Hi

The puzzle rating on chess.com gives you an estimate of your puzzle solving strength… It Is usually higher than your real game rating…. The higher your rating get, it means that your puzzle solving skills are improving… But you should focus more on finding puzzles in real game 🙂

it gives a good indication if you can see différents motifs of tactics . By checking the personalize tab , you can review any past puzzle  by clicking the little reverse sign in the upper right . This  will help you understand what you missed and you can even select the theme and difficulty if you want to train a particular one . 
 

The higher you get , the better at spotting tactics  you will be but it s not an indication of your level of play at all . Tactics is the most important aspect of chess but without the rest , you will be limited . 
 

in chesscom , you will always get minimum of 5 pts if you solve it completely and a maximum of 15 if you execute it under a minimum time which vary with the complexity . In lichess you have no time at all and will either get or lose the points according to the difficulty of the puzzle compare to your rating and you can adjust the difficulty level . 

Usually the tactic rating in chesscom is very inflated compare to lichess which is weird as the playing rating in lichess especially under 2000 is the one which is inflated compare to chesscom .

The rating you get from doing puzzles on chess.com can be a useful indicator of your chess tactics ability, but it's important to understand its limitations:

Yes, it means something:

Tactics Focus: The puzzle section trains a specific chess skill: tactics. Solving puzzles helps you identify winning opportunities (checks, forks, pins, skewers etc.) on the chessboard. A higher rating indicates you're better at spotting these tactical opportunities.

Skill Improvement: As you solve more puzzles and your rating goes up, it suggests you're getting better at recognizing tactical patterns and calculating variations.

Limitations to Consider:

Not Overall Chess Skill: Chess involves other skills like positional understanding, strategic planning, and endgame technique. The puzzle rating doesn't reflect these aspects.

Focus on Speed: Chess.com puzzles often have time limits, which might not reflect your ability to solve them thoughtfully over longer periods.

Rating Fluctuations: Your rating might fluctuate depending on the difficulty of puzzles you encounter. Don't get discouraged by short-term drops.

I think this may help!

The puzzle rating doesn't mean a lot.  The higher the better of course, but puzzle ratings are on a different scale to chess ratings and tend to be much higher.  Also, there is no time limit for solving the puzzles, so people who spend more time tend to have higher puzzle ratings.
