From now on, you have full control of your website indexing. You can allow or forbid search engines to crawl your website with just one click.

Find a magic switch that lets it happen at the bottom of the page in the General info tab in the Settings. 

After toggling on or off the “Visibility in search results” option, don't forget to publish your site for the changes to take effect.

Note that this switch is on by default, which means that your website is indexed in search engines after you publish it for the first time.
