The LINE app is a free messaging and social media application with an integrated payment system. It was developed in 2011 in Japan. Since its launch, it has become the most popular messaging app in Japan. Moreover, it is also widely spread in Taiwan, Indonesia, and Thailand. Thus many companies in Japan use LINE for their digital marketing campaigns. 

People know LINE for its free voice and text messaging services. In addition, it has plenty of innovative features, such as emojis, stickers, and games. The user can either download existing stickers or create them themselves. Another reason for LINE’s popularity is its focus on privacy and security. Users can hide their online status, and messages are encrypted to protect user data. Additionally, LINE has become a hub for entertainment, social and day-to-day activities. LINE allows companies to use their platform for digital marketing. This is not the case with many other messaging applications.

Afterward, users can buy them or download for free, and use them in their conversations. As a result, this builds brand awareness and appeals to a younger audience. To increase their reach, businesses can opt for sponsored stickers, which will appear in the “new” and “free” categories of the sticker shop.

    1. Advertising

    LINE Ads allows advertisers to access a variety of formats, targeting tools, and ad placement options across the Line family of services. Furthermore, LINE advertising also offers real-time campaign tracking and analysis. This provides companies with measurable results and insights.

      • number of video views
      • number of friends on your official LINE account


      In General, there are web ads, app ads, and video apps. Those ad formats are targeted to individual business goals. An advertiser should use web ads to promote content on an external website. But if the goal is to drive app downloads, an app ad is the right choice. However, a video ad is the correct choice to promote brand awareness.

      LINE App has eleven ad locations where an ad can be placed. It is important to note that a business can’t select the ad location when creating an ad.

      LINE advertising cost

      First of all, there is no minimum budget amount to advertise on the LINE app. To put it another way, a business can advertise according to its set budget. However, it is not possible to use Line Ads for free. After all, it is mandatory to buy 40 events per month. An event can be a click, a conversion, a view, etc. With this in mind, the monthly Ad budget is the cost per event multiplied by 40. A bidding process is used to determine the cost of an event. To understand the performance of a campaign, it should run for at least three months.

      To run LINE Ads, a company needs an Official Account. LINE charges according to the number of monthly messages included. The free plan includes 1,000 messages per month. It is not possible to exceed this number. The light plan contains 15,000 messages and costs 5,000 Yen, with additional ones costing 5 Yen per message. A company can send up to 45,000 included messages with the standard plan. LINE charges approximately 3 Yen for additional ones.
