Five tests you run with your own hands on your own store. You record the result, the page keeps score.
Protocol
Run them in order on your store and record the result. Nothing is sent or stored, the counter lives only in this browser tab.
2 min
What to do
What should happen
The same number of payment methods in both currencies.
What it means if it doesn't
The payment gateway is restricted to one currency and simply drops off the list under euro. A foreign customer sees a bank transfer and nothing else, so they do not pay. No uptime monitor will show this, because every page still returns a 200.
2 min
What to do
What should happen
The same figure three times, or a difference exactly equal to the shipping cost.
What it means if it doesn't
One counter works net, another gross, and a third omits VAT on shipping. The customer sees three different prices for the same order and stops trusting you at the exact moment they were about to type a card number.

What to do
What should happen
Clarity does not load, and any cookieless Google Analytics request carries the denied analytics_storage state. The request alone does not mean an analytics cookie was stored.
What it means if it doesn't
Clarity still loads after refusal, or Google Analytics receives permission for analytics storage. Check the analytics category in your consent-management configuration.
2 min
What to do
What should happen
A comparable number of results all three times, with a product from that category at the top every time.
What it means if it doesn't
The search matches a string, not a meaning. A customer who types the category in the plural gets nothing or an unrelated assortment, and leaves convinced you do not stock the thing sitting in your warehouse.
3 min
What to do
What should happen
The whole body in the chosen language, including the withdrawal form and the carrier names at checkout.
What it means if it doesn't
The headings and the menu are translated and the documents underneath are not. A foreign customer gets a local-language return form in an English store, and that document is the one that legally binds them.
Honestly
Five tests are five tests. Here is what turns up in audits regularly and cannot be checked in ten minutes without access to the store.
What next
Crawls the whole site and shows which pages return an error today, what is missing from the sitemap and what robots.txt blocks. It answers whether the pages open.
Run the free auditA manual walkthrough in four language and currency combinations, from the homepage to the payment screen. It answers whether anyone can pay on those pages. Every finding carries evidence and an address.
