The Constant Bid Algorithm (also known as Force Product Visibility) is designed to generate initial traction and collect data for new or low-performing products. It works by setting an average suggested bid and maintaining fixed bids across your strategy to force initial engagement.
Why Use the Constant Bid Algorithm?
The main objective is to collect data that the algorithm can use later when transitioning to a more optimization-focused strategy like the Monthly Budget Management or ACOS optimization.
You can also use the Constant Bid algorithm If you prefer a more manual approach to optimizing your bids. This is especially helpful when using Focus strategies to push a small and select number of high value keywords (Ex. For a ranking strategy, etc.), and you want to manually fine-tune bids while maintaining control over your ad spend.
Main use cases (RESUME EDITING HERE)
Collect data. If a product is selling fewer than 5 units per week or has little to no historical data, this strategy helps gather enough clicks and conversions to transition smoothly into more optimization-focused algorithms (Monthly Budget Management or ACOS optimization).
Launching New Products. When launching a new product with no historical data, using the Constant Bid algorithm helps establish initial visibility. Although Astra will scrape competitor data and automatically populate your campaigns with initial keywords, you can help Astra learn faster by providing a shortlist of high-relevance keywords to provide more direction. These keywords should align closely with those used to build the product listing (highly relevant) ensuring relevance and higher conversion potential.
You can do so by:
Opening the left sidebar and click “Catalog”
Locate the Seed column
In the corresponding row for your ASIN, input your keyword list
Improving Keyword Rank with Focus strategies. To boost ranking for specific keywords, a product can be propelled to page one for a given keyword with a high fixed bid. It gives the product more exposure to help build sales history and reviews.
How to use the Constant Bid algorithm?
When you create a strategy, you can select an algorithm "Constant Bid", set a Suggested Bid and Daily Budget.
Note: Set your bid high enough to generate meaningful data. For instance, if the average bid in your category is $1.15, consider setting a slightly higher bid, around $1.50, to drive enough impressions and clicks to accelerate data collection.
To determine an appropriate starting bid under the Constant Bid Algorithm, you can:
Use Amazon's suggested bid in your campaign manager.
Refer to pre-researched bid data you’ve gathered for your category.
Whatever your product margin can support.
It's important to note, Astra does not set the initial bid for the Constant Bid Algorithm because bid amounts vary depending on factors like each seller's particular product margin, product category, and specific business goals.
How to switch to ACOS target strategy?
When the strategy has collected enough data (at least 5-7 ad sales in the last 7 days and an ACOS lower than 200%), the "Optimize Sales with ACOS Target" button will become available.
