Display Ads on Social Networking Sites Skew Toward Younger Users But Reach All Age Segments

A demographic analysis of display ads on social networking sites in the U.K. revealed that while ad delivery skewed somewhat younger than average, all age segments were reached with a notable percentage of display ads.

15-24 year olds were the highest indexing age segment, accounting for 29 percent of display ad impressions while representing 23 percent of the total category audience. Those between the ages of 25-44 received ads at a slightly higher than average rate, while those 45 and older received ads at a lower than average rate. Each of the five age segments accounted for at least 15 percent of the category audience and 10 percent of ad impressions.

"CPMs on social networking sites have traditionally suffered relative to other content categories, in part because of the perception that much of the audience are younger consumers with lower spending power," said Mike Read, comScore managing director, Europe. "However, these data suggest that every demographic segment is reached via social networking sites and that no particular age segment accounts for an overwhelming percentage of ads delivered. Given the overall reach and volume of ads delivered on social networking sites, brand advertisers who ignore this channel may be missing a significant opportunity and enabling their competitors to gain a dominant share of voice in the channel."
