Welcome to the Q&A Forum

Based on different preferred domain URLs under site settings, we have added three Google webmaster accounts for our client's website as below:

Is it a good practice? or we should have only one with one "Don't set a preferred domain"? Can you please advise what is right?

1) example.co.uk

Site settings:

Preferred domain:Display URLs as example.co.uk

2) www.example.co.uk

Site settings:

Preferred domain:Display URLs as www.example.co.uk

3) https://www.example.co.uk

Site settings:

Preferred domain:Display URLs as https://www.example.co.uk
