Moving your WordPress site to a new domain can be as exhausting as moving homes. it’s natural to get anxious that all the hard work we put into our SEO campaigns is going to go to waste. Our rankings will plummet, and we’ll lose visibility.
Here is the way to keep your SEO when you move into a shiny new WordPress domain.
Create a Complete Backup
Commence Migration
Set Up Permanent 301 Redirects
Update Your Incoming Links
Tell Google About Your New Address
