# Sponsored Banners on landing pages

> Learn how to use the auctions API to create auctions specifically for landing pages

High-visibility locations like the homepage and landing pages (specially crafted standalone pages for marketing purposes) are excellent choices for displaying relevant and engaging banner ads.

To serve banner ads on these pages, start by configuring your banner slots. When making auction requests for landing pages, ensure that the `category` and `searchQuery` fields are left empty.

Here's an example with only one banner slot on the search results page on desktop:

```json theme={null}
{
  "auctions": [
    {
      "type": "banners",
      "slots": 1,
      "slotId": "backtoschool_banners_top",
      "device": "desktop"
    }
  ]
}
```

You can see a sample response with everything you need to serve the banner ads.

```json theme={null}
{
  "results": [
    {
      "winners": [
        {
          "rank": 1,
          "winnerType": "brand",
          "winnerId": "p_PJbnN",
          "resolvedBidId": "WyJlX1BKYm5OIiwiMTJhNTU4MjgtOGVhZC00Mjk5LTgzMjctY2ViYjAwMmEwZmE4IiwiYmFubmVyQWRzIiwiZGVmYXVsdCIsIiJd",
          "asset": [
            {
              "url": "https://topsort.cdnprovider.com/lhs-banner-image-for-p_PJbnN-1x.png"
            }
          ]
        }
      ],
      "error": false
    }
  ]
}
```
