If it hits 3-4" to the left, there are things you can do to bring it on target. If it hits more than that to the left, then it may be a type of bow you aren't used to. For example, whenever I shoot a Hill style longbow, it hits 6" or more to the left at 20 yards, because the shelf is not cut in as far as the other bows I normally shoot. I know that if I shot one long enough, my brain would make the adjustment and it would begin to hit on target, but I would prefer to continue to shoot the bows I already like that are cut past center.
There are some form things that can make that happen too. If you torque the string or the bow, it will throw arrows inconsistently to the left. If your dominant eye is not over the arrow, you can get a consistent left miss. If you're not coming all the way around to full draw so your elbow is behind the arrow, you can get a consistent left miss if you consistently short-draw to the same place.
To make minor corrections in the POI, try either a stiffer or weaker arrow, as either one may or may not move the POI to the right, so you may have to try both. Try a softer strike plate, like Velcro instead of leather, or a rug rest instead of Velcro. If your strike plate is thicker than it needs to be, try a thinner one.
