Website speed and digital accessibility are pillars of effective eCommerce. In a world where every second of loading time affects conversion, and legal regulations increasingly require meeting accessibility standards (WCAG), traditional frontend solutions may no longer be sufficient.

Hyva is the answer to these challenges - a lightweight, modern theme for Magento 2, designed with performance, Core Web Vitals compliance, and easy adaptation to WCAG 2.2 requirements in mind. It's no wonder that over 5,000 online stores have already decided to use this solution.

Online store speed has a direct impact on customers' purchasing decisions. As shown in the Adyen Index: Retail Report 2025, as many as 39% of Polish consumers abandon their purchase if the order completion process takes too long. Moreover, 41% of respondents declare that they complete transactions in less than 5 minutes, and 14% even under 2 minutes (Gazeta MSP). This shows how significant the speed of the entire frontend is - from page loading to interface response time.

Data from Deloitte's "Milliseconds make Millions" study showed that conversion rates increased on average by 8% for retail sites and 10% for travel sites with page load time improvements of just 0.1 seconds. Importantly, faster-performing sites not only facilitated transaction completion but also increased user engagement. Retail consumers spent nearly 10% more, while for lead generation services and luxury brand sites, page views increased by 7% and 8% respectively (Deloitte Digital).

From an eCommerce perspective, this means the necessity of eliminating every unnecessary delay - both at the infrastructure level and the store code itself. The more efficient the platform, the greater the chance of retaining the user and converting them at the checkout stage. Speed today ceases to be an advantage and becomes a condition for basic functioning in the digital competitive environment.

Core Web Vitals is a set of metrics introduced by Google that measure the quality of user experience on a website. The tool focuses both on loading speed and evaluates websites in terms of real comfort of using the service, e.g., how quickly content loads, whether the interface responds without delays, and whether elements on the page move unpredictably during loading.

This set consists of three key parameters:

• LCP (Largest Contentful Paint) - the rendering time of the largest element in the visible area of the page.
• FID (First Input Delay) - the delay between user interaction and system response.
• CLS (Cumulative Layout Shift) - the visual stability of the page during loading.

CWV is an official ranking factor in Google, which means that their optimization affects not only UX but also visibility in search results. Combined with data that clearly shows the relationship between page speed and conversion, CWV becomes an important reference point for anyone thinking about effective and scalable eCommerce.

For online stores struggling with poor CWV results, the key challenge becomes choosing a solution that will actually improve performance. In this context, the decision to change the frontend ceases to be a matter of aesthetics and can become a strategic decision affecting conversion, SEO, and compliance with Google requirements and legal regulations.

CWV is also gaining increasing importance for language models (LLM) such as ChatGPT, Perplexity, or AI Overview. LLM considers the technical quality of websites, including loading time and accessibility, as one of the elements when assessing credibility and selecting content for citation. This is an additional argument to take care of performance at the frontend structure level to increase the visibility of your content in searches.

The Hyva theme, created for Magento 2, was born as an alternative to heavy, outdated frontend solutions. Based on modern technologies (including Tailwind CSS and Alpine.js) and simple HTML code structure, it stands out with minimal resource load. Thanks to this, pages built on Hyva load faster, achieve higher Core Web Vitals scores, and are easier to adapt to WCAG standards.

What's also important, Hyva not only improves technical parameters but also shortens implementation time and simplifies further store development. More and more technology companies already offer plugins compatible with Hyva, enabling quick and seamless integrations - an example could be the Przelewy24 payment solution. This type of compatibility makes Hyva gain popularity among companies that focus on quality, performance, and long-term scalability.

Another important aspect when designing and developing an online store is digital accessibility, defined among others by WCAG (Web Content Accessibility Guidelines). This is a set of international standards developed by W3C, aimed at ensuring equal access to web content - regardless of user limitations, such as visual, hearing, mobility, or cognitive perception disabilities.

The current version is WCAG 2.2, which extends previous guidelines, including requirements for mobile devices, simpler navigation, and cognitive limitations.

This standard is divided into three levels:

• Level A (minimal) - basic level of accessibility, required to meet the most obvious barriers.
• Level AA (standard) - recommended for most websites, ensuring a high degree of accessibility.
• Level AAA (extended) - the most demanding level, difficult to achieve for all types of content.

From an eCommerce perspective, accessibility is no longer just an ethical choice or expression of inclusiveness - it has become a legal requirement. The European Accessibility Act, which has already begun to apply in the European Union, imposes the obligation to ensure digital accessibility on online stores, mobile applications, payment platforms, and other commercial services. Failure to meet these requirements can result not only in loss of customers but also financial and reputational liability.

Hyva simplifies the Magento 2 frontend, which directly translates to easier implementation of digital accessibility principles. Thanks to clean, semantic HTML structure, abandoning JavaScript libraries, and greater code control, it's much easier to ensure proper headings, alternative descriptions, content readability, and keyboard navigation.

Additionally, using Tailwind CSS allows for quick adjustment of contrast, element sizes, and focus visibility that comply with WCAG 2.2 guidelines, including for mobile devices. However, it's important to remember that Hyva doesn't automatically ensure EAA compliance but significantly facilitates its achievement through its simplicity and flexibility.

Performance and accessibility rarely go hand in hand - many solutions focus on one of these areas while neglecting the other. Hyva breaks this pattern, enabling simultaneous fulfillment of technical requirements set by Google (Core Web Vitals) and legal regulations related to accessibility (WCAG 2.2). For store owners, this means fewer compromises, less optimization costs, and a consistent technological base that supports business development in the long term.

A well-optimized frontend not only speeds up page loading and increases conversion but also makes it easier for people with disabilities to navigate the site - especially those who use screen readers, keyboard navigation, or other assistive technologies. In practice, this means that the benefits of implementing Hyva are felt by every user, regardless of their technical or physical situation.

Hyva is not only better technical results but also a solid foundation for creating modern, aesthetic interfaces based on modern UI/UX standards. Thanks to the component approach, designers have complete freedom in creating responsive, intuitive, and visually consistent layouts. Importantly - design is not limited by heavy structures imposed by traditional templates. On the contrary, it becomes flexible, lightweight, and easy to personalize according to brand needs.

Additionally, thanks to Tailwind CSS, you can quickly prototype and implement consistent visual components that work smoothly on all devices and meet users' growing expectations regarding frontend quality.

One of the most recognizable examples of a Hyva store is the European Citizen brand store, which after implementing Hyva gained not only a modern, minimalist design but also a significant increase in key indicators. Compared year-over-year, the store recorded:

Metric	Growth
New users	+65%
Page views	+74%
Conversion rates	+43%
Revenue	+141%
Number of transactions	+161%

High Lighthouse scores (including Performance and Accessibility exceeding 90/100) confirm that Hyva enables simultaneous achievement of WCAG 2.2 compliance, Core Web Vitals optimization, and maintaining an attractive, modern store appearance (Hyva - Citizen's case).

Hyva is no longer a niche alternative for Magento 2. More and more brands and eCommerce agencies treat this solution as a real tool for building fast, accessible, and scalable stores.

This thesis is confirmed not only by the growing number of implementations but also by broad support from external integrators. The market sees fully Hyva-compatible plugins from providers such as Amasty, Mirasvit, Mageplaza modules, payment gateways, marketing automation systems, GA4 and GTM, which shows that this technology finds real recognition in the Magento ecosystem.
