What is Bid Testing?

Bid testing serves as a common media buying technique to uplift your results by manipulating the amount you offer Facebook for each impression in a bidding auction. 

How does bidding work?

The Bidding System on Facebook:

Facebook's entire advertising billing system is based on counting impressions. So just as an advertising platform is based on impressions, each ad placed on digital "real estate" is counted as one impression. 

Advertisers who offer the highest bid win the bidding war and are charged per impression. Since the competition is fierce, targeting specific audiences is more expensive. 

Bidding on Facebook 

Impressions on Facebook can be compared to commercial real estate spaces. Imagine Starbucks were to be placed in a rough neighborhood, no one would be willing to pay $6 for a latte. The same thing is true for Facebook real estate; if your ads aren't shown to the right audiences, then you might not be profitable. Cheaper audiences allow you to gain impressions from lower bids but aren’t always the most likely to buy your product or service.  

Using the manual bidding system will allow advertisers to reach different segments within their target audience. For example, if you want to reach 'Expensive' users within a specific audience, you can place higher bids; and to reach 'Cheap' users within a specific audience, you can lower the bids.

When using cost control bidding, you determine the bid according to your goals. Bid testing is used to control your reach within an audience and allows you to experiment with scalable audiences to find your best bids.

Bid Strategies Offered in Madgicx 

Different bid strategies are used to control your bids and are defined by your business goal. Madgicx offers four different bid strategies:

Bid Cap: Set a cost-per-event cap and Facebook will make sure that you get the minimum available bids up to your set limit and without exceeding this limit. 

Cost Cap: Set a cost-per-event cap and Facebook will search for opportunities to get impressions within this cap. The objective is to reach conversions within all audience segments. Facebook will try to reach audiences within your cap however if it doesn’t reach conversions within this cap it may go above or below your bid. 

Target Cost: Set a target cost-per-event and Facebook will only use your target bid without trying to get the minimum bids below set cost, assuring you are getting a consistent bid level.  


Value Cost: Input a minimum ROAS value and let Facebook optimize toward that value.
