76% of online consumers prefer buying from sites in their own language. Yet most e-commerce businesses attempting international expansion simply translate product pages, completely ignoring video marketing.
It’s a costly mistake. Product videos increase conversions by 80% on average. But a video in a foreign language? It reduces that effectiveness by 60%. The solution is dubbing, and in 2026 AI has made it accessible even to small merchants.
Info
Important: product videos increase conversions by 80%, but only if they’re in the customer’s language. A non-localized video loses 60% of its effectiveness in foreign markets.
💰 Why Videos Are Crucial for International E-commerce
The numbers speak clearly:
- 88% of consumers watch product videos before purchasing
- 73% are more likely to buy after watching a video
- 64% of customers buy online after seeing brand social videos
- Videos in local language: +40% time on page, +25% conversions
For an e-commerce selling in multiple countries, every percentage point of conversion counts. On $100,000/month revenue, a 5% conversion increase means $5,000 more. Every month.
🎯 Which E-commerce Videos to Dub
Not all videos have the same impact. Here’s the priority:
1. Product Videos (Maximum ROI)
Videos showing the product in action. Demonstrating use, quality, details.
Why dub: The voiceover explains features that images can’t convey. “This fabric is water-resistant” has more impact when said in the customer’s language.
Where to use: Product pages, Amazon Listings, landing pages
2. Tutorial/How-To Videos
How to use the product, installation, maintenance.
Why dub: They reduce returns and support requests. A customer who understands how to use the product is a satisfied customer.
Where to use: Support page, post-purchase emails, YouTube
3. Brand/About Us Videos
Who you are, your story, your values.
Why dub: They build trust. Foreign customers are more skeptical - a story told in their language creates connection.
Where to use: Homepage, “About Us” page, brand awareness campaigns
4. Testimonial Videos
Customer reviews in video format.
Why dub: More complex (need subtitles or dubbing of original speech), but very effective for social proof.
Where to use: Landing pages, retargeting ads
Tip

💡 How to Implement a Localized Video Strategy
Phase 1: Audit Existing Videos
List all videos you have:
- Product videos
- Brand videos
- Tutorial videos
- Social videos
- Ad videos
For each, evaluate:
- Duration
- Importance (how much it impacts sales)
- Original audio quality
Phase 2: Prioritize by Market and Product
Priority formula:
Priority = (Product revenue) × (Market potential) × (Video type impact)
Example:
- Product A generates $55K/year, Germany expansion (high potential), product video (high impact) → HIGH PRIORITY
- Product Z generates $2K/year, Poland expansion (medium potential), social video (medium impact) → LOW PRIORITY
Phase 3: Dub in Batches
Use NovaDub to dub efficiently:
- Upload all priority videos
- Select target languages (start with 2-3)
- Process in batch
- Download and organize by market
Cost example - E-commerce Catalog:
- 30 product videos × 2 minutes average × 2 languages = 120 minutes
- With NovaDub Pro: ~$200
Phase 4: Distribute Strategically
Product pages: Replace or add localized version
Amazon/Marketplace: Each local listing should have video in local language
Ads: Create separate campaigns per market with dubbed videos
Social: Post on local channels (if you have them) or use geographic targeting
Phase 5: Measure and Optimize
KPIs to track:
- Conversion rate per country (pre/post localized videos)
- Time on product page
- Bounce rate per market
- Revenue per market
Warning
Warning: don’t just dub. Make sure the entire customer journey is localized: site, checkout, emails, support. Videos are one piece of the puzzle.
