To compare Facebook campaigns with AI, ask an AI assistant connected to your ad account to put the campaigns you name in one table, or to set this period against the one before. It reads Meta's own totals for spend, results, cost per result, CTR, CPM and frequency, and tells you where the campaigns differ.
TL;DR
- There are two comparisons: campaign against campaign, and a campaign against its own past.
- Each campaign gets one row per period, with spend, results, cost per result, CTR, CPM and frequency.
- The numbers are Meta's own calculated rates, one total per period.
- Use the same dates for a fair side by side, and equal-length periods for a period comparison.
- For return and cost on their own, see ROAS by campaign and CPA by campaign.
Who this is for
- Media buyers choosing which campaign deserves more budget.
- Advertisers checking whether a new campaign beats the one it replaced.
- Agencies explaining to a client what changed since last month.
Connect your AI assistant to Meta ads
Ask about your ad accounts in plain words. Every change waits for your yes. Included in the 7-day free trial.
Try for Free ($0 Trial)The prompt to paste
In my Facebook ad account [account name], compare these campaigns side by side for the last 14 days: [campaign name], [campaign name] and [campaign name]. Show spend, results, cost per result, CTR, CPM and frequency in one table. Then compare each with the 14 days before and tell me what moved the most. Do not change anything.
Follow-ups that work well:
Which campaign has the highest CPM, and is its CTR making up for it?
Show the same comparison for the ad sets inside [campaign name].
The prompt works in any AI assistant connected to the Madgicx MCP. If yours is not set up, connect your AI assistant first.
What the MCP reads
- Results per campaign for each period. Spend, results, cost per result, CTR, CPM and frequency, as Meta calculates them, one total per campaign for the dates chosen.
- Campaign setup. Objective, budget and bid strategy, so the assistant can warn you when two campaigns are not alike enough to compare fairly.
- Ad sets and ads. The same totals one level down, to see what explains a gap between campaigns.
A trend needs two or more periods, because there is no day-by-day split. Ask for each period and let the assistant compare them.
What the answer looks like
A table with one row per campaign and period, and a column for each measure. Below it, a short read: which campaign costs less per result, which has the higher CTR, where frequency is high, and what changed most between the two periods. Campaigns with different objectives are flagged, since their results are not the same thing.
What to do next
- Dig into cost: CPA by campaign shows cost per result for every campaign.
- Dig into return: ROAS by campaign shows purchase ROAS and break-even.
- If frequency is climbing in the older campaign, check creative fatigue.
- If a comparison shows a clear drop, find out why performance dropped.
Changes happen only after you confirm
This page only reads. If you later ask the assistant to change something, such as pausing a campaign or lowering a budget, it must show you the exact change and wait for your confirmation before it runs. Nothing changes until you say yes.

FAQ
How many campaigns can I compare at once?
Name as many as you like. For a readable answer, compare up to five or six, or ask for the top campaigns by spend.
Can I compare a campaign with its own past?
Yes. Ask for the same campaign over two periods of equal length, such as the last 14 days and the 14 days before.
Can it compare campaigns across ad accounts?
It can read every ad account you can reach. Name each account in the prompt and it reads them one at a time.
Why are the campaigns not comparable?
Different objectives, budgets or bid strategies change what a result costs. The assistant flags this, so read it before you decide.
