Using personal website when applying for a job?

Hi.

 

Inn the sponsor spots for squarespace. most of the tech related youtubers, keep telling us that haveing a website when applying for a job is good. I am wondering what I should and should not have on such a website? 

I am cureently a intern. with 6 months left. Then I have to start searching for a job in networking. 

 

I apologize for structure in my post and the spelling may be wrong. I'm not good WHEN IT COMES TO ENGLISH WRITING.

I would assume it either needs to be a blog of experience with a bio page or basically a CV dressed up over a website.
