Place a real order on your own phone before you touch anything
Start with the cheapest check there is. Open your store on your own phone, on mobile data rather than office wifi, and buy something small paying by KNET. Not a test order from the admin panel, a real one with a real card. Then repeat it on an iPhone and an Android, and once from inside the Instagram in-app browser, which is where most of your traffic actually sits. You are looking for a gateway that times out, a shipping rate that fails on a Jahra address, or a coupon field that throws an error. Do this today. If checkout is broken you are losing every sale, not some of them.
Then look at one number: conversion rate, sessions to orders. Most Kuwait stores run between 1% and 2.5%. If yours fell from 1.8% to under 0.8% inside a week while traffic held steady, the problem is on the site, not in the market. Check the mobile figure on its own, because 80% to 90% of your sessions are phones and a theme edit that looks fine on desktop can be a disaster on a small screen. Check page speed too: over four seconds on mobile data and you lose roughly a quarter of people before they ever see a product.
If your checkout is a WhatsApp number, a manual bank transfer, or a plugin somebody bolted on two years ago, this failure will keep repeating. A store running on Shopify with a KNET gateway gives you a checkout you can actually debug, abandoned-cart data, and an order log that shows exactly where people stop. Whatever you use, keep a written weekly checkout test: five minutes, done on a phone, by a person. Almost every silent revenue drop we get called about in Kuwait had been live for eleven to twenty days before anyone placed an order themselves.

Tracking breaks before the market does
Second check, still free. Open your store's own order count for the last 14 days and put it next to the purchases your ad platform reports. If the store shows 180 orders and Meta claims 60, your sales did not drop, your reporting did. That gap widens after every iOS update, every theme edit that drops the pixel, and every time a developer touches the code. A gap under 20% is normal attribution noise and you leave it alone. A gap over 40% that appeared suddenly means the pixel or the Conversions API is broken, and you fix that before you change a single ad.
Third check: creative fatigue. Pull frequency for your main ad set over the last seven days. Under 2 is healthy, 2 to 3 is tiring, and over 3.5 in a market of four and a half million people means everybody has already seen it. Fatigue has a specific shape: CPM climbing 30% or more, click-through roughly halving, cost per purchase doubling, while the conversion rate on the site stays flat. That last part is the tell, because it separates a tired ad from a broken store. Snapchat and TikTok burn creative faster than Instagram here, so plan a new hook every two to three weeks.
Do not judge any of this on one day. Kuwait sells on a Thursday-night-to-Saturday rhythm, and one quiet Wednesday means nothing at all. Give a new creative 3 to 5 days or roughly 50 link clicks per ad before you call it, and read the account on a rolling 7-day window against the 7 days before it. If you kill ads that are one day old you will spend the whole month restarting the learning phase, your costs will stay high for reasons you created, and you still will not know what actually broke.
Stock, the calendar, and the competitor you have not checked
Fourth check, and this one embarrasses people: is your best-seller out of stock? In most Kuwait stores one or two products carry 30% to 50% of revenue. When that product hits zero, total sales fall by roughly its share while the ads keep spending, because the ad account has no idea. Sort your products by revenue for last month and check the stock level on the top five. Set a low-stock alert at whatever ten days of sales looks like for you. Check variants too, because a hero product missing its two most-sold sizes reads as available and converts like it is not.
Fifth: the calendar. Compare with the same weeks last year, never with last month. Kuwait's year is lumpy. July and August empty out as families travel and most stores lose 20% to 40%. The last ten days of Ramadan and the week before Eid are the strongest stretch of the year, and the week straight after Eid is the deadest. Back-to-school lifts September. Hala February and National Day help fashion and gifting and not much else. If this year's week is within 15% of the same week last year, nothing broke, you are simply looking at your own season.
Sixth, last, and the only one that takes real work: somebody changed the price. Buy from your two nearest competitors once a quarter and check their landed price, their delivery fee, whether they now offer Tabby, and how fast they actually deliver. A new entrant undercutting you by 15% shows up as a falling conversion rate on unchanged traffic, which is exactly what a broken checkout looks like, so rule out the cheap causes first. Then give any pricing or positioning response a full 14 days before you judge it. Panic discounting inside one slow week costs more than the slow week did.
