Speed features in Apex®
Apex® includes three features that make pages load faster, especially on mobile.
Accelerated Mobile Pages (AMP): an open-source framework for lightweight mobile pages. It is optional for search visibility, so use it where it helps.
Progressive Web Apps (PWA): your site can be installed on a device and load quickly on repeat visits.
Page caching for logged-in and logged-out users: visitors get a ready-made copy of the page instead of waiting for it to be built.
Why speed matters
Google measures page experience with Core Web Vitals: loading speed, responsiveness and visual stability. Fast pages keep visitors on your site and are easier for crawlers to process.
Accessibility and languages
Apex® follows ADA-conscious accessibility standards and supports multiple languages for audiences worldwide.
Page speed matters because slow pages lose visitors before they see your content. Fast pages keep people on your site longer and are easier for search engine and AI crawlers to process, which supports both user experience and discoverability.
What speed features does Apex® include?
Apex® includes three features that help pages load faster, especially on mobile: Accelerated Mobile Pages (AMP), Progressive Web Apps (PWA) and page caching for logged-in and logged-out users. You can combine them depending on the type of page and audience.
What is AMP?
AMP, short for Accelerated Mobile Pages, is an open-source framework for building lightweight pages that load quickly on mobile devices. It strips pages down to efficient components so they render fast on slower connections.
Do I need AMP to rank in search?
No. AMP is optional for search visibility, so use it where it genuinely helps, such as content-heavy mobile pages. Google evaluates page experience through Core Web Vitals, and a well-built, fast standard page can perform just as well without AMP.
What is a Progressive Web App?
A Progressive Web App (PWA) is a website that behaves more like an installed app. Visitors can add it to their device, and it loads quickly on repeat visits because key resources are stored locally. In Apex®, PWA support helps returning visitors get a faster experience.
How does page caching make a site faster?
Page caching serves visitors a ready-made copy of a page instead of building it from scratch on every request. That cuts the time before content appears. Apex® supports caching for both logged-in and logged-out users, so speed gains apply to more of your audience.
What are Core Web Vitals?
Core Web Vitals are the metrics Google uses to measure page experience: loading speed, responsiveness and visual stability. They reflect how quickly the main content appears, how fast the page reacts to input and whether elements shift unexpectedly while loading.
Should I use AMP, PWA and caching together?
You can, because each solves a different part of the speed problem. Caching speeds up delivery for everyone, PWA support improves repeat visits, and AMP can help specific lightweight mobile pages. Start with caching, then add the others where your audience and content benefit.
How do faster pages help AI search visibility?
Faster pages are easier for crawlers to fetch and process, so new and updated content can be discovered more reliably. Speed alone does not earn AI citations, but combined with clear content and structured data it removes a technical barrier between your pages and the engines reading them.
Does Apex® support accessibility and multiple languages?
Yes. Apex® follows ADA-conscious accessibility standards and supports multiple languages for audiences worldwide. Accessible, multilingual pages reach more visitors and give search engines clearer signals about who each page is for.
