Supply-side platform

Imagine you want to sell some candy. You have a lot of candy, but you don't want to go around town giving the candy to everyone who wants it. Instead, you decide to go to a candy shop and tell the owner that you have a lot of candy to sell. The candy shop owner puts your candy on the shelf and sells it to customers who come in looking for candy.

In a similar way, a supply-side platform (SSP) is like the candy shop owner. Instead of candy, it connects people who want to sell advertising space on their website or app with people who want to buy that space. The people who want to sell advertising space are called publishers, and the people who want to buy the space are called advertisers.

The SSP acts like a middleman between the publishers and advertisers. It helps publishers sell their advertising space more efficiently by making it possible for advertisers to buy the space through an auction. The auction is conducted in real-time, which means that advertisers can bid on the space as soon as it becomes available.

The SSP also helps publishers earn more money from their advertising space by automatically deciding which ads to show to which users. This is done using data about the user, such as their location, age, and interests. The SSP uses this data to choose the most relevant ads to show to each user.

In summary, an SSP is like a candy shop owner for advertising space. It helps connect publishers and advertisers and makes it easier for them to buy and sell advertising space.
