An advertising checking bureau is like a helper that checks on advertisements to make sure they are doing their job correctly.
You know how sometimes you see a commercial or an ad on the computer or in a magazine or on a billboard? Well, that is an advertisement.
Businesses put up ads to tell people about their stuff. They want more people to know and like their stuff so that they can sell more of it.
But sometimes, businesses need help to make their ads better. That's where the advertising checking bureau comes in. They check the ads to make sure they are doing their job correctly.
They make sure the ads are pretty to look at and easy to understand. They also make sure the ads have the right information, like how much something costs or what it does.
Once the advertising checking bureau checks the ad and makes sure it's perfect, the business can put it out there for everyone to see!
