Compare
Put two to four campaigns, ad sets or ads side by side, read which one leads and whether the gap is reliable, and act on it.
Compare puts two to four items of the same level next to each other: their figures, a verdict on which one leads, their figures day by day and the settings that differ.
Open a comparison
- In Campaigns, select two to four rows and choose Compare.
- On a campaign, ad set or ad's detail, choose Compare with….
Meta and Google Ads items can be compared together. The address of the page keeps the items and the period, so you can share it with a teammate.
To add an item, choose Add campaign (or ad set, or ad) and search for it. Remove an item from its chip.
What it shows
| Section | What it says |
|---|---|
| Metrics | Spend, Results, CPA, ROAS, CTR, CPM, Frequency and Conv. value. The best in each column is in bold; the others show their gap to it. |
| Verdict | Which item leads on CPA and on conversion rate, and whether the difference is reliable. |
| Day by day | A chart of spend, results, conversion value, ROAS, CTR or CPM. |
| Settings that differ | Only the settings that are not the same: objective, budget, bidding, targeting, placements, creative and more. |
| Act on it | Changes you can prepare from the verdict. |
Figures are in one currency. Items in other currencies are converted at the latest rate, and the page says so.
How the verdict is decided
The leader is tested against every other item at 95% confidence, corrected for the number of items compared. Each item needs at least 10 conversions before a winner is named. Until then the verdict says how many more conversions are needed. The same method decides split tests.
Act on it
When the CPA leader is reliable, two actions are offered:
- Pause the others prepares a pause for every item but the leader.
- Move budget to the leader prepares, for each other item, a move of 20% of its budget to the leader, within the workspace's limit per change and its daily budget ceiling.
Both only prepare changes. They wait for approval in Priorities on Home: see Approvals and undo.
Watch for
- Compare one level at a time: campaigns, ad sets or ads.
- Drafts have no figures to compare. Rules cannot be compared.
- Move budget to the leader is not offered for ads, for items in different currencies, for lifetime or shared budgets, for sample data or for Performance Max asset groups.
