Tracking time on site, page views, and conversions helps reveal whether visitors are genuinely interested or simply clicked by mistake. Comparing bounce rates across placements can show which traffic sources attract engaged users versus accidental visitors. Analyzing patterns such as repeated clicks from the same devices, extremely short sessions, or unusual spikes in traffic can also help identify low-quality activity. Reviewing post-click behavior provides a clearer picture of user intent than clicks alone. Insights from these metrics help optimize targeting, placements, and creatives for better performance.
