If you want the rules to check the keywords as frequently as possible (for example, hourly), but don't want to apply the bid adjustments to the same keywords too often, in such cases the Limit the action frequency option comes to help.
Important❗️Action Frequency is not the same as Run Frequency. It's an optional rule setting that allows you to set the minimum amount of time until the action can be applied again to the same keyword.
How to use it?
You set a rule to increase CPT bids for well-performing keywords.
New conversions happen all the time, and you want the rule to stay up-to-date with the changes and constantly find new keywords that fall under the conditions. So, you set Run Frequency to Hourly > Every 3 hours.
However, you're worried that the same keywords, falling under the conditions every time the rule runs, might be changed too frequently. It may make it hard for you to trace the effect of those changes.
The new Limit Action Frequency setting solves that, acting as a so-called cool-down period for the keywords! You can set it to, for example, Every 3 days, and if a keyword has just triggered a bid adjustment, the rule won't check the same keyword again for 3 days.
Note. This functionality is only available for rules like changing keywords' bids or adjusting keywords' bids by target metric. You can set the Action Frequency while creating or editing the rule with one of these actions.
Available presets for the Action Frequency Limit:
To review and edit the Action Frequency you have set for your rules, check the Action & Conditions column on the Automation page.
To check the Run Frequency, see the Run Frequency column.
❗ Important notes:
If you edit the existing rule by changing its action from Change keyword bid to Adjust keyword bid by target metric and vice versa or by changing its frequency, the Action Frequency Limit counter will be reset and start over after you save the rule changes.
There are cases when rules overlap. Note, Action Frequency Limit cannot guarantee that the keywords will not be changed by another rule if they fall under that rule's conditions.
