Any advice on how to get more speaking bookings

I speak at events and companies but with the amount of experience online here do any of you have advice on getting more gigs.

Hi Tony, could you tell us a bit more about your target audience and the content you offer?

Hi My main audience are HR professionals and training managers. This is the kind of event Im currently doing as a promotion and have a number of regular business customers but looking to find a wider audience I have held these in teh City of London before but this is my 1st one in a more localised sector
