Best Website Redesign Services in Vietnam: Top 5 Companies for 2026

SmartOSC supports this broader approach by connecting experience design with digital commerce, application development, cloud infrastructure, Data & AI, cybersecurity, and enterprise system integration. Established in 2006, SmartOSC has grown to more than 1,000 IT experts across 11 offices in nine countries and reports experience supporting over 1,200 digital commerce projects worldwide. This scale enables the company to manage complex website redesigns involving multiple markets, platforms, data sources, customer journeys, and operational systems while keeping business growth and measurable outcomes at the centre of the project.

Highlights

• A redesign is more than a visual refresh: It should address user journeys, content structure, mobile usability, performance, conversion, SEO, security, and business-system integrations.
• SEO protection must begin before development: URL mapping, content auditing, redirects, metadata, internal links, and technical testing should be planned before the new site launches.
• The right partner depends on project complexity: Smaller agencies may suit focused branding websites, while enterprises may require experienced teams capable of handling multiple markets, platforms, integrations, security requirements, and long-term optimisation.

Why Website Redesign Matters in 2026

A website may need redesigning when its technology, content, visual identity, or customer journeys no longer support the organisation’s commercial and operational goals. Problems such as slow performance, confusing navigation, outdated information, weak mobile usability, or disconnected business systems can reduce customer trust, lead generation, and online revenue. This is especially important because Webflow’s 2025 survey of 500 enterprise marketing leaders found that 91% considered their website a greater revenue driver than any other marketing channel. A redesign should therefore be considered a strategic business investment rather than a purely visual update. Common warning signs include:

• Slow loading and unstable page elements
• Poor performance on mobile devices
• Difficult navigation or product discovery
• Low conversion or lead-generation rates
• Outdated branding and content
• Inaccessible design
• Complicated content management
• Security vulnerabilities
• Limited integrations with CRM, ERP, payment, or marketing systems
• Declining organic visibility following years of technical changes

In 2026, website performance should be assessed using real customer behaviour rather than appearance alone. Google’s current Core Web Vitals focus on loading performance through Largest Contentful Paint, responsiveness through Interaction to Next Paint, and visual stability through Cumulative Layout Shift.

A successful redesign should therefore make the website easier to use, easier to manage, faster to operate, and more capable of supporting future growth.

What Should Website Redesign Services Include?

Professional website redesign services should cover the complete website lifecycle rather than focusing only on new layouts.

Website and Performance Audit

• Traffic and conversion data
• Customer behaviour
• Navigation and information architecture
• Mobile usability
• Page speed
• Content quality
• Search rankings and backlinks
• Forms and conversion journeys
• Platform limitations
• Security and accessibility issues
• Third-party integrations

The audit creates a baseline against which the redesigned site can be measured.

UX Research and Journey Design

A redesign should be based on what users are trying to accomplish. Research may include analytics, interviews, surveys, heatmaps, session recordings, competitor analysis, and usability tests.

The team should identify priority journeys such as:

• Finding a product or service
• Comparing solutions
• Requesting a quotation
• Completing a purchase
• Booking an appointment
• Contacting support
• Accessing account information

These insights inform navigation, page hierarchy, content, and calls to action.

UI and Responsive Design

The new interface should present a consistent brand identity while remaining functional across mobile phones, tablets, laptops, and larger screens.

Important design considerations include:

• Clear visual hierarchy
• Readable typography
• Accessible colour contrast
• Consistent buttons and forms
• Responsive layouts
• Useful search and filters
• Simple navigation
• Trust signals
• Mobile-friendly interactions

Design decisions should support the user’s objective instead of adding decoration that slows down or complicates the experience.

Platform and CMS Modernisation

The existing content management system may no longer provide sufficient flexibility, security, or scalability. A redesign may therefore include migration to a more suitable CMS or commerce platform.

The organisation should assess:

• Content-editing workflows
• Roles and permissions
• Multilingual capabilities
• Personalisation
• Landing-page creation
• API support
• Security updates
• Integration compatibility
• Future expansion requirements

The objective is to give business teams greater control without creating excessive technical complexity.

Search Engine Optimisation

SEO should be integrated throughout the redesign. Important tasks include:

• Crawling and auditing the old website
• Preserving valuable pages and content
• Mapping old URLs to new destinations
• Maintaining relevant metadata
• Retaining internal links
• Reviewing structured data
• Updating XML sitemaps
• Testing canonical tags
• Checking robots.txt and indexing instructions
• Monitoring traffic and rankings after launch

Google recommends preparing a complete URL map and using permanent redirects when URLs change during a site migration. These steps help search engines understand where content has moved and reduce unnecessary disruption to organic performance.

Content Migration and Improvement

Moving every old page without review can carry outdated or duplicated information into the new site. Content should be classified as:

• Keep
• Improve
• Consolidate
• Redirect
• Remove

The redesign is also an opportunity to strengthen service pages, product information, FAQs, case studies, thought leadership, and conversion content.

Development, Security, and Integration

Development may include front-end and back-end work, CMS configuration, custom functionality, and integrations with:

• CRM platforms
• ERP systems
• Marketing automation
• Payment gateways
• Customer portals
• Product information systems
• Analytics platforms
• Customer-service tools
• Loyalty programmes

Security should cover access permissions, software updates, encrypted connections, secure development, backup procedures, and vulnerability testing.

Testing and Post-Launch Optimisation

Before launch, the team should complete:

• Functional testing
• Browser and device testing
• Mobile testing
• Performance testing
• Accessibility checks
• Form and payment testing
• Integration testing
• SEO validation
• User acceptance testing

After launch, businesses should monitor errors, customer behaviour, rankings, page performance, leads, conversions, and support requests.

How to Choose the Right Website Redesign Partner

Choosing among website redesign services requires more than comparing visual portfolios or selecting the lowest quotation. A redesign partner should understand how the website supports customer journeys, search visibility, content operations, integrations, security, and wider business objectives.

The right provider should also be capable of protecting the value of the existing website while addressing its limitations and applying best eCommerce website design practices where relevant. This includes retaining high-performing content, preserving important URLs, maintaining customer data, rebuilding integrations, and preparing internal teams to manage the new environment after launch.

Define the Business Objective

Begin by identifying what the redesign must improve:

• Lead generation: Increase qualified enquiries, quotation requests, consultations, registrations, or form completions.
• Online sales: Improve product discovery, conversion rates, average order value, checkout completion, and repeat purchases.
• Customer self-service: Allow customers to access documents, manage accounts, track orders, submit requests, or find support information independently.
• Brand credibility: Present a clearer value proposition, consistent visual identity, updated messaging, stronger trust signals, and relevant proof of expertise.
• Content management: Enable marketing and business teams to publish pages, campaigns, products, news, and resources without excessive developer support.
• Search visibility: Protect existing rankings while improving technical SEO, content quality, internal linking, structured data, and page performance.
• International expansion: Support multiple languages, countries, currencies, regional content, market-specific services, and scalable governance.
• Platform performance: Improve speed, reliability, security, mobile usability, scalability, and compatibility with future integrations.
• Employee productivity: Reduce manual content updates, duplicated data entry, fragmented systems, and repetitive customer-service tasks.

Clear objectives make it easier to evaluate proposals and measure results.

Review Relevant Case Studies

Look for projects with similarities in:

• Industry: A provider familiar with your sector may better understand customer expectations, terminology, regulations, and buying processes.
• Website type: Corporate websites, eCommerce stores, customer portals, marketplaces, content platforms, and financial-service websites have different requirements.
• Business size: A solution designed for a small business may not support enterprise governance, traffic, security, or integration needs.
• Technology platform: Review experience with the CMS, commerce platform, cloud environment, or development framework under consideration.
• Integration complexity: Relevant experience may include connecting CRM, ERP, PIM, OMS, payment, identity, analytics, or marketing platforms.
• Customer journey: Look for evidence that the provider has improved comparable activities such as product research, online purchasing, account management, appointment booking, or lead generation.
• Regulatory requirements: Industries such as banking, healthcare, insurance, and government may require additional controls involving accessibility, privacy, security, and content approval.

A beautiful project from an unrelated industry may not demonstrate the required technical or operational expertise.

Assess SEO Migration Experience

Ask the provider to explain:

• How the current website will be audited: The audit should identify important pages, organic landing pages, indexed URLs, backlinks, metadata, internal links, structured data, and existing technical issues.
• Who owns URL mapping: A named team member should decide which URLs remain unchanged, which pages are consolidated, and where removed content should redirect.
• How redirects will be tested: Redirects should lead users and search engines to the most relevant new destination without unnecessary chains or loops.
• How content and metadata will be preserved: Valuable copy, headings, titles, descriptions, schema markup, and internal links should not disappear during migration without evidence-based justification.
• How staging environments will be protected: Development and staging sites should not be indexed accidentally before launch.
• What will be monitored after launch: Monitoring should cover crawl errors, indexing, rankings, organic traffic, conversions, sitemap processing, redirects, and important landing pages.
• How recovery issues will be handled: The contract should explain who investigates and resolves migration-related SEO problems after launch.

SEO should have a named owner and dedicated pre-launch checklist.

Understand the Delivery Team

Confirm who will handle:

• Strategy: Defines objectives, priorities, scope, customer needs, and the transformation roadmap.
• Project management: Coordinates timelines, approvals, risks, dependencies, communication, and deliverables.
• UX research: Studies customer behaviour, pain points, journeys, accessibility needs, and usability.
• UI design: Creates visual interfaces, reusable components, responsive layouts, and the design system.
• Information architecture: Organises navigation, page hierarchy, taxonomies, URLs, and content relationships.
• Front-end development: Builds the customer-facing experience and ensures responsiveness, performance, and accessibility.
• Back-end development: Configures the platform, business logic, databases, APIs, and system integrations.
• SEO: Manages content preservation, technical requirements, redirects, metadata, and migration monitoring.
• Content: Audits, rewrites, restructures, migrates, and quality-checks website information.
• Quality assurance: Tests functions, browsers, devices, integrations, forms, performance, and user journeys.
• Security: Reviews access controls, software dependencies, data handling, vulnerabilities, and incident procedures.
• Analytics: Configures tracking, events, dashboards, consent settings, and measurement against business goals.

Avoid choosing a company without knowing which specialists will actually work on the project.

Compare Total Cost, Not Only the Initial Quote

The budget may need to cover:

• Discovery and stakeholder workshops
• Customer and competitor research
• Information architecture
• UX and UI design
• Front-end and back-end development
• Content auditing and rewriting
• Data and content migration
• CRM, ERP, payment, or marketing integrations
• Hosting and cloud infrastructure
• Security reviews and testing
• SEO migration
• Performance optimisation
• Accessibility testing
• Analytics configuration
• Staff training
• Post-launch support
• Software licences and extensions
• Ongoing maintenance
• Future updates and optimisation

A lower initial quotation may exclude important work that becomes expensive later.

Clarify Ownership and Support

The contract should define ownership of:

• Source code
• Website designs
• Written content
• Images and media
• Customer and transaction data
• Analytics accounts
• Tag-management accounts
• Hosting environments
• Domains and DNS settings
• App-store or platform accounts
• Technical documentation
• Integration credentials
• Infrastructure configuration
• Third-party licences
•  

It should also establish response times, warranty periods, maintenance responsibilities, and procedures for future changes.

A Practical Website Redesign Process

A successful website redesign requires more than creating new page layouts and replacing outdated visuals. It should follow a structured process that connects business objectives, customer needs, content, technology, SEO, security, and operational requirements. Clear stages also help teams control scope, manage risks, coordinate responsibilities, and measure whether the redesigned website delivers meaningful improvements.

A structured redesign normally follows these stages:

• Discovery: Define business goals, customers, scope, risks, budget, and success metrics.
• Audit: Analyse technology, content, UX, SEO, security, performance, and integrations.
• Research: Study users, competitors, analytics, search demand, and customer feedback.
• Information architecture: Plan navigation, page hierarchy, content relationships, and URLs.
• UX and UI design: Create wireframes, prototypes, responsive interfaces, and design systems.
• Development: Configure the platform, build templates, develop functions, and connect systems.
• Content and SEO migration: Move and improve content while preserving valuable search equity.
• Testing: Validate functionality, performance, accessibility, integrations, analytics, and SEO.
• Launch: Release the website with monitoring, backups, redirects, and support teams ready.
• Optimisation: Use behavioural and commercial data to improve the site continuously.

Common Website Redesign Mistakes

A website redesign can improve customer experience, performance, search visibility, and conversion, but poor planning can also create new technical and commercial problems. Many redesign failures happen when businesses focus too heavily on appearance while overlooking content, SEO, analytics, accessibility, integrations, and post-launch management. Avoiding the following mistakes can help protect existing performance and ensure the redesigned website supports long-term growth.

• Starting with visual design: The team should understand users, content, technology, and business goals before designing screens.
• Removing valuable pages without evidence: Old content may still generate traffic, backlinks, leads, or customer support value.
• Changing every URL unnecessarily: Excessive URL changes create avoidable migration risk.
• Ignoring mobile users: Responsive layouts must be tested on real devices and customer journeys.
• Migrating poor content unchanged: A redesign should improve unclear, duplicated, outdated, or low-value information.
• Adding too many plugins: Excessive extensions can reduce performance, security, and maintainability.
• Launching without analytics: Tracking should be configured and tested before the new site becomes public.
• Treating launch as completion: Websites require continuous security updates, testing, content improvement, and conversion optimisation.

A successful redesign should therefore be treated as a structured business and technology programme rather than a one-time design project. By auditing the existing website, protecting valuable content and SEO equity, testing critical journeys, and establishing clear post-launch ownership, organisations can reduce migration risks and create a website that continues to improve after launch.

SmartOSC Case Study: Sacombank Website Revamp

Sacombank’s existing website had an outdated interface, ineffective information presentation, and a user experience that was not properly optimised for its large mobile audience.

SmartOSC implemented a comprehensive redesign using Adobe Experience Manager. The project focused on compatibility across browsers and devices, faster access to information, improved content management, personalised experiences, forms, social integrations, microsites, and customer-behaviour tracking.

Following the transformation, Sacombank reported that website traffic doubled and website leads increased 2.5 times. The new environment also enabled the bank to use behavioural information to refine customer journeys and deliver more relevant content.

The project demonstrates how a redesign can improve not only appearance but also content operations, customer acquisition, personalisation, and measurable business performance.

FAQs: Website Redesign Services in Vietnam

1. How often should a business redesign its website?

There is no fixed schedule. A redesign is appropriate when the current site no longer supports user expectations, business objectives, security requirements, content operations, or technology integrations. Smaller improvements can often extend a website’s useful life without requiring a complete replacement.

2. How long does a website redesign take?

A focused business website may take several weeks or months. Enterprise websites involving research, content migration, multiple languages, complex integrations, security reviews, and approval processes usually require a longer phased programme. The timeline should be based on scope rather than a generic estimate.

3. Will a website redesign affect SEO rankings?

Rankings may fluctuate temporarily, particularly when URLs, content, internal links, or page structures change. A carefully managed migration can reduce the risk by preserving important content, mapping URLs, implementing permanent redirects, validating technical SEO, and monitoring the site after launch.

4. Should content be rewritten during the redesign?

Important content should be reviewed rather than automatically transferred. Rewriting is useful when pages are outdated, repetitive, poorly structured, misaligned with search intent, or unable to communicate the current value proposition clearly.

5. How can a business measure redesign success?

Metrics should reflect the project’s original objectives. Relevant measures may include organic traffic, qualified leads, conversion rate, revenue, page speed, task completion, engagement, customer satisfaction, support requests, content-publishing time, and website maintenance costs.

Conclusion

Professional website redesign services can transform an outdated website into a faster, clearer, more secure, and more commercially effective digital experience. The strongest projects combine customer research, UX, content, SEO, development, integrations, testing, and continuous optimisation.

For organisations with complex platforms or enterprise requirements, SmartOSC provides strategy, experience design, application development, digital commerce, cloud, Data & AI, and systems integration within one transformation approach. The Sacombank project demonstrates how this model can improve mobile experience, personalisation, traffic, and lead generation.
