An effective advertising or marketing campaign should make it clear what kind of person your product or service is for (and not for).
And remember that the more specialized the sub-niche, the easiest it is to attract ideal customers. If your product or service is appropriate for more than one distinct sub-niche, run totally separate marketing and ad campaigns, and use a different name for each one. Just like when prospective clients saw our ads and felt, ‘This is for me’, your ads should evoke the same response in your prospective customers.
