While you are following this checklist, you don’t want Google and other search engines attempting to index your brand new website and finding it in a state of flux.
Go to Settings/Reading/Search Engine Visibility and check “Discourage search engines from indexing this site.” They may or may not observe this setting, but to ensure that they do, make sure you following through with the next task and set up a Coming Soon page.
Also, don’t forget to uncheck the “Discourage search engines from indexing this site setting,” when your site is ready to launch.
