Improving Your Chess - Resources for Beginners and Beyond…

Everyone will have their opinions and advice, and most of it will be good. Personally, I suggest the following.

1) play slow games. You need time to spot things, like which of your pieces are being threatened, which of your opponent's pieces are hanging, and so forth. As you play more, you will get better at seeing the board as a whole rather than as a collection of individual pieces, but that will take time and experience.
2) don't worry too much about memorizing openings, but rather learn opening principles (lots of resources available on this). Eventually you will gravitate towards learning some openings, but remember your opponent will probably go "off book" pretty quickly so don't bother memorizing lines beyond that horizon. As you improve, the horizon will move out but by that time you'll have the first set of moves under your belt. Also, when learning an opening, don't think of it as "for White" or "for Black", but try to learn both sides as you will probably end up playing the other side from time to time.
3) learn the simple checkmates (K+Q, K+R) and learn how to use your King to get a pawn to promotion (and how to prevent it when possible).

4) find a resource on basic checkmate patterns (things like "dovetail mate" and so forth), and don't forget to try to spot them in your games!
5) practice basic tactics (pins, forks, etc) and remember to look for when your pieces might be vulnerable to them
6) learn a few positional ideas - these are generally the "improving moves", where your best option doesn't involve an immediate tactic (might be things like getting your pawns on the opposite colour of your loan Bishop; or finding a good outpost square for your Knight; or bringing your rooks to control an open file; or limiting the options of one of your opponent's pieces to remove it from play, at least for awhile.
Each of those has a lot of stuff to learn, so don't try and learn it all at once. Pick something to work on specifically, and focus on that. As you become more comfortable (quicker) at that particular skill, then start to work on another. Remember, you can't learn everything at once, so don't confuse yourself by trying to. As you improve, you'll start to work out where your weaknesses are, and that will help guide you to deciding on what is next to work on.
Most of all, don't fret over your "rating". It will go up and down a lot, and often, it will go down as you start to focus on something new. It takes time to integrate new skills and to properly calibrate your calculations. Just have fun and enjoy the game.
I don't particularly enjoy playing people online as the virtual connection creates a real barrier for me in terms of enjoyment, so I only play the bots here. I far prefer playing people in real life OTB. If you have some friends who also play chess, I recommend you play on a real board, and writing them down for later analysis. But, again, that's just my personal preference and it may, or may not, apply to you. 
Anyway, the short version is two ponits. Play slow, and just focus on learning one new skill/idea which you practice in your games until you feel you've "got it" well enough that you are ready to learn another skill.

for everyone who says dont learn opening, this is all bunch of bullcrap, you absolutely have to learn openings and ideas behind them as to what to expect from the game that follows, you cannot just make random moves in the opennig and then expect to beat your opponent using superior tactics or what not, opening gives you position for the rest of the game, it is absolutely necessary to learn it and ideas behind them, as for tactics, you cannot just "learn" tactics, there are certain positionsa nd ideas behind them aswell, it is not like there are books on "tactics", those books on tactics are just games played by other players and common patterns that occur and you want to achieve in your games, chess is all about patterns, you are not going to be sitting there and outthinking your opponent, this happens very rarely, most of times you get a position you are familiar with and your opponent is not, so you know which way to go and that wins you games, at least this is the case at low levels, no idea what is going on in high levels of chess, but probably something same, except players know more patterns

Dude, when people say "no need to learn openings", they certainly don't mean "make random moves in the opening". Have you ever heard of opening principles?

The second part of your comment is equally nonsensical. All low rated games are won and lost by tactics. Yes, you can call it "outthinking your opponent".

Many people recommend to not learn openings, but I will say you, that if you know some basic openings, you can save some time in the game, and if your opponent doesn't memorize openings, he might get into trouble, or simply have less time than you have from the very beginning of the game

The lower rated players are, the less they know about chess, and the more likely that the memorization will go wrong. Memorizing opening moves without understanding the concepts is a sure recipe for disaster.

All chess players have only a limited time to spend on chess. For a low rated player, there are a dozen things that are more useful to learn than openings.

What's the best way to improve. I'm new.... :)
