Letter W9 terms in the glossary

An international organization dedicated to standardizing internet technologies - it publishes the recommendations for HTML, CSS, WCAG, and other foundations of web development.

Thanks to shared standards, sites work similarly across different browsers and are easier to make accessible to all users.

A set of guidelines ensuring the accessibility of web content for all users, including people with disabilities - covering, among other things, color contrast, readability, and keyboard operability.

In Poland, the WCAG 2.1 AA requirement for the public sector (government offices, institutions) has applied since 2019 under the Digital Accessibility Act, transposing EU directive 2016/2102. Since June 28, 2025, an additional requirement - under the European Accessibility Act (EAA) - also applies to part of the private sector, mainly companies providing certain digital services (e.g. e-commerce, banking, transport). Not every company falls under this second regime - the scope is worth checking individually.

A service collecting site addresses by category. In the years when link count alone mattered, a directory listing was sometimes part of an SEO strategy.

Today directories are a neutral or outright negative signal for search engines - mass listings fit the pattern the Penguin algorithm targeted. That budget is better spent on a single link from a site someone actually reads.

Training or a presentation conducted over the internet, allowing participation from anywhere in the world without leaving home.

A popular way to gain knowledge thanks to easy accessibility - it requires no travel, and a recording often remains available after the event ends.

A status granted to companies specializing in handling and optimizing accounting and HR processes on the wFirma platform.

In practice, this means support in implementing and configuring accounting, invoicing, and HR tools, with access to the provider's priority technical support.

A method of optimizing a site focused on improving its quality and content, in line with search engine guidelines.

Unlike black hat SEO, it produces results more slowly, but lasting ones - without the risk of a penalty for violating Google's rules.

Areas of a design free of content, text, or graphics - despite the name, they don't have to be literally white; what matters is the absence of active elements in that spot.

Used well, it improves readability (separating and grouping content), aesthetics (a less visually cluttered design), and functionality (easier navigation, attention focused on key elements).

A simplified, schematic model of a page or app, showing the layout and structure of interface elements without visual detail.

Used at an early stage of design to establish content placement and user flow before the more costly graphic design stage begins.

The most popular content management system (CMS), built on PHP and MySQL, free and open source, allowing sites to be created and edited without writing code.

A huge library of themes and plugins extends its functionality - from a blog and portfolio to an online store or news site.
