To get your website approved we need to verify the ownership of your site. To do that you need to add a line of code in the <head> of your site.
If you are using WordPress simply download plugin called Headers & Footers or a similar and once installed, add verification to the Head field.

If you are using a different system and you don't have coding skills it is best to contact your webmaster.
