Many speakers on broad consumer topics such as cancer awareness, phobias etc. Speakers with more general topic such as nutrition and health who have historically tried to get bookings in the association and corporate markets need to follow suit. Speakers will increase leverage by working with more audiences who are already sold on the topic but need specific help, rather than audiences who need to be convinced. Narrowing the marketing approach to target demographics leaves the positioning broad enough to make significant revenue but also focused enough to differentiate. Intersect these answers with association websites to get creative about where to speak and who to create with.
Media outlets are another great source for reaching a specific demographic group.
More profit can be generated when applying differentiated content to specific objectives in a leveraged way. Since 1987, Vickie K. Sullivan, President of Sullivan Speaker Services, has generated six-figure revenue streams for hundreds of experts and industry leaders who use public speaking as a marketing tool.
