Practical tutorial on data detection: How to screen numbers in batches and improve B2B overseas customer acquisition and SEO effects

In the B2B overseas customer acquisition scenario, data detection usually refers to multi-dimensional verification and screening of batch mobile phone numbers such as validity, activity, platform activation status, and even gender, age, etc. For teams that rely on instant messaging tools such as Telegram, WhatsApp, and Line for community operations or private message promotion, sending messages directly without data detection often leads to a large number of invalid numbers, wasted costs, account closures, and extremely low conversion rates. On the other hand, high-quality numbers obtained through accurate data detection can also indirectly serve SEO strategies - such as sharing website external links in verified and active Telegram groups, or sending content to users of a specific gender/region, thereby improving external link click-through rates and natural search rankings. This article will start from scratch and teach you step by step how to complete a complete data detection operation through the KK-DATA platform, and explain how to apply the data detection results to B2B overseas customer acquisition and website promotion.

What is data detection? Why is it important for B2B to acquire customers overseas?

Data detection (Number Validation & Screening) is not a simple number format check, but:

• Activation detection: Confirm whether the number has been registered on the target platform (Telegram, WhatsApp, Line, Zalo, etc.).
• Activity Detection: Determine whether the number has online records within the specified time window (such as Telegram’s “Last Online Time”).
• Gender Identification: Some platforms (Telegram, Line, Zalo, etc.) support detecting account gender, and some also include fields such as age and avatar.
• Multi-platform cross-validation: The status of the same number on multiple platforms helps locate common channels for target groups.

For B2B overseas teams, these data directly determine the accuracy and cost of promotion:

• Cost Savings: Avoid sending marketing messages to invalid numbers and reduce channel costs.
• Improved conversion rates: Only send material to active, gender-matched users.
• Protect Account Reputation: Sending messages to unregistered numbers in batches may trigger account ban on the platform.
• Support SEO external link construction: Use active Telegram and WhatsApp groups to share links to blogs or product pages, which can naturally increase the diversity of external links and improve search engines’ evaluation of the website’s authority (both Google and Bing recognize the positive effects from social signals).

Preparation work before data detection: registration and recharge

Before starting data detection, you need to prepare your KK-DATA account number and balance. The platform adopts a bill-by-item and no-subscription package model, which is suitable for flexible use.

Complete account registration in the console

1. Visit KK-DATA Application Console and click the “Register” button.
2. Enter your email address, set a password, and complete email verification.
3. After logging in, you can see the API key (for integrated development) in the “Personal Center” on the left menu, as well as the “Task Management” module for subsequent operations.

Deposit USDT and confirm balance

KK-DATA supports anonymous deposit of USDT (TRC20), with a minimum of about 50 USDT.

1. Click “Recharge” on the left side of the console to obtain the recharge address.
2. Transfer funds to this address from your wallet or exchange and wait for on-chain confirmation (usually a few minutes).
3. After receiving the account, you can check the updated USDT converted into platform points in the “Account Balance”. The actual unit price is subject to the real-time price of the console. Different platforms (Telegram/WhatsApp/Line/Zalo, etc.) and different detection types (activation/active/gender) have different fees.

Step 1: Generate target number list

The first step in data detection is to prepare the number to be detected. You have two ways to get a list of numbers:

Method 1: Randomly generate global numbers

KK-DATA provides global number generation function, covering 240+ countries and regions, and supports generation by country, number segment, and operator.

• Enter the “Number Generation” page and select a country (such as India, Indonesia, Brazil, etc.).
• The number segment prefix can be set (for example, a number segment starting with Indonesia +62) or randomly generated.
• The number of generated items can be customized, up to hundreds of thousands at a time. Generate for free, no balance will be deducted.
• Export to CSV file, or copy directly to clipboard.

Method 2: Custom number segment CSV import

If you already have a list of target country number segments (for example, from the operator’s official website or historical data), you can upload a CSV file, and the platform will automatically parse and generate all permutations and combinations of numbers.

• Format requirements: The first column is the country code (without the + sign), the second column is the number segment prefix (without the country code), and the third column is an empty note.
• After uploading, the platform will generate a complete number list in international format.

Suggestion: For B2B overseas promotion, give priority to countries with main target markets. For example, for B2B customers in Southeast Asia, we focus on generating numbers in Indonesia, Vietnam, Thailand, and the Philippines. After generation, you can directly enter the second step of screening.

Step 2: Multi-platform screening - activation, activity, gender detection

Import the number list generated in the previous step into the screening task. KK-DATA supports detecting multiple platforms at the same time, with a maximum of about 1 million items in a single task.

Create Telegram screening task

1. Enter “Task Management” → “New Task”.
2. Select the Telegram detection type.
   • Telegram activation detection: Verify whether the number is registered with Telegram. Output fields: number, city, country, tg status (activated/unregistered).
   • Telegram activity detection: You can specify the activity window (such as “last 7 days”, “last 30 days”). Output fields: number, last online time, and whether it is active within the specified window.
   • Telegram Gender Detection: not only displays gender (male/female/unknown), but also includes age field. Note: This is an inference based on public information and is not ID card-level accuracy, but it can be used for marketing targeting (for example, screening people around 30 years old).
   • tgid export: If you need to further operate through the user ID (tgid) in Telegram, you can export it together with this task.
3. Upload the number file (supports TXT or CSV, one number per line).
4. The system automatically calculates the estimated deductions and submits the task after confirmation. After the task is completed, you will be notified through Telegram (you need to bind the notification robot in advance).

Create WhatsApp screening task

Similarly, select WhatsApp platform, optional:

• WhatsApp activation detection: Whether the number is on WhatsApp.
• WhatsApp activity detection: recent online time (limited by WhatsApp privacy policy, the results are timely).
• WhatsApp Gender Detection: Gender can be identified for some numbers.

Create Line screening task

Line is widely used in Japan, South Korea, Taiwan and some Southeast Asian markets. Line screen number can detect:

• Line activation detection: whether to register Line.
• Line Activity Detection: Account activity records.
• Line Gender Detection: Especially suitable for accurate male/female orientation, and exports Line UID, which can be used for subsequent friend additions or group invitations.

Zalo screen number (recommended for Vietnam market)

Zalo is a national app in Vietnam. Zalo screening supports activation, activity, and gender detection, which is particularly important for B2B marketing teams in Vietnam.

Multi-platform synchronization detection

If you want the same number to detect multiple platforms at the same time, you can create a “comprehensive task” and check multiple platforms. The platforms will be detected in turn and output the status field of each platform.

Step 3: Export the filter results and use them for customer acquisition and SEO

After the task is completed, click “View Details” in “Task Management” to preview the results, or directly download the CSV or TXT format file. Export fields vary by platform and detection type, but generally include:

• number
• Platform status (activated/not activated/active/inactive)
• Gender (male/female/unknown)
• Age (Telegram gender detection only)
• City/Country (some platforms)
• ID within the platform (tgid, wsid, uid, etc.)

Use data for B2B overseas customer acquisition

• Private message promotion: Import the number with male gender into WhatsApp or Telegram broadcast tool and send product introduction.
• Community Recruitment: Use tgid export to send group invitation links to target users through Telegram API.
• Associated SEO external link construction: In active Telegram groups, share high-quality blog articles on the website in a non-advertising form to attract users to click and increase external link exposure. Both Bing and Google will use sharing on social platforms as a positive signal of website weight.

How does data detection directly improve SEO effects?

Data detection generates a list of numbers that can help you:

• Precise content distribution: Screen out male users around 30 years old and push B2B content related to their industry (such as “Industrial Automation Solutions”) to increase click-through rates and dwell time.
• Reduce bounce rate: Since users are interested in your content, they will be more willing to visit the website and browse other pages, reducing the bounce rate, which indirectly benefits SEO.
• Build external link resources: Use verified and active Telegram groups, Line communities, etc. to share website pages to form natural external links. Be careful to avoid spam links, and Bing pays special attention to the contextual relevance of links.

FAQ

**Q: Will data detection expose my number list? Will the number be leaked? ** Answer: KK-DATA strictly protects the privacy of user data. All task data is only stored in encrypted servers. Users can delete it after completing the task. The platform will not provide numbers to third parties. It is recommended to clean sensitive data in historical tasks regularly.

**Q: Is the age in Telegram gender detection accurate? Can I use it directly to target the “30-year-old crowd”? ** Answer: The age field is inferred based on public information (such as Telegram profile birthday, nickname implicit information, etc.) and is not officially certified data. The average accuracy is about 70%–80%. It can be used as a reference for crowd portraits, but it is not recommended for accurate ID card-level judgment. Screening “people around 30 years old” is a reasonable usage scenario.

**Q: How many numbers can be detected at most at one time? How long does it take to complete the task? ** Answer: The maximum number of single tasks is about 1 million. Completion time depends on number of numbers, type of detection platform, and concurrent load on the system. Usually, 10,000 Telegram activation tests can be completed within a few minutes; tests including activity and gender will be slightly slower. An estimated duration will be displayed when the task is created.

**Q: If the task has not been submitted after recharging, can the balance be refunded? ** Answer: USDT is non-refundable after recharging, but the balance is permanently valid and has no expiration time. The unused balance can be reserved for next use. It is recommended to recharge 50 USDT for the first time, and then decide whether to increase the amount after experiencing it.

**Q: How to export the data detection results and how to use them in SEO external links later? ** Answer: The results support CSV and TXT export. You can use the telegram group ID (tgid) or Line ID in the exported data to manually join the group and share your website content. Additionally, for WhatsApp, a verified active number can be used to send personalized messages via the WhatsApp API with a website link.
