Congrats indeed.
It looks like Google just cleared a bit of a backlog. I had two posts indexed overnight. One I submitted about two weeks ago and the other a few days ago.
Now that they have found one post, if you keep posting and keep paying attention to on-page SEO and off-page SEO then Google will continue finding and indexing your posts!
Good luck and keep going!
Best regards
Andy

Very good on earning your Google badge Khemrin

Cool

That's really awesome. Congratulations!

As now your site is indexed by Google, you can start writing quality rich content if not doing so already.
