Hi Tyler!
Oh man, you would think I'd be better at this. Actually I really suck at it. Here's what I mean.
Two years ago I submitted 5 talks. All of them were rejected but one, to CSS Conf in Boston. They took a chance on me. If you look at the analytics for my site, it was a flatline until that event. I had under 1000 followers then. That talk kicked things off for me and I started being invited to events.
The following year I submitted 5 talks again. All were rejected. But I was invited to speak at something like 25 conferences.
This year I submitted to two conferences. Both were rejected. But I was invited to speak at over 50. I think you get the drift.
I think I'm actually probably really bad at writing CFPs, but thankfully, I'm a much better speaker.
Marcy Sutton is really good at submitting though, and she did a writeup full of suggestions. She's an excellent speaker and is often selected so I'd take her advice over mine any day: marcysutton.com/writing-winning-talk-abstracts
