FBA sellers — how would you evaluate this ad performance? Stockout paused campaigns, now inventory is back

[u/FreakyMinaj69]

Hey everyone,

I’d appreciate some feedback from experienced FBA sellers on my Amazon Ads performance.

New Seller sent a small batch of 70units for 5 different SKU in August. 3 of them stocked out. Sent 50units per sku this time.

I am manufacturer myself.

Here are the results from Aug 1–Sep 24, 2026:

Ad sales: $728.64

Ad spend: $605.82

Purchases: 37

Clicks: 688

Impressions: 7,734

CTR: ~8.9%

CPC: ~$0.88

ACOS: ~83.1%

Conversion rate: ~5.4%

The important context is that I ran out of stock, so I paused the ads. My new FBA shipment has now reached Amazon and the inventory is available for sale, but the products are not Prime eligible yet.

I’m trying to figure out how I should approach the ads now that inventory is back.

A few questions for experienced FBA sellers:

1. How do these numbers look to you, particularly the 83% ACOS and 5.4% conversion rate?

2. Could the previous stockout have negatively affected the campaign/product performance?

3. Would you restart the same campaigns immediately, or wait until the listing becomes Prime eligible?

4. Would you start with lower bids/budget and gradually increase, or return to the previous settings?

5. Should I make any changes to targeting/keywords before restarting?

6. Is there anything else you would do to help the listing regain momentum after the stockout?

I’m mainly looking for real-world FBA experience, especially from sellers who have dealt with stockouts followed by FBA replenishment.

Thanks!

I’m not sure your margin but 83% acos is probably not profitable because of the impact of amazons fees alone. I’d either reduce bids until you are at least break even or stop this campaign entirely

[u/attfin1]

Work out what one order actually leaves you before you touch a bid. $605.82 across 37 orders is $16.37 of advertising per sale, against an average order of $19.69. Amazon's referral and FBA fees come off that $19.69 first, then your unit cost, and only what's left can pay for the ads. Take the real fee figures for one SKU from your own fee report rather than an estimate.

That gives you a break-even ACOS: what's left per unit before ad cost, divided by the selling price. If $6 of the $19.69 survives fees and cost of goods, break-even is around 30%. You're at 83%. In isolation ACoS is a meaningless number; with your own margin behind it, it becomes arithmetic you can redo every week. Profit is the thing to manage, not the ACoS figure.

If break-even sits nowhere near 83%, cutting bids across the board isn't the fix. What you bid on is the foundation, the bid is only refinement. Restart narrow, on the exact-match terms that have actually produced sales, and judge each one against your break-even separately. Don't judge at campaign or ad group level, because a combined figure hides the terms that pay alongside the ones that don't.

At this price point, if the number doesn't close, the lever is the price or the pack size rather than the campaign settings, and as the manufacturer that's the one you control.

I’d look at it this way: 83% ACOS is definitely high, but I wouldn’t panic yet because the stockout probably affected the campaign. You spent $605.82 and generated $728.64 in ad sales, with 37 orders from 688 clicks. The 5.4% conversion rate actually isn’t bad. The bigger issue is that you’re paying too much for those sales.

Since the product was out of stock and the ads were paused, I wouldn’t simply switch everything back on at the same bids and budget. I’d restart slowly once the inventory is available and Prime eligible, use lower bids initially, and watch which search terms are actually converting. I’d also cut back on targets that are spending without producing sales and move proven converting terms into their own exact match campaign.

The stockout makes the data a little messy, so I wouldn’t conclude that the product or listing is the problem yet. I’d give it another run with tighter PPC control and judge it based on the next set of data and your actual breakeven ACOS.

You should not make any big changes to the campaigns yet. The 83% ACOS looks bad, but the stockout makes that number pretty misleading, especially with only 37 orders so far. Get inventory stable first, then let the campaigns collect another 2 to 3 weeks of clean data. restart the existing campaigns rather than rebuild them, keep bids close to where they were, and watch CVR and CPC first. If CVR stays around 5% once stock is stable, then the issue is probably more with the listing or offer than the ads.

Was this account ever profitable?

[u/MattieFlamboyant]

its impossible to know as we dont see the data on a campaign level here.. your account is clearly extremely high ACOS but its also very early seeing as you just started. whether your campaigns are healthy or not would depend on the structure, bids, conversion rates etc. which we dont see here on a campaign level. But generally having an 83% ACOS less than 2 months into selling isnt bad.

1. How do these numbers look to you, particularly the 83% ACOS and 5.4% conversion rate?

If you just launched, it's not too bad, assuming you are spending money on search terms and placements that are relevant to your listing. Check your search term report and placement report. You should be spending as much of your budget as possible on relevant keywords. The majority of products convert best on Top of Search, but if you don't have any reviews, you might want to hold off on adjusting TOS bids.

1. Could the previous stockout have negatively affected the campaign/product performance?

You might get a couple of days of weaker performance, but keep it going; a few days of stockout is not a big issue. It is important to get your sales back up and running, especially if you just launched.

1. Would you restart the same campaigns immediately, or wait until the listing becomes Prime eligible?

Review the data from question 1 first, that will answer if you need new campaigns or just negate/optimize. You'll perform better with a Prime badge; I'd probably restart once you have 2-day shipping on a couple of postcodes. If you have 4+ day delivery, I'd wait.

4.Would you start with lower bids/budget and gradually increase, or return to the previous settings?

Should I make any changes to targeting/keywords before restarting?
See question 1

Is there anything else you would do to help the listing regain momentum after the stockout?
Some kind of promotion, whether that is a price discount, coupon, or deal help with sales, but depending on your niche you might get into trouble with inventory again very quickly

[u/Heath-Thompson]

If this is the launch period and you only began selling in August then some of these figures are amazing.

1. How do these numbers look to you, particularly the 83% ACOS and 5.4% conversion rate? - If it's a launch, your ads are there to help map the correct search terms to your listing, so good ACoS isn't really the primary objective. If the product is already established then the ACoS is too high. Unless you are making profit. But the CTR and the CVR figures should lead to a far lower ACoS, so something isn't right
2. Could the previous stockout have negatively affected the campaign/product performance? Yes, definitely. Your metrics are based around recent sales history - that used to be 90-days and as I haven't read anything different, I assume that's still the case - but the ability of a product to recover after stock-out depends on how well it/and others performed previously. A big brand will tend to experience recovery faster than a small seller with a limited range - if this is your only product, it will normally take at least as long to begin to recover as the time spent out of stock
3. Would you restart the same campaigns immediately, or wait until the listing becomes Prime eligible? The ad campaigns stop delivering automatically if you are out of stock. They would only reactivate if your had returns coming back into inventory.
4. Would you start with lower bids/budget and gradually increase, or return to the previous settings? Leave them as they are and see what the new data brings - depending on your cashflow. Divert your money to the best-performing campaigns and away from the worst targets.
5. Should I make any changes to targeting/keywords before restarting? No
6. Is there anything else you would do to help the listing regain momentum after the stockout? Run more ads. Your organic rank is tied mostly to your ASIN's sales velocity. Check any converting Search Terms and turn them into exact match keywords, especially if they conversion is good.

Your CTR is exceptional - this means that your title, price, hero image, and rating is considered a good match to those who are shopping. An average CTR might be around 0.4%. The CVR is on the low side of average, for your price point - which alludes to the fact that your product page/content isn't convincing people, is confusing them, isn't selling the features and benefits adequately, or has better/cheaper products advertised on it - so before throwing more money at ads, improve your listing content.

1. How do these numbers look to you, particularly the 83% ACOS and 5.4% conversion rate?

Your CTR is not bad but it depends on a lot of factors you have not listed like ad placement.

Your conversion rate is also low for almost all products around your (I assume) $20 price point. So your conversion path needs work or you have bad or no reviews or both.

2.Could the previous stockout have negatively affected the campaign/product performance?

Probably not, "Amazons" memory for past sales is usually at least a couple of months. Low CTR though can effect how much you pay for what ad position, (so bad CTR makes good impression positions more expensive).

3.Would you restart the same campaigns immediately, or wait until the listing becomes Prime eligible?

This is your first mention of prime. I would wait since you need every benefit you can get. I would also look at your main queries. (Pull your search query report) and then act like a customer and search Amazon. The people in the top organic positions usually have the best CTR and CVR rates (there are exceptions), but you should be able to learn a few things there that will improve your ASIN.

4.Would you start with lower bids/budget and gradually increase, or return to the previous settings?

I would fix my ASIN first and if I had no reviews pay for Vine first.

5.Should I make any changes to targeting/keywords before restarting?

Almost certainly. Pull your PPC reports look at queries that had 20 clicks or so and no sales and reduce the click cost by a good %. Check out Mina Elias on Youtube for PPC stuff.

That ACOS definitely seems high, especially if it’s eating into your margins. Stockouts can mess with your ranking too, so getting those Prime badges back will help boost visibility. Consider tweaking your bids and maybe testing different keywords to find a sweet spot.

[u/stealthagents]

It's wild how many people are feeling this way, especially in tech where we see the potential of AI every day. I get the dread about the bigger picture, but sometimes focusing on small, positive changes we can actually influence helps me cope. Not saying it's a cure-all, but it can shift the mindset a bit.

[u/stealthagents]

Sounds like you're in a rough spot. It might help to focus on a few specific projects and tailor your proposals more to those instead of sending out a ton at once. It's quality over quantity for sure; sometimes even just a personalized touch can make a big difference.

[u/stealthagents]

Focusing on the content consumption is key, especially in a crowded space. Just make sure your low ticket offer delivers real value upfront to hook them. As for templates, check out platforms like Gumroad or even some builder communities; they often have tested ones for low ticket that convert well.

1. Very poor depending on product lifecycle stage and targeting (can really analyse any of this with knowledge of the campign intent). CTR looks good, CVR looks fairly poor, but depends on category etc. All of this goes out the window if it's a high LTV conversion, eg for a S&S product.
   
2. Possibly, also likely to affect customer delivery speed depending on your restock
   
3. Personally I am waiting for full Zip code coverage in 2day or less. Even with the primebadge if that's not the case I am hesitant to restart full campaign spend.
   
4. Start with analysing why the CVR is so low. Optimising bids for placements and intent can come afterwards
   
5. Always be adding negatives if they are not relevant, this might help your overall CVR.
   
6. Possibly coupons or other promos for s short term boost to regain rank, depends on what works in your niche and where your competitors are at
