In 2025, influencer marketing for e-commerce is no longer just an optional tactic—it has become one of the primary “growth engines” for online businesses. According to Nielsen, 88% of consumers trust product recommendations from KOLs/KOCs because of their authenticity and expertise. Statista also reports that 79% of Vietnamese consumers decide to purchase after receiving a KOL’s recommendation.

On platforms like Shopee, Lazada, and TikTok Shop, KOLs (Key Opinion Leaders) and KOCs (Key Opinion Consumers) have proven effective not only in driving brand awareness but also in directly increasing sales. This is why more and more e-commerce businesses are investing heavily in influencer marketing campaigns to reach their target customers effectively.

I. Understanding Influencer Marketing in E-Commerce

1. Definition of KOL and KOC

  • KOL (Key Opinion Leader): Individuals with significant influence in a specific field, often celebrities or industry experts. They are ideal for campaigns aimed at building brand image and initial trust.
  • KOC (Key Opinion Consumer): Actual consumers, often with smaller followings, but who build credibility through authentic and relatable product reviews.

2. Differences Between KOL and KOC in E-Commerce

  • KOL: Helps rapidly boost brand awareness through broad influence. For example, when a cosmetic brand collaborates with a well-known beauty blogger, the product quickly gains exposure to millions of potential customers.
  • KOC: Focuses on authenticity and conversion. A KOC might only have a few thousand followers, but their realistic product review videos often result in high purchase rates.

3. Combining KOL and KOC in 2025 Campaigns

Today’s e-commerce brands often combine both KOL and KOC in their strategies—KOLs to create awareness and KOCs to drive conversions. Key trends include:

  • Micro- and Nano-influencers: Smaller followings but higher engagement rates, helping reach more targeted audiences.
  • UGC (User Generated Content): Organic content, especially casual TikTok review videos, is becoming a powerful driver of trust while optimizing advertising costs.

II. Benefits of Influencer Marketing in E-Commerce

1. Boosting Trust and Conversion Rates

KOC product reviews provide real-life experiences, reducing customer skepticism. When consumers see real people using real products, their likelihood of purchasing skyrockets.

2. Reducing Advertising Costs Through Organic Reach

Instead of spending heavily on display ads, a strong e-commerce influencer campaign generates authentic, shareable content that spreads organically—cutting down the need for paid media.

3. Supporting Multi-Channel SEO

KOL/KOC reviews, videos, and posts not only drive conversions but also improve search visibility across e-commerce platforms and search engines by leveraging SEO-friendly content.

4. Building Loyal Customer Communities

Influencer marketing doesn’t just drive one-time sales—it builds lasting trust and nurtures communities of loyal customers who advocate for the brand.

III. 5 Strategies for Effective Influencer Marketing

1. Define Clear Campaign Objectives

Before launching, identify specific goals:

  • Brand Awareness: Partner with top-tier KOLs to create massive visibility.
  • Sales Growth: Focus on KOCs to generate authentic reviews that drive conversions.
  • New Product Launches: Combine KOLs for awareness and KOCs for social proof.

2. Choose the Right KOLs/KOCs for Your Industry

Not every influencer fits every product. For example:

  • Fashion: Collaborate with fashion influencers to boost brand credibility.
  • Beauty: Use KOC beauty reviewers for authentic product demonstrations.
  • FMCG or Home Goods: Leverage micro-KOCs for relatable, practical product reviews that encourage repeat purchases.

For businesses, choosing the right influencer can determine the success of a campaign. This is why many brands partner with N-Squared E-Commerce Vietnam – a company with extensive experience connecting hundreds of cross-industry KOLs and KOCs. N-Squared not only helps shops find influencers that fit their budget but also optimizes campaigns to target the right audience, increasing conversions without unnecessary costs.

3. Develop Creative Content

Content is the heart of any influencer campaign:

  • Livestream Selling: Invite KOLs/KOCs to host interactive sessions and close sales live.
  • Short TikTok Videos: “Before-and-after” transformations, trend-driven content, and real reviews perform best.
  • In-Depth Reviews (Blogs or Shopee Feed): Detailed content to convert buyers in the final stage of their journey.

4. Measure Campaign Performance

Track these key metrics to gauge success:

  • Engagement Rate (ER)
  • Click-Through Rate (CTR)
  • Revenue Generated from Influencers
  • Cost Per Acquisition (CPA)

This data helps optimize budgets and identify the influencers with the best ROI.

5. Amplify Content with Paid Ads

To maximize impact, repurpose influencer content in paid campaigns:

  • TikTok Spark Ads: Boost authentic influencer videos directly.
  • Shopee or Lazada Sponsored Ads: Feature KOC content in top search positions.
  • Meta Ads (Facebook/Instagram): Use influencer content for retargeting campaigns.
