Keyword

A keyword is a word or phrase you tell Google you want to show up for, so when someone searches something close to it, your ad can enter the auction.

Someone types emergency plumber bangkok into Google, and you want to be there at that exact moment. A keyword is how you raise your hand for that search. You add keywords to an ad group, and each one is a bet that the people searching that term are worth reaching. But here is the twist that trips everyone up: a keyword is no longer an exact instruction, it is a hint. How loosely Google stretches your keyword to cover real searches depends on its match type, and modern Google leans hard toward matching broadly and letting its bidding work out who is actually worth showing to.

Keywords still matter enormously, because Search is the one place you directly tell Google which intent you want to buy. Choose keywords that match how your buyers actually search, in their words, not the way you describe yourself in your brochure, and you reach people at the precise instant they want what you sell. That intent is what makes Search different from every interruption-based ad: the person asked first.

A keyword controls far less than it once did. With broad match and Smart Bidding, Google decides which real searches your keyword triggers on, and some of them will surprise you. The only way to see what you actually paid for is the search terms report, and the only way to steer it back is negative keywords. So treat a keyword as a starting signal you then have to police, not a precise switch you set and forget.

You pick the keyword, but Google picks the searches, so watch what it actually bought you.
