It was removed by cPanel because all search engines submittal is a scam. The search engines want to be as organic as possible and people submitting their sites is not organic. All search engines now have bots that will find your site automatically but of course not all websites are accepted or included. To increase the amount of bots that find your site, get other sites to link to your site.
To get better exposure you will need to use a professional service to submit your website such Dot Easy Australia, for more details please check our website or contact the support team.
