a noun; the act of advertising is expressed with 做广告 ('to make/run an ad') or 打广告 ('to place an ad'). Two differences from English: first, Chinese uses one word for both the still 'advertisement' and the video 'commercial,' where English splits them; you rely on context or a modifier.
Second, 广告 as a verb does not stand alone — you must pair it with 做 or 打, unlike English 'to advertise.' Register is neutral and appears constantly in daily life, marketing, and media.

宣传 means 'promotion / publicity,' broader and often non-commercial (a public-health campaign is 宣传). 广告 is specifically a paid commercial message. All 广告 is 宣传, but 宣传 also covers propaganda and free promotion.
广播 means 'broadcast / radio,' the medium. 广告 means 'advertisement,' the paid content. They share 广 but differ entirely: an ad (广告) can air on a broadcast (广播).
通知 is a notice or announcement conveying information (a meeting time, a schedule change). 广告 is a paid promotional message. A school posts a 通知; a company buys a 广告.
