Website redesign can be one of the few projects that quietly unravel years of organic development in a matter of hours. The rankings that took an entire year and a half to achieve can decline in just a few days of a poorly managed website launch, not because Google is retaliating against the redesign, but due to some malfunction in the transfer process.
The difference between the old website and the new website is the area where a lot of problems arise in relation to enquiries for UK businesses using organic searches. This article looks at those SEO issues which businesses fail to consider when embarking on a website redesign project.
Does a website redesign affect SEO?
That’s right, and it works either way. A good design change that preserves the URL structure, implements the content migration, and boosts the page loading time usually results in improved rankings several months after launching the website. Conversely, poor planning may result in loss of previously acquired rankings due to incorrect redirects, unexpected merging of pages, and deletion of metadata.
It is not Google rating your new look but rather the Google bot re-crawling and re-indexing the whole site, which means that Google treats parts of the already created website as if they are completely new till it learns to trust them again. The companies who will successfully pass through the redesign phase are those that used SEO to create the site.
Common website redesign SEO mistakes
Most ranking drops after a redesign trace back to the same handful of errors:
- Changing URL structures without setting up 301 redirects from every old URL to its closest new equivalent
- Merging or deleting pages without first checking what they ranked for
- Forgetting to update the XML sitemap and resubmit it in Google Search Console
- Leaving staging-site noindex tags or robots.txt disallow rules live after launch
- Breaking the internal linking structure that pointed authority towards your best-performing pages
- Ignoring Core Web Vitals during the rebuild and shipping a slower site than before
- Dropping schema markup that took months to build reviews and rich data into
- Losing Google Analytics or Search Console continuity by relaunching under a new property instead of carrying the existing one across
Any one of these can cause a temporary dip on its own. Two or three together, on a site that draws meaningful traffic from organic search, can mean months of recovery rather than weeks.
Website redesign SEO checklist: before, during and after launch
Before you touch anything
- Audit and export every indexed URL, its current rankings and its backlinks before the old site comes down. This becomes your benchmark and your map
- Screenshot current traffic and ranking positions so there is something concrete to compare against later
- Map every old URL to its new equivalent, including pages you plan to merge or retire
- Keep the URL structure the same wherever there is no strong reason to change it
- Build the new site on staging behind a noindex tag and password protection so nothing gets crawled early
- If you have any control over timing, avoid launching in the run-up to your busiest trading period; Black Friday and the pre-Christmas weeks are the worst time to absorb even a short-lived dip
During the rebuild
- Build the complete 301 redirect map before launch, not after someone notices traffic has dropped
- Carry over existing meta titles, descriptions and heading structure unless you’re deliberately rewriting them for a clear reason
- Preserve or improve the internal links between your highest-value pages rather than leaving them to chance
- Keep or upgrade existing schema markup rather than dropping it from the new build
- Confirm your Google Analytics and Search Console properties carry over rather than launching under new ones, so historic data and conversion tracking do not fragment across two accounts
- Test page speed and Core Web Vitals on staging so problems get caught before launch, not discovered after
Launch day and the weeks after
- Upload the updated sitemap to Search Console right away after launching the website.
- Make sure you first spot-check all top pages on your site to see whether each one redirects properly.
- Take off all noindex tags or staging robot.txt right away after launching the site because failure to do so could deindex the entire site in silence.
- Check your Search Console coverage report daily for the first two weeks for any crawl issues or a sudden reduction in indexed pages.
- Monitor rankings and traffic once a week for eight to twelve weeks; a temporary decrease within the first few weeks is expected, but further decrease means there is probably a problem with a redirect or indexing.
Should you bring in an SEO-driven website redesign studio?
However, when the website consists of only a few pages, such a process might be sufficient for a safe redesign in-house. Otherwise, the case is different.
A website redesign agency based on SEO principles starts to consider migration from the first days of development and not vice versa, as it would be the case for any other website redesign studio. This usually translates into small things such as the creation of the redirect map alongside the sitemap and writing content briefs even before designing the first page.
In the case of extremely large websites, the gradual implementation of the new design is much more advantageous than switching the entire website in one day. It is much better to distribute the risk in such a way rather than destroy all the trust. In case organic traffic provides any revenue at all, it is usually worth paying for the redesign.
Treat SEO as part of the build, not an afterthought
Migrating SEO during a redesign is all about one thing: treating the migration as an integral part of your plan rather than as a clean-up process to be conducted after your site goes live.
It is not always the most sophisticated redesigned website that maintains its ranking; it is rather the websites where the migration was treated just as well as the redesign process.
FAQs
Yes, it does. This is because the URL, content, and technical aspects of the site will change during the process, and these are the main factors that are used by Google for its rankings. If done correctly, a redesign will actually help to improve the rankings of your site.
It typically takes four to eight weeks for SEO rankings to stabilize when the website migration process is done correctly, but it is also common to experience a drop in ranking during the first two to three weeks. Failure of traffic to recover within twelve weeks warrants an investigation into any missing redirects, unindexed pages, and missing internal links.
All URLs that have ranked, were externally linked, or experienced traffic must be redirected using the 301 status code to the URL on the new website that is most similar to the previous one. Redirecting all URLs to the home page instead gives much less value.
Yes, but the migration has to be planned rather than improvised. Maintaining URLs, planning redirects in advance, and monitoring Search Console rigorously over the following weeks are the three things that will keep the rankings intact.
Not auditing the ranking positions of the current website before the redesign. Such teams are prone to making designs based on looks rather than rankings and end up losing rankings on pages they did not know mattered.
