Able to be advertised or suitable for advertising; worthy of or capable of being promoted publicly.
From 'advertise' (to announce publicly) + '-able' suffix. The '-able' suffix means 'capable of being' or 'suitable for,' making 'advertisable' describe products or ideas that can effectively be marketed to the public.
Not everything is equally 'advertisable'—some products have regulations against advertising (certain medications, alcohol in some countries), which is why the word exists: to describe what society permits marketers to publicly promote.
