Advanced Algorithmic Optimization Settings

Note: In most cases, the values chosen by the optimizer will deliver the best results and there is no need to use advanced settings. You should set advanced optimization settings only if you have a specific plan to override the automatic settings. 

These optional settings give you more control over how you would like the optimizer to act. If you do not select Advanced optimization settings, then Basis DSP calculates these values for each campaign based on the other parameters you have set for it.

If you select Advanced optimization settings, you should change all of the preset values for the advanced options, based on your campaign's goals.

For CTR and VCR


  • Bid Step: Amount by which the CPM bid is going to increase every 12 hours. 

    • The preset value is $0.10.

  • Impression Threshold: Minimum amount of impressions required in a two-week period before the optimizer turns off a placement or domain if it is not meeting the Optimization Goal.

    • The preset value for CTR is 1,000 impressions per placement or domain. 

    • The preset value for VCR is 500 impressions per placement or domain. 

  • Smart Disable: By default, the optimizer only disables domains/placements if:
    • The CTR is below goal.
    • The CTR is below the tactic’s eCTR (the average click-through rate for the tactic).

If the CTR is below goal, but above the tactic’s eCTR, the domain/placement is not disabled. This is done so we don’t hurt the tactic’s overall CTR by disabling domains/placements that are performing better than average. Smart Disable lets you override this default. 

Note: The Optimizer will start making changes after the equivalent of two days' budget has been spent. 



  • Minimum bid: Minimum CPM bid that will be given to a placement or domain.

    • The preset value is 1/4 of the Default CPM Bid value you set in the Budget section. 

    • Turn off placements at Minimum Bid: Option to turn OFF placements or domains once they reach the Minimum Bid, otherwise the placements or domains stay ON at the minimum bid value.

  • Bid Step: Amount by which the CPM bid is going to increase or decrease every 12 hours.

    • The preset value is $0.10 for all.

  • Learn Budget: Minimum amount of the campaign's total media spend required before the Optimizer starts changing the CPM bid prices of individual placements or domains.

    • For campaigns using a Daily Budget: the preset value is the Daily Budget x 4.

    • For campaigns using an All Time Budget: the preset value is (Total Budget / Number of days in flight) x 4.
