Correction: Correction: in your Line Item settings, 'Display Creative' should be set to 'One or More', not 'As Many as Possible' as described in the video.

Step 1. Add a line item

In DFP, create a new order with a $0.50 line item.

Enter all of the inventory sizes that your website has.

{: .pb-img.pb-md-img :} 

Because header bidding partners return prices, set the Line Item Type to Price priority to enable them to compete on price.

{: .pb-img.pb-sm-img :} 

Set the Rate to $0.50 so that this line item will compete with your other demand sources at $0.50 ECPM.

{: .pb-img.pb-sm-img :} 

Set Display Creatives to One or More since we'll have one or more creatives attached to this line item.

Set Rotate Creatives to Evenly.

{: .pb-img.pb-md-img :} 

Choose the inventory that you want to run header bidding on.

By default, prebid.js will send the highest bid price to DFP using the keyword hb_pb.

This line item will capture the bids in the range from $0.50 to $1 by targeting the keyword hb_pb set to 0.50 in the Key-values section.

You must enter the value to two decimal places, e.g., 1.50. If you don't use two decimal places, header bidding will not work.

{: .pb-img.pb-md-img :} 

Step 2. Add a Creative

Next, add a creative to this $0.50 line item; we will duplicate the creative later.

Choose the same advertiser we've assigned the line item to.

Note that this has to be a Third party creative. The "Serve in Safeframe" box has to be UNCHECKED (there are plans to make the below creative safeframe compatible).

Copy this creative code snippet and paste it into the Code snippet box.

<script>
var w = window;
for (i = 0; i < 10; i++) {
  w = w.parent;
  if (w.pbjs) {
    try {
      w.pbjs.renderAd(document, '%%PATTERN:hb_adid%%');
      break;
    } catch (e) {
      continue;
    }
  }
}
</script>

{: .pb-img.pb-lg-img :} 

Make sure the creative size is set to 1x1. This allows us to set up size override, which allows this creative to serve on all inventory sizes.

Step 3. Attach the Creative to the Line Item

Next, let's attach the creative to the $0.50 line item you just created. Click into the Line Item, then the Creatives tab.

There will be yellow box showing each ad spot that you haven't uploaded creatives for yet. Since you've already made the creatives, click the use existing creatives next to each size.


In the pop-up dialog that appears, click Show All to remove the default size filters and see the 1x1 creatives. Include the prebid creative and click Save.


Back in the line item, go into the Creatives tab again, and click into the creative you just added.

Then, in the creative's Settings tab, override all sizes in the Size overrides field.

Save the creative and go back to the line item.

Step 4. Duplicate Creatives

DFP has a constraint that one creative can be served to at most one ad unit in a page under GPT's single request mode.

Let's say your page has 4 ad units. We need to have at least 4 creatives attached to the line item in case more than 2 bids are within the $0.50 range.

Therefore, we need to duplicate our Prebid creative 4 times.

Once that's done, we have a fully functioning line item with 4 creatives attached.

Step 5. Duplicate Line Items

Now let's duplicate our line item for bids above $0.50.

In the Prebid order page, copy the line item with shared creatives.

This way you only have 4 creatives to maintain, and any updates to those creatives are applied to all pre-bid line items.

For example, we can duplicate 3 more line items:

• $1.00
• $1.50
• $2.00

Let's go into each of them to update some settings. For each duplicated line item:

1. Change the name to reflect the price, e.g., "Prebid_1.00", "Prebid_1.50"

2. Change the Rate to match the new price of the line item.

3. In Key-values, make sure to target hb_pb at the new price, e.g., $1.00. Again, be sure to use 2 decimal places.

4. (Optional) Set the start time to Immediate so you don't have to wait.

Repeat for your other line items until you have the pricing granularity level you want.
