Website Redesign Cost: The 7 Things That Move the Price

Your site is five years old, it looks it, and someone on the team finally said the word redesign out loud. The first quote you get will be a single number, the second will be a different single number, and neither will explain why. The reason is that a redesign is not one product. It is seven decisions bundled together, and each one moves the price in a direction you can predict once you know what to look for. Here are the seven, in the order they usually show up in a proposal, followed by what must survive the project no matter which way you go.

1. Page count, and how many pages are actually different

Fifty pages is not fifty times the work of one page. What matters is the number of distinct templates: a homepage, a service page, a blog post, a contact page, a case study. Fifty service pages built on one template cost little more than five. Fifty pages that each have their own layout are fifty design problems, and they are quoted that way.

Before you ask for a quote, group your pages by shape. A spreadsheet with a column for template type tells an estimator more than the total count ever will, and it usually shrinks the number, because most sites have far fewer shapes than pages. Templates also decide what your team can build later without calling anyone.

2. Content migration: who moves what

Every existing page has text, images, PDFs and metadata that must end up somewhere on the new site. Somebody either moves it by hand, writes a script that moves it, or decides it will not be moved. All three cost something, and the third option is often the honest one for pages nobody has visited in two years.

The migration line in a quote is also where surprises hide. Ask whether it includes cleanup (broken images, formatting that only worked in the old theme, duplicate pages) or only the transfer. A clean transfer of messy content gives you the same mess in a new coat. Decide the fate of every page before the quote, and the migration line stops being a guess.

3. Design system or template

A template is a design somebody else made, adapted to your brand. A design system is a set of components designed around your content, your tone and your sales process, then used to build every page. The first is faster and needs less budget; the second is what you want when the site is your main sales channel and it has to look like nobody else.

The middle ground is a custom design on top of a proven component library, which is how most web development projects for growing companies are actually built. You get an original look without paying for the invention of a button. Ask which parts of the design will be original and which come from the library; a good answer names both.

4. Integrations and forms

A contact form that sends an email is a small task. A form that creates a CRM record, assigns it to a sales rep by territory, starts an email sequence and posts to Slack is an integration, and it is quoted as one. The same goes for booking widgets, payment links, newsletter tools, live chat and anything that has a login.

List every tool the current site talks to and every tool you wish it did. Each entry is a line in the estimate, and each one is a candidate for the question: does this need to exist on launch day, or can it arrive in month two? Deferring two of them rarely changes the launch and often changes the number.

5. SEO migration and redirects

This is the driver most often missing from low quotes, and the one that can cost you the most if it is skipped. Every old URL that changes needs a redirect to its new home, or the rankings and backlinks attached to it disappear. Title tags, meta descriptions, structured data, image alt text and the XML sitemap have to be carried across, and the analytics tags have to keep firing so the history stays comparable.

A redesign is also the moment to think about how the site reads to AI assistants, since they pull from the same structured content Google does; we covered that in AI search visibility. A quote that does not mention redirects has not thought about your rankings. Ask for the redirect map as a deliverable, in a spreadsheet you keep.

6. Performance and accessibility targets

A site that must load fast on a mid-range phone, pass Core Web Vitals and meet accessibility guidelines is built differently from one that only has to look good in a design review. Image pipelines, font loading, lazy loading, keyboard navigation, color contrast and screen-reader labels are all work, and they cost less to build in than to retrofit.

State the target in the brief. If you sell to government, healthcare or education buyers, accessibility is often a contractual requirement, and it belongs in the scope, not in a change request six weeks later. The same applies to speed: a target score on a named tool is a requirement, while a promise that the site will be fast is a hope.

7. Who writes the copy

Design cannot rescue a page with nothing to say. Somebody has to write the new headlines, service descriptions and calls to action, and that somebody is either you, a copywriter on the agency side, or a mix. Redesigns that assume the client will supply copy are the ones that run months late, because writing about your own company is harder than it looks.

Decide this before the quote. If the agency writes, the price goes up and the timeline holds. If you write, the price goes down and the timeline depends on you. Both are fine; the costly version is not deciding. A mixed model, where you supply the facts and the agency shapes them into copy, is usually the fastest of the three.

Refresh or rebuild, the brief, and comparing two proposals

Not every site needs to be torn down. A refresh keeps the platform and the structure and changes the visual layer: new typography, colors, imagery and a few reworked pages. A rebuild changes the platform, the structure or both. Refresh when the site works and looks dated; rebuild when it is slow, hard to edit, built on a platform nobody supports, or organized around a business you no longer run. Whichever you choose, three things must survive: the URLs (or a complete redirect map), the rankings that depend on them, and your analytics history. Losing any of the three turns a design project into a recovery project.

A brief that produces comparable quotes has the page inventory grouped by template, the list of integrations, the content plan (who writes, what migrates), the SEO requirements, performance and accessibility targets, and a launch date with the reason behind it. If your site sells directly, the e-commerce cost drivers add a layer on top of all of this.

When two proposals come back, do not compare totals first. Compare what each one says about redirects, copy, integrations and revision rounds. The one that lists exclusions is usually the more honest one. Then ask each firm the same question: what happens if we add three pages in month two? The answer tells you how the relationship will feel.
