Launching an Arabic or bilingual website? Check RTL layouts, typography, mixed-direction text, accessibility, Core Web Vitals, and multilingual SEO.
Creating a good Arabic website takes more than translating English labels. Teams must account for reading direction, navigation, icons, typography, forms, dates, mixed-language content, accessibility, and search visibility. A homepage may look correct while a checkout form quietly mishandles phone numbers and punctuation.
Use this practical checklist before releasing an Arabic or bilingual website.
1. Set the document language and direction
Arabic pages should declare lang="ar" and dir="rtl" on the root HTML element. English pages should use the corresponding English and left-to-right values. Direction is semantic: it changes how the browser handles text ordering and punctuation, not just visual alignment.
<html lang="ar" dir="rtl">
...
</html>
For content of unknown direction, such as user-generated text, dir="auto" can help. The <bdi> element isolates bidirectional fragments, such as a username inserted into Arabic interface text. These techniques prevent confusing punctuation and number placement.
2. Build layouts with logical CSS properties
Prefer padding-inline-start, margin-inline-end, and other logical properties over hardcoding left and right throughout the design. Check Flexbox and Grid ordering. Not every visual should flip: directional navigation arrows may need mirroring, but logos, media controls, and certain universal symbols should remain recognizable.
3. Validate Arabic typography at realistic sizes
Choose Arabic typefaces that are readable at body-text sizes, support needed weights, and have balanced line spacing. Noto Kufi Arabic is one option for a contemporary corporate interface. Limit unnecessary font files to reduce loading cost and test fallback behavior.
Check actual strings, not placeholder Latin text. Arabic phrases can occupy more or less space than their English counterparts; buttons, cards, and headings need flexible layouts.
4. Test mixed-direction content and localization
Email addresses, URLs, file names, reference numbers, currency symbols, and international phone numbers often appear inside Arabic paragraphs. Test them in tables, alerts, forms, receipts, and support conversations. Consider left-to-right input direction for known LTR values such as email addresses.
Dates and currencies require localization, not just alignment changes. Use established formatting tools such as JavaScript's Intl.DateTimeFormat and Intl.NumberFormat, and confirm what numbering style your intended audience expects.
5. Test mobile screens and accessibility
Inspect navigation, cards, filters, sidebars, modals, and long tables on narrow screens. Watch for overflow when users enlarge text or use device accessibility settings. Verify visible form labels, keyboard focus, sensible tab order, and adequate contrast.
The WCAG accessibility guidelines offer a useful standard for designing experiences that more people can navigate and understand.
6. Measure performance on real devices
Google's Core Web Vitals cover loading, responsiveness, and layout stability. Its published “good” thresholds are LCP of 2.5 seconds or less, INP of 200 milliseconds or less, and CLS of 0.1 or less, evaluated using appropriate real-user data.
Compress images, avoid excessive font weights, reserve image dimensions to prevent layout shifts, and test on slower networks. A visually impressive page that responds poorly on customers' phones is not a successful launch.
7. Implement bilingual SEO deliberately
Give each language its own accessible URL, such as /ar/... and /en/..., with genuinely localized content. Titles and meta descriptions should match real search intent in each language rather than use mechanical translations.
For equivalent language versions, use reciprocal hreflang annotations that include each page itself. Set appropriate canonical URLs and ensure crawlers can discover links and sitemaps. A language switcher should preferably take visitors to the corresponding article or service page, not discard their context by redirecting them to the homepage.
8. Verify forms and system messages
Submit every form with Arabic, Latin, and mixed-language content. Check country codes, phone number presentation, validation messages, success states, search boxes, sorting controls, and automated emails. Test both successful flows and intentional failures.
Final launch checklist
- Arabic and English pages declare correct
langanddirvalues. - Navigation and directional controls behave naturally in both languages.
- Typography remains readable on mobile and with increased text size.
- URLs, email addresses, phone numbers, and numbers display correctly.
- Forms and error messages work in both languages.
- Images and fonts are optimized; field performance is monitored.
-
hreflang, canonical links, and sitemaps represent real pages. - Contrast, keyboard access, focus, and labels have been tested.
- Release, backup, and rollback procedures are ready.
Frequently asked questions
Is CSS direction: rtl enough?
No. Use the semantic HTML dir attribute to establish document direction, then logical CSS properties to design the interface.
Should every icon be mirrored in Arabic?
No. Mirror meaningful directional cues when appropriate; do not indiscriminately flip branded or universally recognized visuals.
Can Arabic and English pages live on the same domain?
Yes. Separate localized paths and clear language relationships work well when implemented consistently.
Build Arabic support into the project, not the final week
RTL defects are easier to prevent when Arabic content is included in design prototypes and testing from the beginning. Explore Barnamix website development or contact our team to plan a multilingual launch.
