Bidding rules are applied to the bids calculated by Marin’s automated bidding algorithms in order to control or restrain bids based on your own business needs. They can be used to create a bid cap, a bid floor, a maximum bid change percentage and more, in order to make certain your Strategy meets your business' unique needs. 

Before you begin: Rules can be an incredibly valuable part of your optimization, however, since they can interfere with the algorithm's ability to make bidding decisions, it's important to validate the purpose of each rule and carefully consider its expected impact prior to implementation. 

If in doubt, opt for using fewer rules, instead of more rules, to give the bidding algorithm freedom to increase or decrease your bids without running into restrictions. And if you're ever uncertain what a rule does or if it's right for your business, don't hesitate to reach out to a platform representative or our Customer Support team to discuss how each rule fits as part of your overall bidding strategy. 

Summary Of Rules

Set a Bid Cap is the maximum allowable bid. For example, a bid cap of $100 means the bidding algorithm is not allowed to increase your bid over $100.

Keep in mind that a Bid Cap ignores your Strategy-level targets by placing a cap on the allowable bid. If your Strategy is performing well and Marin Bidding would like to increase keyword bids to reach your target, a Bid Cap can interfere with this optimization. 

Set a Bid Floor is the minimum allowable bid. For example, a bid floor of $5 means the bidding algorithm is not allowed to decrease your bid below $5. 

Keep in mind that a Bid Floor ignores your Strategy-level targets by placing a floor on the allowable bid. If your Strategy is not performing well and Marin Bidding would like to decrease keyword bids to reach your target, a Bid Floor can interfere with this optimization. 

Keep above First Page Bid causes the minimum allowable bid for Google keywords to be equal to the First Page Minimum Bid determined by the publisher.

Keep in mind that the Google First Page bid does not take efficiency into consideration and may not result in a well-optimized Strategy.

Limit bid change under % (Maximum Bid Change) is the maximum percentage that bids can change each day. For example, if Marin Bidding has determined that your current keyword bid is $1, but the ideal bid will eventually need to reach $5, then this rule will allow the change to take place incrementally. If your maximum bid change % is set to 25%, then Marin Bidding will make small increases of 25% over the course of several days or several weeks to meet your desired keyword bid, rather than making those changes all at once.

This rule controls the reactivity of a Strategy to market changes, often preventing the over-optimization of bids. It is strongly recommended to set this to a maximum of 25%. Consider lowering it if your keywords only generate 1 or 2 conversions per week on average.

Set a Search Impression Share Cap allows you to set an impression share cap on Strategies that are NOT bidding toward an Awareness Target. This means that even Strategies that are targeting a financial goal (CPL, ROAS) can have an impression share cap. For example, if you're bidding toward a CPL goal, an impression share cap will prevent the algorithm from increasing bids on keywords that are already sitting above the impression share cap. 

Note: There are three different types of Impression Share Caps. To use, you will select the one that best fits your bidding needs. You can only use one type of Impression Share Cap at a time.

Set a Top Impression Share Cap allows you to set an impression share cap on Awareness Targeting Strategies that are bidding toward Top Imp % (Top Impression Percentage). This means your Strategy is targeting the top of the page (anything above the fold on the Search Engine Results Page).

Note: There are three different types of Impression Share Caps. To use, you will select the one that best fits your bidding needs. You can only use one type of Impression Share Cap at a time.

Set an Abs. Top Impression Share Cap allows you to set an impression share cap on Awareness Targeting Strategies that are bidding toward Abs. Top Imp. % (Absolute Top Impression Percentage). This means your Strategy is targeting the very first ad position on the Search Engine Results Page.

Note: There are three different types of Impression Share Caps. To use, you will select the one that best fits your bidding needs. You can only use one type of Impression Share Cap at a time.

Maximum CPL allows you to set a lower efficiency target for Google keywords below the first-page-bid-minimum. This rule is designed to periodically re-test keyword profitability on Page 1 and should be set equal to the Target CPL or Margin when launching bidding for the first time. Consider setting a Maximum CPL higher than the Target CPL (or Minimum Margin lower than the Target Margin) for 1 week every 3-6 months. This will give keywords that have been bid down below the first-page-bid-minimum an opportunity to perform at the primary target in a changed market.

How To Set Up Bidding Rules

1.  Click on the Optimize tab  in the left-hand navigation. 
2.  Next select Strategies.
3. From there, double-click on the Strategy of your choice. This will launch the Strategy Side Panel, where you can adjust your targets, update settings, and apply Rules. 
   
4. Within the Side Panel (under the Settings tab), hover over the Rules section and click on the Edit button ('pencil' icon) when it appears. 
   
5. To add a new Rule, click Add.
   
6. Here, you can browse the available rules. Use the information from the Summary section of this article to determine which rules are right for your Strategy.
   When you see the Rule you would like to apply, simply select it. 
   
7. Once a Rule has been added to your list of active Rules, be sure to set the corresponding value, percentage, or threshold as-needed based on your Strategy's unique needs. For example, if you choose to enable a Bid Cap, be sure to also set the value of your cap (for example, $100).
   Be certain you've reviewed the recommendations listed in this article and know the impact of a specific rule prior to enabling. Also, keep in mind that over-use of Rules can lower a Strategy's efficiency, so you should err on the side of adding fewer Rules, rather than more Rules. If ever in doubt, don't hesitate to reach out to a platform representative. 
   
8. To edit an existing Rule, simply follow the steps above and adjust the value, percentage, or threshold as-needed,based on your Strategy's unique needs. 
9. To remove a Rule from your list of active Rules, click the Delete button ('trash can' icon) next to the relevant Rule.
10. When the desired rule thresholds have been established, click Save. 
    
11. That's all there is to it! The next time Marin's automated bidding runs, it will take your new rules into consideration and adjust your bids accordingly. 

How To Set Up Excluded Dates

How To Set Up Bid Overrides

Bid Overrides can be applied in single edit, multi-edit, or via a bulk upload. We'll explain how below. 

Note: For Marin's automated bidding to work best, we recommend using Bid Overrides strategically and only when needed. If you're uncertain if Bid Overrides are the right choice for you bidding goals, please reach out to a platform representative.

1. Click into the Accounts tab in the left-hand navigation. 
2. Next select Keywords.
3. Select the check-boxes next to the keywords you would like to override and click the Edit button ('pencil' icon).  
4. From the edit pane, select Set Bid Override.  
5. From here, you will simply turn your bid override on or off, and set an optional end date. 
   
6. If you would like to both set your Search Bid and enable a bid override at the same time, you can select Search Bid in the edit pane, set your bid, and click the check-box to enable bid override -- at the same time!
   
7. You can also create a bulksheet with bid overrides. Simply click on the Upload button in the top-right. You can learn more about bulk uploads in Marin from our dedicated article. 
   In your bulksheet, you'll use the Bid Override column to enable/disable overrides and the Override Until column to set an end date for your override, if needed. 
    
8. To see which keywords are using a bid override, use the Column Selector to add the Bid Override column to the grid. The values in this column will display as "Override" or "Off." 
   
9. To see full settings history for a specific keyword, double-click on the keyword/row where you would like see additional details to launch the Side Panel. 
10. That's all there is to it! The next time Marin's automated bidding runs, it will take your new bid override settings into consideration and apply them to keywords accordingly.
