What are Web-Push messages?

Web-push notifications are content messages that you receive through a smartphone, website or web app. In order to receive push messages, you must allow notifications or subscribe to a specific website in Chrome, Firefox, Safari or another browser. Best of all, to receive them you will not necessarily have to be on the website where you subscribed.

When to use them?

Push messages work best when you want to attract users with limited time content. Also if you want to redirect users who leave the cart, activate offers on inactive users and retain readers with personalized content.


What are push web notifications used for?

Like notifications in mobile applications, push messages aim to facilitate the delivery of information to users. The only difference is that you will not have to download and install an application and just click on the “Allow” button to subscribe to notifications.

A lot of developers are using push web notifications to create brand engagement and retain more users. Companies in all categories also rely more and more on web-push as a communication channel.

On the other hand, SMEs rely heavily on push messages to constantly generate traffic to their website or online store.

The main reason for the popularity of web push notifications is the increase in the use of mass emails, SMS and ads as a marketing strategy.

  • Sales alerts, new coupons and product updates.
  • Sports results and news directly on the devices.
  • Informative messages about traffic, weather and general aspects.

  • In Windows, they are displayed above the taskbar.
  • In Linux, they are seen in the upper right section of the browser.
  • On Android, you can see them in the notification tray.
  • Apple must be configured to receive notifications.

You just have to keep in mind that the user must be an active subscriber in order to receive these notifications.

How do they work?

Attract traffic to your website, generate more sales and any other objective. You can send news, offers, new products, information about events, educational content, among others.

How to build a web-push notification?

There are 4 important elements that you should take into account when creating a push web notification: title, description, landing page URL, icon and Image and call to action buttons.

TIP: banner images and calls to action are only available for Chrome.

  • Title
    Your push messages should have an attractive title for users.
  • Website Domain
    This will be the domain of the website that sent the notification.

  • Call to action buttons
    You can add up to 2 CTA buttons in a notification (Chrome only) These buttons can be used for users to perform different actions such as: direct them to a landing page, allow the sending of a social message (Tweet), activating the Play Store or the Dialer to make a call.
  • Icon
    It is possible to add an icon to your notification. Placing your brand logo will be an excellent way to create greater brand remembrance and let your users know when it is a message from your company. The icon must be 100 x 100 px and must be less than 20 KB in size.

Steps to send a push message

Define the content: You can set the content you want to send using an interface or API. In this case we recommend using www.onesignal.com. While there are other options too.

When to send them: You must define whether to send the notification immediately, schedule them or leave them ready for the Api to handle it.

To who: It is important that you establish the audience to which you will send your notification, choosing between specific subscribers, segments or all.

Web Push notifications can be targeted and customized to select segments of your user base and even customized for specific users. In comparison to email or SMS, users are not required to share their personal information. The buying and browsing behavior of a user can be used to create powerful audience segments.
