# Ad group bidding parameters

### Bidding update options

The update default bid selector offers various options for adjusting bid amounts for ad group records. Each option provides different ways to adjust bids, either by a fixed amount, a percentage, or setting it to a predefined default.

### Bidding boundaries

Bidding boundaries are predefined limits set on advertising bid amounts to control and optimize spending. They include maximum and minimum thresholds for bid adjustments, ensuring that bid increases or decreases stay within a specified range. These boundaries are critical for maintaining a budget and strategy, preventing excessive spending or overly conservative bidding. They provide a controlled environment for bid management, especially in automated or bulk bid adjustment scenarios.

Bidding boundaries are dynamic, triggered by the specific bidding update scenario. These flexible and context-specific boundaries allow for more precise and strategic bid adjustments within the framework of an advertiser's overall budget and campaign goals.

{% tabs %}
{% tab title="Use maximum boundary" %}
Enabling this option sets a cap on bids to ensure that any increase in bidding does not exceed a certain value, providing a ceiling for bid amounts.

To assign a maximum boundary, select the "Use maximum boundary" checkbox and enter the maximum value you wish to assign.

**Examples:**

In an account with a minimum bid of $0.10 and a maximum bid of $2.40:

* Increasing a record with a bid of $0.50 by $2, with a maximum boundary of $4, would result in a $2.40 bid due to the account's max. bid limit.
* Increasing a record with a bid of $0.50 by $2, with a maximum boundary of $1.50, would result in a $1.50 bid.
  {% endtab %}

{% tab title="Use minimum boundary" %}
Enabling this option sets a floor for bids, ensuring that any decrease in bidding does not fall below a specified value.

To assign a minimum boundary, select the "Use minimum boundary" checkbox and enter the minimum value you wish to assign.

#### Examples:

In an account with a minimum bid of $0.10 and a maximum bid of $2.40:

* Decreasing a record with a bid of $0.50 by $2, with a minimum boundary of $0.05, would result in a $0.10 bid due to the account's min. bid limit.
* Decreasing a record with a bid of $0.50 by $2, with a minimum boundary of $0.15, would result in a $0.15 bid.

{% hint style="danger" %}
Bidding boundaries are overridden by account-level boundaries, specifically the minimum and maximum bid settings at the account level.
