I. We recommend the default 20% change rate to consider data delay and sales attribution. However, you can adjust to increase or decrease the speed of bid change until it reaches the calculated optimal bid.

II. You can individually assign the change rate at PGN, Campaign, and Ad group level rule configuration or even down to keyword or target level custom rules.

III. Change Rate does not affect the AMOUNT of bid we calculate, it just specifies how fast we reach to the optimal bid from the current bid. 1% is the slowest bid change rate where 100% is the fastest way to reach the new calculated bid.

IV. Putting 0% will disable Automate and Bid Gambler Automation.
