What are some things you should know when promoting your product overseas?

Promoting a product overseas has some very different aspects than promoting it domestically.
If you don't know the specific points to be aware of when promoting to overseas markets, your promotion may end up having the opposite effect.
First, we will briefly explain the points you need to know when promoting your product overseas .
Video sites are recommended for promoting your products overseas
The first thing to consider is how you will promote your product.
To sum up, we recommend making use of video sites and social media such as YouTube , Instagram , and TikTok .
Currently, consumer behavior overseas is undergoing major changes.
The percentage of people who gather information from videos before purchasing a product is increasing year by year overseas as well.
Do you gather information on video sites before making a purchase?
The same goes for overseas consumers.
In particular, the amount of time spent watching product introduction videos on YouTube has increased dramatically in every country.
In the United States, data shows that over 70% of consumers watch related videos on YouTube before purchasing a product.
A similar trend is seen in European countries, where video content has become essential for promoting products overseas.
Videos can promote your products more effectively
The expressive power that only videos can offer is another reason why we recommend YouTube, Instagram, and TikTok for promoting your products overseas.
Videos can convey more information more effectively than text or photos alone.
By using a combination of video and audio, you can help consumers understand at a glance how to use your product.
Another advantage of video is that it allows you to add narration in foreign languages , including English.
You can easily add narration to your videos by creating it on a text-to-speech site that uses the latest AI.
You might think, "Wouldn't it be enough to just add subtitles in a foreign language?" However, if the narration remains in the original language, viewers may quickly close the video .
International customers are looking for narrated videos in their own language to learn more about products.
By using an AI text-to-speech site , you can create narration in not only English, but also languages from around the world, including French, German, Spanish, Chinese, and Korean, allowing you to provide detailed support to users all over the world.
What are the key points to successful overseas product promotion?
Companies that are successful in promoting their products overseas have several things in common.
First, don't compromise on the quality of your overseas promotional videos.
When creating promotional videos for overseas audiences, it is essential to tailor them to suit overseas viewers .
One of these is narration with native pronunciation .
By utilizing a high-quality AI reading service , you can accurately communicate the strengths of your product in foreign languages such as English.
Of course, it is also important to continue promoting .
Overseas promotional videos for products are not something that can be created once and then finished; they need to be continually improved by analyzing viewer reactions.
By regularly updating your video channel and social media accounts , you can more effectively communicate your appeal and increase the number of fans of your product or brand.
It is also very important to have a deep understanding of local needs .
When promoting your products overseas, it is important to have a deep understanding of the trends and consumer behavior specific to your target market.
Even if you are unable to conduct direct surveys in the area, you can accurately understand consumer psychology by referring to video comments and reactions on social media , or by checking videos that are popular with local consumers .
When promoting a product overseas, it is important to use a method that is different from that used domestically and is tailored to suit overseas consumers.
We recommend that you start by creating a promotional video with narration in native pronunciation.
YouTube is recommended for promoting your products overseas
There are several video sites and social media platforms for promoting products overseas, including YouTube, Instagram, and TikTok.
If you are just starting to promote overseas, we recommend starting with YouTube .
YouTube is used in over 190 countries and has over 2 billion monthly users.
Having a large number of users is the biggest advantage when promoting a product overseas.
Looking at YouTube usage in each country, the demand for video content is steadily increasing.
Of course, the number of viewers of product promotional videos is increasing every year .
Product promotional videos on YouTube tend to rank highly in search engines, and you can also expect natural inflows from overseas through Google searches and other means.
YouTube also has a subtitle function, so by combining it with narration using AI reading, you can reach more overseas users.
Differences between videos for overseas and domestic markets
Videos that are popular overseas have characteristics that are significantly different from those for the domestic market.
First, the length of the video.
Preferences for video length vary by country.
In the US, videos of around 2-3 minutes tend to be preferred, while in Europe, videos that are a little longer tend to be preferred.
It is also important to adapt your expression to cultural differences .
In Japan, understated language is preferred, but in America, language that more directly conveys the superiority of a product is more effective.
When promoting a product overseas, the choice of colors and music must be carefully considered to suit the target audience.
Also, when adding English narration, it is important to adjust the tone of the reading to suit the target region .
AI reading services can read in a wide variety of voices, so it is possible to create different versions, such as American English for the US market and British English for the UK market .
[Free] If you want to create a promotional video for your product overseas, we recommend "Ondoku"

[Practical Edition] Let's make an English promotional video with "Ondoku"

Now, let's take a step-by-step look at how to create a promotional video for your product overseas using the AI text-to-speech service "Ondoku."
1. Prepare a script in a foreign language
First, prepare a script in a foreign language such as English .
The key is to use simple, clear words and sentences that are easy for overseas customers to understand .
If you write your sentences with the aim of conveying the product's features in 30 seconds , you can write something concise and memorable.
We recommend using an AI translation service to create scripts.

Don't worry, you can use AI translation in such cases!
- English
- French
- German
- Spanish
When translating into foreign languages commonly used in the United States and Europe, such as these, we recommend the AI translation service "DeepL."
AI translation services have very high translation capabilities, so they can create sentences using phrases that will increase purchasing desire and maximize the effectiveness of your product's overseas promotion.
There are also AI translation services that specialize in specific languages , such as Baidu Translate for Chinese and Papago for Korean, so depending on the language, you might want to consider using services other than DeepL.
We also recommend using generative AI services such as "ChatGPT" and "Claude."
Just give instructions such as "Please translate the following sentence," and it will generate accurate sentences tailored to each language and foreign culture.
For tips on translating scripts for videos aimed at overseas audiences, please check out this article!
Check the translated text by back-translating it
However, when using an AI translation service, it is also important to check the translation results .
Once you have translated a sentence, be sure to translate it back into the original language to check for any errors.
If you use a generative AI service like ChatGPT or Claude, we recommend checking the results by inputting them into another service like DeepL or Google Translate.
"Telling a story": Key points when writing a video script for overseas markets
When writing a script for a product promotional video for overseas audiences, it is important to keep in mind that it should convey a "story" related to the product .
The story behind your product is called your "brand story."
There are two things we would like to convey in our promotional video for overseas audiences.
- Functional value of the product
- The emotional value of the product
is.
What is particularly important is the "emotional value of the product."
- How the product has been loved in its home country
- How was the product created?
- Who designed the product?
- Who makes the product?
By conveying such a "story," we can make overseas users feel that "I want that product!" rather than any other product .
Rather than just creating an overseas promotional video, we recommend giving your product a "story" in order to actually increase sales.
2. Generate voice with Ondoku
Once the script is complete, enter it into Ondoku to create the narration.
Using "Ondoku" is very easy.
Once you open the top page, select the script language, such as English.
All you have to do is paste the script text and it will be read aloud.
Utilizing the wide variety of voices in "Ondoku"
Ondoku allows you to choose from a wide variety of voices, including male and female, in any language.
You can listen to voices in various languages from this page, so we recommend listening to them and then choosing the voice that best suits your product.
[Ondoku] Listen to the voices and sample audio for supported languages | Text-to-Speech Software Ondoku
Here we will introduce Ondoku's supported languages and sample audio.
Product promotional videos are often narrated by a female voice, but male voices are also ideal for luxury products such as cars and watches.
You can also alternate between female and male voices to add variety to your video content.
With "Ondoku," you can also change the reading speed and pitch of the voice .
Generally, you can leave the settings as they are, but it is recommended that you read important product information a little more slowly.
Once the settings are complete, generate the narration audio.
Once you've finished setting it up, press the "Read aloud" button to generate the audio.
The audio will be generated immediately , so just keep the screen open and wait.
Once generation is complete, the display will change and playback will begin automatically .
Listen to the generated audio and if you're happy with it, download the audio file.
The audio file for "Ondoku" is available for download in MP3 format .
3. Editing product promotional videos for overseas markets
Once the narration audio is complete, we will combine it with the video footage and edit it into a product promotional video for overseas markets .
When editing a video, the key is to arrange the video and audio so that the video has a good tempo.
The first 15 seconds of your YouTube video determine whether or not someone will watch it.
Don't hold back on information, and make sure to create a video that grabs the viewer's attention in the first 15 seconds.
It is recommended to refer not only to videos that companies use to promote their products overseas, but also to videos by popular YouTubers .
It is also a good idea to add subtitles to your videos.
Nowadays, YouTube videos usually have full subtitles.
You can write your own subtitles based on the script text, but this is very time-consuming.
In such cases, you can use an AI service to automatically generate subtitles in the "SRT file" format .
Please take a look at this article, which explains how to add subtitles to a video from an SRT file using the AI transcription service "Transcription-san."
We recommend loading the subtitle SRT file into YouTube's subtitle function as well as the subtitles in the video.
Even if you can only create videos in English due to time or budget constraints, you can use YouTube's automatic translation feature to generate subtitles in other foreign languages based on English.
For European languages such as French, German, and Spanish, translating from English rather than Japanese is more accurate, so it is recommended that you load the SRT file with English subtitles onto YouTube.

In this way, by using the AI reading service "Ondoku," you can very easily create product promotional videos for overseas audiences.

Things to keep in mind when posting product promotional videos for overseas markets
There are also a few points to keep in mind when posting product promotional videos for overseas audiences on video sites such as YouTube.
The posting time is also important for videos aimed at overseas audiences
When posting a product promotional video for overseas audiences, it is important to use the scheduled publishing function to publish the video at a time when it is most likely to attract viewers .
By setting posting times to suit the audience in each country, you can maximize the effectiveness of your product promotion overseas.
If you have social media accounts , you can also help spread the videos you post on YouTube by promoting them a few minutes after posting .
As a technique for spreading your content on social media, we recommend cutting out a section of a video you posted on YouTube and posting it on Twitter, Instagram, TikTok, etc.
Important points to remember when shooting and editing
When creating a product promotional video for overseas markets, it is important to structure it so that the audio can be replaced later .
Edit the footage so that it doesn't sound out of place even if you use the same footage and just replace the narration audio with another language .
Even if the script has the same content, the length of sentences will vary depending on the language.
When editing a video, it's a good idea to leave some leeway in the length of each cut, as long as it doesn't disrupt the overall tempo.
It's also important to analyze videos of competing products
Just like with other methods of promotion, analyzing competing products is extremely important when promoting overseas through video.
Let's check out what kind of overseas promotions competitors are running.
If you already have a product that is popular overseas, the key is to understand what kind of English expressions and reading aloud styles are preferred.
When analyzing competitors' videos, pay attention to audio quality and reading speed.
Search for similar products on YouTube and analyze trends in the narration used in popular videos.
Narration audio preferences vary by country and language, so you can promote your product overseas more accurately.
