Performance Tab – Analytics and Optimization options

Question

Accepted Answer

To turn a campaign into a success, you have to 
analyze its performance and 
optimize along the way. 
We know the drill! 
That's why we introduced a new tab when opening any of your campaigns, which is called The Performance Tab.
This article explores the most important aspects to monitor and optimize once the campaign has started.
Monitoring a campaign
Once a campaign is created and running, go to the Campaigns tab in the sidebar menu > click on the campaign you would like to monitor > head to the Performance Tab.
CPA Target Campaign

Impressions: The amount of traffic that your campaign received.
Conversions: The number of conversions received.
eCPM: Effective CPM, how much is paid per 1000 impressions.
Target cost: Amount you are willing to to pay
Real Cost: Real cost of  a conversion
Revenue:  Total amount of funds generated before removing any expenses.
Spending: How much you have spent
Spending Difference: Difference between "Spending" and "Target Spending"
Target Spending: How much you are willing to spend
CPM Campaign

You can see the performance of your campaign (say the last 7 days) and other important information like:
Impressions: The amount of traffic that your campaign received.
Win Rate: (if applicable) An indicator of how competitive your bid is versus the competition.
Conversions: The number of conversions received.
eCPM: Effective CPM, how much is paid per 1000 impressions.
Revenue:  Total amount of funds generated before removing any expenses.
Spending: The amount spent for the selected date range.
ROAS: (if applicable) Indicating the success of your campaign (only if you report the price/payout of the reported conversions).
Profit: How much you have actually earned from your campaign.
That's not all. You can get a lot more insights into your campaign by checking the table below:

Grouping options 
You can group by and view all the important metrics by clicking on anyone from the list—Geos, Creatives, Zone, Source, OS name, Browser Name, SSP, etc.
You can also add a secondary dimension and have better visibility on any combination, for example, Group by Zone + OS name (secondary dimension) or Zone + Geo.

The table displays the results of the group by selection and is the basis for your optimization.
What's new
Auctions represent the opportunities your campaign received (and had a chance to be displayed). 
Impressions show when the auctions were actually displayed.
Respectively, the win rate is the ratio between Auctions and Impressions. 
The Bid column shows you the CPM bid, whether it be flat price, different price per quality tier, or (in case you have a custom bid) per zone/source in your campaign.
Tips and tricks
1. Find the traffic that brings you the most Conversions or Revenue or highest ROAS – use the sorting options on the given metric (for example, sort by Conversions descending).

2. Use the granularity (group by) options and influence your win rate. 
2.1. Use cases
You want to:
raise your bid because you want to get more traffic because your ROAS and/or Conversion rate is great OR
lower your bid because your ROAS is marginally negative, and you want to start spending less and eventually turn profitable. 
How to do it:
Edit the bid by clicking straight into the corresponding cell. Enter the desired bid, move away from the cell, and you are done.
You can do that at the Country, Country+Quality Tier level, or zone/source level.
Country+Quality Tier - Bid Editing (CPM)

Custom Bid per Zone+Country - Bid Editing (CPM)

If a zone/source is not performing at all, you can block it straight away (you will need to remove the second filter in step 2).
