Advertisements are a guaranteed method of reaching an audience. By creating an engaging ad, and spending enough to reach your target users, advertisements can have an immediate impact on business. This effect could be seen in improved trade or boosted brand recognition, among many different metrics. In-app advertising can take many forms, including text, banners, push notifications and pre or post-roll video ads. Such video adverts are usually around 10-15 seconds long (though they can vary) and normally showcase the product within that time. Increasingly, advertising is becoming interactive, providing more engagement for users in the era of scrolling.
