my site is a bit older then yours but mine still gets nearly 0 traffic from google, try to focus on other search engines like bing, yandex, duckduckgo ...
my site for example got ranked on yandex for a keyword and since i update this particular section i get more and more traffic and ranking
sure yandex is mainly russian, turkish and general asian traffic but still i get around 200 users a day and every 2-3 weeks i get around 50-100 more
i hope that google some time will recognize my site as well and i can start grow my traffic
bounce rate is 30% and ppl spend 4:30mins on my site in general so i guess that my site has quality
