@Cheese9Man Are you ADS or hip firing?
For me, I hip fire and strafe. But I'm more of a spam crouch than a strafer. It depends on the range as to what my movement is. If I'm sniping or in mid range I just rotate the movement thumb stick in a circle. It typically gives you enough movement to avoid shots but not so much you miss shots. It definitely takes some practice. Now better snipers or mid range players will have no issue hitting you. If you run into that try peak a shoot. basically peak sort of line up your sights where the target is.. hide then peak up again take a shot.. This one takes practice as well but when it starts to click you'll see what I mean.
In close combat I simply hip fire, it will take some trial and error to learn what range hip fire is effective at. I just recently changed how I do this all though. Sort of a combination of strafing, crouch spam and I toggle between hip fire ADS. If I'm reloading then I throw all kinds of movement into it, jump, slide, what ever to make them miss shots.. Some guns are not worth hip firing, Mastiff, Moz I will never hip fire. Those are guns you have to be accurate with and definitely more of a peak a boom weapon.
If you need to work on it a good starting point is the firing range with the dummies on. You'll still need practice in game because the dummies have 0 movement. but it will give you a starting point.
