How do I optimize a Google Shopping feed when I am selling across multiple countries?

You do not need a second Merchant Center account for a second country. One account serves multiple countries fine, and opening extra accounts is how people get themselves into trouble. What each country does need is its own feed, set up in your feed app with the correct language, currency, and channel targeting. One channel for Germany in EUR and German, one for the UK in GBP and English, each syncing to its own Merchant Center target country.

When a market goes quiet for no obvious reason, this is where to look first. A feed pointed at the wrong target country is the classic cause. Check the channel settings in your feed tool and confirm the right feed is linked to the right country.

This is the part people skip. A title is a keyword match, so a translated title only works if it contains the words that market actually searches. A German shopper does not type the English phrase, and the direct translation of your best English keyword is often not the phrase Germans use for that product.

So do not machine-dump your titles into five languages and call it a multi-country feed. Each market needs its own converting search terms pulled from its own data, then its own title built around them. Same structure, different words. Getting the grammar right is the easy half. Getting the actual search phrase right is the half that earns.

ZenoX optimizes feeds per market for exactly this reason, and we build each one from that market's real search terms rather than translating the winner from the home market and hoping.

Give each country its own campaign so the algorithm learns each market separately. Traffic patterns, competition, and conversion rates differ by country, and mixing them in one campaign muddies the signal for all of them. Two campaigns only fight each other if they target the same products in the same country, so a clean split by market keeps them out of each other's way.

Then sequence them. Launch the home market, get it profitable and stable, then open new countries one at a time as deliberate steps. Each new market is essentially a new account starting from zero: its own budget, its own data, its own learning window. Opening everywhere at once splits the budget and splits the data, and then no market gets enough of either to work.

ZenoX runs this order even when a client is impatient. We add markets one at a time so any country-specific problem shows up cleanly instead of hiding inside four other launches.
