Why did Meta ROAS drop for an electronics store?
If you sell consumer electronics, a Meta ROAS drop often starts outside Meta. A rival cut the price of the same model, a new version made buyers wait, or a best seller ran short. Thin margins make each drop hurt more, so check prices, launches and stock first.

If you sell consumer electronics, a Meta ROAS drop often starts outside Meta. A rival cut the price of the same model, a new version made buyers wait, or your best seller ran short. Thin margins make each drop sting more. Check prices, launches and stock before you rewrite a single ad.
If you sell consumer electronics
Your shopper can usually find the exact model you advertise, by name and number, in several other shops. That turns your purchase rate into a price contest you only half control. If a big retailer trims the price of the headphones in your ad, the ad still earns the click. The purchase happens somewhere else, and Meta's ROAS takes the hit.
Launches do the same thing on a calendar. When a new phone, console or camera is announced, some buyers of the current model wait. Accessory buyers wait with them. Bigger tickets also take longer to decide. If a buyer researches for longer than your attribution window, the sale lands outside Meta's count, even when the ad did its job.
Margins decide how much any of this hurts. For illustration, at a 20% margin your break-even ROAS is 1 divided by 0.20, which is 5x. In the illustrative case, a slide from 6x to 4.5x crosses that line. At a 50% margin the illustrative line sits at 2x, and 4.5x clears it easily.
What one store's data shows
Store A is one store, and the export does not say what it sells. Read its journeys as one example of fast and slow buyers, not as data about electronics.
One store's anonymised GA4 export, 1 January 2024 to 21 August 2026. It holds shares of revenue only: no ad spend, no order counts.
| What the export shows | Value | Source cell |
|---|---|---|
| Share of revenue from journeys with 1 touch (0.5 days to buy) | 79.5% | Journeys sheet, 1 touch row |
| Share of revenue from journeys with 4 to 9 touches (16.9 days to buy) | 5.4% | Journeys sheet, 4 to 9 touches row |
| Share of revenue from journeys with 10 or more touches (16.0 days to buy) | 3.0% | Journeys sheet, 10+ touches row |
| Break-even ROAS at a 40% margin (1 / 0.40) | 2.5x | Break-even sheet, 40% margin row |
On the Journeys sheet, journeys with 1 touch hold 79.5% of revenue and took 0.5 days to buy. In an electronics store, that sounds like a shopper who already picked the model and only needs a fair price.
The long journeys hold less revenue but take far longer. Journeys of 4 to 9 touches took 16.9 days to buy on the Journeys sheet, and journeys of 10 or more took 16.0 days. If your laptop buyers behave like that, a sale that starts with a Meta click can close after a 7-day click window has shut. Meta's ROAS then dips while the sale still happens.
On the Break-even sheet, a 40% margin gives a break-even ROAS of 2.5x, because 1 divided by 0.40 is 2.5. That is arithmetic for any store with that margin, not a result from that store. If your margin on a television sits well below 40%, your line sits well above 2.5x.
The export cannot show Meta spend, orders or anything about electronics. It is one store, not a benchmark for your category.
What changes when you sell electronics?
Price checks. Note your price and the lowest price you can find for your top models each week. A drop that starts the day a rival's price falls is a price problem, not an ad problem.
Launch dates. Put announced launches on your calendar. A dip before a new model ships may reverse once it lands.
Returns. Shopify sends Meta the purchase when the buyer reaches the thank you page, valued at the order's total price. Its list of pixel events includes Purchase but no refund event. So a gadget sent back a fortnight later can still sit in Meta's purchase value. That flatters ROAS in a way your bank never sees.
What to do this week
- Check your top sellers. In Shopify, go to Analytics > Reports and open Total sales by product. Click the Compare to indicator and choose Comparison to past. Pass: sales fell evenly across models, which points at Meta or overall demand. Fail: sales fell on one or two models, so check rivals' prices and your stock for those first.
- Split purchases by timing. In Ads Manager, click the Columns: Performance dropdown and scroll down to Compare attribution settings. Pick 1-day click and 7-day click. Pass: both fell by a similar share, so timing is not the story. Fail: 7-day click fell much more, so slow buyers are drifting out of the window.
- Net out returns before you judge. In Shopify's sales reports, compare Sales reversals for the drop week with the week before. Pass: reversals stayed level, so returns did not move your numbers. Fail: they rose, so Meta's purchase value overstates what you kept, and the real drop is bigger than it looks.
Check the homework. Your GA4 Attribution paths export already holds the evidence. Causality Engine reads that one file and shows what each channel caused next to what last-click gave it, in 1 to 2 minutes, for €99 once (excluding VAT), refundable within 30 days. Check the homework

Frequently asked questions
Can a new model launch lower my Meta ROAS?
Yes, for a while. If buyers expect a new version, some wait, and accessory buyers wait with them. Your ads did not change, but your purchase rate did. Compare Shopify's Total sales by product for the weeks around the announcement before you change creative or targeting.Should an electronics store judge Meta on ROAS or profit?
On profit, when margins are thin. Purchase ROAS divides purchase value by spend and ignores what the goods cost you. Work out break-even ROAS as 1 divided by your margin, and judge Meta against that line rather than a round number someone liked.Why do my Meta sales fall when a rival runs a sale?
Because your ad still reaches the shopper, but the shopper buys where the price is lower. Meta only counts purchases that reach your site. If a rival undercuts you on the same model, your purchase rate drops while your ads, audience and budget stay exactly the same.
