Requesting E-A-T Advice

Hi,

My name Lei Wi, I am currently creating a blog and looking for some advice in relation to ensuring that my content does not get penalised by the google.

So I have a author name, he is not real person, profile picture ai generated, etc. so he has no credentials nor exist in any realm of the world. I understand a key characteristic of google especially if writing content from a position of the experties is to have a profile that is credible.

I have a couple of questions in relation to this.

Is googles credibility checks done by a human or a robot? If anyone is know.

Would adding stuff like a twitter profile, real linkedin profile with the fabricated profile, phone number (even if not active) assist in improving the credibility of the posts by the author?

Thank for the input, really looking the advice to be seen as a high quality, and highly credible website. Currently not many articles and no backlinks so building up the articles before I look to do the backlink.

Will be looking forward to hearing from you all.

Kind regard

Lei Wi
