Web push notification structure

Let’s have a look at the main elements of web push on the example of notification received in Google Chrome browser.

• [1] - an icon of the browser. Marks the browser in which notification was received. 

• [2] - notification icon where you can place a small icon/image or your logo. 

• [3] - big image. It is not an obligatory element. In fact, the feature is supported only by Google Chrome, Microsoft Edge and Opera browsers. 

• [4] - close or disable notifications from a particular site

• [5] - web push notification title. The visible length depends on the browser and operating system. Supports emojis.

• [6] - web push notification body. As well as with the title the visible length depends on the browser and operating system. Supports emojis.

• [7] - link of the site that sent the notification. Note, if you have Basic Integration, the domain of PushPushGo will be visible in the link (see the screenshot below).

• [8] - Action button. This feature is supported by Google Chrome, Microsoft Edge and Opera. Also, Google Chrome supports two action buttons.

• [9] - notification settings. The user can manage his web push preferences from the notification itself as is shown on the screenshot.

Please, note there are no specific requirements from browsers regarding the lengths of the text in web push messages. We gave recommendations regarding the number of characters but there is a possibility that your message may be too long because some characters take more space than others, for example, “iii”  VS “mmm”. So, try to keep it short and remember brevity is the soul of wit :)

To sum up

Even though every device, operating system and browser affect the appearance of a web push notification, you can use the preview of notification in the PushPushGo application while preparing your campaign.

Moreover, in order to provide a better user experience, you can send the campaign to particular tags that have similar requirements to the web push notification, for example, you can choose a segment “desktop+Windows+Chrome+Edge+Opera” (as you, probably, noticed, notifications received in Chromium-based browsers (Google Chrome, Edge, Opera) do not differ significantly). In this way, you can be sure subscribers will receive notifications where all the text is visible along with a big image.

If you send the campaign to all subscribers, pay attention to which group prevails, for example, if it is Android/Google Chrome users, prepare the notification by orienting on this segment.
