Google’s Keyword Planner is a free tool that anyone can use to find out what people are searching for in google. Simply type in any word or phrase, and it will show how many monthly searches that term gets, plus the same for a bunch of other related terms. It is invaluable if you are writing content that you want others to see, because incorporating the right types of keywords in there will result in your content getting ranked more highly in google, and possibly find its way onto page one for certain keyword phrases.

When you search this term in google, a few lines down you find The Online Ad Network (Toan) website. There’s a bunch of ads shown immediately, and guess who’s posting those ads? Ordinary people like you!
