The bio text — not counting your name and your URL — should ideally be around 30-35 words. (1 - 2 sentences)
The following example text is 31 words:
“Slade Roberson is an author, professional intuitive and host of the popular podcast Shift Your Spirits, where he talks about spirituality with fewer hearts and flowers than most new age blather.”
