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.

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.

Why choose Aventique as your website redesign agency

A redesign requires a high level of execution: a site can be visually successful but ineffective if it loads slowly, loses its SEO, or does not convert. Aventique positions itself as a partner capable of managing the whole process with a delivery-oriented approach.

You benefit from:

  • A clear method (audit → design → dev → migration → optimization);
  • An ability to manage redesign SEO challenges (mapping, redirects, indexing);
  • UX/UI work focused on conversion, not just design;
  • 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.

Do you offer maintenance after the redesign?
