- Ideally, you don’t want to change your domain name. It’s not just about SEO, but also from a user experience point of view.
- Every domain builds up Authority and you’ll lose some when you move (leaky bucket syndrome).

- Non-dodgy reason: If you’re creating a new domain for other reasons, you’ll need to set up 301 redirects – this means they’ll automatically be redirected to your new web address.
