ELI5: Explain Like I'm 5

Insert (advertising)

Okay kiddo, so you know how when you're watching a show or playing a game online, there are sometimes little commercials in between? Those commercials are called "ads" and they are there to tell you about something that someone wants you to buy.

Insert advertising is kind of like that, but instead of being in the middle of a show or game, it's on a website.

When you go on a website, there are sometimes little boxes or pictures that show you something that someone wants you to buy. That's what an insert ad is. It's like someone put a little commercial in the middle of the website.

The people who make these insert ads want you to see them and click on them so you can learn more about the thing they want you to buy. Sometimes, they even give special codes or deals to get you to buy it.

So there you have it, insert advertising is when someone puts a little commercial on a website to try and get you to buy something. Cool, huh?
