Aim boards provide the feedback you need. Here are examples that work well with a putting alignment laser or with target holes.
The Aim Board
The triangular aim boards from Visio have 3 sides. Each side represents a specific distance of either 5,10 or 15ft. On each side there are markings that represent what various degrees of error would look like from that known distance. ★★★★
For example the 5ft side of the board shows marking for what 0.5, 1, 1.5 and 2 degrees of error would look like when putting from 5ft from the hole. (Note: From the photo above 2 or more degrees is a miss at 5 ft.)
The board can fold up flat to allow for easy transporting and can be locked in place on the green with tee pegs through holes located either side of the board.
This board has vertical lines on it that represent degrees open or closed at impact. Which is handy with a laser pointing at the board.
You can use it behind a target hole to measure your putter face angle at impact on straight putts. In other words, the ball would roll over the target hole and roll up to the aim board at a specific point.

The Target Backboard
The target backboard from Wright Putting Dynamics offers a great visual background for target reference indoors or outdoors. ★★★★
Target Boards
These work great as multiple targets for aim point putting laser practice or as a back drop for target holes.
I use a laser attached to my spare putter. The idea is to measure your aim at set up at 3 different locations.
I start out with all 3 in a semi circle at 5 ft. Then move them back to 10 ft. and then 15 ft.
A good place to start
Just because you start out square doesn’t mean you return the putter face to square at impact.
To measure the face angle at impact I use Blast Motion Golf.
Measuring setup squareness and face angle at impact are great. Aim is just as important and pace may be the most important.
You still need to get the ball to the hole to make the putt.
Aim Boards and long putts
On putts of 30 feet or longer I like to put something behind the hole. I have a tendency to leave those putts short.
So for example on a long putts, I put an aim point 10 percent beyond the hole. In other words, on a 50 footer, I put something 5 feet past the hole.
If you want to tighten things up a bit, use a 3 foot radius circle as a target on putts over 30 feet.
