1. Different concepts

The bid for an ad group is a price you set yourself.

The default bid is given by the system, which is generally the price selected by other competing products in the same industry and category when they are placed.

2. Different results

Default bid: The competitive price set based on the bid. For example, if you and your competitors bid the same, Amazon will display your ad based on your default bid and product weight.

Ad group bid: Competition for product ad positions. Your bid will determine the display position of your product, but this position is not fixed and will change over time and with product weight performance.

Amazon's official explanation of the default bid is: The default bid applies to all clicks unless you set a different bid for the keyword.

Your bid may change, depending on the bidding strategy you choose and the increase in the bid for the ad position. Once the default bid for an ad group is set, any bids you add in the future will be initially defaulted to that bid. Of course, the default bid of the ad group can be modified at any time, and the bid when adding a new delivery can also be modified and edited.

There are the following differences between Amazon's default bid and targeted group bid.

In their bidding strategy and delivery range.

The default bid is that Amazon automatically delivers and bids for advertising products, while the targeted group bid is that advertisers can choose certain specific advertising scenarios to deliver and set different bidding strategies.

Targeted group bidding can more accurately target the target audience group and adjust the delivery strategy according to real-time results.

In addition, the delivery range of Amazon's default bid is relatively fixed and is limited to various locations where the advertisement is displayed, while the targeted group bid can expand the delivery range by selecting different advertising scenarios, such as product pages, search pages, recommendation pages, etc. to obtain more traffic.

However, it should be noted that targeted group bidding requires the selection and management of delivery strategies, which requires more operations and energy.

What is the difference between the default bid and the bid in Amazon ad groups?

In Amazon ad groups, ad groups are composed of multiple ad units and keywords. The default bid is the default bid that the system uses when you add a new keyword or ad unit if you do not set a bid manually. In other words, this is an initial bid automatically generated for a new keyword or ad unit. The difference in bids refers to the specific bids you set for different keywords or ad units. The higher the bid, the easier it is for your ad to be displayed to potential customers. When setting bids, you need to consider the balance between cost and expected sales to ensure that you get the most return on your advertising budget.

The difference in the default bids for Amazon ad group bidding is as follows:

1. Automatic bidding: This is the default bidding method for Amazon ad groups, which is automatically adjusted by the system based on ad performance and competitor performance. Automatic bidding can help advertisers save time and energy, while also increasing ad exposure and conversion rates.

2. Manual bidding: In contrast to automatic bidding, manual bidding requires advertisers to set their own bidding prices. Manual bidding allows advertisers to better control advertising costs and also optimize advertising results.

In short, when choosing an Amazon ad group bidding method, advertisers need to choose a bidding method that suits them based on their actual situation and needs.
