Website Redesign: 5 Mistakes to Avoid Before Redoing Your Site

Redesigning your website often seems like a good idea.

The design is outdated. The pages are too long. The site loads slowly. Competitors have a more modern image. Forms aren’t generating enough leads. The messaging no longer aligns with the offer.

In these cases, a website redesign can truly help.

But a redesign can also create major issues if it’s poorly prepared. A new site can look better but be less visible on Google. It can attract fewer leads. It can lose previous SEO rankings. It can also become harder to update on a daily basis.

That’s the paradox of many redesigns.

You want to improve the site, but you sometimes break what was already working.

A website redesign shouldn’t just be a design change. It’s a project that impacts SEO, content, UX, conversion, tools, and sometimes even your sales organization.

Here are the 5 mistakes to avoid before redoing your site.

‍

Why a website redesign can become risky

A website isn’t just a showcase.

For an SME, a small business, a freelancer, or a B2B company, it’s often a real acquisition channel. It presents your offer. It reassures your prospects. It captures leads. It builds your brand image. It can also support your organic SEO for several years.

When you launch a website redesign, you’re touching an important asset.

You can change the copy. The pages. The URLs. The menu. The forms. The CMS. The performance. The tracking. The blog content. The calls to action. The customer journeys.

Every change can have an impact.

That’s why a redesign must be framed before it begins. Not after the mockups. Not two days before launch. Before.

The right goal isn’t just to have a more modern site.

The right goal is to have a clearer, faster, better-ranked, easier-to-maintain, and more effective site for generating leads.

‍

Mistake 1: Redesigning without clarifying the business objective

This is the most common mistake.

A company launches a redesign because its site “no longer looks professional.” The observation is often correct. But it’s missing a key question: what result should the new site deliver?

Without a clear goal, a redesign quickly becomes a matter of opinion.

The executive likes one color. The salesperson prefers another section. The designer suggests an animation. The competitor has a page that looks interesting. Little by little, the site becomes a mix of ideas. Some are good. Others aren’t. But nothing truly guides the choices.

Before redesigning your site, you need to define its purpose.

Do you want to generate more quote requests? Get more appointment bookings? Better explain a complex offer? Reassure B2B prospects? Recruit? Sell online? Showcase client cases? Better convert SEO traffic?

The answer changes everything.

A site designed for appointment bookings isn’t built like an e-commerce site. A SaaS site isn’t built like a craftsman’s site. A local showcase site isn’t built like a national platform.

Design must therefore serve a purpose.

It must help visitors understand quickly. It must make the offer more readable. It must guide them to the right pages. It must reassure with proof. It must make action simple.

A beautiful page that leads nowhere remains a bad page.

Before talking design, ask these questions:

What is the site’s main message?

Which audience do we want to convince?

What action do we want to achieve?

Which pages should generate leads?

Which objections need to be addressed?

Which proof needs to be shown?

Only then does the mockup become useful.

At Scroll, this is a key principle in custom website projects. The agency doesn’t start with aesthetics alone. It connects design, UX, content, and conversion to your goals. Scroll notably presents its custom website service as a solution designed for conversion, with a UI/UX and Webflow team.

Mistake #2: Forgetting SEO before launch

A website redesign can improve your SEO.

It can make your pages clearer. It can fix a poor site structure. It can improve loading speed. It can enrich your content. It can create better service pages. It can also improve internal linking.

But it can also cause your traffic to drop.

The risk arises when SEO comes too late in the project.

For example, when the mockups are already approved. Or when the content is already finalized. Or when the old pages have already disappeared. Or when the new URLs are already ready without a redirection plan.

At that point, you try to fix things. But you’re no longer in control.

To avoid this, you need to conduct an SEO audit before the redesign.

This audit helps identify the pages that matter. Some pages already drive traffic. Others generate leads. Some have backlinks. Others rank for useful keywords. Even if your site seems outdated, it may contain valuable SEO assets.

Deleting them without analysis can be costly.

Before rebuilding your website, list the important pages. Check their rankings. Analyze their traffic. Review their conversions. Identify which content to keep, merge, or rewrite.

The goal isn’t to keep everything.

The goal is to avoid breaking what works.

You also need to prepare a new SEO structure. It should be easy for visitors and Google to understand. Service pages should be clearly named. Blog articles should be interconnected. Important pages should receive internal links.

The site hierarchy plays a central role here.

Scroll even has a dedicated article on website hierarchy. It explains how a clear structure helps organize pages, menus, user journeys, and the logic understood by Google.

A successful SEO redesign isn’t about copying the old site into a new design.

It’s about keeping the best of what exists and then building a stronger foundation for the future.

Mistake #3: Changing pages without preparing redirects

During a redesign, URLs often change.

An old page may disappear. A page may be renamed. Multiple pages may be merged. A new category may be created. The blog structure may change. The CMS may generate new paths.

All of this may seem technical.

But for your organic search performance, it’s critical.

A URL is an address. If you change it without notice, the old link may lead to a 404 error. Visitors land on a non-existent page. So does Google. External links pointing to that page lose some of their value. Old rankings may shift.

That’s why you need to prepare a redirection plan.

The principle is simple: every useful old URL should point to the closest new page.

An old service page should redirect to the new service page. An old article should redirect to the corresponding new article. A deleted page should redirect to a truly relevant page, not always to the homepage.

This is a point that many companies underestimate.

They think the redesign is complete once the new site is live. In reality, if redirects are poorly handled, the problems start right after launch.

A good redirect plan should be prepared before publication.

It should include old URLs, new URLs, redirect types, and the status of each page. Redirects must then be tested. You should also monitor 404 errors after going live.

It’s a step that’s not very visible, but highly valuable.

It protects your SEO traffic, backlinks, and visitor experience.

In a website redesign project, technical SEO isn’t a minor detail. It’s an insurance policy.

‍

Mistake #4: choosing a tool that’s hard to maintain

The choice of CMS or technology may seem secondary.

Yet, it influences everything that follows.

A site can look great at launch but become a hassle to manage after a few weeks. This is a real issue for small teams. If you need to call a developer to change text, create a landing page, or modify a form, the site will quickly become a bottleneck.

A website redesign must therefore factor in maintenance from the start.

Who will publish articles? Who will edit pages? Who will create landing pages? Who will update images? Who will track forms? Who will connect the site to the CRM? Who will fix minor bugs?

If no one can do these tasks easily, the site ages quickly.

The right tool depends on your needs.

Webflow is often suitable for a modern, fast, and easy-to-update showcase site. WordPress may work for certain editorial projects. Shopify can be logical for e-commerce. A no-code or low-code solution may be useful if you want to connect the site to business tools. Custom development may be necessary for very specific needs.

The goal isn’t to choose the most well-known tool.

The goal is to choose the tool your company can actually use.

Scroll specializes in these very areas: websites, web and mobile apps, no-code, AI, Webflow, Plasmic, n8n, Make, and automation. The agency also offers end-to-end support, from scoping to UX/UI design, through to SEO optimization.

On its Webflow Agency page, Scroll also details a methodology with scoping, UX/UI design, development, testing, launch, followed by monitoring and maintenance. This is exactly the kind of structure needed for a clean redesign.

A maintainable site lets you move faster.

You can test a new offer. Create a page for a campaign. Add a client case study. Modify a call-to-action. Publish an article. Adjust a page based on sales feedback.

This is where the redesign becomes useful in day-to-day operations.

Not just on launch day.

Mistake #5: Overlooking conversion and forms

A new website must be beautiful.

But above all, it must turn visitors into opportunities.

This is often where redesigns fall short. The design is cleaner. The pages are more modern. But inquiries don’t increase. Sometimes, they even drop.

Why?

Because conversion wasn’t considered.

A visitor won’t fill out a form just because the site looks nice. They do it because they understand the offer. Because they see the value. Because they feel reassured. Because the action is simple. Because they know what happens next.

Every key page must guide the visitor.

The homepage must quickly explain what you do. Service pages must answer concrete questions. Case studies must prove your credibility. Calls-to-action must be visible. Forms must be simple. Messages must be direct.

Too many sites hide their contact options.

The button is small. The form is long. The promise is vague. The visitor doesn’t know if they’re requesting a quote, an audit, a call, or just information.

The action needs to be clearer.

For example:

"Discuss my redesign"

"Request a website audit"

"Estimate my project"

"See if Webflow is right for my site"

These phrases are more concrete than a simple “Contact.”

Conversion also relies on proof.

Add case studies. Testimonials. Numbers. Examples. Screenshots. Logos. Results. Explanations of your process.

Scroll already highlights client case studies, including redesign and website projects. The case studies page features Côté Neuf as a website redesign aimed at modernizing the brand image, improving SEO, and automating real estate program management.

Finally, think about forms.

A form should collect enough information to qualify the request, but not so much that it discourages the visitor. It should also connect to your tools. For example, a request can be sent to a CRM, trigger a Slack notification, or initiate a follow-up email.

This is where automation can complement the redesign.

A good website doesn’t just receive leads.

It helps your team process them faster.

The right method for a successful website redesign

A successful redesign follows a simple logic.

Start by understanding the current site. Keep what works. Fix what’s broken. Then build a clearer foundation.

Before creating mockups, you need to frame the project.

Define the site’s main goal. Analyze existing pages. Conduct an SEO audit. List content to keep. Prepare the new sitemap. Choose the CMS. Write the content. Design the mockups. Develop the pages. Test the site. Set up redirects. Then track performance after launch.

It’s not more complicated than that.

But it must be done in the right order.

The biggest risk is starting with the visible part. Design gives the impression of progress. Yet, if the strategy, SEO, and conversion goals aren’t clear, the mockups may head in the wrong direction.

A website redesign must also plan for what comes next.

Once the site is live, you need to measure results. Is SEO traffic improving? Are forms working? Are visitors clicking the right buttons? Are service pages being visited? Are requests more qualified? Is the site easy to update?

This data allows for adjustments.

A website is never static. It must evolve with your offerings, customers, and priorities.

‍

Redesign your site, yes, but with a solid plan

A website redesign can be a great investment.

It can improve your brand image. It can boost your SEO. It can make your offer clearer. It can generate more leads. It can also make your team more self-sufficient day-to-day.

But it must be managed methodically.

The 5 mistakes to avoid are simple:

redesigning without a clear goal,

ignoring SEO,

change URLs without redirects,

choose a tool that’s hard to maintain,

neglect conversion.

If you avoid these pitfalls, your redesign will have a much higher chance of delivering real results.

At Scroll, we help businesses build modern, tailored websites designed for conversion. The agency combines UX/UI design, Webflow, no-code, automation, and AI to create clearer, more effective, and easier-to-evolve sites.
