With these foundations in place, here is a three-steps strategy to protect your margin while building international sales.

1. Offer a localised experience on many markets as possible, where you can ship legally and handle taxes and returns

Create localised sites through Shopify market, Glopal or any other site localisation provider and leave the sites open to SEO with correct hreflang tags to be crawled by Google in the right country for a month or two to collect first data. Then review the markets showing the biggest amount of engaged sessions.

Why is it important to open even small markets? Localised sites for smaller markets cost little to keep open, and they can generate sales with no advertising at all. In the accounts I manage, sites opened in 10 to 20 small markets such as Slovenia, Slovakia, Cyprus, Malta, Morocco or Algeria, with no campaign to support them, have represented between 10% and 30% of international revenue after about a year of building site authority. Each market is small, but together they add up.

2. Test Markets Using Lower-Funnel Campaigns

Avoid launching large awareness campaigns with custom creatives immediately.

Instead, begin by testing demand with lower-funnel campaigns that target customers already searching for products like yours in your top 5 markets based on first organic data collected from these international localised sites.

I recommend running Google Shopping campaigns through Google Ads in each tested market with a very small daily budget. You will need to create a shopping feed for each of these markets beforehand.

After approximately one to two months of collecting traffic data, review which countries are generating the highest volume of conversions to a decent ROAS/CPA.

Paid campaigns can also speed up the organic growth of these new sites.

3. Scale Based on Profitability, Not Revenue

Once a market consistently achieves your target ROAS, gradually expand your investment by introducing different campaign types or channels such as Performance Max campaigns or Meta. These campaigns reach additional customers outside the search result page, while learning from the conversion data and customer lists built by earlier campaigns.

For underperforming markets, either continue testing with a limited budget or pause investment and redirect spend toward countries showing stronger potential.

The key is to earn the right to scale. Invest in upper-funnel activity only after lower-funnel campaigns consistently generate profitable returns for a significant volume of conversions.

One of the biggest mistakes brands make is spreading your ad budget across too many countries at once.

International growth should be driven by profitability, not simply sales volume.

Concentrate your advertising budget on markets that consistently deliver:

• Strong ROAS
• Healthy profit margins
• Sustainable customer acquisition costs
• Growing demand

Once these markets become stable, use their profitability to fund expansion into new countries.

This disciplined approach allows you to grow internationally while protecting your margins and avoiding unnecessary risk.

Final Thoughts

International expansion is about much more than translating a website or launching campaigns in new countries. Success comes from combining localisation, reliable measurement, efficient logistics, and disciplined advertising investment.

With the right strategy, you can identify high-potential markets, allocate budget more effectively, and scale internationally while maintaining a profitable Return on Ad Spend.
