Targeting the wrong keyword can leave you battling giants; targeting the right one can lead to search engine success. So, depending on your current ranking, it may be best to avoid hotly contested keywords and go for those that are ripe for the taking.

The Keyword Difficulty Check tool will guide you on your way. Just type in a keyword or phrase, and it lets you know how easy or difficult it would be to rank for that term. Get high rankings for less-common keywords, or at least know what you're getting into with more popular words.
