HTML5 Notifications is simple: we make notifications in one line, like in GMail. How to disable browser push notifications Push notifications in php browser

Push notifications are pop-up messages that contain a short text, an image, and a link to the sender's website. Initially, they were used only in mobile applications, but in recent years, the technology of browser push notifications, or web push, has become popular.

For sites, such notifications are an effective way to build their own subscriber base. In order to become one of them, the user just needs to click on a button in a pop-up browser window. After that, web push messages pop up with sound and and on top of all windows on the computer screen, even when the browser is not running.

Who sends them and why users need it

Push notifications are actively used by news portals, online stores, travel agencies and even some banks. The media thus announce new articles, online stores - promotions, sales or assortment updates; travel agencies - current offers on hotels and tours, banks - mailing lists for their products. In addition, this way you can receive notifications about payment for goods, reminders about the extension of service tariffs, confirmation of information about departure / departure (in the case of travel agencies), and other notifications.

The main advantage of push notifications is that, unlike e-mail newsletters, such messages are more targeted. Each registered subscriber is assigned an encrypted string (token). The token is unique for each domain, key, and device type. Thanks to this, a user who subscribes to web push from a work PC will not receive additional notifications on their mobile phone or personal computer. Therefore, it is also impossible to take the base of tokens of other people's subscribers: each site will have its own token.

Why is everyone complaining about web push

The disadvantages of push notifications stem from their own advantages: not all companies use this method for its intended purpose, continuous text messages with the same type of advertising turn into spam. If a user has too many subscriptions to notifications from different sites, at some point it starts to get annoying.

How to turn off push notifications in your browser if you don't like them:

In Google Chrome:

Launch the Chrome browser on your computer, click on the three dots in the upper right corner of the window and go to "Settings";

At the bottom of the page, click "Additional";

In the "Privacy and Security" section, select "Content Settings";

Select "Notifications";

Choose the appropriate option:

1) block all notifications - disable the "Ask permission before sending" option.

2) block notifications from a specific site - next to the "Block" inscription, click "Add", enter the page address and select "Add" again;

In order to re-allow notifications from a specific site, next to the "Block" inscription, click "Add", enter the page address and select "Add" again.

In Safari:

You can hide requests from sites to send notifications in Safari by choosing Safari menu > Preferences > Websites > Notifications. In the last section, uncheck "Allow websites to ask permission to send push notifications". From now on, Safari won't ask you when you visit websites that can send notifications. You can also enable notifications again if necessary in the browser settings.

In "Yandex browser":

To create this browser, the same engine was used as in Chrome, so the algorithm of actions here will be almost the same. In order to turn off notifications, you need to go to "Settings", then open "Advanced", find the "Personal data" section in them and click on the "Content settings" button. In the "Notifications" section, after that, select "Do not show notifications from sites" and click "Finish".

Opera:

Click on the "Menu" icon with the Opera icon, go to "Settings" and select "Sites" in the list of sections. After that, in the left part of the window, find the “Notifications” item and check the “Forbid sites to show system notifications” item.

In Mozilla Firefox:

Firefox is an exception to all browsers: here you can also turn off notifications by checking the "Do not disturb" checkbox in the content settings, but they will only be blocked until you restart the browser. Users who want to disable push notifications once and for all should open a new tab in their browser and type about:config in the address bar.

After that, the browser will show a warning about the risk of changing the settings - you need to confirm that you accept it. Then type in the search bar dom.push.enabled. In the window that appears, switch the parameter value from true to false. This means that you can forget about push notifications.

In this short note, we will try to tell you about a new way to keep an audience thanks to Web Push technology and try to understand how it can be useful for website editors and other Internet services.

Push notifications are a way of conveying information to the user by sending short messages to the phone or browser, even when the user has left the site. Most likely, you have already met this method in mobile phones, when the application shows a message on the lock screen, whether it is an invitation to the game or notification of a new message in Whatsup.

All this has been working fine on phones for more than a year, but for the Web "a such an opportunity was not available, or rather, it was available to a very narrow audience.

But in April 2015, everything changed, because the Chrome developers added the Push technology to the Chrome browser and thereby reached more than 55% of the Internet audience for the desktop at once (statCounter data).

Firefox is following along, which only enabled push notifications in January 2016 and has a coverage of about 17%. Yandex.Browser, similarly to Chrome, supports this feature on desktops.

For Russia, the chart of coverage by top browsers is as follows and is more than 70% according to StatCounter:

This means that more than 70% of your site's audience may receive browser notifications.
What's more, Chrome on Android also supports this great feature, so your site visitors on Android mobile phones can receive notifications in the same way.

So how can this be useful?
Push notifications work even when the user has left the site.
This means that you can deliver messages about new content, new events, and other situations where you need to notify the user.

For example, several applications
RBC offers to subscribe about new materials through a modal window immediately upon entering the site

iphones.com

meduza

But there are many more applications:

customers of the online store can receive a notification about the status of the order;
when working with CRM - notify authorized persons about changes in the status of an order or a client;
weather sites - notify a person about the weather in the city;
integrate into the business process and do not forget about meetings, tasks;
Internet services - remind about payment to the client, notify about internal events;
for forum owners - subscription to new answers, comments.

In some way, Push notifications for the web can replace SMS and mail, and since the information is delivered immediately, the reaction is much faster.

According to push notifications company Panaur.com, the percentage of response to a subscription reaches 65%.
Users want try a new way, especially since there are no costs: 1 or 2 clicks and you don’t need to enter your mail, phone number, etc.

Real example
Internet service Publer, which cooperates with us, this week celebrated the first year of work and made a promotion for its customers about the sale of access. The percentage of responses (transitions) was 21% and push notifications helped to sell the entire promotion in a day.

Little statistic
According to our data, the percentage of notifications delivered immediately reaches 65-70% and gets about 10% more during the day.
Clicks on delivered - 20-25%

This means that if you have, for example, 50,000 subscribers, you can expect about 6,000 mailing list clicks.

Thus, push notifications are an old and, at the same time, a new way of interacting with the audience, which allows you to not only attract, but also retain visitors to your projects, which is user-friendly and beneficial for owners.

I propose not to waste time, but to implement this type of interaction in your projects as soon as possible, and we, the Panaur team, will be happy to help you with integration and technical assistance.

How to turn off push notifications - this question worries some users who see notifications in the browser after logging into many sites on the Internet. Push technology is designed to distribute information on the Internet from the provider, in this case, the site, to the user of this site.

Push notifications for the site are needed to inform website visitors about the news, mainly about the release of new articles. In this case, the visitor receives notifications from the site in a timely manner and can immediately read the news.

Notifications on behalf of the site are sent using a third-party service that organizes the delivery of notifications to users' computers.

What is a push notification on a computer? If a site visitor agrees to receive messages from this resource, then from time to time, notifications about the news of this website appear on the user's desktop.

How push notifications work

When visiting a site that has the function of sending notifications enabled, the visitor each time sees a request to allow the display of notifications, in which it is proposed to click on the "Allow" or "Block" buttons. The names of the buttons may be different, but the meaning is the same everywhere.

The site visitor can ignore this popup because the push notification request window is small and does not interfere with browsing the site.

The appearance of such windows is different, depending on the service that sends notifications from this site.

By clicking on the "Allow" button, you agree to receive push messages on your computer.

In the notification area, on the desktop of the user's computer, notifications about news on this website will appear. Usually, this is a message about the release of a new article. Some sites abuse the ability to send alerts, notifying about everything in a row, sometimes sending unnecessary information.

After receiving a push notification, the user can go to the site to read the article, or close the notification by ignoring this message. Such notifications from sites practically do not interfere with the work on the computer, since they are displayed in the notification area and close on their own after a short period of time.

To prevent the request for permission to send alerts from this site no longer appears when you visit this website again, click on the "Block" button.

If you are already receiving push messages from a particular site, then the user can disable push notifications on their own in their browser, in which they have allowed receiving notifications on their computer.

How to remove push notifications after receiving an alert

In many notifications, depending on the settings of the service that sends notifications, you can disable push notifications directly in the window of the opened message.

Article Conclusions

The user can independently disable push (push) notifications in the browser that he receives on the Desktop of his computer, allowing notifications to be sent from a specific website.

Surely everyone who used Google mail at least once saw notifications like this:

gmail notifications

These notifications are called HTML5 Notifications, and they are visible even if you switch to another tab or minimize the browser altogether.

After reading this article, you will be able to make the same notifications for your site. The code is simple, cross-platform, and directly sending a notification takes only 1 line in your favorite JavaScript.

Also at the end of the article there is a ready-made function with which you can start sending notifications without going into details.

According to caniuse.com , now such notifications (HTML5 Notifications) work in Chrome, Firefox (35+), Opera (27+), Safari (7.1+) browsers. Internet Explorer does not have Internet support for notifications. If we consider mobile platforms, then only Android Browser has partial support for HTML5 Notifications.

Before we can send notifications directly, we need to get permission to do so.
You can do this using the Notification.requestPermission() method:

Notification.requestPermission(function(permission)( // the permission variable contains the result of the request console.log("Permission request result:", permission); ));

After executing the method, the result of the permission request will be stored in the permission variable.

Here are its different meanings with explanations:

default - a request for obtaining rights was not sent;
granted - the user allowed to show notifications;
denied - the user denied showing notifications.

Having received the rights, we can proceed directly to sending notifications.
This is done very simply, in one line:

Var notification = new Notification(title, options);

title - notification title,

options (optional) has the following options:

body - notification body (main text), truncated differently in different browsers and operating systems (for example, in Chrome under Win 8.1, the maximum length is 200 characters);
dir - notification display direction, can be auto, ltr (left to right) or rtl (right to left);
lang - notification language;
tag - a unique notification identifier that can be used to replace it with another notification or delete it;
icon - URL of the image that will be shown in the notification (recommended 40×40 px resolution).

Let's try to set the parameters and send a notification:

Var notification = new Notification("How many TYU programmers does it take to screw in a light bulb?", ( body: "Only you!", dir: "auto", icon: "icon.jpg" ));

The result of executing the code above

Notification also has onclick , onshow , onerror , onclose event handler methods:

Function clickFunc() ( alert("The user clicked the notification"); ) notification.onclick = clickFunc;

Result:

On click

One function for everything

Now we will collect everything in a single function and add a few error checks:

Function sendNotification(title, options) ( // Check if the browser supports HTML5 Notifications if (!("Notification" in window)) ( alert("Your browser does not support HTML Notifications, it needs to be updated."); ) // Check , whether there are rights to send notifications else if (Notification.permission === "granted") ( // If there are rights, send a notification var notification = new Notification(title, options); function clickFunc() ( alert("User clicked to the notification"); ) notification.onclick = clickFunc; ) // If there are no rights, try to get them else if (Notification.permission !== "denied") ( Notification.requestPermission(function (permission) ( // If the rights are successful received, send a notification if (permission === "granted") ( var notification = new Notification(title, options); ) else ( alert("You have denied showing notifications"); // The user denied our request to show notifications ) ) ); ) else ( // The user previously denied our request to show notifications // At this point we can, but we won't bother him. Respect the decisions of your users. )

We now have a nice feature that makes it easy to send notifications without being distracted by rights requests or browser support:

SendNotification("Bring back Linus!", ( body: "Testing HTML5 Notifications", icon: "icon.jpg", dir: "auto" ));

The result of executing the function in different browsers:

When visiting new sites, a small window sometimes appears in the upper left corner of the browser, asking for permission to deliver certain notifications to you.

If the user approved receiving such notifications once, later in the task area of the computer or mobile device, he will periodically observe the appearance of small windows with a message that new publications have appeared on these sites.

These are the so-called push notifications, they are also web-push - a modern tool for Internet marketers. And the most convenient means of informing users who want to keep abreast of events of interest to them.

What are push notifications?

Push notifications are short pop-up notifications that appear on the screen of a regular computer or mobile phone and announce important events and updates.

When you click on a push notification that a user has received, site news immediately opens in the window, and users can be among the first to get acquainted with the information that has just been posted to the network. And sometimes it is important to be among the first users who have useful information.

Rice. 1. What Push Notifications Look Like

Site push notifications are enabled by site owners, and users can manage push notifications through their browser settings. If the webmaster has not enabled push on the site, then the user does not have the opportunity (or need) to use them, configure them, etc.

What are the advantages of push notifications compared to other methods of delivering fresh information? How to manage such a tool in the desktop browsers Google Chrome, Mozilla Firefox or similar? Let's consider these questions below.

Benefits of push notifications

The benefits of implementing push notifications on sites for their owners, that is, for webmasters, are obvious. The fact is that few means of informing can provide 90% message delivery to the user and almost 50% delivery.

But what benefit does the reader of this or that site receive?

Push notifications for some users may be more convenient than subscribing to site updates by E-mail. Messages coming from different sites do not accumulate in the mailbox and do not complicate access to personal correspondence.

If at the moment the user does not have time to read the news, then by clicking on the push notification, he can open the page in a browser window and leave it until a convenient moment. Or send it to a lazy reading service like Pocket or Readability.

One of the disadvantages of subscribing to site news by E-mail is the accumulation of letters about new articles in the user's mailbox. With a push notification, there will be no overflow in the mail.

With insufficient protection of the site from hacking, it may happen that the database of site subscribers falls into the hands of scammers who first organize this database (the so-called spam attack). Then every email owner from this database receives such fraudulent spam emails. It is believed that with push notifications in this regard, users are more securely protected: no one else, except the creators of the sites of interest, will be able to disturb users, no matter who hacks anything on such sites.

Push notifications and RSS feed

In terms of spam protection, web-push is similar to another means of delivering fresh information published on a particular site - an RSS feed. The latter even wins in that it keeps a history of messages about the publications of sites to which an RSS subscription is issued. Whereas pop-up notifications disappear forever after a few seconds.

But the use of RSS feeds for news delivery requires the user to perform independent actions: he needs to find the subscription button on each site (and it does not have a standard location) and enter the channel address into the RSS reader. If the user does not have such a reader in the browser, it still needs to be organized separately, for example, by installing an extension, selecting a web service, or resorting to using the appropriate program.

Push notifications themselves pop up and offer to subscribe, and their implementation is provided by the standard functionality of almost any modern browser.

Setting up push notifications in Google Chrome

The implementation of pop-up notifications in Google Chrome and browsers built on the same Blink engine (for example, ) offers the user a completely open subscription format that does not require him to make any choice.

A push request in Google Chrome contains two functional buttons:

"Allow" to approve message delivery (1 in Figure 2) and
"Block" to add the site to the list of blocked ones (2 in Fig. 2).

In the latter case, requests will no longer appear on subsequent visits to such a site.

There is a third option: clicking on the cross in the request window allows you to postpone the decision (3 in Fig. 3). The site will not be blocked, and after a while such a request in the upper left corner of the Chrome window will appear again.

Rice. 2. What a Push Notification Request Looks Like in Google Chrome

Setting up push notifications in Mozilla

In Mozilla Firefox (and other browsers based on the same Gecko engine), the web push delivery request form is more clever than in Google Chrome, or rather, with the inclination of the user to a specific choice.

The “Allow notifications” button (1 in Fig. 3) is accentuated by color indication,
and as an alternative, it is opposed to the delayed decision button “Not now” (2 in Fig. 3).

The "Never Allow" notification blocking button (4 in Figure 3) is smaller and hidden inside the "Not Now" button (3 in Figure 3).

Rice. 3. What a push notification request looks like in Mozille Firefox

Allowed and blocked push notifications are not synchronized with browser profiles. After installing a new operating system, when switching to another computer, and even after reinstalling the browser itself with cleaning up its remnants during uninstallation, you need to start all over again - respond to site requests again, form a base of permissions and blocking for push notifications from scratch.

Unsubscribing from web-push and blocking them

An excessive amount of pop-up messages can become annoying to the user over time. In addition, our interests may change.

How in such cases to unsubscribe from irrelevant sites or completely disable the delivery of push notifications by the browser? And how, on the contrary, to unblock sites that were mistakenly blocked when prompted?
