Sorting reorders your units so the ones you care about come first. Combined with filtering, it is how you find the best value in a large plan rather than scrolling through it.
It applies to the unit sidebar and the grid alike, so the order you set follows you between them.
The Sort Options
Sort | Use it to |
Most Relevant | The default ordering. A reasonable starting point before you sort deliberately. |
CPM: low to high | Find the most efficient units first. The usual choice when working to a budget. |
CPM: high to low | Spot the units driving your average cost up, so you can decide whether they earn it. |
Impressions: high to low | Find your biggest-reach units regardless of price. |
Impressions: low to high | Surface low-delivery units that may not be worth keeping. |
Health Score: high to low | Put the units with the most complete, reliable data first. |
Health Score: low to high | Find units with missing or questionable data, so you can chase or drop them. |
Sorting By CPM
CPM is cost per thousand impressions, and it is the fairest way to compare a small unit against a large one. A cheap unit nobody sees can have a worse CPM than an expensive unit on a busy road.
Sorting low to high and working down from the top is the quickest route to an efficient plan.
*Note: Do not optimise on CPM alone. A unit can be efficient and still be in the wrong place for your campaign, which is why it is worth sorting inside a filter rather than across the whole plan.
Combining With Filters
Sorting inside a filter is more useful than sorting everything. A few worth trying:
Filter to Available, then sort by CPM: low to high — your best value from confirmed inventory.
Filter to one Vendor, then sort by Impressions: high to low — their strongest sites, for a negotiation.
Sort by Health Score: low to high — a quick data-quality review before sharing the plan with a client.
**Note: For a side-by-side comparison on several attributes at once, the grid is easier to read than the sidebar — you can sort and see the underlying numbers in the same view.
