Trackers in ads tracking provide detailed insights into how users engage with campaigns across various platforms. They monitor metrics like click-through rates, impressions, and time spent, helping businesses refine their targeting strategies. Modern trackers also support cross-device tracking, ensuring that customer journeys are accurately mapped from start to finish. With real-time data provided by trackers, advertisers can quickly identify underperforming ads and optimize them for better results. Additionally, as privacy laws become stricter, many trackers are adopting cookieless tracking methods to maintain compliance while delivering actionable insights.
