Note the fact that the strongest brands always have an equally large base of fans and detractors. The same applies to personal brands. Your goal is not to please everyone, but to take a stand and do not change it even if some people disagree.
Reject changes
We hear everywhere that we must embrace change and learn new things. Your personal brand should, however, be consistent and show the same values on a long-term basis. This does certainly not mean stagnation. If your brand is e.g. about creativity, be creative in everything you do.
Be promiscuous
Unlike personal relationships, promiscuity is highly desirable in online relationships. Build your contacts on social networks so that they do not involve only people from your industry or specialization. You need to get into wider networks where you will find more opportunities.
