I've found writing a book, blogging, and building a Facebook group to be the most effective way to build my brand.

Of course, everyone has different strengths, so it depends on what your strengths are.

I would read Traction by Gabriel Weinberg (the CEO of Duck Duck Go). It is about different methods for gaining traction with your startup. Some of them also are effective for building your personal brand, for example, PR, unconventional PR, social, SEO, content marketing, email marketing, viral marketing, engineering as marketing, tradeshows, offline events, speaking engagements, and community building.

Unconventional PR essentially means doing publicity stunts. Ryan Holiday wrote a great book about this called Trust Me I'm Lying.

Best of luck!

Be good at what you do and be humble. The best way to talk yourself up is to have others do it for you.

Create high quality content that other people will appreciate, and put it out in the world for free.

1. Create (anything), and share it with the world.

2. See what happens.

3. Reflect on any feedback you receive.

4. Adjust.

5. Do it again, over and over.

Probably speaking publicly, and/or writing (a book, or writing for a magazine or something).
