What Is Amazon Bidding?

Amazon Advertising bidding is similar to an auction. 

Source

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.

This type of dynamic bidding is especially useful in scenarios where you need to maintain control over your advertising spend. These include periods when there is low demand. You can also use this method for campaigns that target high-cost keywords with low conversion rates.

When you adopt this technique, you won’t waste resources on redundant clicks. Your budget will be used more efficiently for opportunities that would more likely result in sales.

Do's 

  • Use during periods where conversions are lower
  • Use it to avoid overspending
  • Regularly review campaign performance

Don’ts

  • Don’t use it for high-conversion campaigns
  • Don’t set and forget
  • Don’t rely solely on automation

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.

Basically, the way this works is that you increase bids for clicks that are more likely to convert and reduce bids for clicks less likely to convert. 

This method is perfect for when you have variable conversion rates and want to improve your ad’s performance. What you do basically is to dynamically adjust your spending to focus on the most favorable opportunities.

Try this method when:

  • You have campaigns with variable conversion probabilities.
  • You want to invest in high-potential clicks and minimize costs for less promising ones.
  • You want to strike a balance between controlling your budget and maximizing conversions.

Do's 

  • Use for variable conversion rates
  • Maximize high-potential clicks
  • Balance budget and performance

Don’ts

  • Don’t ignore data
  • Don’t use it for fixed-budget campaigns
  • Don’t neglect optimization

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.

When you use fixed bids, you’re basically acting independently of the market. This might mean that you’re driven mainly by budget or other external factors.

Leverage Fixed Bids in these instances:

  • Product Launches: When you’re introducing a new product, try fixed bids. They give your product consistent visibility and spare you the headaches that come with having to adjust bids from time to time.
  • Brand Visibility Campaigns: Building brand awareness? Fixed bids work well for this. They make your ad spend more predictable while improving your brand visibility. 
  • Budget Control: Fixed bids have got your back when you need to stay within budget. They give you strict control over your ad spend.
  • Testing: Give fixed bids a shot when you’re experimenting with new ad formats or keywords. They help simplify the process by removing variability. This lets you measure performance without having to bother yourself with bid adjustments.

Dos 

  • Use it for consistency
  • Leverage it for testing purposes
  • Set clear budgets

Don’ts

  • Don’t ignore performance data
  • Don’t apply to all campaigns
  • Don’t neglect competitive analysis

Rule-Based Bidding

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

It simply means automating your bid adjustments based on preset criteria and conditions. 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.

Rule-based bidding helps you take charge of bidding strategies through automation. 

Here are some cases where you can use Rule-based bidding:

  • Campaign Optimization: Get the best out of your campaign by using rules to bump up bids for high-performing keywords and lower them for keywords that are not performing so well. Simply ensure they’re based on performance metrics such as CTR, conversion rate, or ROAS, etc.
  • Budget Management: Rule-based bidding is budget-friendly. With this method, you can set bidding limits. The rules you set automatically adjust your bids to stay within a determined budget.
  • Time-Based Adjustments: Put rules in place to boost your bids during high-traffic shopping hours or to lower them at not-so-busy hours. This way, you get to present your ad to prospects at a more appropriate time of the day.
  • Seasonal Campaigns: Seasonal promotions can make bids unstable. By setting rules for seasonal campaigns, your ads remain competitive during high-demand periods.
  • Targeting Specific Goals: Set rules to achieve specific business outcomes. An example is if you’re getting rid of old stock to make room for new goods. In this instance, you can set a rule to increase bids for keywords that have ‘discount’ ‘sales’ or ‘clearance’ by 30%. 

Do's 

  • Set clear objectives
  • Regularly review rules
  • Test and optimize

Don’ts

  • Don’t overcomplicate rules
  • Don’t ignore market changes
  • Don’t rely solely on automation

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: Be Clear on Your Ad Goals

Effective ad bidding starts with understanding your goals. This clear perspective on what you want to achieve is the foundation for other strategies. Ask yourself some crucial questions like: Do I want to increase my brand awareness? Am I interested in driving sales? Would I like to improve my product’s visibility? 

Your answers to these questions will give you clarity, allowing you to craft a solid bidding strategy.

Step 2: Research Keywords 

Carry out thorough research of keywords in your field to better understand what your target audience is looking for. Your job becomes easier when you identify relevant keywords your prospects are likely to use when searching for the products you sell.

Amazon's Keyword Planner is one tool that comes in handy when researching keywords. There are also other third-party software you can use to discover high-performing keywords.

Step 3: Set a Budget

Determine how much you want to set aside for bidding in your advertising budget. Remember to take your goals into consideration as you’re budgeting. Your budget should be realistic based on the prices of the current bids. 

Stay flexible. At the beginning of your campaign, you must monitor performance constantly; market forces can require you to adjust your budget. 

Step 4: 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 5: 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 6: 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.

Step 7: Leverage Performance Data

Data from your ad performance is super useful for effective ad bidding. It’s a must if you want to improve your Amazon ad strategy. When you analyze key metrics such as sales data, click-through rates, and conversion rates, you’ll easily identify which keywords and ads are performing well and which are not. 

For example, if data shows you that conversions peak between 3pm to 6pm, you could decide to increase bids by 25% during this period. This way, you’ll optimize the peak period and increase conversions. 

Monitoring and analyzing performance data is a continuous exercise, but it’s certainly a rewarding one. You get more bang for your buck plus insights that help you keep refining your bidding strategies.

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.
