Optimization

The optimization tab of your campaign looks like this by default. Let's find out what each feature means.

Bidding Strategy

You can set a Bidding Strategy:

• Normal - will spend your budget as fast as possible. If a current strategy is used, we try to bid on all incoming traffic that matches the campaign targeting.
• Balanced - will allocate your budget evenly throughout the day on an hourly basis. To enable it you must have Daily Max Spend set in the Basic Settings. The set Max Spend Daily Limit will be spread over 24 hours, and then each hour limit will be split into minutes and seconds, allowing us to bet with only that amount of money per hour, per minute, and second.

❗️

Pay attention to Balanced bidding strategy!

The Balanced bidding strategy may not work effectively when the traffic and/or Daily Max Spend limit are low. Uneven traffic flow during different times can cause these restrictions, leading to different capacity levels. The less money allocated per hour, the harder it becomes to distribute it evenly.

Recency Cap

Recency Cap – time since the last bid for the same user, when another bid can be scored (MIN 60 - MAX 3600). It makes it possible not to make a bid on the same user for a certain time, regardless of the frequency capping settings, to take into account the recency factor.

Exposure time multiplier

Exposure time multiplier - allows to decrease the bid price exponentially as the number of views per single user increases.

The reduced multiplier is calculated by the e^(-(x-1)/t) formula, where: x – impression number (possible values >1, if x=1 then coef value = 1), t – Decay Rate or an exponential time constant (possible values 1..100).

Exposure time multiplier value by impression count table:

Let's assume that the base bid price was set to $10, and the Decay Rate is set to 1. Then, according to the formula above, the first 3 impressions' bid prices will be decreased: $10, $3.68, $1.35.
Now, let's assume that we set the Decay Rate to 100. Then for the base bid price of $10, the first 3 impressions' bid prices will be decreased: $10, $9.90, $9.80.

As you can see, with a much higher time constant of 100, the bid price remains relatively stable for the first 3 impressions. This is due to the slower decay rate, which means that the exponential decay only becomes significant after a much larger number of impressions. When the time constant is high, the bid price remains fixed for a longer period of time. This prioritizes showing the ad to the user multiple times before significantly reducing the bid.

Bid Floor Price

The Bid Floor Price Incrementer overrides the bid price and forces the campaign to bid with a price that matches the bid floor from incoming requests + the value specified in the Bid Floor Increment field.

🚧

Works only if SSP passes the Bid Floor!

A lot of SSPs do not send the bid floor price at all, in such a case the Bid Floor Price Incrementer will lead to the fact that the DSP will not win the auction absolutely.

Tracking Pixels/URLs

You can set two types of tracking links for the campaign, that can be used for 3rd-party events tracking:

HTML Code - used for tracking pixels. It will be added to the ad markup of the campaign's creatives and fired each time SSP executes the ad markup.

Beacon URL - used for tracking URL. It will be added to the Target URLs of the campaign's creatives and fired each time the banner is clicked.

📘

Please note

Tracking pixel on the campaign level will override Global Tracking Pixel settings.

Attribution Links

Attribution Links provides a possibility to notify 3rd Party Network about user interaction with the ad(Impression, Click, Conversion). The Attribution links are fired when the Impression/Click/Conversion is tracked.

🚧

Tracking Pixels/URLs and Attribution Links difference

Tracking Pixels/URLs are added to ad markup and are fired by the SSP. As a result, the SSP is responsible for tracking and counting events. On the other hand, Epom DSP fires Attribution Links through S2S when the DSP itself counts the corresponding event. Hence, the DSP is responsible for counting the events.

Automatic filling Retargeting

Each time a bid, impression, or click is recorded to a Campaign, IFA or User ID of a user that triggered this event, can be automatically recorded to IFA List or User ID group.

You can either select an existing IFA List/User ID group, or create a new one to record IFAs/User IDs. This list can be then used for another Campaigns targeting.

Bidding Rules & Bid Modifiers

The Bidding Rules feature is designed to create different types of rules that can optimize the bidding according to your requirements.

The list of connected Bidding Rules for this campaign is on the Bidding Rules panel. You can also add new rules or edit existing ones via the Manage Bidding Rules button.

The Bid Modifiers feature is a micromanagement tool that allows you to apply different modifiers to the bids depending on the traffic source.

The list of connected Bid Modifiers for this campaign is on the Bid Modifiers panel. You can also add new modifiers or edit existing ones via the Manage Bid Modifiers button.

Max Bid Price(CPM) - bid price upper limit in the case Bidding Rules or/and Bid Modifiers are applied. The Bid Price can be modified with Rules & Modifiers, but it cannot exceed the Max Bid Price value.

When all the settings are done press the Save button. New Creative form will be displayed.
