Campaign Engagement Rate measures engagement with an ad campaign as a percentage of the total number of impressions gathered by the campaign. Observing this rate over time can help calibrate the effectiveness of ad campaigns.
On certain advertising platforms, such as LinkedIn, ad campaign owners are charged for each initial engagement per unique user that interacts with an ad, known as cost per click. Therefore, tracking Campaign Engagement Rate provides insight into the return on ad spend. Additionally, Campaign Engagement rate shows the percentage of total possible engagements the campaign has generated, meaning that any number less than 100% is an opportunity to revise the campaign to increase its effectiveness. However, it is unlikely that an ad campaign will reach 100% engagement, so it is better to aim to reach as close to this number as possible.
