mate your site is really cool, but it has a poor Domain Authority
sad truth is that sites with poor Domain Authority won't rank high in Google and in result get very little of traffic
I had the same problem in the past and my website didn't rank high in Google
I searched for a professional who would help me with it; found one guy who really helped me rank higher in Google and increase my Domain Authority to 58! I'm super happy with this score
