The "anchor" is a combination of points to which the bowstring and/or the index finger of the drawing hand are drawn to on the face and neck. There are multiple ways of "Anchoring" the string after you have drawn the bow. Here are two of the most common ones.
The Side Draw: Hunter or Field Style - Pull the string back so the index finger of your string hand touches the corner of your mouth. This places the arrow directly beneath the eye that you are aiming with. This is recommended for all beginners. As archers continue to progress and put an aiming device on their bow they can progress to the next one.
The Center Draw: Target or Olympic Style - Pull the string hand under your jaw so the string is in the middle and in front of the chin. The string should also touch the nose. The string hand is in line with and directly under the jaw bone.
Remember that anchoring in the same place and the same way every time is critical no matter how you choose to anchor.
