I have reviewed and published several papers for conferences in Computer Science. You got good suggestions so far, I'd like to add one important thing:

* Choose and Know your community!

When you choose a venue like a conference, you are writing an article with the intent of being read by a very specific subset of the research community. You can imagine each subgroup having a set of "interesting conversations" around a narrow set of topics or methodology that are deemed important by the community.

So ... you have to convince your audience that you are contributing something to their conversation. Go look up papers in the previous edition of the conference, dig into their references, and frame your contribution in the term of the conversation they are having. In this way it'll be easier for everybody reading the paper to understand what you are doing.

In some cases, it might be that you are telling the community that they should care about this new problem of yours, but if it is completely unrelated to their discussion, it'll be an harder sell.

Also, be aware of the style of the community: are they interested in experiments backed by strong theoretical work? Or are they more interested in practical experiences, without caring much about theory? A decent paper accepted in a theoretical conference might actually be rejected by a more practical conference (and the other way around).
