I cant seem to improve even though I barely blunder and make a mistake once in a while.

Improving Your Chess - Resources for Beginners and Beyond

If you're losing against people at your level, that means that you make many mistakes, and blunders (they are about equal). In your last lost game (against MindlessDirt) you did 6 mistakes. You have diamond membership, so you can analyze that game in your own, I don't have to tell you your mistakes.

Your last decisive mistake in that game was trading rooks, after this trade your king was far away from the pawns, and your opponent successfully won the game, as their king was closer to the pawns

If you’re 800ish rating you’re obviously blundering a lot, because that’s pretty much the main characteristic of a player of that rating, you don’t get 800s who are solid and constantly getting ground down or whatever. 

I don’t say that to be unkind, but better to not have an unrealistic impression of where things are at leading to you focusing on the wrong things. So usual things, focus on board vision, blunder checking before you move, etc, doing puzzles but taking more care over them and so on

Sorry for saying about what I said about me not making mistakes/blunders, I didn't reveiw my games very well or didn't and also I think the reason I'm playing bad moves is because I like watching YouTube while I play chess.

"It is possible to commit no mistakes and still lose. That is not a weakness. That is life."

Sometimes people just play better than you do. Pay attention to what mistakes you make and make sure not to do those things.

Even if you don't blunder, small mistakes will add up, especially if your opponent doesn't mess up in return. An inaccuracy typically results in the game going at least -1 in your opponent's favor, so if you play enough you'll work up quite the advantage, even without a blunder.

Playing slightly bad moves that snowball into a losing disadvantage, as well as your opponent just being better than you, are things that people tend to overlook.

Try regular trainings with controling your progress.

Hey there.

I am rated over 2400 online (https://www.chess.com/member/ppandachess). I created a free course that will teach you a training plan to improve. Feel free to check it out: https://www.panda-chess.com/daily-improvement-plan

I'd also like to note: Sometimes a blunder gets only a ? or even a ?! because you were already getting steamrolled. Chances are, you are blundering and the game just doesn't tell you.

In my most recent game (as of this writing), my opponent played two blunders: One that hung a knight and bishop, and another that hung a rook and allowed a mate in two. Neither of them got the "??" symbol, though, because it was already not looking good for them. If the position were more balanced in either situation, they would have definitely received a "??".

Dear R0tt3n,

I am a certified, full-time chess coach, so I hope I can help you. Everybody is different, so that's why there isn't only one general way to learn. First of all, you have to discover your biggest weaknesses in the game and start working on them. The most effective way for that is analyzing your own games. Of course, if you are a beginner, you can't do it efficiently because you don't know too much about the game yet. There is a built-in engine on chess.com which can show you if a move is good or bad but the only problem is that it can't explain to you the plans, ideas behind the moves, so you won't know why it is so good or bad.

In my opinion, chess has 4 main territories (openings, strategies, tactics/combinations and endgames). If you want to improve efficiently, you should improve all of these skills almost at the same time. That's what my training program is based on. My students really like it because the lessons are not boring (because we talk about more than one areas within one lesson) and they feel the improvement on the longer run. Of course, there are always ups and downs but this is completely normal in everyone's career.

I hope this is helpful for you. Good luck with your games!
