Focus is to always create high quality, useful content that will please visitors. But your title needs to be compelling and it needs to read well and it should make sense to the reader.
By now we all know the benefit of including a researched keyword phrase in your Title. However, you can also improve your clickthrough ratio with 1 or 2 other elements in the Title too. I say use these, sometimes because you may only want to do this when it makes sense, but it does work if you do it well.
