The SEO impact of changing your domain should be insignificant, if managed correctly.
When changing a website's domain, we perform what's known as a
Domain Migration
. When we cary out the
Domain Migration
, we automatically setup 301 redirects for all aliases on your previous domain to the respective alias on the new domain.
For example, '
original-domain.com/about
' would be redirected to '
new-domain.com/about
'.
This ensures that all internal and external links continue to arrive at the correct page on the new domain.
According to Google's John Mueller, the power of your links is no longer reduced by performing a 301 redirect. This means the domain migration should, in theory, not affect your SEO.
If your old domain is with a 3rd party provider, you must setup the 301 redirects yourself. Failure to do so may negatively affect your SEO, as Google will see your website as a brand new one.
