Website and Niche Name questions

Hi, I am hesitating with a name for the website that is describing what I will be doing or my I know that the only way to know what is right is to pick one and see. I wonder however if there is a general rule of thumb. It seems that the LCS podcast gives a lot of examples of website names that give away what the coaching is about rather than the names of the Coaches. Would love to hear your thoughts about this.
