Introduction

Reaching customers directly is becoming harder for global ecommerce companies. Competition is increasing, traffic is expensive, and users often leave a website without taking action. This is especially true in East Asia and Southeast Asia.

LINE is the dominant messaging app in these regions. It has become part of daily communication across Japan, Taiwan, and Thailand. In Japan alone, LINE reported more than 86 million monthly active users in 2024, covering nearly 70% of the entire population. Compared with email’s average open rate of around 20%, LINE messages often reach 70% to 90% open rates. Users also respond faster and are more willing to chat or buy inside LINE.

For online store owners, this makes LINE more than a messaging channel. It becomes a private, high-intent traffic asset. A LINE entry point on your store allows you to move users from “anonymous website visitor” to “repeatable, multi-touch communication.”

This guide will show you how to set up an effective LINE entry point on your ecommerce site, step by step, and use it to drive acquisition, conversion, support, and repeat purchases.

Why Your Store Should Add a LINE Entry Point

A LINE entry point is a simple button or chat entrance that connects your store to your LINE Official Account. Although the setup may seem small, its impact on your business can be substantial. It strengthens every stage of the customer lifecycle.

We break the value into four key stages.

1. Acquisition: Lower cost, stronger traffic retention

Many visitors leave a store after one or two page views. Adding a LINE entry point helps you convert these one-time visitors into LINE friends whom you can message later.

This improves traffic retention and builds your private audience for future promotions. Instead of paying for ads again, you can re-engage users directly through LINE.

2. Conversion: Higher consultation and order rates

When shoppers have questions about color, size, shipping or discounts, they often leave the site. A LINE button on the product page lets them ask instantly.

Brands that respond quickly through LINE often see:

• more conversations
• fewer abandoned sessions
• higher order rates

Because users feel taken care of, they make faster, more confident purchase decisions.

3. Customer Support: Faster replies and better satisfaction

You can automate many support questions inside LINE, including:

• order tracking
• shipping updates
• return or exchange requests

Quick replies reduce wait time and improve satisfaction. Satisfied users are more open to future purchases.

4. Retention & Repurchase: Activate users with high open rates

LINE is a high-visibility channel. When you send a promotional message, new launch or discount offer, most users will open it.

This makes LINE one of the strongest tools for repeat purchases in East Asia and Southeast Asia. You can reach users instantly and bring them back to your store at a much lower cost than paid ads.

Outcome: A complete, sustainable customer funnel

With a well-placed LINE entry point, your independent store gains a direct and sustainable communication loop:

Visitor → LINE friend → Conversation → Conversion → Support → Repurchase

This creates long-term value and helps your business stay competitive in the fast-moving ecommerce market.

Three Official LINE Buttons You Can Add to Your Store

LINE provides three standard entry types. These are easy to embed and work well for basic user actions.

1. Share Button

Let users share your site and increase organic reach**

When to use

The LINE Share Button helps you drive viral traffic. Visitors can share your store URL directly with friends or group chats.

Best for

• Product pages with strong demand
• Limited-time campaigns
• Referral or group-buy promotions

Setup Steps

1. Please enter your store URL > Choose the button style, size, and color > Preview the button > Copy the code snippet > Paste it into the page where you want the button to appear.

Important
If a page contains several LINE Share buttons, you only need to insert the script tag once.

Expected Outcome

Your website gains more peer-to-peer shares, which often convert better than ads because the recommendation comes from friends.

2. Add Friends Button

Turn visitors into long-term LINE contacts**

When to use

This is the most essential button for private traffic growth. After browsing your site, users can follow your LINE Official Account with one tap.

Prerequisite

You must already have a LINE Official Account set up.

Setup Steps

Enter your LINE Official Account ID > Choose a button style, including the option to show your follower count > Preview the final button > Copy the code snippet > Paste it into the page.

Expected Outcome

Your store converts anonymous visitors into reachable users. You can send future campaigns, promotions or updates directly via LINE.

3. Like Button

Collect user sentiment and amplify content visibility.

When to use

The Like Button gives you direct feedback on whether users enjoy your content. You can also place Share or Add Friend buttons next to it for higher engagement.

Two common combinations

Setup Steps

Enter your website URL > Select whether you want to pair the Like button with Share or Add Friend > Preview the button > Copy the code snippet > Paste it into your site.

Expected Outcome

You collect user feedback, expand your exposure, and convert engaged users into LINE friends.

You can configure:

Recommended best practices for ecommerce brands:

• Use a green theme to match LINE’s visual expectations.

Expected Outcomes After Setup

With this setup, your store gains:

• A visible LINE icon that increases consultation rates
• More LINE friends are added automatically
• A complete view of each session’s source page
• Clear analytics showing which pages drive the most clicks
