Push ads can help you reach people on different devices because they work through browsers, not just websites or apps. If someone agrees to get push notifications on their phone, they might also get them on their laptop if they've subscribed from there too. This gives you the chance to remind them about an offer they saw earlier. Many push ad platforms allow you to target by device type, like desktop, mobile, or tablet. You can also choose certain operating systems or browsers. This helps you show the right message on the right device. Some platforms can even track user behavior across devices, so if someone visits your landing page on mobile but doesn't buy, you can show them a push ad later when they're on desktop. That kind of follow-up can make a big difference in sales. Has anyone tried cross-device targeting with push ads and seen good results?
