Business Definition of “PWAMP”
The acronym “PWAMP” stands for “Progressive Web App with Accelerated Mobile Pages”. The term PWAMP is used to describe progressive web apps that adhere to Google's AMP specifications for accelerated mobile pages. It is a combination of PWA and AMP, two commonly used acronyms.
What Does “PWAMP” Mean?
A PWAMP is a PWA (Progressive Web App) that adheres to the AMP framework, which is a limited set of HTML, CSS, and Javascript components maintained and approved by Google.
Usage example
Our online store is a PWAMP. We firmly believe that PWAMPs will have an advantage in search aquisition over the next few years.
The term PWAMP is mostly used by web developers and SEOs, two groups with a strong vested interest in developing the mobile web and reaching more users on mobile devices.
When to use a PWAMP vs a PWA or AMP site
PWAMPs can provide excellent performance because they combine the ultra-fast load times of AMP websites with the interactive functionality of a PWA.
PWAs should be considered for projects where users are expected to navigate many pages within the web site, and can benefit from app-like experiences such as offline viewing and fast page changes. (Think online store.)
AMPS should be considered for projects where the initial pageload time on mobile devices is important for retention, but advanced bespoke interactive functionality is not as important. (Think news publisher.)
PWAMPs should be considered for projects which require both of the above — online stores that rely heavily on mobile discoverability by users with shaky LTE connections, for example. While this use case sounds almost laughably niche, the use of PWAMPs by recognized companies like Flipkart.
PWAMPs: Examples in The Wild
Examples of PWAMP websites include: the phone case company Carved, the SEO marketing page WMWTD, and AMP’s own documentation site, AMP By Example.
What Is the Difference Between AMP and a PWA?
PWA is a term for a variety of methods for producing native-app-like experiences on the mobile web. AMP is an HTML framework developed open-source by Google that restricts developers from loading pages down with resource bloat. The difference is that AMP is a framework, while a PWA is an end product produced by using modern web technologies like Service Workers combined with UI effects like Splash Screens.
PWA stands for Progressive Web App, meaning a website that functions similarly to a native app: lightning-fast pageload times, content cached locally for offline viewing, push notifications, and advanced interactive functionality.
AMP stands for Amplified Mobile Pages, which is a framework for developing mobile pages that load quickly and feel “amplified.”
The difference is subtle, and it sometimes makes sense to use AMP when developing a PWA, resulting in a PWAMP.
What are some agencies that specialize in PWAMPs?
WompMobile is an example of an agency that specializes in building AMP and mobile-focused web apps, with a particular focus on PWAMPs. In fact, a presentation on PWAMPs they gave at the AMP Roadshow event in Los Angeles was where the author of this website first heard the term.
Origin of PWAMP
The term PWAMP is sometimes attributed to Webmaster Trends Analyst Gary Illyes at an SMX AMA event in 2017. However, mentions of the term PWAMP can be found in search engines going all the way back to 2016. The term was likely invented by the AMP team themselves.
How to pronounce PWAMP
While the acronym “PWA” is pronounced letter-by-letter in most cases, the longer acronym “PWAMP” is pronounced all in one sylable, exactly like it looks — resulting in a pronunciation similar to the sound of slapping a volleyball.
