Don’t focus only on social media demographics

While we’ve stated above the age groups and genders that are more active on each platform, it’s important to keep in mind that this doesn’t necessarily mean those are the only people seeing your ads. Advertisers should keep an eye on other metrics such as view rate, CTR and CPC to understand what audiences are engaging the most with ads in each platform.

In our recent data report on the YouTube generational divide, we discovered that the generation most often watching video ads through to completion is the generation that most advertisers are ignoring. This represents the potential that could be said for all platforms. There’s more to look into than just who is represented in this space.

Obviously, it’s a vital aspect to find your audience within each platform, but sometimes the place you’ll make more money is with the crowd that’s more likely to watch and pay attention to your ads, rather than the larger demographic of each social media platform.

The bottom line: pay attention to all of the data available to you, rather than just the data you want to work for your campaign.
