How to research a niche across countries
A niche that is crowded in one country can be wide open in another. Here is a step by step method for comparing stores, traffic, ads, prices and shipping across markets before you expand.

Most store owners research a niche in their own country and stop there. That leaves a lot on the table. A product type that every second store sells in the United States may have only a handful of serious sellers in Germany, Australia or the Gulf. The reverse also happens, where a niche that looks open at home is already crowded in the country you were planning to expand into. This guide shows how to compare one niche across several countries using public data, so you can decide where to launch or expand.
Key takeaways
- Compare the same niche in several countries using the same checks, so the results are comparable.
- Count active stores, read their traffic estimates and look at ad activity in each region.
- Currency, language, shipping promises and payment methods show which country a store really serves.
- Ad libraries differ by region. EU ads show reach data that other regions do not.
- Look for gaps, such as demand with weak local stores, rather than the biggest market.
Step 1. Define the niche tightly
"Pet products" is a category. "Calming beds for anxious dogs" is a niche. A tight definition makes every later step clearer. Write down:
- the core products, with two or three keywords for each
- the price range you expect to sell at
- who buys it
Step 2. List candidate countries
Start with three to six countries you could realistically serve. Think about language, shipping, payment methods and returns. A niche in a country you cannot deliver to in a reasonable time is not an opportunity.
Step 3. Count and size the stores in each country
With RivalSonar
In the Store explorer, filter by category or keyword, then by country. Note how many stores appear and sort by estimated revenue or estimated monthly visits. Open the top few profiles to see their best sellers, traffic and ads. Each search costs 1 credit per result row, so narrow your filters before you widen the result count.
By hand
Search the niche keywords on a local version of a search engine, such as the country domain or with the country set in settings. Note which stores appear, then check where they ship from and to.
What to record
For each country, record:
| Measure | Why it matters |
|---|---|
| Number of active stores | A rough measure of competition |
| Estimated monthly visits of the top three | How much demand the leaders capture |
| Spread between leader and fifth store | A big gap means a dominant player |
| Share of stores that are local | Local stores usually win on shipping and trust |
Remember that visit and revenue figures are estimates. RivalSonar models monthly visits from public traffic rankings and derives orders and revenue from them. Use them to compare stores and countries against each other, not as exact figures.
Step 4. Check where the traffic comes from
Countries
A store's traffic by country tells you whether it is really serving the market you are looking at. A store based in one country can draw most of its visits from another. In RivalSonar's Traffic research you can see estimated monthly visits, the top countries and the main traffic sources for any store.
Sources
Compare how the leaders in each country get visitors.
- Mostly paid social suggests the niche is driven by ads and impulse buys.
- Strong organic search suggests people already look for the product, which is a good sign for long-term demand.
- A lot of direct traffic suggests a known brand with repeat customers.
A country where the leaders rely only on paid social is often easier to enter than one where an established brand owns organic search.
Step 5. Read the ads in each region
Use region filters
Ad libraries let you filter by country. Run the same keywords in each country and note how many advertisers are active, how long their ads have run and what angles they use. RivalSonar's Ad library covers Meta, TikTok, Pinterest and Snapchat, with reach, spend estimate, active days and an AI score that marks ads as testing, scaling or winning.
Know the regional differences
Ads that run in the European Union carry more public data because of EU transparency rules. The Meta Ad Library shows EU reach for those ads, which gives you a direct read on how many people saw them. Outside the EU, you usually have less detail, so lean more on how long an ad has run. The ad longevity guide covers how to read this.
Compare angles
The same product is often sold differently in different countries. A gadget sold on convenience in one market may be sold on safety or savings in another. Note the main angle in each country. A country where nobody uses the angle that works best elsewhere is worth a closer look.
Step 6. Read the local signals on each store
Open the top stores in each country and note:
- Currency. Does the store price in the local currency, or only in a foreign one?
- Language. Is the site translated well, machine translated or not translated at all?
- Shipping promise. Local delivery in a few days beats international delivery in two weeks.
- Payment methods. In some markets local methods or cash on delivery are expected, and a store without them loses buyers.
- Price level. Compare the price of the same or similar product across countries. A big gap can mean room for a cheaper entrant, or a market that accepts higher prices.
Stores that serve a country poorly on these points are a sign of an opening.
Step 7. Score each country
Put your findings in one table and score each country from 1 to 5 on these points:
| Factor | What a high score means |
|---|---|
| Demand | Strong traffic estimates and lasting ads |
| Competition | Few strong local stores |
| Local fit | Leaders are weak on currency, language or shipping |
| Ad cost and reach | Ads are reaching people without many advertisers |
| Your ability to serve | You can ship, support and take payment well |
Add the scores. The best country is rarely the biggest. It is the one where demand is clear and the existing stores leave a gap you can fill.
Step 8. Validate before you commit
Before you build a localised store, test the niche in the chosen country with a small ad budget pointed at a well-prepared product page. Run the product through the product validation checklist first, using the local price, shipping and margin.
Keeping an eye on the market
Once you pick a country, save your search in RivalSonar and turn on the daily digest so new stores in that niche and country reach your inbox. Track the two or three local leaders in the Sales tracker to see which products they push and when, as described in how to track competitor sales daily.
All traffic, order and revenue figures in RivalSonar are estimates from public sources, such as public traffic rankings, public storefront pages and public ad libraries.
