Yes, it's possible to track how long a visitor stays on your landing page and even send reminders based on that. Tools like Google Tag Manager can be set up to track the time a user spends on a page. You can trigger events when someone stays longer than a few seconds or minutes. With this, you'll know how engaged they are or if they're just bouncing off quickly. To send reminders, you'll need to collect their details first—like an email or push notification opt-in. Once you have that, you can use services like email automation tools or push notification platforms to follow up. For example, if someone spends 40 seconds on your landing page but doesn't convert, you can send a reminder later based on that action. This helps bring back lost traffic and possibly turn it into sales. Has anyone else tried something similar using other tools or methods?
