Segmenting inventory is the process of setting up custom channels so you can explicitly see how certain sections of your site or group of ad units perform versus another. It allows you to group relevant portions of the inventory so you can later easily run the reports and take action as necessary. It’s extremely useful because it allows easier visualization of the areas you need to work on.

Segment Inventory with Custom Channels
Custom Channels allow you to segment your traffic and review performance. With this strategy, you can compare how a certain group of ad units is performing versus the other, or how above the fold ads do against below the fold counterparts.
You have many options with Custom Channels unlike built-in reports because it’s something you can create and customize yourself and you are then able to quickly identify which part of the inventory needs attention.
Here are some examples:
Step 1: Countries
a) Tier 1 countries vs Rest of the world
b) US vs Rest of the world
c) Top 5 countries
Step 2: Inventory size
a) Large sizes vs Small sizes
b) Vertical sizes vs Horizontal sizes
Step 3: Device Category
a) Desktop + Tablet vs Mobile
b) Desktop vs Mobile
c) Desktop vs Tablet vs Mobile
Step 4: Site section
a) This applies if you have a separate set of ad units in different categories of the site or use Key-Value Pairs.
b) Homepage ad units vs Content ad units
News vs Sports
Step 5: Ad placement
a) Above the fold ad units vs Below the fold ad units
b) Mid-content units vs Sidebar units
