Arabic-first or English-first for a Gulf business website?

This is usually argued as a cultural question. It is a commercial one. The right answer follows from who actually sends you money.

When should English lead?

• Most of your customers are expatriate residents, which is the majority of the population in the UAE.
• You sell to international clients as well as local ones.
• Your industry runs in English day to day — hospitality, logistics, technology, most professional services in Dubai.
• Your team writes in English and would maintain an English site more accurately.

When should Arabic lead?

• You sell to Arabic-speaking nationals, particularly outside the largest cities.
• You work with government entities or bid for public contracts.
• You are in Saudi Arabia, where Arabic leads far more often than it does in the UAE.
• Your competitors are all English-first and being the readable one in Arabic is an actual advantage.

Is one language enough?

Often, yes, and one good language beats two mediocre ones. A single well-written English site outperforms an English site with a machine-translated Arabic version stapled to it, because the second one loses credibility with exactly the readers it was meant to attract.

If you cannot get the Arabic written by somebody who writes Arabic, do not publish Arabic. That is a genuine recommendation, not a hedge.

What does "leading" in a language actually mean?

Three concrete things. Which version a visitor lands on by default. Which version gets written first, so the other is a considered version rather than a translation. And which version gets the design attention — a right-to-left layout that was designed left-to-right and mirrored always looks like it.

It does not mean hiding the other language. Both should be complete, both should be reachable in one tap, and the switch should keep the reader on the page they were already reading.

What goes wrong technically?

1. Machine-translated Arabic. It reads as machine-translated within a sentence or two, and on a site selling quality that is fatal.
2. A Latin typeface with an Arabic fallback. Arabic needs a face designed for it, usually at a slightly larger size and with more line spacing than the Latin at the same optical weight.
3. A layout that was not built for right-to-left. Icons that should mirror do not, numbers end up in the wrong place, and forms read backwards.
4. Numerals. In UAE commercial contexts Western digits (1234) are standard for prices, dates and phone numbers. Arabic-Indic digits are correct in some contexts but not in most commercial ones.
5. Missing hreflang tags, so search engines cannot tell which version to show to which reader.

Does two languages help you get found?

Yes, in the sense that Arabic search terms are less contested than their English equivalents in the same market. A well-written Arabic page can rank where the English one is fighting far more competition.

It only works if the Arabic pages are written rather than generated. A translated page competes against pages written by people, and it loses.

Questions people actually ask

Does a second language double the cost?

Not double, but it is a real addition. The writing is the slow part; the layout work is smaller if right-to-left was planned from the start and much larger if it was retrofitted.

Should the site detect the visitor’s language automatically?

Detect once, on the first visit, from the browser’s language setting, then let the reader override it and remember the choice. Detection that cannot be overridden is worse than no detection.

Which Arabic should the site be written in?

Plain, direct Modern Standard Arabic in the register a business owner actually reads in commercial contexts. Not the formal literary register, and not local dialect, which does not travel across the Gulf.
