International PPC: Pay-Per-Click Guide for Small Businesses

Expanding into a new country with international ads can be an exciting way to open up new growth opportunities. But it’s not uncommon for the most successful PPC campaigns in your home country to underperform in a new one. The cost per click might climb, impressions may dip, and products that usually convert well may suddenly stall. 

International PPC isn’t just about turning on ads in multiple countries. It’s about understanding how customer expectations shift once you leave your home market, then adapting your marketing efforts so those new regions become real profit centers.

I’m the CEO of Flywheel, a digital ad agency. My team and I have managed millions in ad spend across dozens of countries. Now, I’m sharing how successful international PPC campaigns work, what sets them apart from domestic campaigns, and how to build ads that perform reliably in new international markets.

What is an international PPC campaign? 

Pay-per-click (PPC) refers to a performance-based advertising model where you’re charged when a user engages with your ad, typically by clicking. While auction-based ads can charge per click, impression, or conversion, “PPC” stuck as the catch-all term, because pay-per-click auctions popularized the format.

Search engines like Google, as well as platforms like Meta and TikTok, use an auction system to determine when your ad appears, who sees it, and how much you pay per click. For example, if two brands have the same target audience, the one with a higher bid and more relevant ad content is more likely to win the placement.

International PPC ads apply the same mechanics to audiences outside your home country—just not the exact same ad campaign. Instead of advertising only in your primary market like the United States, you target shoppers in regions like Canada, the UK, Australia, India, or Japan. Depending on the platform, you can run a single campaign to a global audience or set up separate PPC advertising campaigns for each country.

Domestic vs. international PPC: Key differences 

Running global PPC campaigns isn’t just a matter of translating your ad copy. It often means rethinking how your campaigns work altogether. Here are three key differences that can shape your strategy:

• Brand familiarity. In your home market, people often already know your brand, which supports stronger click-through rates (CTR) and more predictable conversions. In new countries, that familiarity disappears, resulting in initially lower conversion rates while you build brand awareness from the ground up.

• Ad costs. Competition levels and local currency strength directly impact the CPC in each market. The US tends to have the highest cost per thousand impressions (CPM), or the cost to reach 1,000 people. Markets like Canada, India, Australia, and Japan are often more affordable.

• Regulations. Each region has its own data and privacy requirements you must navigate before launching campaigns. For example, GDPR compliance in Europe requires stricter data and privacy compliance for all PPC ads.

This combination of advantages and disadvantages can make it hard to estimate your ad spend or customer acquisition cost (CAC) in a new region. It might be lower or higher, but it’s almost always different.

How to build successful international PPC campaigns

1. Set a clear market goal
2. Localize your online store
3. Set performance expectations
4. Plan where to target customers
5. Refine your targeting
6. Segmenting your reporting

When running international PPC campaigns, I follow a reliable sequence: First, verify the business is ready to sell in the target country, then set performance expectations, and then design the international campaigns. Only after that should you start spending. Here’s the process I use with Shopify businesses expanding into new markets:

1. Set a clear market goal

Start by getting a sense of what success looks like in the new region. The most common way is to set a target timeline to achieve a profitable customer acquisition cost. 

Start defining your breakeven CAC and target return on ad spend (ROAS), which helps you understand how profitable each international campaign is. Then determine how long you can operate while sustaining a loss before hitting that number. This can range from one month to two years.

2. Localize your online store

A strong campaign can get clicks, but if your site feels foreign to the market you’re reaching, those international shoppers won’t convert. A localization strategy adapts your website to feel familiar to a local audience, and this often is the make-or-break step in international PPC. This includes translating your content, pricing in local currency, offering region-specific payment methods, and updating product imagery or messaging to align with cultural norms.

For example, showing prices in the shopper’s local currency alone reduces friction. In fact, 49% of US and UK consumers say they would abandon a purchase if they can’t use their local payment option. 

Shopify Markets is a built-in tool for managing PPC campaigns, international sales, retail, and business-to-business (B2B) expansion. It lets you adjust pricing strategies, currencies, languages, domains, and product catalogs for different regions. Shopify Markets include multicurrency and multilanguage experiences out of the box, so shoppers see the correct version of your store based on their location.

Automated translations (via a tool like Google Translate) are a good starting point, but in my experience, performance improves when you have a native speaker also review the ad copy. Consider professional translation an investment in improving your conversion rate.

3. Set your performance expectations

Before launching into a new market, I don’t just note what’s different in the target market; I decide how those differences should change my expectations. The goal is to establish a realistic baseline so early results don’t get misdiagnosed as site or channel issues. I look at four variables:

• Brand awareness. Start by estimating how familiar the market is with your brand and set conversion expectations accordingly. If you’re entering a market with strong cultural crossover and the same language—like the US to Canada—some shoppers may already know you. In markets where you’re less visible, assume shoppers don’t know your brand. Plan for meaningfully lower conversion rates until you build familiarity.

• Shipping and fulfillment. Set conversion expectations based on the shipping experience. Longer delivery times, higher costs, import duties, or unclear fees all affect conversion. Expensive or slow shipping hurts performance, while clear expectations or subsidized shipping can improve it.

• CPMs. Assume that the cost to reach your target audience will be different from your home market. Some countries have a lower cost per click, letting you generate more traffic for the same budget, while others may be more expensive. Check estimated CPMs using tools like Google Keyword Planner or Meta’s Ads Manager, and base your budget and performance expectations on these regional differences—not your domestic benchmarks.

• Regulations. Factor regulatory and platform limitations directly into your success criteria. For example, Europe’s GDPR compliance requirements limit how platforms collect and use personal data, which shrinks attribution and audience size. Meta’s paid, ad-free subscription (rolling out in Europe and the UK) also means fewer ad impressions for advertisers.

This exercise keeps you grounded when early results differ from home-country performance. I often remind clients: Your site isn’t breaking. Your audience is different.

4. Plan where to target customers

International PPC isn’t about using every platform. It’s about choosing marketing channels that match your products and how people shop in each region. Here are the three top channels for international PPC:

• Meta. Great for prospecting and remarketing due to Meta’s powerful targeting tools. Works well for visual-focused brands like skin care, apparel, and home goods.

• Google. When expanding internationally, Google search ads and Performance Max help you reach shoppers who are already comparing options or ready to buy. They tap into the demand that already exists in that market.

• TikTok. Useful for younger markets or regions with high TikTok adoption, like the US and Southeast Asia, helping them quickly understand how a product fits into their lives.

Self-explanatory products like apparel can direct visitors to a homepage or collection page. Products requiring explanation, like skin care routines or supplements, perform better when each ad and landing page is designed to provide key details and social proof.

By sending both Meta prospecting ads and Google ad campaigns directly to these landing pages instead of the homepage, new international customers get the information they need without navigation friction. This builds trust faster than sending them to pages that assume brand familiarity.

5. Refine your targeting

Ad targeting settings matter in every campaign, but they’re especially critical in international markets, where it’s easy to show ads to the wrong group without realizing it. In markets like Thailand or Japan, interest-based location targeting can inadvertently attract tourists or researchers rather than genuine local customers, which is what we want to avoid. I always double-check whether I’m targeting:

• People living in the location

• People interested in the location

• People who were recently in the location

Choosing the correct setting is a quiet PPC best practice that prevents major budget waste in different countries.

6. Segment your reporting 

Brand awareness, CPMs, shipping expectations, and buying power all vary by country. If you combine all regions into a single report, it can look like your domestic ads conversion rate suddenly dropped or your traffic quality declined. In reality, you’ve just introduced a new audience with different behavior.

At Flywheel, we break out results by country to see how each market is performing, whether a new region is affecting overall conversion, and which markets are worth scaling or testing further. Customer segmentation by country or region removes confusion and prevents you from making the wrong optimizations based on blended data.
