Website Redesign Services Without Losing Your SEO

Why do redesigns lose search traffic?

Most lost traffic after a redesign traces back to four decisions made without checking data. Addresses were changed without redirects, page titles and headings were rewritten for looks, content that ranked was cut as clutter, or the new build is slower than the old one. All four are avoidable, and all four are checked before launch in the method below.

What is the method?

It runs in order, and each stage hands a document to the next.

1. Audit. We combine a crawl, Search Console queries and pages, analytics landing pages and a speed test of your current site, so we know what earns clicks, links and enquiries.
2. Keep, change or kill inventory. Every page gets one of three labels, described in the table below.
3. Design on top of the inventory. Layouts are drawn around the pages that matter, not around a blank canvas.
4. Redirect map. Any address that changes gets one destination.
5. Speed budget. Targets are agreed before design is signed off.
6. Staging, review and a staged launch. Testing happens off the public web, then launch, then monitoring.

What does a keep, change or kill inventory look like?

The inventory is a shared spreadsheet you can open, argue with and change before anything is built. It is the single most useful thing a redesign produces.

How do you keep rankings through the move?

Google's site-move guidance gives the backbone: map every old URL to its new one, use permanent server-side redirects (301 or 308), send each old address straight to its final page rather than through a chain, and keep the redirects for at least a year. It also says not to point many unrelated old pages at the home page, because that can be treated as a soft 404. We follow all of it and add three habits of our own:

• Titles, meta descriptions, headings and structured data on pages labelled Keep are carried over unless there is a documented reason to change them.
• Internal links are updated to the new addresses so users and crawlers do not rely on redirects.
• If the design changes but the addresses do not, there is nothing to redirect, and the safest redesign is the one that touches the fewest URLs.

Some movement in rankings during recrawling is normal, and we cannot promise a particular result. What we can do is make the avoidable losses unlikely and watch the rest in Search Console.

What is a speed budget, and what should it be?

A speed budget is a written limit the new site must meet before launch, agreed while the design is still cheap to change. We build it on Google's Core Web Vitals: the good thresholds published on web.dev are Largest Contentful Paint within 2.5 seconds, Interaction to Next Paint of 200 milliseconds or less and Cumulative Layout Shift of 0.1 or less, measured at the 75th percentile of real page loads. We add limits on image weight, script count and font files, then test the staging site against them. If a design element breaks the budget, such as a full-screen video or an unoptimised slider, we flag it before it is built. Where the work is mostly speed, WordPress speed optimization is the more direct fit, and our article on how speed affects SEO and revenue explains why it matters.

What about content and accessibility?

A new design is a chance to fix text that has gone stale, but copy that ranks should not be rewritten for style alone. We rewrite pages labelled Change, keep the intent and main headings of those labelled Keep, and write short new copy where a template needs it. The accessibility pass covers colour contrast, heading order, form labels, focus states for keyboard users and meaningful image descriptions. It is practical, not a certification, and it also tends to improve usability for everyone on a phone.

How does a staged launch work?

The new site is built and tested on a private staging address with indexing blocked, so a half-finished site never appears in search. Before launch we confirm Search Console verification will carry over, check that nothing on the staging site blocks Googlebot after the switch, and, if DNS changes, lower the DNS cache time a week ahead, as Google recommends. On launch day the block is removed, redirects go live and the sitemap is resubmitted. We then review crawl errors, coverage and landing-page traffic over the following weeks and fix gaps as they appear.

Which platform should the redesign use?

Keep the platform you have unless it is the problem. A redesign on the same platform is cheaper, lower risk and keeps your content editors productive. If a platform change is justified, we build on WordPress, Shopify, Webflow or Wix, and design-to-code conversion covers cases where you already hold approved designs. Shopify sellers moving platforms should also read our page on Shopify migration.

What decides the price of a redesign?

We quote in writing and publish no package prices. The drivers are page and template count, how much content must be rewritten or migrated, the platform, integrations such as booking, CRM or checkout, custom design work compared with a template, accessibility requirements and the size of the redirect map. Use the cost estimator for a rough scope, then book a call to firm it up.

When should you not redesign?

Do not redesign because the site feels old if the real issue is somewhere else. If visitors arrive but do not enquire, a few targeted changes to the offer, forms and calls to action may do more, which is the work of conversion rate optimisation. If rankings are the issue, an SEO review may be the better first spend. If the site is slow because of plugins, fix the plugins. A redesign makes sense when the structure, brand or technology blocks what the business needs, or when changes have piled up until nothing fits.
