The conversation is in Arabic, so the ad should be too
ChatGPT ads are matched to what the person is asking about, and targeting includes language and geography. In Saudi Arabia most everyday questions are typed in Arabic, often in dialect, sometimes mixed with English brand names. A Sponsored placement written in English under an Arabic conversation reads like an interruption. One written in the same register reads like a helpful next step. That difference is the whole game in a text-first format with no image to lean on.
There is a second reason. English-only campaigns silently shrink your audience to the part of Saudi Arabia that thinks in English at the keyboard, which is real but small next to the rest. In a market this size, that is money left on the table. We saw the same pattern for years on Google and Meta; the Arabic vs English ads question is old, and ChatGPT just makes the answer sharper.
Saudi dialect or MSA in ad copy
Ad copy should sound like a Saudi talking, not a textbook. Modern Standard Arabic has its place in a university prospectus or a government tender; in a short Sponsored line it sounds cold. Saudi readers respond to their own words: وش تبغى, ابشر, على طول. Najdi and Hijazi shading differ, and the Eastern Province has its own flavour, so the copy for a Jeddah restaurant and a Riyadh developer should not be identical.
The rule we use: dialect for the hook and the call to action, cleaner Arabic for anything factual such as prices, terms and credentials, and Latin script for brand names like ChatGPT, Mada and WhatsApp. Never translate an English draft; write the Arabic first and let the English follow. Then read it aloud. If it sounds like a Gulf marketer explaining something to a friend, it is right.
When English still matters
English still matters in three places. Riyadh's professional class, who read and write English at work and often ask ChatGPT business questions in it. Expats across the three cities, whose home language may be neither Arabic nor English but who use English as the bridge. And technical or B2B topics where the vocabulary itself is English: software, logistics, finance. For those, run English variants on the same topics and let the tracked results decide the split.
The mistake is to make English the default and Arabic the afterthought because the agency is more comfortable in English. Start Arabic-first, add English where the audience shows up, and never mix the two inside one ad in a way that reads as half-translated. Bilingual is a strategy; a half-Arabic, half-English soup is a bug, and Saudi readers spot it in a second.
Language parity: landing page and WhatsApp reply
The ad is only the first sentence of a conversation. If someone asks ChatGPT in Arabic, clicks a Saudi-Arabic Sponsored line, and lands on an English page with an English form, most of them leave. The landing page must be Arabic by default, right-to-left done properly, with prices in SAR and Mada, Apple Pay and BNPL visible at checkout. The English version is a toggle, not the front door.
The same applies to WhatsApp. A reader who wrote in Arabic expects a reply in Arabic, quickly, from someone who sounds local. If the first reply is a stiff English template, the paid click is wasted at the last step. We set up WhatsApp Business API flows with Arabic-first greetings and dialect-aware quick replies, and we tag the source so the conversion is attributed back to the ChatGPT campaign.
How Aahfil writes Saudi copy from Kuwait
Aahfil is based in Kuwait, and we are asked how a Kuwaiti team writes Saudi copy. The answer is: natively, by Gulf Arabic speakers who know the difference between a Kuwaiti and a Saudi phrasing, and by checking the copy with Saudi readers before it goes live. Gulf dialects are close cousins, and the gap between them is far smaller than the gap between any of them and MSA or Egyptian Arabic, but we still respect it.
