Is it just me, or isnt it obvious that you should transfer your domains over to Google Domains. Google wants their search engine to stay the top dog. Now they are selling domain names. Isn't it a no brainer that they will give their domains preference in the serps or at least show you the most accurate picture and the best tools to help with how SEO and marketing should be handled. They do care about your site after all. They give you Google Analyitcs, Google Webmaster Tools, Google Adwords, Google Adsense, G Suite, Google Data Studio, etc... to help you succeed. Shouldn't having a domain with them improve your chances? Please let me hear your thoughts...
