How do I increase my reputation score?

Hey guys, it's me again! I was just wondering why my reputation score haven't improved one bit since I became active again. I created an account here back in May then underwent a quiescent period of 5 months when I left and didn't write anything. I came back and started writing daily (even have my own daily series). I saw people who increased their score dramatically in a day while I was stuck at 42 eversince I came back. I red articles on how to increase it but they all just basically say continue posting, and I do, but it doesn't seem like it does anything for me. Now, I just want to ask for tried and tested ways on how to improve my score. Thanks a lot and have a great day!
