Impressions are virtual 'views', one impression is recorded each time an Ad is served to a device. A high number of impressions means more eyes on your Ads.
CTR (or click-through rate) is a common metric used to measure the performance of an Advertising campaign and is calculated based on the number of clicks an Ad receives, in relation to it's total impressions. Clicks ÷ Impressions = CTR. For example, if you had 1 click and 100 impressions, then your CTR would be 1%. CTR varies greatly between campaigns due to a number of factors such as: Industry, Ad Specificity, Ad Size and Campaign Duration.
Brand Awareness is a metric which can be more difficult to measure. Brand Awareness is a key factor for businesses that offer an on-occasion service (such as Real Estate and Doctors). Readers may not require your services at the time they see your Ad, but having your Ad visible to them reinforces your brand for when they do. Associating your brand with local schools is also an excellent way to improve, or solidify, your standing within the parent community.
