A website redesign is usually discussed in terms of appearance: colours, typefaces, new photography. Yet most problems that surface after launch have nothing to do with appearance — they come from the technical steps skipped during the move.
Below are the five mistakes we see most often in a redesign project, and what each one costs.
1. Going live without redirecting old URLs
This is the most expensive mistake. If page addresses changed in the new site and the old ones were never redirected, every page Google has known for years disappears at once.
The damage runs both ways: visitors arriving from search hit an empty page, and the value that page accumulated is not passed to its replacement. A months-long decline follows, and the cause is usually noticed far too late.
Before the redesign, the list of existing URLs must be exported, each one matched to its new equivalent, and the redirects switched on the day of launch.
2. Cutting the content
Text gets trimmed so the new design looks cleaner. It reads well visually, but the page weakens in search terms: questions it used to answer, it no longer answers.
If simplification is the goal, treat the visual layout and the amount of content as separate decisions. Placing the text more readably, rather than deleting it, solves both at once.
3. Leaving speed for later
"Let's launch first and look at speed afterwards" is said in most projects, and in most projects that "afterwards" never arrives.
Speed is part of the design: image sizes, how fonts load and the animated elements on the page must be planned from the start, or fixing them later means redesigning. Since the majority of visitors arrive on a phone, this translates directly into lost visitors. In our web design work we measure speed before handover.
4. Launching without measurement in place
The new site goes live, and a few weeks later someone asks whether it worked — with no data to answer. Search Console and analytics were never carried over during the move.
To be able to compare, the last three months of the old site's data should be saved, and measurement must be running on the day the new site launches. Skip this step and the success of the redesign stays a matter of opinion.
5. Removing local details from the page
For the sake of a clean design, the address, phone number and opening hours get squeezed into a small line at the bottom or baked into an image. Information inside an image cannot be read by a search engine.
For a business that wants to appear in city-based searches, these details must sit on the page as readable text. We cover how local search is built on our local SEO page.
Is a redesign really needed?
A new site is not the answer to every problem. If conversion is low, the cause may be the design, but more often it is elsewhere: the page is slow, unusable on a phone, or the visitor cannot find what they came for.
Measure the current site before deciding. How many visits does each page get, at which step do people leave, how long does it take to load on a phone? Once those three questions are answered, what usually emerges is targeted repair rather than a rebuild.
If a redesign genuinely is needed, that measurement is not wasted: it puts in writing what the new site must fix and leaves a baseline you can judge the project against.
Design and search must sit at the same table
Another common disconnect: the design is prepared by one team, then handed over with "do whatever SEO needs." Work in that order and decisions about heading structure, page hierarchy and URL layout have already been made — reversing them is expensive.
Heading structure is a good example. Text that looks large in the design but is not marked as a main heading in the code makes the search engine read the page's topic incorrectly. This can be fixed after the design is finished, but only page by page.
Deciding together is both cheaper and produces a sturdier result.
Frequently asked questions
Will my rankings drop after a redesign?
With redirects set up correctly there is a brief, small fluctuation and then recovery. Without redirects, the drop is permanent.
Should I move my old content to the new site?
Pages that receive search traffic must be moved. Check Search Console to see which pages get visits and decide from there; there is no need to insist on pages nobody visits.
Will my site be offline during the work?
In a properly run project, no. The new site is built at a separate address and goes live once approved.
How soon will I see results after a redesign?
Technical improvements read within weeks; changes driven by content and authority take months. Fluctuation in the first two weeks is normal and should not trigger a rollback.
Finally
A redesign is less about changing how the site looks and more about moving house. Making sure nothing is lost in transit takes more care than the new design itself.
