Aventique, Website Redesign Agency
A website redesign is not just a “makeover.” It is a strategic project that impacts brand image, commercial efficiency, technical performance, SEO visibility, and often internal organization (content, tools, back-office, publishing processes). A successful redesign must be managed like a product project: starting from measurable objectives, auditing the existing site, designing a better experience, rebuilding the technical foundation, preparing the migration, then launching without loss (or with as little loss as possible) and improving post-launch.
Aventique is a website redesign agency that supports its clients from A to Z: scoping, UX/SEO audits, UI/UX design, development, integrations (CRM, forms, analytics), migration preparation, testing, production launch, then maintenance and evolutions. Our approach aims for a concrete result: a clearer, faster, more visible, and more efficient site for your users and your business.

Why redesign a website
The reasons for a redesign are often cumulative. A site may “work” but still hinder growth.
Common motivations:
- Improve conversion rate (contacts, quote requests, sales);
- Modernize the interface and strengthen brand credibility;
- Fix technical issues (slowness, security, instability, technical debt);
- Restructure the offer and clarify the brand message;
- Prepare for evolution (new CMS, new design system, headless, multi-language);
- Resolve SEO problems (traffic drop, indexing, duplication, inconsistent architecture);
- Make the site more autonomous (back-office, page templates, publication workflow).
A redesign is relevant when “small tweaks” are no longer enough, or when the current structure prevents reaching objectives.
What Aventique does for a website redesign
A redesign agency must master three dimensions simultaneously: experience (UX/UI), technology (development, performance, security), and visibility (SEO, tracking). Aventique intervenes throughout the entire cycle, with concrete deliverables at each phase.
Specifically, we perform:
- Audit of the existing site (UX, content, SEO, technical, performance);
- Definition of the redesign strategy (objectives, user journeys, architecture, priorities);
- UX/UI design (wireframes, mockups, prototyping);
- Web development (showcase site, CMS site, webapp, landing pages, components);
- Integrations (forms, CRM, marketing tools, analytics, tags);
- SEO migration (URLs, 301 redirects, canonicals, sitemaps, verifications);
- Testing and launch;
- Post-production monitoring (stabilization, corrections, optimizations);
- Maintenance (corrective, evolutionary, security).
Website Redesign: Our Step-by-Step Methodology
Scoping: Objectives, Scope, and Indicators
A redesign begins with clear alignment. Without scoping, you simply rebuild a “prettier” site without improving efficiency.
We define:
- Business objectives (leads, sales, recruitment, awareness);
- Targets and intent (who visits the site, to do what);
- Priority pages and user journeys;
- Constraints (CMS, hosting, internal tools, resources);
- Success KPIs (conversion, speed, SEO, engagement, forms, etc.);
- Planning and governance (follow-up points, validations, owners).
Recommended deliverable: A scoping document + a redesign roadmap (milestones, phases, dependencies).
SEO Audit: Securing the Redesign and Building the New Architecture
SEO is one of the major risks of a redesign. A poorly prepared migration can significantly degrade organic traffic.
We audit:
- Pages generating traffic and conversions (to preserve / improve);
- Queries and intent (what users are actually searching for);
- Current structure (depth, linking, orphan pages, duplication);
- Indexing (indexed pages, excluded pages, inconsistencies);
- Performance (weight, scripts, images, CWV if available);
- Content (quality, gaps, cannibalization, opportunities).
Deliverables:
- Conservation / optimization plan for strategic pages;
- Recommendations for new sitemap (pillar pages, service pages, local pages if needed, resources);
- List of pages to create, merge, delete, or redirect.
UX and Content Audit: Improving Understanding and Conversion
A redesign must improve user experience; otherwise, the ROI is limited.
We work on:
- Clarity of the value proposition;
- Information hierarchy (what is seen, when, and why);
- Friction in user journeys (from entry page to action);
- Consistency of messages by target audience;
- Editorial structure (headings, proof, reassurance, CTA);
- Mobile compliance (readability, buttons, forms, accessibility).
Recommended deliverable: UX diagnostic + journey recommendations + content plan (sections to add, pages to enrich).
UX/UI Design: Wireframes, Mockups, Design System
Design serves to validate journeys before development.
We produce:
- Wireframes (page structure, blocks, priorities);
- UI Mockups (branding, typography, components, states);
- Prototypes (rapid validation, iteration);
- Light design system (reusable components) if relevant.
Objective: Accelerate development, avoid discrepancies, and guarantee overall consistency.
Development: CMS, Custom, or Hybrid
Aventique adapts the solution to the context rather than imposing a default choice.
Typical cases:
- CMS-based redesign (WordPress, Webflow, others) for showcase or content sites;
- E-commerce redesign (Shopify, WooCommerce, others) based on needs;
- Custom redesign (front + back) when there is business logic, integrations, a specific back-office, or high requirements;
- Hybrid approach: CMS for content + custom components for critical parts.
We focus specifically on:
- Performance (image weight, loading, scripts, cache);
- Maintainability (structure, components, documentation);
- Security (updates, best practices);
- Editorial (page templates, fields, reusable blocks).
Tracking and Data: Measuring Before and After
A redesign must preserve the ability to measure and improve.
We secure:
- Analytics (GA4 or other), events, conversions;
- Tagging plan if necessary;
- Forms and CRM feedback (HubSpot, Salesforce, etc., depending on context);
- Marketing pixels (if used);
- Compliance (consent banners / CMP, if applicable).
Recommended deliverable: Tracking plan + post-launch compliance check.
Migration Preparation: The Heart of “SEO Risk”
This is often where success is decided.
We prepare:
- URL mapping (old → new);
- 301 redirects (no chains, no errors);
- Canonicalization rules;
- Management of deleted / merged pages;
- Sitemaps, robots.txt, meta directives;
- Internal link checking (avoid links to old URLs);
- Preparation of an SEO testing plan before and after launch.
Deliverables: Mapping file, redirect list, migration checklist.
Testing and Production Launch
Before going live:
- Functional testing (forms, CTAs, journeys);
- Responsive testing (mobile/tablet/desktop);
- Performance testing;
- SEO testing (indexability, tagging, redirects, canonicals, sitemaps);
- Tracking verification.
Launch:
- Launch window;
- Immediate controls (server errors, redirects, critical pages);
- Monitoring during the first few days.
Post-Launch Monitoring: Stabilize, then Optimize
The redesign doesn’t end at go-live. The best progress is often made in the following 4 to 8 weeks.
We track:
- Indexing and coverage;
- 404/500 errors, redirect anomalies;
- SEO variations (queries, pages, CTR);
- Real-world performance;
- User behavior (conversion, journeys, exit pages).
Then we iterate:
- Content optimizations;
- UX improvements;
- Semantic enrichments;
- New pages based on opportunities.

Depending on the scope, here are typical deliverables that Aventique provides (or co-produces with your teams):
- Scoping document (objectives, KPIs, scope, planning);
- SEO / UX / Technical audits (prioritized);
- Target sitemap + content plan;
- Wireframes + UI mockups + prototype;
- Development backlog/tickets;
- Templates and components (service pages, content pages, landing pages, etc.);
- URL mapping + redirects + migration checklist;
- Testing (functional + SEO + performance);
- Tracking plan + post-production verification;
- Post-launch monitoring + optimization plan.
How long does a website redesign take
Timelines vary based on:
- Number of pages and templates;
- UX/UI complexity;
- Technology (simple CMS vs custom);
- Migrations (languages, SEO, content, third-party tools);
- Team availability (validation, content).
Pragmatic benchmarks (indicative):
- “Simple” showcase redesign: A few weeks to 2–3 months;
- Redesign with significant content + SEO + several templates: 2–4 months;
- Redesign with custom work / integrations / multi-language: 3–6 months and more.
The most robust approach often consists of phase-based delivery: redesigning the core + priority pages, followed by extension.
How much does a redesign cost (and what determines the budget)
Main factors:
- Scope (pages, templates, features);
- UX/UI (design system, level of finish);
- Technology (CMS vs custom, integrations, security);
- SEO migration (URL volume, complexity, multilingual);
- Content (rewriting, creation, optimization);
- Maintenance and post-launch monitoring.
Aventique recommends a structured estimation by phases, with an MVP or a “refreshed core” if the situation allows. This secures the budget and accelerates the launch.

- Reliable technical execution (performance, maintainability, security);
- Post-launch support (stabilization, evolutions, maintenance).
FAQ - Website Redesign Agency
Does a redesign always cause SEO loss?
No, but the risk is real if the migration is poorly prepared. A redesign can also significantly improve SEO if the architecture, content, and performance are optimized, and if redirects are managed correctly.
Should I change CMS during a redesign?
Not necessarily. You change CMS if the current one hinders performance, editorial autonomy, security, or evolutions. Otherwise, a redesign can be carried out on the same CMS by improving structure and templates.
How to avoid a 'beautiful but ineffective' redesign?
By setting KPIs, auditing existing data, prioritizing journeys that convert, and measuring after launch (tracking + iterations).
Can Aventique handle content?
Yes, depending on your organization: recommendations, page plans, SEO optimization, or even production if the setup is planned. The goal is to have a coherent site, not a collection of mismatched pages.
