If you are targeting a narrow segment (for example, Russian-speaking mothers in Dubai Marina), a creative will burn out fast, within a week. If the audience is broad (all Dubai residents over 25), one creative can run for a month because you are constantly showing it to new people.
This is the key indicator in your ad dashboard. Frequency shows how many times one person has seen your ad on average.
What actually determines how long a creative lasts:
(01) Audience size and homogeneity
(02) Impression Frequency
Up to 1.5 to 2: generally safe
Above 2 to 3: CTR and conversions begin to drop.
Above 3 to 4: you are irritating your audience.
(03) Creative type and fatigue rate
Static images burn out faster
Videos (especially 15 to 30 seconds with a live narrative) hold attention longer.
User-generated content (UGC) and native formats last longer because they do not feel like advertising.
