In an era of rapid digital transformation, SEO has become a cornerstone of online success for brands in Vietnam. Choosing the right seo agency Vietnam can make a major difference in visibility, traffic, and business growth.
As an agency for digital marketing, On Digitals is constantly analyzing the shifts in SEO practices, market dynamics, and emerging threats. Below are the most critical developments and news items shaping the SEO agency landscape in Vietnam today.
SEO Outsourcing Boom & Market Growth
SEO outsourcing is on the rise globally, and Vietnam is not exempt from this trend. According to recent forecasts, the SEO service market is projected to reach USD 106.9 billion by the end of 2025, growing at a compound annual growth rate (CAGR) of 18.3% from 2024.
What this means for Vietnamese SEO agencies:
-
Many agencies are expanding partnerships with offshore teams or specialized contractors to handle tasks like keyword research, content writing, and link building.
-
Scalability becomes a key competitive advantage: agencies able to scale resources quickly can serve more clients efficiently.
-
The focus shifts to quality control, process standardization, and oversight, to ensure outsourced work meets brand and technical standards.
As a forward-looking seo agency Vietnam, On Digitals monitors such trends to decide which capacities to build in-house and when to outsource selectively.
Intensifying Competition & More Agencies Listed
Vietnam’s SEO agency ecosystem is becoming more saturated, with many new players and listings emerging. For example:
-
Prodima, a Ho Chi Minh City–based digital marketing firm, continues to promote its SEO, PPC, social media, and web development services.
-
On Clutch’s directory of Top SEO Firms in Vietnam lists multiple agencies, reflecting growing demand and competition.
-
Outsource Accelerator’s “Top 10 SEO agencies in Vietnam” includes On Digitals among other notable names like AJ Marketing, Saigon Digital, Iris Marketing Agency, etc.
This intensifying competition pressures agencies to differentiate themselves via specialization (e.g. eCommerce SEO, local SEO, enterprise SEO) and by offering integrated agency for digital marketing services, not just SEO.
Evolving SEO Landscape in Vietnam for 2025
As search engines and user behavior evolve, Vietnamese agencies must adapt. According to a recent industry review, the SEO landscape in Vietnam in 2025 is projected to be more competitive and dynamic than ever.
Key shifts include:
-
Algorithm updates & AI influence: Search engines increasingly use AI, machine learning, and natural language understanding. SEO strategies must integrate semantic search, E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness), and content depth.
-
Mobile-first & Core Web Vitals: As mobile usage dominates, performance metrics like page speed, layout stability, and interactivity are crucial ranking signals.
-
Local and voice search dominance: Many searches in Vietnam are location-based or voice-driven. SEO agencies must optimize for conversational queries, “near me” intent, and local map listings.
-
Zero-click / Featured Snippet focus: Gaining placement in knowledge panels, featured snippets, or direct answer boxes becomes strategic, not just secondary.
-
Cross-channel integration: SEO cannot work alone; agencies increasingly integrate SEO with content marketing, social media, paid ads, PR, and influencer outreach to reinforce signals.
As an agency for digital marketing, On Digitals is adjusting service offerings to address these changes for instance, combining SEO with content and media strategies to maximize visibility.
SEO Poisoning & Cyber Threats Targeting Vietnamese Websites
One alarming trend impacting SEO agencies and their clients in Vietnam is SEO poisoning via malware. A recent report uncovered a malware campaign named BadIIS that targets East Asia, including Vietnam, by manipulating search results and redirecting traffic.
How it works:
-
Attackers infiltrate web servers (especially IIS) and inject malicious modules that intercept legitimate search traffic.
-
Victims’ websites may appear in search results but redirect users or serve malicious content.
-
Such attacks damage reputation, reduce trust, and can lead to deindexing by search engines if flagged.
For seo agency Vietnam and clients, this raises the importance of security measures: regular server audits, integrity checks, intrusion detection, and collaboration with web security teams. On Digitals ensures client sites remain secure while optimizing SEO.
SEO Conferences & Knowledge Sharing in Vietnam
Staying current requires continuous learning and community engagement. In 2025, one notable event is the SEO Mastery Summit held at JW Marriott Saigon, Ho Chi Minh City.
Highlights:
-
Workshops, case studies, and expert panels focusing on SEO, AI in search, and emerging trends.
-
Networking opportunity for SEO professionals, agencies, and marketers to exchange tactics and tools.
-
Helps local agencies like On Digitals stay on the cutting edge and bring fresh insights to clients.
Attending or sponsoring such events not only benefits agency staff skills but also strengthens brand credibility.
