Hreflang: technical SEO for a bilingual Dubai website
A large share of Dubai businesses publish in both Arabic and English, and a fair number add Russian, Hindi or Chinese. That creates a technical problem specific to this market: several pages carrying the same meaning at different addresses, competing with each other unless you declare the relationship.
Hreflang annotations tell Google that these URLs are alternates of one another and which audience each serves. Get them right and an Arabic speaker in Dubai is shown the Arabic page. Get them wrong and the annotations are ignored wholesale.
The rule that is broken most often is reciprocity. If the English page names the Arabic page as its alternate, the Arabic page must name the English page back. A one directional declaration is discarded. Every page in a set must also list itself, and the set needs an x-default for anyone the other entries do not fit.
Two further points matter locally. Language and region are separate: ar is Arabic anywhere, ar-AE is Arabic for the United Arab Emirates, and using the wrong one narrows or widens your reach unintentionally. And hreflang is a targeting signal, not a ranking one. It influences which version is shown, never whether the set ranks. For bilingual businesses this is the highest value technical SEO fix available in Dubai, because it decides which language a searcher is shown.
