Progressive Web App (PWA): The future of the web that works like an app

Have you ever? Go to the website and meet pop up. "Load our app!" ... and you immediately press off.

For business owners or marketing teams This picture is probably a familiar nightmare. We invested good websites. But enough to invite customers to bind each other more through "Application" He immediately turned away. The question is why? Because users of this era "lazy" download new apps that take a mobile area, have to wait for installation, and also have to keep updating They want to have a "fast" experience and "easy" like an app but still "convenient" to access like a general website. And if we say that ... it really has technology that can do that? Technology that combines the advantages of the web and apps together until the customers "almost do not know" that they are using the website. That is called Progressive Web App (PWA) and this is the future that will change the digital marketing game forever.

Real problems in life: "Wall" that is invisible between "websites" and "apps"

In the digital business world We always encounter a headache. During the creation of a "website" that can easily reach many people with the creation of "Native App" (apps installed from the App Store/Play Store) that provides better experience and creates a more profound bond. This problem creates a "wall" that is invisible.

User side (users):

• "The mobile area is full!": Everyone doesn't want to download the new app if not really necessary. To delete the image to install the business app that you just met for the first time? Forget it.
• "The internet is slow, can't load": waiting to download dozens of MB apps via 4G at a soft signal. It's a frustrating experience.
• "Going to the website is enough?": Most users feel that accessing the website is "easier" and "faster" for only time. Forcing the app to download is like creating a burden for them.

Business side (Business):

• "Cost of Brutal Development": Creating a separate application for iOS and Android requires a lot of funds and time.
• "Warning for installation": To make some customers press "Install", your app is very difficult. Requires a lot of marketing budgets
• "The website is not 'sticky' enough": Original website Lack of important qualifications in "Pull the customer back", such as sending the Push notification, when customers turn off the browser The relationship often ends there. Understanding Mobile-First Indexing Principle It is very important because it is the beginning of creating a good experience on mobile.
  Promt for creating images: The cartoon paintings show a large brick wall between the "users" who are playing mobile phones with "business owners" who are trying to submit an application across that wall. But the user shook his head. Why did that problem: when the world of "web" and "apps" are separated from the root cause of this problem, resulting in different evolution of the technology on both sides in the past? "Website" was created with the goal so that "anyone" from "anywhere" can access the information through the browser. It is a representative of "reaching" and "ease" but on the other hand "Application" was created to draw the "hardware" efficiency. It works quickly, accessing the features of the machine (such as cameras, GPS, notification) and work, even without internet. It is an agent of "Experience) and" engagement ". We want both! Traditional websites cannot send Push notification or offline work. While the app cannot be found on Google or shared with friends with a simple link. This is the "gap" in the technology that creates marketing problems that we encounter today.
  Promt for creating images: Simple infographic images showing the two -way intersection, one way, saying "Website (High Reach, Low Engagement)" points to the browser icon. Another way to say "Native App (Low Reach, High Engagement" points to the middle app icon. There is a big question mark. If left, how will it affect the cost of the competitors "faster" and "smarter" to ignore this gap and still adhere to the same way? May have more negative effects on the business than expected in the long run.
  • Loss of customers for competitors: If the competitor's website is faster, providing experiences like apps, and can send promotions via Push notification directly to the customers ... is not surprising that customers will choose them.
  • Conversion rate falls down: every second that the customer has to wait for the website to load Or every step that is complicated to use on mobile Is the opportunity for you to lose sales forever
  • Unexpected marketing costs: Investment in order to obtain "Download app" is many times more expensive than pulling people into the "website". If we make the website give a good experience as the app We will reduce this part of the enormous cost.
  • Missing the opportunity to communicate repeatedly: No Push notification means that you don't have a way to "whisper". Tell new promotions. Or important news for customers who have entered your website directly
  • Disadvantage in the era Mobile-First: Google is very important to mobile experiences. Slow and difficult websites on mobile phones will be reduced continuously. Causing customers to not find you The development of modern websites must therefore take into account the technology such as Webasembly that helps to increase the web efficiency to the next level.
