What Is Amazon Bidding?

Amazon Advertising bidding is similar to an auction.

Sellers and marketers compete for visibility and traffic by bidding on keywords that customers use when searching for products. The highest bidder is typically the one who will appear in the sponsored search result at the top of the page when a customer searches for a product.

How Does Amazon Advertising Bidding Work?

Amazon Advertising bidding works on a cost-per-click (CPC) basis. 

The advertiser pays each time an Amazon shopper clicks their ad. These clicks are charged at the bid amount you set for each keyword or slightly less depending on your competitors' bids.

The bid price you set and the rules you establish for automatically or manually adjusting that bid will impact everything from sales and profit margins to campaign ROI. And because the demand for certain keywords is dynamic, your bids must be regularly monitored to remain competitive and maximize results.

Different Amazon Bidding Methods

With the basics out of the way, it’s time to talk strategy. This is important—how you bid on Amazon can greatly affect your ROI. The name of the game is bidding enough to get the impressions, conversions, and sales you need without overspending.

Dynamic Bidding (down only)

With few conversion opportunities, this method lowers your bids in real-time to optimize your budget for quality clicks.

Dynamic Bidding (up and down)

This type of bidding adjusts bids based on conversion probability. It ensures optimal investment and minimizes costs in ineffective areas.

Fixed Bids

This method means choosing a default bid and sticking with it. Although fixed bids are not recommended in most cases, they can be useful for product launches or increasing brand visibility.

Rule-Based Bidding

Rule-based bidding involves setting up rules that control bids.

This method is effective when you want to maximize the return on advertising spend (ROAS) for your brand and certain products. When your campaign is approved, you can use Amazon's recommended RoAS guardrail, which appears in the input area, or create your own.

Why Is Amazon Advertising Bidding Important?

Targeted Audience Reach

Ad bid strategies allow advertisers to reach their intended demographic efficiently. Advertisers can ensure their ads are presented to the most relevant audience by bidding on specified keywords, demographics, or geographic locations. This increases the possibilities of conversion and generates a larger ROI.

Improved Ad Placement

Effective bidding is the only way to score profitable ad placements without exceeding your budget or hurting your margins too much. Advertisers who better understand keywords and their competition’s bidding strategies can secure the most profitable ad placements.

Better Cost Control

Cost control means assessing and scrutinizing all expenditures related to a business operation to identify places where costs might be cut or eliminated. Amazon bid management allows you to set your maximum cost per click and target a return on investment figure. You can also use it to optimize bids for higher search engine rankings and test different keywords and campaigns at little or no cost.

How to Do Effective Amazon Advertising Bidding

Step 1: Adjust Bids by Placement

Adjust bid by placement (formerly Bid+) is another tool in your arsenal for automating bid adjustments and maximizing exposure.

How does it work? It allows you to customize your bid adjustments based on where the Sponsored Ad appears (either on product pages or at the top of the search). This way, you can focus on bidding more for placements that are performing better and less for those that aren’t.

If you use sponsored ads to reach more people and increase sales, using an Amazon Advertising tool like Merch Jar is your best bet. With the Smart Bids feature, you can optimize ads and make bid adjustments to your ACOS goals without lifting a finger.

Step 2: Adjust Bids for New Campaigns

You may be unclear about what to bid when setting up a campaign for the first time. If so, we recommend you use Amazon's suggested bids. When you choose an Amazon-suggested bid, Amazon will research your competitors to determine a suggested bid range for a given term or phrase.

This range is a guideline, not a guarantee—you can adjust your bids according to the performance of the term or phrase. You may find that a high bid brings more relevant traffic than a low bid on certain terms, but that may not be worth the costs. Experiment with different bidding strategies as your campaign progresses.

When adjusting bids for new campaigns, remember:

  • Sales for new products may take some time to ramp up
  • Compare the costs of keywords and phrases using ROAS
  • Test different bidding strategies to determine which works best for your products

Step 3: Adjust Bids by Target ACOS

Amazon Advertising Cost of Sales (ACOS) serves as a gauge for evaluating the effectiveness of your Amazon pay-per-click (PPC) ads. It's the ratio of ad spend to total sales attributed to that ad.

The tricky part in adjusting bids by ACOS is finding a target ACOS that works. ACOS generally sits somewhere between 25% and 40%, but that isn’t a hard and fast rule.

Once you have a target, you can calculate a big using the following formula:

  • Target ACOS x Conversion Rate (CVR) × Average Order Value = Ideal Cost Per Click (CPC)

So, if your ACOS objective is 30%, your CVR is 12%, and your AOV is $54, you'll need a CPC of $1.94 to meet that aim. The difficult aspect is identifying the target ACOS that actually works for you—beyond that, it's just a matter of working with the numbers you already have.

With Merch Jar, you can eliminate the need for formulas by automating your bids according to your target ACOS. Enter your goal, and Merch Jar’s Smart Bids will cover the rest. You can even view detailed logs to track changes to your bidding strategy to uncover success patterns.

How to Calculate the Optimal Bid

Use the formula below to determine the best bid.

  • Bid = Maximum CPC = Average. Order Value multiplied by Conversion Rate multiplied by ACOS Target

Alternatively, the equation can be expressed as follows:

  • Bid = Maximum CPC = (Ad Sales / Ad Orders) × (Ad Orders / Ad Clicks) × (Ad Spend / Ad Sales)

Furthermore, the formula can be reduced as follows:

  • Bid = Maximum CPC = (Ad Sales / Ad Clicks) × (Ad Spend / Ad Sales).

While these calculations are designed to assist you with the Amazon bidding process, the ultimate goal is maximizing your earnings while lowering costs.
