Chapter 1: The transformation of Vietnam's SEO market and the digital economic landscape of 2026
The search engine optimization (SEO) market in Vietnam in 2026 witnessed important turning points when Google's algorithms completely shifted to the entity ecosystem (Entity) and general search experience (SGE). According to observations from Tan Phat Digital, the concept of "renting SEO" has evolved from buying ranking positions to investing in a sustainable revenue growth channel. The emergence of AI Overviews (AIO) forces service providers to change their cost structures to meet strict standards of E-E-A-T (Expertise, Experience, Authority and Trust).
Determining the investment budget for SEO in 2026 is no longer based on emotions. Actual analysis shows that SEO costs in Vietnam have a clear differentiation: from basic management packages for micro-enterprises (SMEs) with a price of about 6 million VND/month to corporate-scale campaigns of up to billions of VND for the entire project. This differentiation reflects the huge amount of work that needs to be done to maintain position in an extremely competitive market.

Chapter 9: The future of SEO and the impact of AI on the 2026 budget
The year 2026 marks the inevitable shift to the machine age. At Tan Phat Digital, we realize that SEO is no longer a race about keyword density but has become a battle about "Semantic Overlap" (Semantic Overlap) and AI's citation ability.
9.1. From "Keyword Optimization" to "Answer Optimization" (AIO & SGE)
The customer journey in 2026 no longer starts from the search bar and ends at the website. The popularity of AI Overviews (AIO) creates a Zero-click environment, where users receive answers right on the results page.
Budget impact: Businesses need to spend an additional 15 to 30 million VND/month to optimize "Agent Browsers" and ensure brands appear in AI snippets.
Changes strategy:Instead of producing 100 short articles, the budget was put into creating 10 high-quality "Proof blocks" so that machines can easily retrieve and verify information.
9.2. "Vector Index Cleaning" Cost
AI uses vector space to rank content of equivalent meaning. Websites containing "dirty" data (junk content, messy structure) will be removed by AI to avoid risks to users.
Architect's thinking: Website needs to be managed like a data pipeline (Data Pipeline). Technical Audit costs in 2026 typically increase by 20% to include data normalization for large language models (LLMs).
AI Consistency Paradox: If brand information on websites, social networks and newspapers is inconsistent, AI will have difficulty understanding the nature of the business. This forces businesses to invest in synchronous Entity Branding packages with fees ranging from 5 to 15 million VND for the initialization phase.
9.3. The explosion of Multimodal Search
Query volume expands strongly thanks to voice and images. Optimizing for AI doesn't stop at text:
- (EEAT), instead of just using AI to write articles automatically.
9.4. Information verification is the new measure of trust
In an era where AI content is widespread, Google and search AI engines will de-prioritize crawling/indexing low-value pages.
Expert costs: Projects in the Health and Finance (YMYL) industries are required to have human authentication. Hiring leading industry experts to evaluate content or act as an entity representative can cost an additional 10 to 50 million VND/project depending on scale.
Digital PR: Budget to invest in journalism and reputable platforms not only to get backlinks but also to "earn mentions" to build trust for algorithms AI.
10.1. "Eat for sure" mindset and barriers to digital transformation
The majority of small businesses and stores in Vietnam still maintain family-style management, no books and are afraid of contact with new technology.
Afraid of "going big": Many business owners are afraid of tax regulations and legal inspections when expanding online. This leads to them only investing in SEO moderately, not daring to make breakthroughs.
Immediate survival: SMEs often prioritize expenses that bring immediate cash flow. Meanwhile, SEO is a long-term strategy that is often "put aside" to make room for short-term needs. This thinking creates a loop: no SEO -> dependent on advertising -> thin profits -> no money to invest in SEO.
10.2. Budget Trap and the "Zombie Situation" of small businesses
The heartbreaking reality in 2026 is that many small businesses enter a "zombie" state: not dead but unable to grow.
Budget "breaks down in the middle of the road": Many SMEs only prepare an SEO budget enough for 1-2 months. When they did not see immediate results (which took 3-6 months), they decided to stop, leading to wasting all the money they spent without achieving any growth milestone.
Growth by "Doping": Vietnamese SMEs are too dependent on paid advertising as a forced "ventilator". Buying traffic instead of building internal assets causes them to lose control of customer data and brand ownership.
10.3. Human resource challenge: "One person carries five shoulders"
The shortage of high-quality human resources is the biggest barrier for SMEs when implementing SEO.
Overload and lack of depth: Due to limited budget, a marketing staff at a small store often has to do both content, design, running Ads and SEO. This leads to fragmentation, lack of technical depth and unstable efficiency.
Risk from Account Junior: When hiring a cheap agency, SME projects are often assigned to inexperienced interns or juniors to supervise. If the brief is not clear, the entire campaign will deviate from the core values of the business.
10.4. Floor Fee Spiral and Tax Pressure 2026
In 2026, online businesses face the tightening of laws and platforms:
Dependence on e-commerce platforms:Small merchants on Shopee and TikTok Shop are having their profit margins squeezed by floor fees and devaluation wars from competitors. Not owning their own website makes it easy for them to lose their store after just one policy change.
Multi-source data scanning tax: From January 1, 2026, revenue from all platforms will be combined and automatically checked through electronic invoices and digital transactions. This forces business individuals to be financially transparent and standardize the website system for more sustainable cash flow management.
10.5. Dangers from "Black Hat" SEO and malicious code
Due to the desire for cheap and the desire to get to the top quickly, many small shops fall into the trap of individuals providing fraudulent SEO services:
Risk of Sandbox: Shooting fake traffic or spamming links causes the website to be permanently Sandboxed by Google. Many shop owners lost hundreds of millions but the digital asset they received was only a domain name listed on the "black list".
Malicious code and dirty data: Small websites are often not secure, easily susceptible to Japanese malware (Japanese Keyword Hack). In the AI era, algorithms will completely eliminate these dirty data sources, rendering SEO efforts meaningless.
10.6. "Lean SEO" solution for beginners
Tan Phat Digital proposes an escape route for small groups:
Owning data: Shifting from "hiring" customers through advertising to "owning" customers through websites and SEO.
Local SEO is the focus: Focus on SEO Maps and local keywords to attract actual customers at the point of sale at low cost.
"Companion"-style cooperation:SMEs should look for agencies with KPI commitments on real behavior (click hotline, zalo) instead of just looking at the number of soulless keywords.
