The verdict in three sentences
A bilingual English + Arabic site is not double the price of a monolingual one, but it demands an i18n architecture designed from the start and real Arabic RTL handling. For a Dubai exporter, budget USD 15,000 to 40,000 in 2026, with a 20 to 35 % premium for translation, RTL and multilingual SEO. Misconfigured hreflang is the number-one cause of cannibalisation between versions.
Cost of a bilingual LTR + RTL site in Dubai
Price depends on page count, translation volume and RTL depth (full interface or content only). 2026 order-of-magnitude estimate:
| Line item | Detail | Cost (USD) | Share of budget |
|---|---|---|---|
| i18n technical base | Routing, structure, hreflang | 6,000 - 13,000 | ~35 % |
| Design + RTL templates | LTR/RTL mirror, Arabic typography | 3,000 - 8,000 | ~20 % |
| EN/AR translation | Content + SEO, native review | 2,500 - 7,000 | ~18 % |
| Content integration | 2 languages, media, metadata | 2,500 - 6,000 | ~15 % |
| Multilingual SEO | hreflang, sitemaps, keywords | 1,500 - 5,000 | ~12 % |
The RTL premium comes from the full interface mirror: text direction, alignment, icons, margins and components must flip cleanly.
Multilingual and RTL pitfalls
These mistakes are expensive to fix after launch; better to anticipate them.
| Pitfall | Consequence | Best practice |
|---|---|---|
| Missing/wrong hreflang | Cannibalisation, wrong language in SERP | hreflang + x-default on each page |
| Partial RTL | Broken interface in Arabic | Logical CSS mirror (start/end) |
| Raw machine translation | Loss of B2B credibility | Native review + domain glossary |
| Non-localised URLs | Weak international SEO | /en /ar subdirectories |
| Heavy Arabic fonts | Degraded LCP | Font subsetting, font-display |
| Non-localised numbers/dates | User confusion | Locale-based formatting |
Subdirectories (/en, /ar) are recommended to concentrate SEO authority on a single domain.
Mini case study
Karim, export director at an FMCG SME in Dubai, targets the Gulf and Europe. He launches a bilingual EN/AR site at USD 30,000 over 3.5 months (including USD 8,000 RTL + translation premium). 6-month result: the Arabic version generates 55 % of regional quote requests, English 45 %. With an average export order of USD 9,000 and 16 new prospects/month, the site pays back in about 5 months thanks to opening the Arabic-speaking market.

FAQ
Does Arabic RTL really double the design budget?
No, but it adds 20 to 35 % on the design/integration line because each component must work mirrored. A logical CSS architecture (start/end properties) sharply reduces this premium.
One domain per language or subdirectories?
For an SME, subdirectories (/en, /ar) are preferable: they concentrate SEO authority and cost less to maintain than a domain per language.
Is machine translation enough for B2B?
No. Credible B2B content requires native review and a domain glossary. Machine translation can serve as a base but never as the published version as-is.
How do I avoid cannibalisation between versions?
With correct hreflang on each page (including x-default) and per-language sitemaps. It is the number-one source of SEO problems on multilingual sites.
Can I add a language later?
Yes, if the i18n architecture is clean from the start. Adding a third language then costs mainly translation and integration, not a rebuild.
