AMP concentrates on improving page-loading presentation and browsing experience of a website on mobile devices. Thus, having plain page with only the crucial information without many fancy features compared to other HTML pages. It avoids data ten times from a usual website or app that isn’t so useful for a busy information seeker, to deliver the informative content in the fastest possible time.
Google quotes “AMP aims to improve the performance of the mobile web dramatically. We want web pages with rich content like video, animations, and graphics to work alongside smart ads, and to load instantaneously and wants this technology platform independent in any manner.”
AMP was especially designed for publishers, and publishers still make up a big chunk of AMP content out there. As of today, many industries are transitioning specific content on their websites into AMP pages because they offer such an improved user experience to the traditional slow-loading mobile web.
Features of AMP

AMP ADVANTAGES AND DISADVANTAGES

- Publishers of the website have full control over both the business and visual design.
- The pages that use valid AMP version will be shown as a preview of the ‘Top Stories”, above the other results in the mobile search results for the topic. This is a huge opportunity for publishers who have the AMP version of their content to be readily visible on the front page, and outrank those who haven’t adopted the technology.
- It is not suitable for Ecommerce website.

How Google Accelerated Mobile Page or AMP Works?

Step 3: AMP version directs to the non-AMP version with a canonical tag.
Difference between PWA and AMP
- While AMP reduces the page load time, PWA pages update as soon as possible to let users surf and experience a mobile-app-like-website, without any interruption.
- AMP gets content in front of users fast, while PWA enables rich user experienceand engagement through features like push notifications, add to home screen button etc.
- AMP is particularly suitable for static content heavy websites like blog, articles, news publishing or publisher-based website. PWA is best suited for e-commerce websites, as PWA enabled sites to look and feel like mobile apps. They are recommended for “https” sites that are secure connections between site and users.
THINKING about AMP and PWA
It is very significant to know the difference between AMP and PWA, but you need to understand each of their features, similarities and dissimilarities. If you’re an “HTTPS” website owner, then you need the support of both the technologies to serve your visitors better, thus you need to study Google AMP vs PWA.
With AMP, users get access to content quickly while PWA improves user experience and keeps them engaged. To explain in simpler terms, AMP is the waiter responsible for serving the food quickly while PWA is the cook preparing dishes that look appealing and taste delicious. Both the new facilities PWA and AMP are added for website development.
If you have an eCommerce website, you can never disregard PWA that gives your website the feel of a mobile app in mobile devices, letting users have a smooth mobile-friendly experience even without installing the mobile app. AMP can also be used for e-commerce sites, however, there are limitations which might be time and cost consuming to work around. Websites that are highly active and interactive benefits from PWA more, as they focus on improving engagement and experience and not merely on loading content fast. If you want your customers to come back often and interact with your site, PWA will be a wise choice. Also, with PWA increasing its features and offline capabilities to integrate NFC, Bluetooth, mobile phone sensors and other hardware functions, there is no reason why you should consider these.
Though, it is noticeable that Google is giving extra preference to AMP. currently, Google has come up with a new visual content “Snapchat-like Media Content”. This content format is based on AMP and is very much similar to stories feature of Snapchat. This new Google AMP initiative, named as “Stamp”, where ‘St’ stands for stories, is based on AMP for faster loading of pages.
AMP to PWA flow is a gradual process, websites first accept the AMP technology and then shift to PWA. Similarly, Washington Post article first came up in AMP carousel before registering in Service Worker. They started incorporating more navigation facilities in PWA for better user- experience with an aim to increasing users who accept this flow. So, they simplified the process by providing instant loading of pages on Washington Post domain. Once a user becomes a frequent visitor, they promptly show ‘add to home screen’ option. Once a user accepts it, it becomes a one tap experience.
Today, Google is paying attention towards turning the readers into paid traffic. Here the news publishers will not have to pay to advertisers for their news articles. From now on, Google will search for potential subscribers through AMP webpages, who are willing to pay for recent updates. No such initiatives have benefited Google while utilizing the PWA technology. Therefore, AMP is still the best option for Google.
INCORPORATING PWA and AMP
AMP and PWA work together pretty much good when combined. You can install a PWA app shell from your origin with the help of the amp-install-service worker. This enables users clicking on the designated button at the end of an AMP page to navigate easily to a total package PWA browser. Similarly, PWA can even accommodate AMP documents within it due to AMP’s portability feature. Understanding both of them is the key to proper implementation.
Now, if you are considering in hiring someone to work on AMP or PWA for your website, make sure that you are only hiring the top talent among the freelancers and agency.
