Progressive Web Apps vs. AMP
There are a few key differences between the two which are listed as under:
- Both technologies work simultaneously and help to reduce the waiting period and page loading times.
- While AMP helps to bring down page loading times, PWA pages update automatically in the shortest possible time span to proffer an enriching mobile app-like-website surfing experience to the users.
- AMP furnishes content quickly whereas PWA extends user engagement through a bunch of features such as add to the home button, push notifications, etc.
- AMP is predominantly suitable for static content websites such as blog sites, new publishing sites, etc. On the other hand, PWA is best suited for e-commerce websites, as it gives the look of a mobile app. They are highly recommended for 'https' websites which are protected connections between users and website.
So, do you necessarily have to choose one over the other?
The answer is 'No.' In fact, progressive web apps and AMP work great together. In many cases, they supplement each other and their collective use is becoming majorly prevalent among developers. By blending the two technologies together, you can reduce high page load time and long waiting durations. On a mobile site, even duration of three seconds seems to be long. According to a study, 53% of users refuse to wait on a website beyond three seconds and jump to the next URL or search.
Thus, to decrease this bounce rate, the two technologies can come to play.
Three ways of using AMP and PWA together:
1. AMP as a progressive web app
If your content is majorly static, then opting for this option is a great choice. It allows you to leverage AMP's lightning fast speed to proffer rich experiences as a PWA. For instance, what you build will be a PWA entirely AMP-charged. Per say it will have a service worker that will offer offline access and a manifest that will display the 'Add to home screen' banner.
2. AMP to a progressive web app
The most credible feature of AMP is the almost-instant delivery, which makes it an ideal fit for the user's first interaction with the site. Progressive web apps, on the other hand, offer more engagement through its wide array of features. However, its first load is stalled by the fact that site's Service Worker is only quickening delivery on subsequent loads. Therefore, it is an ideal strategy to make an AMP page as the entry point into the site, and following that, warm the PWA behind the scenes and reel the users into a progressive web application.
3. AMP in a progressive web app
One of the best features of AMP is that they can be easily and safely embedded within a specific area of a web page. This is helpful in decreasing the complexity of the backend and lowering its load time, without compromising on including dynamic functionality. To do this, you need to use another form of AMP, known as Shadow AMP, which allows the AMP to nest within a specific area of the web page.
Both the technologies come with their own set of benefits. While AMP offers quick access to the content, PWA improves user experience and keeps them engaged. If you are an 'https' website owner, you essentially need a seamless blend of both technologies to serve your visitors better.
