No you have not been penalized. Sander is correct you simply need to work on your SEO & branding. Effectively all you have done is a couple of backlinks and a link to yourself http://esta-compare.org/
There is so much out there to do - to get some domain authority. There are also many articles and links to same. I suggest you start with:-
https://moz.com/beginners-guide-to-seo/growing-popularity-and-links
The second one I attach is a favorite (non-link) - is a video which makes it a little easier and very well stated on what matters.

All the best.
