If your newly created WordPress site is not indexed by search engines, then this is the first thing that you should do.
Login to your WordPress site and go to Settings » Reading page. Scroll down to the bottom of the page and make sure that the box next to ‘Search Engine Visibility’ is unchecked.
This option allows you to discourage search engines from showing your website in search. It is used by webmasters when they are working on a website that is not ready to be live. Sometimes you can accidentally check this setting and forget about it.
Make sure that this option is unchecked when your website is ready to go live.
