The Bid Finder is meant for keywords that don’t have any clicks yet. It raises the bid step by step so the keyword gets visibility and gathers data. The Bid Optimizer handles keywords that are already performing and adjusts the bid based on actual results. They complement each other and both run daily, the Bid Finder at 14:00 and the Bid Optimizer at 15:00.
Yes, but they won’t touch the same keyword on the same day. The Bid Finder only handles keywords with zero clicks. The Bid Optimizer only handles keywords that have enough data. As soon as a keyword starts getting clicks and meets the triggers, the Bid Optimizer takes over from the Bid Finder.
Once a day, at 15:00. The bids are then sent to Bol right away. Processing on Bol’s side can take a few minutes.
Yes. Paused campaigns are included in the calculations. The bids are adjusted so they’re at the right level as soon as you resume the campaign.
There are a few possible causes. The keyword doesn’t meet one of the three triggers based on data from the past 7 days. The calculated new bid is equal to the current bid, in that case the system skips the update. Or the combination from old bid to new bid is identical to the previous adjustment in the history, in that case the update is blocked as well.
That’s exactly how it’s supposed to work. If your ACOS is well below your target ACOS, it means there’s room to bid more and capture more volume. The Bid Optimizer uses that room by increasing the bid, always limited by your max. CPC and change rate.
The change rate determines how much the bid is allowed to change per day at most, expressed as a percentage. The min. and max. CPC are absolute limits that the bid is never allowed to go beyond. They work together: the change rate limits the daily step, the min/max CPC limits the total range.
No, the change rate prevents that. If your change rate is 15%, the bid will never drop or rise by more than 15% per day, even if the calculation would justify a bigger adjustment. Large corrections are spread out over multiple days.
The Bid Optimizer has already adjusted the bid as far as possible. If a keyword structurally stays at the min. CPC and doesn’t convert, it’s the Keyword Remover’s turn. That one checks whether the keyword still has any value at all for your campaign.
Broad match keywords match on queries that are too broad to base reliable ACOS conclusions on. The data is a sum of dozens of different search queries. It would be too risky to adjust bids based on that. The Bid Optimizer only works on EXACT and PHRASE.
The new settings will be applied the next day. With every run, the Bid Optimizer uses the rule set as it’s configured at that moment. If you change the max. ACOS, the system will calculate with the new value the next day.
Yes. Turn off automation at campaign level. The campaign will then be skipped in all daily automations, including the Bid Optimizer. Other campaigns will just keep running.
Check if all required fields in your rule set are filled in. The Bid Optimizer requires max. ACOS, max. CPC, change rate and max. keyword budget to all be greater than zero. If one is missing, the rule set will be skipped.
For most situations, 10 to 20% works well. Lower means the system adjusts more slowly but is more stable. Higher means faster corrections but also a higher chance of fluctuations. Start conservatively and only increase it if you see that the system is reacting too slowly to changes in your campaign.
In the keyword report you can see the bid history per keyword. Every change made by the Bid Optimizer is logged with the old and new bid, the date, and the reason for the change.
That depends on how far your current bids are from the optimum and how high your change rate is. Count on at least one to two weeks before you see a clear movement in your ACOS. The system makes adjustments daily, but large corrections are spread out over multiple days.
First check if the Bid Optimizer is picking up the right keywords via the keyword report. Then see if your click threshold is realistic, because a threshold that’s too high means the system waits a long time before stepping in. Also check whether your max. ACOS matches what your product can handle commercially. If your target is unrealistically low, the system will keep pushing bids down without ever finding a balance.
