My tip to improve your typing speed is to... practice, again.. Take these typing test sites, make sure both of your hands are placed correctly on the keyboard so you know which hand is supposed to press a certain hand, you dont want the left hand pressing the K button dont you

What really helped me improve my typing speed is... practice. It's been years since i've first typed on a keyboard. After that, i've been practicing and got a high speed of 90+ wpm most of the time lol
