Market Booking KOL/KOC in Vietnam is developing at a breakneck pace. According to recent reports, the global Influencer Marketing market size has exceeded 21 billion USD in 2023. In Vietnam, this is also a key marketing channel for many SMEs.
However, behind those flashy numbers lies a reality full of risks. As experts at DPS.MEDIA, we have witnessed countless bitter campaign failures. Many businesses lose hundreds of millions of dong just due to lack of real-world experience.
Vấn đề không chỉ dừng lại ở việc lãng phí ngân sách. Việc chọn sai người, bị thổi giá, hay tồi tệ hơn là bị “bùng lịch” sát giờ G gây ảnh hưởng nghiêm trọng đến uy tín thương hiệu. Kế hoạch ra mắt sản phẩm có thể bị trì hoãn vô thời hạn.
Bài viết này là sự đúc kết kinh nghiệm “xương máu” của chúng tôi từ năm 2017 đến nay. Chúng tôi sẽ vạch trần những chiêu trò phổ biến trong ngành. Mục tiêu là giúp các doanh nghiệp SMEs làm chủ quy trình Booking KOL/KOC safely and most effectively.
The Painful Reality and Risks When Businesses Self-Book KOL/KOC

The Allure of Influencer Marketing and Harmful Misconceptions
Nhiều chủ doanh nghiệp SMEs bị hấp dẫn bởi những câu chuyện thành công “đổi đời” nhờ KOL. Họ lầm tưởng rằng chỉ cần bỏ tiền thuê người nổi tiếng review là đơn hàng sẽ về tới tấp. Đây là một tư duy hết sức ngây thơ và nguy hiểm trong bối cảnh cạnh tranh hiện nay.
Self-contacting Booking KOL/KOC tưởng chừng đơn giản nhưng lại ẩn chứa nhiều cạm bẫy. Nếu không có quy trình đánh giá bài bản, bạn rất dễ rơi vào ma trận của các con số ảo. Hậu quả là ngân sách “bốc hơi” nhanh chóng mà không mang lại doanh thu thực tế.
Chưa kể, việc thiếu kinh nghiệm đàm phán khiến doanh nghiệp thường xuyên bị ép giá. Nhiều bạn trẻ mới nổi tiếng thường đưa ra mức giá “trên trời” không tương xứng với hiệu quả. Sự thiếu hiểu biết về mặt bằng giá thị trường là điểm yếu chí mạng của các doanh nghiệp tự triển khai.
Sự hỗn loạn của thị trường “vàng thau lẫn lộn”
Thị trường KOC/KOL hiện nay đang ở trong tình trạng “trăm hoa đua nở” nhưng thiếu quy chuẩn. Bất kỳ ai có vài nghìn người theo dõi cũng có thể tự xưng là Influencer và nhận booking. Điều này tạo ra một môi trường cạnh tranh không lành mạnh và đầy rẫy sự gian dối.
Tình trạng mua bán lượt theo dõi (follow), lượt thích (like) và bình luận (comment) diễn ra công khai. Một tài khoản có vẻ ngoài hào nhoáng với hàng trăm nghìn follower có thể chỉ là một “xác rỗng”. Nếu doanh nghiệp Booking KOL/KOC relies on these metrics, failure is certain.
List of common risks when businesses operate it themselves:
- Cannot distinguish real metrics from fake ones.
- Lack skills in negotiating prices and accompanying benefits.
- Loose contracts without clear responsibility clauses.
- No contingency plan if the KOL encounters issues or flakes.
- Difficulty measuring the true effectiveness of the campaign.
- Wasting too much time on management and reconciliation instead of focusing on business.
Real-Life Examples of Failures Due to Lack of Experience
We once received a client, brand A cosmetics. They spent 50 million VND themselves to hire a hot girl on Instagram with 200k followers. The result was the post only got a few hundred pitiful likes and no orders at all.
Another case is restaurant chain B. They Booking KOL/KOC in the food sector to review new dishes. However, on the appointed day, this KOL suddenly reported being busy and requested an indefinite postponement. The restaurant's opening plan was seriously affected, causing significant loss in expected revenue.
Lessons learned: Never underestimate the complexity of managing Influencers. Thorough preparation and market knowledge are crucial before investing in any booking activity.
Why Booking KOL/KOC Often Faces Price Inflation and How to Spot It

Cơ chế “làm giá” của các Influencer và quản lý
Việc thổi giá thường xuất phát từ sự bất cân xứng thông tin giữa người mua và người bán. Các KOL/KOC, đặc biệt là những người có quản lý (manager), thường có nhiều chiêu trò để nâng giá trị ảo của mình. Họ nắm bắt tâm lý “sợ bỏ lỡ” của nhãn hàng để ép giá.
Một chiêu bài phổ biến là sử dụng các “rate card” (bảng giá) được thiết kế rất chuyên nghiệp nhưng mức giá lại cao hơn 30-50% so với giá trị thực. Họ thường viện cớ vào độ phủ sóng, hình ảnh thương hiệu cá nhân để biện minh cho mức giá vô lý đó.
If you don't know the average market prices for each segment, you'll easily accept these rates. At DPS.MEDIA, we have historical pricing data for thousands of KOLs for comparison, helping clients avoid being ripped off when Booking KOL/KOC.
Identifying Fake Metrics Used for Price Inflation
Nhiều KOC/KOL sử dụng các công cụ tăng tương tác ảo để làm đẹp hồ sơ năng lực. Họ mua like, comment từ các “click farm” (trại cày view) để đánh lừa nhãn hàng về mức độ ảnh hưởng của mình. Việc phát hiện ra điều này đòi hỏi sự tinh ý và công cụ chuyên dụng.
Be wary of accounts with large follower counts but extremely low engagement rates (Engagement Rate). For example, a 100k follower account with only 200-300 likes per post is highly suspicious. A huge discrepancy is a red flag.
Another sign is superficial, generic comments or unrelated foreign language ones under posts. These are often bots or cheap engagement services. Don't let these numbers fool you when conducting Booking KOL/KOC.
| Comparison Criteria | Real engagement metrics (Organic) | Fake/Bot engagement metrics |
|---|---|---|
| Engagement Rate (ER) | Stable, appropriate to follower scale (usually 1-5%) | Very low or abnormally high spikes in a few posts |
| Comment quality | Relevant to content, emotional, diverse | Chung chung (“Tuyệt”, “Đẹp quá”, icon), lặp lại, sai ngữ cảnh |
| Follower growth | Steady growth over time and activity | Sudden spike in short time (due to buying followers) |
| Followers | Real accounts, active, with profile pictures | Fake accounts, no profile pictures, meaningless usernames |
Negotiation Tactics for Reasonable Pricing
Never accept the first price offered by the KOL. Consider it the starting point for negotiation. You need to prepare data on their recent performance to use as a negotiation basis.
Propose long-term cooperation packages or combos of multiple posts for better discounts. Committing to a large number of bookings often gives you an advantage in price negotiation. At the same time, clarify accompanying benefits like using images for advertising.
You can also propose performance-based collaboration (CPD, CPS, CPA) instead of just paying a fixed fee per post. This shares risk and motivates the KOL to work harder to drive sales when you Booking KOL/KOC.
Real-Life Examples of Price Inflation and How to Handle Them
A fashion brand was quoted 80 million for a TikTok video from a Hot TikToker. After our analysis, we found their conversion rate was very low. We negotiated down to 40 million with a bonus clause if sales KPIs were met.
Another case, a KOL quoted 15 million for a Facebook post. We discovered 60% comments on their page were from fake accounts. We presented evidence and demanded a realistic price of 5 million, or we'd find someone else.
Lessons learned: Information is power in negotiation. Always thoroughly check metrics and don't hesitate to bargain based on the real value the KOL can bring to your business.
“Ác mộng” bùng lịch khi Booking KOL/KOC và biện pháp phòng tránh

Tại sao KOC/KOL lại “bùng lịch” hoặc chậm trễ?
The issue of no-shows (ghosting) or delayed deadlines is a constant headache for brands. The most common cause is KOLs taking on too many jobs at once, leading to overload. They lack professional time and task management.
Một số trường hợp khác là do KOL gặp vấn đề cá nhân đột xuất, hoặc đơn giản là họ cảm thấy “không hứng thú” với sản phẩm của bạn nữa. Thái độ làm việc thiếu chuyên nghiệp là một căn bệnh khá phổ biến trong giới influencer trẻ tuổi hiện nay.
Sometimes, the cause comes from the brand side when the brief (requirement summary) is unclear. Constant changes make the KOL frustrated and avoidant. This is something to note in the process Booking KOL/KOC.
Severe Consequences of No-Shows
No-shows not only cause frustration but directly impact business plans. Marketing campaigns are tightly scheduled to catch events or shopping seasons. One broken link can derail the entire system.
For example, you plan a product launch on Black Friday and book 10 KOLs to post simultaneously. If 3 of them no-show at the last minute, the viral effect will be significantly reduced. The lost opportunity cost is huge.
Additionally, urgently finding replacements often forces you to accept higher prices or unsuitable faces. This reduces the overall campaign quality Booking KOL/KOC and wastes budget.
Sử dụng hợp đồng chặt chẽ làm “lá chắn” bảo vệ
Service contracts are the most important legal tool to protect business interests. A sketchy contract, just agreed via messages, is a recipe for disaster. All commitments must be clearly documented.
In the contract, clearly specify delivery time (deadline), number of posts, posting platforms, and content requirements. Especially, include specific penalty clauses if the KOL is late or fails to fulfill commitments.
Important clauses to include in KOL/KOC Booking contracts:
- Specific timelines for each stage: sending demo, content approval, post date and time.
- Rule against deleting posts for a certain period (e.g., 3 months).
- Specific fine for each late day (e.g., deduct 10% contract value/day).
- Exclusivity commitment (no advertising for competitors for a certain period).
- Ownership and usage rights of images/content after campaign ends.
- 100% refund clause if KOL unilaterally cancels without valid reason.
Real-Life Examples of Handling No-Shows
We worked with a Travel Blogger for a summer tour promotion. Close to the trip date, they canceled citing health reasons. Thanks to tight contract clauses, we demanded 100% deposit refund and partial damage compensation as stipulated.
Another example of delay: A tech KOC kept postponing video review deadline. After 3 ineffective reminders, we applied the contract penalty deduction. Immediately, the KOC completed the work the next day.
Lessons learned: Đừng tin vào lời hứa miệng. Hợp đồng là “thượng phương bảo kiếm” giúp bạn nắm quyền chủ động và giảm thiểu tối đa rủi ro khi làm việc với các đối tác thiếu chuyên nghiệp.
Standard Process for Professional KOL/KOC Booking to Minimize Risks

Defining Clear Goals and KOL/KOC Profiles
The first and most important step is to know what you want. Do you Booking KOL/KOC want to increase brand recognition (Branding) or to boost sales (Sales)? Different objectives will lead to the selection of completely different faces.
If you need to increase reach, choose Celebs or Macro-Influencers with massive fan bases. If you need to increase sales conversion rates, Micro-Influencers or KOCs (Key Opinion Consumers) with niche fan bases and high credibility will be much more effective.
Draw a detailed portrait of the target KOL: age, gender, content style, geographic area, and most importantly, whether their follower base matches your target customers.
Building a Detailed and Professional Brief (Requirement Summary)
A poor brief will lead to poor content. The brief needs to provide full information about the product, the main message (key message) to convey, and mandatory requirements (must-haves) in the post content.
However, don't turn the brief into handcuffs. Give the KOL space to create in their own style. The more natural the content, and the more it bears the personal imprint of the KOL, the easier it is for the audience to accept.
Clearly specify regulations on using hashtags, tagging the brand, and inserting purchase links (affiliate links). Clarity from the start will help avoid unnecessary disputes during implementation Booking KOL/KOC.
| Stage | Main activity | Estimated time |
|---|---|---|
| Preparation | Set objectives, budget, list potential KOLs | 1 week |
| Liên hệ & Đàm phán | Send brief, receive quotes, negotiate benefits and costs | 1-2 weeks |
| Ký hợp đồng & Thanh toán | Finalize terms, sign legal documents, advance payment | 3-5 days |
| Content Production | KOL develops ideas, sends demos, brand reviews and gives feedback | 1-3 weeks |
| Triển khai & Theo dõi | KOL posts according to schedule, brand monitors feedback | As per plan |
| Báo cáo & Nghiệm thu | Compile data, evaluate effectiveness, pay the remaining amount | 1 week after completion |
Vetting Process and Selection Procedure
Đừng chỉ nhìn vào số lượng follower. Hãy dành thời gian để ” soi” kỹ hoạt động của KOL trong ít nhất 3 tháng gần đây. Kiểm tra xem tần suất họ nhận booking quảng cáo có quá dày đặc hay không. Một profile “ngập lụt” trong quảng cáo sẽ khiến khán giả bị chai lì.
Evaluate image suitability (Brand Fit). A KOL specializing in luxurious lifestyles and designer goods will have a hard time convincing audiences to buy a cheap, everyday product. This forced mismatch is easily noticed by consumers.
At DPS.MEDIA, we apply a real competency assessment process which includes cross-checking data from multiple sources, analyzing the follower base, and preliminary interviews to assess work attitude before deciding to collaborate.
Examples of Successful Booking Processes
Our app launch campaign was a resounding success thanks to the systematic process. We selected 30 KOCs who were top students with influence in the learning community. The brief was designed openly, encouraging them to share real stories about improving grades thanks to the app.
As a result, the content created was very authentic, without overt advertising. The campaign achieved over 50,000 app downloads in the first month with a conversion cost (CPI) 40% lower than other channels.
Lessons learned: Professionalism in the process is the key to managing risks. Investing time in preparation and selection will save you a lot of money and effort during implementation Booking KOL/KOC.
Metrics to Measure Effectiveness After Booking KOL/KOC
Distinguishing Between Vanity Metrics and Actionable Metrics
Đừng để bị lóa mắt bởi số like hay số view. Đó thường chỉ là những “chỉ số phù hoa” (Vanity Metrics) không phản ánh đúng hiệu quả kinh doanh. Một triệu view nhưng không có ai quan tâm đến sản phẩm thì cũng vô nghĩa.
Hãy tập trung vào các “chỉ số hành động” (Actionable Metrics). Đó là những con số cho thấy người dùng thực sự quan tâm và có hành vi cụ thể. Ví dụ như số lượt click vào link, số lượng bình luận hỏi về giá hoặc nơi mua sản phẩm, số lượt chia sẻ bài viết.
When implementing Booking KOL/KOC, the ultimate goal is conversion. Therefore, prioritize metrics deeper in the marketing funnel rather than stopping at surface-level awareness.
Using Technology for Accurate Tracking and Measurement
Manual measurement by counting likes and comments is infeasible and inaccurate. Use supporting tools like UTM tracking links, unique discount codes (affiliate code) for each KOL to track order origins.
Social Listening platforms also help you measure the sentiment of user discussions about the brand after the campaign. You'll know if customer feedback is positive, negative, or neutral.
For large campaigns, investing in professional Influencer management software is essential. They provide visual reports, helping you see the full picture of investment effectiveness (ROI) of the activities Booking KOL/KOC.
List of important KPIs to track:
- Engagement Rate: (Like + Comment + Share) / Total Followers.
- Click-Through Rate (CTR): Number of link clicks / Total impressions or reach.
- Conversion Rate: Number of orders or leads / Total clicks.
- Cost Per Engagement (CPE): Cost per interaction.
- Cost Per Acquisition (CPA): Cost to acquire a new customer.
- Return on Ad Spend (ROAS): Revenue generated / Cost spent on KOL.
Post-Campaign Evaluation and Building Long-Term Relationships
Ending the campaign doesn't mean the work is done. Take time to deeply analyze the collected data. Compare effectiveness between different KOLs to find who is most suitable for your brand.
Dựa trên kết quả đó, hãy xây dựng danh sách “KOL ruột”. Đây là những người có hiệu quả công việc tốt, thái độ chuyên nghiệp và phù hợp với văn hóa thương hiệu. Hãy duy trì mối quan hệ tốt đẹp với họ cho các chiến dịch Booking KOL/KOC in the future.
Long-term collaboration often yields better results than one-off bookings. Audiences trust more when they see KOLs using and mentioning the product regularly and persistently over time.
Examples of Measurement and Optimization
In a campaign for a household brand, we issued unique discount codes to 5 different KOLs. Results showed KOL A had the lowest followers but highest sales due to a very quality and trusting fan base.
Conversely, KOL B had 5 times more followers but very low sales. Based on this data, in the next campaign, we cut budget for KOL B and invested more in KOL A, while signing a 6-month brand ambassador contract with them.
Lessons learned: Numbers don't lie. Let data guide your next investment decisions. Only when measured can you improve the effectiveness of activities Booking KOL/KOC.
