There are a number of different metrics available to determine a sites authority or strength but in this instance we are referring to Ahrefs Domain Rating or DR.
Presently I am in a position to offer some highly effective link building that will see your sites DR increase to a minimum of 30 with a money back guarantee if this does not occur in a 30 day period.
As well as a DR30 rating its also very likely that certain keywords (taken from your site) will rise dramatically in the SERP's, citing a personal example where after employing this strategy for my own game at https://crimecity.cc its score went from DR0.07 at the beginning to currently DR39 and for the keyword CrimeCity, it went from page 8 in the Google SERP's to currently being on PAGE 1, ultimately meaning more traffic to your game/site.
The links are permanent and Google safe including Adsense, I use Adsense at CrimeCity and it does quite nicely.
The cost is $35 with keywords being taken from your website and if you'd like to explore this offer further, feel free to send me a PM.
