I have been playing the game since it's been released and its probably one of the best mobile games i have ever played.When i first started i was rather poor but I think i have picked up well and getting some wins off late. So I thought I'd share some of these tips that worked for me over the weeks.
Before i start if u upvote the post it'll be highly appreciated, Thanks.

Practice in Solo arcade

Fighting alone in arcade will help you learn from your mistake and train you to make better decisions in future gunfights.Arcade modes are short and makes for quick bursts of game play, which makes them perfect for practice.

Positioning

When the playzone is small, try to go where the white and blue circles are the closest to each other. This should avoid many enemies sneaking up on you and should give you a good idea where everybody is. Its also worth noting that towards the end of the game trying to positioning yourself behind a rock or tree is always preferable. Being in cover puts you over a huge advantage over people who aren’t.

Looting

Looting in pubg is fun and stealing the gun your friend need is an absolute joy but focusing on looting after the 2nd circle is not a smart move as, the majority of the people have enough tools to kill other players so chances are you'll die more often during this part of the match while trying to loot.

RUNNING

When running out in the open always run in a zig zag motion. Make quick unexpected turns.This makes it harder for snipers to hit you.

Landing

Land in famous places like Pochinki, School, Georgopol etc,when landing on vacant places you're missing out of valuable gunfight experience .Also,try to always land around the same spot,this way after 5 to 6 matches you'll start recognizing a "path" for looting and you'll loot faster and more effectively.

Kill em All

When reviving an ally,shoot the enemies first this way you dont have to worry about dying when reviving.
Also when you knock an enemy down you can leave him as bait for his team and when they arrive you can finish the job.
