Discover What It Takes to Build a Personal Brand for Less Than $15 Marketing strategist and speaker Dorie Clark leads an online class on building your personal presence and portfolio.

A solid personal brand is capable of moving mountains — or at least the stock market.

You might recall an incident that went down this time last year involving the personal brand of none other than Kylie Jenner. On February 21, 2018, the 21-year-old reality star and makeup mogul took to Twitter in response to Snapchat's confusing new layout, revealing that she'd begun to abstain from the messaging app.

"Sooo does anyone else not open Snapchat anymore? Or is it just me... ugh this is so sad," Jenner told her followers.

That single tweet from one of Snapchat's most prominent users — all 88 characters of it — was enough to cause Snap's market value to plummet about $1.3 billion.

Jenner's tweet had that incredible impact because she's used social media to build a personal brand that's garnered her millions of followers, who look to her for beauty tips and first-hand peeks at her lavish lifestyle. Her effect on Snap is an extreme example, but it demonstrates the extent of the influence one can wield with a fine-tuned and well-known public image.

The concept of honing a personal brand isn't reserved for celebrities, though. As consultant and author Peter Gasca once pointed out in an opinion piece for Entrepreneur, marketing oneself as a brand is a wise personal and professional move for, well, basically any businessperson in that it "[establishes] confidence, credibility, and courage."

"As an entrepreneur, a well-defined personal brand can also assist in establishing your leadership style and establish how you want to be known both in and out of the workplace," he wrote.

So that's the "why" of setting up a personal brand; now, for the "how": You can get a comprehensive introduction to all things personal branding by enrolling in "Personal Branding For Creative Professionals With Dorie Clark," an affordable online class about positioning yourself and your small business.
