If my main domain has poor reputation, can I switch to a subdomain?

Partial isolation:

• Subdomains have some independence
• But may inherit some root domain signals
• Not complete escape

Better than new domain because:

• Maintains brand connection
• Does not look like domain hopping
• Easier to manage authentication

Approach:

• Set up new subdomain with clean practices
• Warm up the subdomain properly
• May perform better than damaged root domain

Long-term:

• If root domain recovers, subdomain benefits
• If subdomain builds strong reputation, may help root
• Better integrated solution than abandoning domain
• Opening a new division while rehabilitating the main company.
