Alright Macro, lets define it first. Macro is the way in which you handle your money. Everything from keeping your production up to expanding at the right time has everything to do with macro.
Lets start off with production. The optimal situation for macro is this, that you are receiving enough income to keep production in all your buildings constantly queued at one and have no excess of money. For instance, a terran can comfortably pump off of 2 tech lab and 1 reactor rax per mining, fully saturated base. Furthermore they can pump off of a second reactor rax but you will be staggering production.
The key is to always have one unit producing without having to queue up additional units. Basically if you've got 3 marines queued into a barracks you are wasting 100 minerals you could be spending elsewhere.
Another important thing to do is to keep making SCV's, you want to keep making SCV's so that when you expand you can saturate quickly, thus allowing you to throw out more production.
When on the attack continue to produce, this is very important. In higher stress situations many players let their macro slip, the outcome of a game greatly depends on if you can continue to produce when attacking and being attacked. Many games are lost due to this fact alone.
Another important issue is when to expand. If you're newer to the game and don't feel comfortable expanding keep this in mind. When your opponent expands is a good time for you to do the same. If you're doing a gas intensive build and your minerals are beginning to pile up, it's a good time to expand. When you're making an attack or you when a battle it is a good time to expand. When you have map control it is a good time to expand.
All these are opportune times to expand, as you play longer you will get the flow of the game and learn when to expand and when not to. Eventually you will become comfortable and do it without thinking about it.
The final key to macro is supply. Even the best get supply blocked, but the more you minimize this the better your chances of winning are. This to, has an important effect on a game. Sometimes if it just slips your mind, supply drop is very powerful. Just remember to just keep tabs on this and minimize your supply blocking and you'll come-out ahead more often then not.
