.ae domains that contain hyphens or numbers are not worthy of investment.
Beware of misspelled words. The UAE follows the British spelling format, so “Theatre” and “Centre” are more appealing than “Theater” and “Center”.
Stay away from words that are usually not common in the UAE. “Physician” is really “Doctor”, and “Inn” is predominantly refered to as “Hotel” in the UAE.
Stay away from regulated activities, such as “Donation” domains.
With the exception of rare cases, do not invest in geo domains such as Keyword+UAE.ae, or Keyword+Dubai.ae.
Three-worded domains are not a good idea.
