Redesigning your website or moving to a new domain can be a positive step for your business. A new design can improve the user experience, make your services easier to understand and help convert more visitors into enquiries. However, if the transition is not managed properly, you could lose valuable SEO progress that has taken months or years to build.
The risk is not necessarily the new website itself. Problems often arise when URLs change, existing pages disappear, redirects are overlooked or important SEO settings are lost during development. Google needs to understand how the new website relates to the old one, and customers need to be able to find the information they previously relied on.
If you are planning a website redesign, changing your domain or moving to a different content management system, here is what you need to consider before making the switch.
Why Website Changes Can Affect Your Google Rankings
Google builds an understanding of your website by crawling its pages, following links and assessing the content and other signals associated with each URL. When you make significant changes, Google may need to recrawl the site and process the updated information before its search results reflect the new setup.
Some fluctuations during this process are normal, particularly after a large migration. However, substantial or prolonged ranking losses can occur when important information is removed or Google cannot correctly identify where old pages have moved.
For example, imagine your business has a service page that consistently ranks for a valuable search term and generates enquiries every month. During a redesign, that page is removed because the new website has a simplified menu. If the old URL now returns a 404 error and there is no relevant replacement, you could lose the search visibility associated with that page.
The same issue can occur when a developer changes URLs without setting up redirects, replaces detailed service content with generic copy or accidentally blocks search engines from accessing the new website.
These are avoidable problems, but preventing them requires SEO to be considered throughout the project rather than added as an afterthought once the new site is live.
What Happens When You Change Your Domain Name?
Changing your domain requires additional care because Google must process the move from your existing web address to the new one.
For example, if your business moves from oldbusiness.com.au to newbusiness.com.au, Google needs to discover the new URLs and understand that they replace the corresponding pages on the old domain. Simply pointing the old domain at the new homepage is not enough to handle the migration properly.
Each important page should generally have a relevant destination on the new domain. A service page should redirect to its equivalent service page, a location page should point to the corresponding location page and useful blog content should retain an appropriate destination wherever possible.
This is usually handled through permanent server-side redirects, commonly 301 redirects. These tell browsers and search engines that a URL has moved permanently and help consolidate signals associated with the old address.
You should also update internal links, XML sitemaps and canonical tags to reference the new URLs. Google Search Console can help you monitor the transition, and Google’s Change of Address tool may be appropriate for a qualifying domain move.
Keep control of the old domain and maintain the redirects for at least a year. In practice, keeping them in place for as long as possible is preferable, particularly if other websites still link to the old URLs.
The SEO Checks to Complete Before Launch
A website migration is much easier to manage when you establish a clear record of the existing site before anything changes. This provides a reference point if rankings or traffic decline after launch.
Before the new website goes live, make sure you have addressed the following:
Record your existing performance. Review Google Search Console and Google Analytics to identify the pages attracting organic traffic, the search terms generating impressions and clicks, and the landing pages contributing to enquiries. This helps you prioritise the pages that matter most to the business.
Crawl the existing website. Identify important URLs, page titles, meta descriptions, headings, canonical tags, indexation settings and internal links. A crawl gives you a practical inventory of the existing site’s structure and helps reveal what needs to be retained or improved.
Map old URLs to new URLs. Prepare a redirect spreadsheet before launch, especially if the website structure or domain is changing. Every valuable URL should have a suitable destination. Avoid redirecting every old page to the homepage when a more relevant replacement exists.
Preserve valuable content. A redesign does not automatically require rewriting every page. Review existing content and retain the information that helps customers and supports search visibility. Improvements are worthwhile, but removing useful content simply to make the site shorter can undermine its performance.
Check technical SEO settings. Confirm that important pages are indexable, robots directives are correct, canonical tags point to the intended URLs and the XML sitemap contains the right pages. Development websites are often deliberately blocked from search engines, so make sure those restrictions are removed when the production site launches.
Test the new website before launch. Check navigation, forms, internal links, mobile usability, page loading and redirects. Test the site on the final domain and verify that important pages can be accessed without errors.
What to Do Immediately After Launch
Once the new website is live, the work is not finished. The first few weeks are an important period for checking whether the migration has been implemented correctly.
Start by crawling the new website and testing the redirect map. Check that old URLs lead to the correct destinations, that there are no unexpected 404 errors and that important pages are accessible to search engines.
Submit the updated XML sitemap through Google Search Console and monitor indexing, impressions, clicks and ranking changes. If you have changed domains, follow Google’s site move guidance and use the Change of Address tool where applicable.
Keep an eye on organic enquiries as well as traffic. A temporary reduction in clicks does not always mean the migration has failed, and an increase in traffic does not necessarily mean the new site is performing better commercially. Comparing the same periods and looking at individual landing pages will give you a clearer picture.
If visibility drops significantly, investigate the cause rather than immediately making widespread changes. Common issues include missing redirects, pages accidentally excluded from indexing, altered content, broken internal links and incorrect canonical tags. Resolving the underlying problem is generally more effective than making unrelated adjustments in the hope that rankings recover.
Should You Redesign Your Website if Your SEO Is Already Working?
If your current website generates consistent enquiries and performs well in Google, there is no reason to assume that a complete redesign will automatically improve results. It may be the right investment if the site is difficult to use, outdated, slow or poorly structured, but the decision should be based on clear business objectives.
In some cases, targeted improvements to the existing website can address the problems without introducing the additional risks and costs of a full rebuild. If a new website is necessary, involving an SEO specialist during planning and development can help protect existing visibility while creating opportunities for improvement.
The key is to treat your website as an ongoing business asset rather than simply a design project. Its content, technical structure and search visibility all contribute to its ability to generate enquiries.
