The current development of the Internet and its growing use makes it necessary to satisfy the needs of all users including those with disabilities having accessibility problems. Therefore we developed a new validator software called XValid, which is a human controlled testing tool for specific needs in light of design for all. We used the well-known WebXACT and this newly developed XValid validator for testing in 14 categories: Journals, Web Shops, Government Sites, TV channels', Educational, Commercial, News, Time-tables, Spare time, Museums, Assistive technologies, Chat sites and Sport news, Bank web pages. We made a comparison between both testing results. Based on these results we want to open web-designer's eyes to the typical errors.
