How Do Web Push Notifications Work?

Web push notifications work by using a service worker, which is a script that runs in the contextual of a web browser. When a user visits a website that ropes web push notifications, the browser asks the user if they want to subscribe to receive notifications. If the user agrees, the browser generates a unique identifier for the user and registers this identifier with the web push service.

The web push service is a third-party service that handles the delivery of push notifications. When the website wants to send a push notification, it sends a message to the web push service. The web push service then delivers the message to the user's browser, which displays the notification to the user.

Web push announcements can be sent even when the user is not vigorously using the website. This makes them a powerful way to reach users and keep them engaged. Web push announcements can be used to send a variety of messages, such as:

New blog posts

Product updates

Sales and promotions

Event reminders

Account alerts

Other important information

Web push notifications can be a valuable tool for businesses of all sizes. They can help to upsurge website traffic, improve customer engagement, and boost sales.

Here are the steps involved in how web push notifications work:

The user visits a website that supports web push announcements.

The browser asks the user if they want to subscribe to receive notifications.

If the user agrees, the browser generates a unique identifier for the user and registers this identifier with the web push service.

The website sends a message to the web push service.

The web push service delivers the message to the user's browser.

The browser displays the announcement to the user.

The following are the key differences between push notifications and web notifications:

Push notifications are sent directly to the user's device, while web notifications are sent to the user's web browser.

Push notifications can be directed even when the user is not actively using the app, while web notifications can only be sent when the user is actively using the web browser.

Push notifications are more secure than web notifications, as they are not sent over the open internet.

How push notification works in Chrome?

Push notifications in Chrome work in a similar way to how they work in other browsers. However, there are a few key differences.

First, Chrome uses a different web push service called Google Cloud Messaging (GCM). GCM is a more secure and reliable service than some of the other web push services available.

Second, Chrome requires websites to use a service worker in order to send push notifications. A service worker is a script that runs in the contextual of a web browser and can be used to handle tasks such as caching resources and delivering push notifications.

Here are the steps involved in how push notifications work in Chrome:

The user visits a website that supports push notifications.

The website checks to see if the user has enabled push notifications. If not, the website asks the user to enable them.

If the user agrees, the website registers the user's browser with GCM.

The website can then send push announcements to the user's browser.

When the user receives a push notification, it is displayed in the notification bar of the Chrome browser.

The following are some of the things to keep in mind about push notifications in Chrome:

Users can choose to opt out of getting push notifications from any website.

Websites can only send push notifications to users who have opted in to receive them.

Push notifications can only be sent to operators who are using the Chrome browser.

How are push notifications triggered?

Push notifications can be triggered in a variety of ways, contingent on the platform and the app. Some common triggers include:

User action: Push notifications can be triggered by user actions, such as clicking a button, addition an item to their cart, or leaving a website.

Time: Push notifications can be triggered by time, such as sending a reminder to take medication or a daily weather forecast.

Location: Push notifications can be triggered by location, such as sending a notification when the user arrives at their destination or enters a specific area.

Event: Push notifications can be triggered by events, such as a new blog post being published or a sale starting.

Personalization: Push notifications can be personalized to the user, such as sending notifications about products they have shown an interest in or events they are attending.

The specific triggers that are available will vary depending on the platform and the app. It is important to choose triggers that are relevant to the user and that will be likely to get their attention.

Here are some additional considerations when triggering push notifications:

Frequency: It is important to be mindful of the incidence of push notifications. Sending too many notifications can be maddening and may cause users to unsubscribe.

Timing: The timing of push notifications is also important. Sending notifications at inconvenient times, such as late at night or during work hours, can also be annoying and may cause users to unsubscribe.

Content: The content of push notifications should be relevant and interesting to the user. It should also be clear and concise, so that users can quickly understand what the notification is about.

By carefully considering the triggers, frequency, timing, and content of push notifications, businesses can ensure that they are using this powerful tool effectively to reach and engage their users.
