If you are like me and come from other various MOBAS then smite may be a bit of a change. I recommend take it slow and lean more into a passive playstyle as you try and pick up good habits from those around you. Let the game and it's community try to help through the learning process. I promise that once you catch on it's well worth it. If I had to give one great standalone tip is to focus on more than just fighting. Conquest in a game of strategy. It can be really easy to fall for the desire to constantly fight. But for newer players you might find yourself on the losing side of those battles more and more. I recommend looking for non confrontational ways to get a leg up on your opponent. Make a smooth rotate for the Queen Naga. Be on constant watch on when your buffs and jungle camps come up so you can try to fit them in between waves so you don't lose wave experience. There are so many ways to play this game besides fighting. Learn them so that when fight do happen you always have the leg up due to your extra experience, gold, and buffs.
