Much like with your Campaign and Broadcast messages, you want to make sure you're sending notifications at a rate that website subscribers are expecting. You also want to make sure the content in you notifications is relevant to your subscribers. These expectations can be set in the opt-in modal, where you can display a logo image and provide a brief description encouraging visitors to opt-in.
Although you're getting permission through the opt-in modal, you don't want to abuse that permission by pushing excessive notifications. Sending too many notifications, or too few notifications, could ultimately impact engagement with and conversions on your site. You also need to consider when you're sending notifications, but this will vary depending on what kind of content you're pushing. For example, if you want to send a cart abandonment notification, you might send that out an hour after they've left the checkout, but if you're promoting a new blog post, you might send that out immediately after posting.
AWeber provides click stats on your Web Push Notifications, so you can compare and contrast them to determine what is most successful for your subscribers. Much like your newsletter messages, you'll find that your website subscribers might interact with notifications more on certain days of the week or times of the day. Using your stats, you can adjust your sending practices to best fit your audience.
How should the notification look?
You can add a title, description, and image to your Web Push Notification. Web Push Notifications are relatively small, so you want to make sure the title and description are concise. Depending on what you're promoting, you can include a call-to-action. For example, if you want to encourage website subscribers to read your new blog post, you could write something like "click here to visit my blog."
The image should be a JPG, PNG, of GIF file type and less than 1.5 MB in size. The recommended size for your images is 192 px by 192 px or larger.
