Search Engine Land has a blog that features the 10 most overlooked steps when changing a domain: http://searchengineland.com/changing-domain-names-2016-10-easily-overlooked-steps-can-save-seo-248484 I would definitely check that out. But here is the TL;DR version: Contact your hosting provider FIRST Verify all versions of the new domain in Google Search Console (GSC) Change the setting for WordPress address (and site address) Mod_rewrite or ISAPI_Rewrite changes Back up your site BEFORE you pull the trigger Edit backup plugin settings after the domain name change Submit a change of address in Google Search Console (GSC) and Bing Webmaster Tools (BWT) Change all internal links Edit Google Analytics settings and add annotation(s) Apply advanced settings in Google Search Console (GSC) Reconnect Google Search Console (GSC) and Google Analytics (GA) Also, don't forget that domain age plays a role in your domain authority and rankings!
