Smart Bids feature automatically adjust your bids each day based on its target ACOS. Smart Bids works for both automatic and manual campaigns using the target ACOS and conversion rate data of a keyword or target to calculate its target cost per click. Smart Bids then make small daily adjustments to your target's bid to bring its actual cost per click to its target cost per click.
In your Merch Jar settings, you'll find options to adjust how your Smart Bids optimizes your keywords and targets. The default target ACOS is the target ACOS that all of your campaigns will inherit unless overridden by a new target ACOS set at the campaign level. The minimum bid sets the lowest possible bid your keywords and targets can be set to for both Smart Bids and manual bid adjustments.
If Smart Bids or a manual bid adjustment were to decrease a target's bid below the minimum bid, it will instead be set to the bid selected in your minimum bid settings. The maximum bid sets the highest possible bid that your keywords and targets can be set to for both Smart Bids and manual bid adjustments. If Smart Bids or a manual bid adjustment were to increase a target's bid above the max bid, it will instead be set to the bid you've selected in your max bid settings.
For example, if you have a target ACOS of 24% and a target ACOS threshold of 2%. Any targets that have an actual ACOS between 22 and 26% will not have their bids changed by Smart Bids. The max bid adjustment is the maximum amount that smart bids will increase or decrease a keyword or target's bid each day.
Smart Bids will adjust any keywords and targets that have at least two or more orders in the last 30 days. Not including today's or yesterday's data. The percentage change that Smart Bids makes to your target bids is based on how far away its actual ACOS is from its target ACOS the further away the actual ACOS is from its target ACOS, the larger the adjustment will be up to the percent that you set for your max bid adjustment in your Smart Bids settings. Smart Bids is enabled at the campaign level and will monitor and make adjustments to any keywords or targets within a Smart Bids enabled campaign.
To turn on Smart Bids for a campaign, navigate to your campaign’s page and use the Smart Bid Switch to enable Smart Bids for that campaign. To turn off Smart Bids for a campaign, simply press the switch again to disable it. Before turning on smart bids for a campaign, you can use the Smart Bids dry run feature to see every bid adjustment that Smart Bids would make if enabled but without impacting your live campaigns.
In the logs page, you'll be able to see a history of every bid adjustment that Smart Bids makes to your keywords and targets, showing you the amount of the bid adjustment and the reason why it was adjusted using your actual ACOS and target ACOS.
