You can use the Google Ads API to set or update bids for Hotel ads.

> [!NOTE]
> **Note:** All non-zero bids (including bid adjustments) are eligible for property promotion ads (as long as [`AdGroup.type`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroupTypeEnum.AdGroupType.md.txt) is `PROMOTED_HOTEL_ADS`).

When configuring standard campaign-level bidding strategies, don't set the
[`bidding_strategy`](https://developers.google.com/google-ads/api/reference/rpc/v26/Campaign.md.txt#bidding_strategy) field (which is used only for portfolio
bidding strategies) or the [`bidding_strategy_type`](https://developers.google.com/google-ads/api/reference/rpc/v26/Campaign.md.txt#bidding_strategy_type)
field. The `bidding_strategy_type` field is read-only and is used only for
reading the current setting for a campaign.

For a **CPC%** or **Manual CPC** strategy, you can set or update bid amounts at
the ad group and listing group levels. For details, see
[Set CPC% or Manual CPC bid amounts](https://developers.google.com/google-ads/api/docs/hotel-ads/bidding/set-bids.md.txt#update-cpc).

> [!NOTE]
> **Note:** To set per-entity manual CPC bids (`cpc_bid_micros`) on specific hotel entities (`entity_bid.item_code`) in Search Campaigns for Travel (Search campaigns with AI Max for Search campaigns enabled, a linked hotel feed, and `MANUAL_CPC` bidding), use [`AdGroupCriterion.entity_bid`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroupCriterion.md.txt#entity_bid) (`CriterionType.VERTICAL_ADS_ITEM_BID`). See [Per-entity manual CPC bidding in
> Search Campaigns for Travel](https://developers.google.com/google-ads/api/docs/hotel-ads/travel-feeds#entity-bidding).

## Set CPC% or Manual CPC bid amounts

For CPC% and Manual CPC bid strategies, specific bid amounts need to be set at:

- The ad group level
- The listing group level on unit nodes of a listing group tree

However, although you must set the value at the ad group level, that value won't
be used by Hotel ads. Hotel ads use the value at the listing group level, which
overrides the value at the ad group level.

You can also control bid ceilings at the campaign level as part of setting the
bid strategy. For details, see
[Assign or update a bidding strategy](https://developers.google.com/google-ads/api/docs/hotel-ads/bidding/assign-strategies.md.txt).

### Set a bid on an ad group

The following code shows how to set a bid at the ad group level when creating a
new hotel ad group. To update an existing ad group's bid, send an
[`AdGroupOperation.update`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroupOperation.md.txt#update) with an `update_mask` containing
`cpc_bid_micros` or `percent_cpc_bid_micros`.


### Java

```java
private String addHotelAdGroup(
    GoogleAdsClient googleAdsClient, long customerId, String campaignResourceName) {
  // Creates an ad group.
  AdGroup adGroup =
      AdGroup.newBuilder()
          .setName("Earth to Mars Cruises #" + getPrintableDateTime())
          .setCampaign(campaignResourceName)
          // Sets the ad group type to HOTEL_ADS. This cannot be set to other types.
          .setType(AdGroupType.HOTEL_ADS)
          .setCpcBidMicros(1_000_000L)
          .setStatus(AdGroupStatus.ENABLED)
          .build();

  // Creates an ad group operation.
  AdGroupOperation operation = AdGroupOperation.newBuilder().setCreate(adGroup).build();

  // Issues a mutate request to add an ad group.

### Set a bid on a listing group unit node

As described in [Create Hotel listing groups](https://developers.google.com/google-ads/api/docs/hotel-ads/create-listing-groups.md.txt), Hotel ads
won't serve until you create a valid listing group tree with at least one unit
node. Nodes are objects of the [`ListingGroupInfo`](https://developers.google.com/google-ads/api/reference/rpc/v26/ListingGroupInfo.md.txt) class,
which contains the [`ListingGroupType`](https://developers.google.com/google-ads/api/reference/rpc/v26/ListingGroupTypeEnum.ListingGroupType.md.txt) field that indicates
whether a node is a `UNIT` or a `SUBDIVISION`. Setting `ListingGroupInfo` on the
`listing_group` field of [`AdGroupCriterion`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroupCriterion.md.txt) links the
`ListingGroupInfo` object to the [`AdGroup`](https://developers.google.com/google-ads/api/reference/rpc/v26/AdGroup.md.txt). You can set or update
bids on unit nodes by setting the `percent_cpc_bid_micros` field or the
`cpc_bid_micros` field of `AdGroupCriterion` (and including that field in the
`update_mask` when updating an existing criterion with
`AdGroupCriterionOperation.update`). Attempting to set bids on `SUBDIVISION`
nodes fails with an error.

When setting bids at the listing group level, note the following:

- Bids can be set only on `UNIT` nodes. In particular, you can't set a bid on the "All hotels" root node once it has been subdivided, because it is then a `SUBDIVISION`. (The simplest valid tree is a single root `UNIT` node, which carries the bid for all hotels in the ad group.)
- Google recommends not setting bids on "Other" nodes that are `UNIT` nodes. Bids on "Other" (`UNIT`) nodes can have unintended effects on other hotel ad bids.

The following code shows how to set a bid on a listing group unit node.


### Java

```java
private static String addLevel1Nodes(
    long customerId,
    long adGroupId,
    String rootResourceName,
    List<AdGroupCriterionOperation> operations,
    long percentCpcBidMicroAmount) {
  // Creates hotel class info and dimension info for 5-star hotels.
  ListingDimensionInfo fiveStarredDimensionInfo =
      ListingDimensionInfo.newBuilder()
          .setHotelClass(HotelClassInfo.newBuilder().setValue(5).build())
          .build();
  // Creates listing group info for 5-star hotels as a UNIT node.
  ListingGroupInfo fiveStarredUnit =
      ListingGroupInfo.newBuilder()
          .setType(ListingGroupType.UNIT)
          .setParentAdGroupCriterion(rootResourceName)
          .setCaseValue(fiveStarredDimensionInfo)
          .build();
  // Creates an ad group criterion for 5-star hotels.
  AdGroupCriterion fiveStarredAdGroupCriterion =
      createAdGroupCriterion(customerId, adGroupId, fiveStarredUnit, percentCpcBidMicroAmount);
  // Decrements the temp ID for the next ad group criterion.
  AdGroupCriterionOperation operation = generateCreateOperation(fiveStarredAdGroupCriterion);
  operations.add(operation);

  // You can also create more UNIT nodes for other hotel classes by copying the above code in
  // this method and modifying the value passed to HotelClassInfo() to the value you want.
  // For instance, passing 4 instead of 5 in the above code will create a UNIT node of 4-star
  // hotels instead.

  // Creates hotel class info and dimension info for other hotel classes by not specifying
  // any attributes on those object.
  ListingDimensionInfo otherHotelsDimensionInfo =
      ListingDimensionInfo.newBuilder()
          .setHotelClass(HotelClassInfo.newBuilder().build())
          .build();
  // Creates listing group info for other hotel classes as a SUBDIVISION node, which will be
  // used as a parent node for children nodes of the next level.
  ListingGroupInfo otherHotelsSubdivision =
      createListingGroupInfo(
          ListingGroupType.SUBDIVISION, rootResourceName, otherHotelsDimensionInfo);
  // Creates an ad group criterion for other hotel classes.
  AdGroupCriterion otherHotelsAdGroupCriterion =
      createAdGroupCriterion(
          customerId, adGroupId, otherHotelsSubdivision, percentCpcBidMicroAmount);
  operation = generateCreateOperation(otherHotelsAdGroupCriterion);
  operations.add(operation);

  return otherHotelsAdGroupCriterion.getResourceName();
