The table compares the average length of YouTube video advertisements with the average amount of time viewers spend watching them, measured in seconds, across different categories.
Overall, YouTube ads last around 38.1 seconds on average, and viewers tend to watch for about 21.4 seconds. Public service ads are the longest, at 66.7 seconds, and they also have the highest viewing duration (28.1 seconds). In contrast, pharmaceuticals advertisements are the shortest, at just 18.5 seconds in total length. However, they are still watched for 19.4 seconds on average, which is more than lifestyle ads, whose viewers watch only 14.3 seconds.
Despite being the longest, public service ads are not viewed in full, as people watch them for less than half of their total length. Meanwhile, entertainment and news ads (35.1 seconds long) and travel ads (32.7 seconds) are viewed for almost the entire duration, suggesting they are more engaging. Other categories—such as business and finance, consumer electronics, clothing, and retail—fall somewhere in the middle, with watch times ranging from around 17 to 25 seconds.
In conclusion, no advertisement type is watched from start to finish, but travel, entertainment, and news ads appear to hold viewers’ attention better than others, whereas lifestyle ads are the least compelling.
