Weekly Facebook Ads Check-Up: A 15-Minute Audit With AI

Most ad accounts don't fail in one dramatic moment. They drift. An ad that worked last month gets tired, a budget runs out early, a campaign quietly stops getting results. A short weekly check-up catches that drift before it costs you real money.

This guide shows you how to run that check-up by asking plain questions in Claude, ChatGPT or AdChat's built-in chat. It takes about 15 minutes once you've done it twice.

Who this is for

Small business owners, solo marketers and anyone who runs Facebook or Instagram ads but doesn't want to spend an hour in Ads Manager every week. You don't need to know the jargon. We'll explain the terms as we go.

What you need

• An AdChat account with your Facebook ad account connected. If you haven't done that yet, start your free trial.
• AdChat connected to your AI app, or the built-in chat at adchat.app.
• Write access is not needed. Everything in this guide only reads your data. AdChat is read-only until you turn write access on in your dashboard.

A few terms you'll see

• Spend: what you paid Meta in the period.
• Result or conversion: the thing you want, like a purchase, a lead form or a sign-up.
• CPA (cost per action): spend divided by results. If you spent $200 and got 10 leads, your CPA is $20.
• CTR (click-through rate): the share of people who saw your ad and clicked it.
• Frequency: how many times, on average, each person has seen your ad. High frequency often means people are getting bored of it.

Step 1: Get the big picture

Start wide. Ask for the whole account, last 7 days, compared with the 7 days before.

How did my ad account do in the last 7 days compared with the previous 7 days? Show total spend, results, cost per result and CTR, and tell me what changed most.

What a good answer looks like: a short table with both weeks side by side, the percentage change for each number, and two or three sentences that point at the cause. For example: "Spend was flat, but cost per result rose about 30%, mostly because the 'Spring Sale' campaign got fewer purchases."

If the answer is just a wall of numbers with no comment, ask a follow-up: "What's the one thing I should look at first?"

Step 2: Go campaign by campaign

List my active campaigns for the last 7 days with spend, results and cost per result. Sort them from best to worst cost per result and flag anything that looks off.

You're looking for three things:

1. A campaign that eats most of the budget but brings few results.
2. A campaign that's doing well but is limited by a small budget.
3. A campaign with zero spend that you expected to be running. That often means it's paused, out of budget, or an ad was rejected.

Step 3: Check the ads themselves

Campaigns hide a lot. One great ad can carry three weak ones.

For my active campaigns, break performance down by ad for the last 14 days. Which ads have the best and worst cost per result? Include frequency and CTR.

What a good answer looks like: a ranked list of ads with a clear winner and a clear loser in each campaign, and a note on any ad whose frequency is climbing while CTR is falling. That pattern is called creative fatigue, and it's covered in detail in the ad creative analysis guide.

Step 4: Look at who is seeing your ads

Break down last 14 days of results by age and gender, then by placement (Facebook feed, Instagram feed, Stories, Reels). Where is my cost per result lowest and highest?

This often turns up surprises. Maybe one age group converts at half the cost of another, or Stories eat budget without results. Don't act on tiny numbers, though. A group with two results isn't proof of anything yet.

Step 5: Ask for a short to-do list

Based on everything above, give me the three most important actions for this week, in order. For each, tell me why and what you'd expect to happen.

This turns analysis into a plan. Typical answers: pause a weak ad, move some budget from one campaign to another, refresh a tired image, or leave things alone because a campaign is still learning.

What to do next

• If the to-do list says "pause" or "cut", follow the wasted ad spend guide.
• If it says "scale" or "shift budget", see the budget optimization guide.
• If you need to share results with a client or boss, use the weekly report guide.

To make changes from the chat, you'll need to turn on write access in your AdChat dashboard. AdChat asks before it changes anything, and the built-in chat shows you the exact change first.

Common mistakes

• Judging on one day. Daily numbers swing a lot. Use 7 or 14 days for decisions.
• Comparing different lengths. Compare 7 days with 7 days, not a week with a month.
• Reacting to tiny samples. If an ad set has three results, its cost per result can change wildly with one more sale.
• Ignoring the learning phase. After you launch or make a big edit, Meta spends a few days figuring out who to show your ads to. Results are bumpy during that time. Read more in the budget guide.
• Skipping the follow-up. The first answer is a starting point. Ask "why?" and "what would you do?" until the next step is obvious.

FAQ

How long does the check-up take? About 15 minutes once you know the prompts. Save them in a note so you can paste them each week.

Can AdChat run this audit automatically every Monday? No. AdChat acts only when you ask. There's no background or scheduled mode, so you stay in control of when it looks and what it does.

Does it work on Instagram ads? Yes. Instagram ads run through the same Meta ad account, so they show up in the same data. Ask for a placement breakdown to see them separately.

I manage more than one ad account. Can I audit all of them? Yes, one at a time. Name the account in your prompt. See the guide for freelancers and small agencies.
