I am looking for advice on how to get into conference speaking - specifically on "soft tech" subjects. Eg communication for developers and motivation/productivity style topics.

I have previously spoken at meetups, spoken in front of hundreds in big multi national companies and presented at European trade shows - now I'm looking to advance that into conference speaking.

I follow "call to speakers" on Twitter and this week have submitted my first two proposals I've read the excellent advice at speaking.io I've created a lanyrd speaker profile with details on Updated all relevant profiles of mine with details that I want to speak Spoken to conference organisers and speakers for help

What else could I be doing to increase my opportunities or chance of being accepted to speak?

Thanks
