WordPress Redesign: The 5 Common Mistakes Made by Agencies (and How to Avoid Them)

At Quebec WordPress, we confidentially support many web and marketing agencies in the technical execution of their WordPress projects. Among the most complex tasks we handle as subcontractors, WordPress site redesigns are by far the most common.

Why? Because redesigning seems simple… until it uncovers technical, SEO, or UX pitfalls that some agencies tend to underestimate due to a lack of specialized expertise.

Here are the 5 most common mistakes we observe — and, most importantly, how to avoid them to ensure the success of your client projects.

1. Failing to conduct an audit of the current site

It’s essential to carry out a comprehensive audit (technical, SEO, content, performance) before any redesign. However, agencies often skip this step and then face issues during the project such as:

  • An overloaded theme full of unnecessary modules
  • A slow site due to poorly optimized files
  • Poorly managed URL redirects harming SEO

Our solution: We systematically perform an audit during the planning phase. This allows us to properly assess the project and anticipate complexities.

2. Starting from scratch without preserving existing assets

Some projects begin with a “complete reset”: wiping everything out without considering the SEO history, reusable content, or existing 301 redirects.

Our solution: we review the content and performance to retain what already works. A redesign should be an improvement, not a break.

3. Choosing an inappropriate theme or page builder

To save time, some agencies favor overly bloated premium themes or misuse page builders (Elementor, Divi, etc.), which degrade performance and complicate maintenance.

Our advice: choose a lightweight custom theme or a page builder you master well. We create tailor-made templates optimized for speed, compatibility, and scalability.

4. Deploying without a staging environment

Too many projects are still launched directly on the live site, increasing risks such as downtime, visible bugs, and data loss.

👉 With us: every redesign goes through a staging environment to validate all developments without pressure.

5. Neglecting post-launch challenges

After the site is delivered, who takes care of security, updates, and backups? Many agencies finish their mission without providing a maintenance solution.

👉 Our support goes further: we offer a follow-up plan after delivery, including monitoring, automated backups, updates, and technical assistance.

Secure your redesigns with a reliable technical partner

Redesigning a WordPress site is not just about changing its appearance. It’s a strategic process impacting the client’s image, visibility, and performance.

At Quebec WordPress, we position ourselves as a partner to your team so you can focus on client relations and value creation. We ensure technical reliability with full transparency.
