Don’t be too modest or too limited in expressing your skills. Show what you’re capable off; show off your experiences, your blogs, your websites, your portfolio, etc. But, be crystal clear about what you are offering. Please try to avoid vague titles or skills.
As a freelancer, it’s really important to stay relevant, keep your skills up-to-date and continue to expand them. Use the time in between jobs for (online) courses. Or, provide coaching or mentoring to others, and add it to your profile. Be passionate about your skills and the entrepreneurship of freelancing.
