Google is now your pre-interview. I interviewed someone this week. I google’d someone him. I learned a little about him:

Where he got his doctorate.
That the foundation he works for really exists and that the opportunities are real.
Where he used to work.
What he looks like.
That his online presence is consistent.

There are tons of ways and profiles that will allow you to claim you online presence. No one will represent you better than you. If someone wants to hire you, give you their business, or give you a donation, you want to be found. Let me know if you need help.
