Progressive Web App (PWA)

تطبيق الويب التقدمي

A website that behaves like a native mobile app: installable on the home screen, works offline via service workers, sends push notifications, and loads instantly on repeat visits. For Gulf service businesses — real-estate portals, clinics, procurement platforms — PWAs eliminate the app-store barrier while retaining 90 % of native-app functionality at a fraction of the cost.

Dark Mode & Web ThemingSupporting both light and dark colour schemes via CSS custom properties and the prefers-color-scheme media query. Gulf users increasingly expect dark mode, particularly on mobile during evening hours. For Arabic bilingual sites, dark mode must be tested against Arabic typography—some Arabic typefaces have poor legibility on dark backgrounds. Theming architecture also enables Ramadan or national-day seasonal colour variants without rebuilding the design system.
Web Font SubsettingReducing a web font file to include only the glyphs (characters) actually used on a given page. Arabic fonts present a unique subsetting challenge because the Arabic script requires positional variants (initial, medial, final, isolated) for every letter, making raw font files significantly larger than Latin equivalents. A full Arabic variable font can be 300–600 KB; a properly subsetted version serving only the used characters drops to 40–80 KB, dramatically improving LCP and reducing data usage for Gulf mobile users on metered connections.
Mobile-First DesignDesigning and building websites starting from mobile experience first, then scaling up to tablet and desktop. Critical since Google indexes mobile versions first and Gulf users browse primarily on smartphones.
Answer Engine Optimization (AEO)Structuring content so that AI-powered answer engines — Google AI Overviews, ChatGPT Search, Perplexity, and Bing Copilot — pull your page as the cited source. Requires concise, direct answers in the opening paragraph, FAQ schema, and authoritative backlinks. Distinct from GEO: AEO focuses on being the cited source, GEO focuses on content completeness.
