This is a tutorial sponsored by Zenfolio that I thought was worth repeating here.
Branding has two purposes: to differentiate yourself from others, and to communicate to your market who you are as a professional.
Display your logo on your social media pages and website. Consider setting the profile picture as your logo, so that it is recognizable and your brand will slowly start to catch on.
Keep your brand fresh and up to date. Over time, consider a redesign; the major themes and design choices of brand do not need to change but you can still update how you illustrate them. It's smart to update your website, blog and marketing every two to three years.
That being said, I'm freshening up my own brand to better fit what our business is about. It says to ask trusted friends to give you feedback... maybe I'll post it on fb!
I used to use this design on my letterhead and invoices. .... time for updating!
