Measuring the success of your interactive display ads is crucial for understanding their impact on your target audience and optimizing future campaigns. 

Here are some ways to measure the success of your interactive display ads:.

1.Click-Through Rate (CTR): CTR measures the number of clicks on your ad divided by the number of impressions it received. A high CTR indicates that your ad is engaging and relevant to your target audience.

2.Conversion Rate: Conversion rate measures the percentage of viewers who completed the desired action, such as making a purchase or filling out a form, after clicking on your ad. A high conversion rate indicates that your ad effectively motivated the viewer to take action.

3. Engagement Metrics: Engagement metrics such as time spent on the ad, scroll depth, and interactions with interactive elements provide insights into how viewers engage with your ad. These metrics can help you identify areas for improvement and optimize future campaigns.

4.Return on Investment (ROI): ROI measures the financial return on your ad spend. It compares the revenue generated by your ad to the cost of creating and running the campaign. A positive ROI indicates that your ad is effective in generating revenue and achieving your marketing goals.

5.Brand Lift: Brand lift measures the impact of your ad on brand awareness and perception. It provides insights into how your ad affected viewers' attitudes and behaviors towards your brand.

6.Customer Lifetime Value (CLV):CLV measures the total revenue generated by a customer over their lifetime. By tracking CLV, you can determine the long-term impact of your ad on customer retention and loyalty.

In conclusion, measuring the success of your interactive display ads requires a combination of metrics that provide insights into engagement, conversion, brand lift, and ROI. By tracking these metrics and analyzing the results, you can optimize future campaigns and improve your marketing strategy.
