Website Redesign SEO Checklist: How to Protect Your Google Rankings

A website redesign should make it easier for customers to understand your business and enquire. But a new layout can also change the pages, links and information that helped those customers find you in the first place.

For a Gold Coast business that relies on searches for its services, SEO belongs in the redesign brief from day one. The aim is to improve the website while protecting its useful content and keeping a clear route from old pages to their replacements.

This website redesign SEO checklist covers what to record before the build, what to test before launch and what to monitor afterwards. It applies whether you are refreshing WordPress, switching platforms or commissioning a custom website.

The website redesign SEO checklist at a glance

Assign an owner to each row. A checklist is much more useful when someone is responsible for showing that each check passed.

1. Record what the current website already does well

Start with the pages that bring relevant visitors and enquiries, even if those pages look dated.

Google Search Console's Performance report shows clicks, impressions, click-through rate and average position. You can examine results by page, query, country and device. Export a baseline before the redesign so you have something concrete to compare with the new site.

Alongside that export, record the enquiries your existing analytics can reliably identify. Separate completed forms and bookings from button clicks: clicking a phone number does not tell you whether the call connected or became a customer.

For each priority page, note:

• The service or question it addresses.
• Its current URL, title and main heading.
• Useful details, photographs, FAQs and evidence worth retaining.
• The action a visitor should take next.

As a practical starting point, review the last three months and the equivalent period last year if available. Adjust the comparison for seasonal services, campaigns and changes in opening hours.

2. Decide which URLs actually need to change

A visual redesign does not automatically need a new URL structure. Keeping a useful page at its existing address can reduce the amount of migration work.

If URLs must change, give every important old page a deliberate destination. Google's site-move guidance recommends mapping old URLs to new ones and preparing the move before switching traffic.

For a hypothetical air-conditioning business, a planning sheet might look like this:

The destination should make sense to the person who followed the original link. Avoid treating the homepage as a universal replacement for unrelated deleted pages.

3. Test permanent redirects before customers need them

A redirect sends a visitor from an old address to a new one. For a permanent move, Google recommends a server-side permanent redirect where possible; both HTTP 301 and 308 are recognised. See Google's redirect documentation.

Ask your developer to test the actual old URLs, rather than simply confirm that a redirect plugin is installed. Each test should show:

• The old address redirects to the intended replacement.
• The replacement loads successfully.
• There is no loop or unnecessary sequence of intermediate pages.
• The visitor arrives at relevant content.

For site moves, Google advises keeping redirects for at least a year, and longer where practical. Include this in the handover so they are not removed during routine maintenance.

4. Keep the information customers came to find

Use the redesign to make important information easier to read. Before shortening a service page, check whether you are removing details that help a customer decide: scope, service area, process, exclusions, qualifications or answers to common questions.

For example, replacing a detailed service description with a large photograph and “Get in touch” may leave a prospective customer unsure whether you handle their job. Put the essential answer near the top, then organise supporting detail under clear headings.

Review every important page's title and description. Google recommends titles that are specific, concise and accurate; it may generate search snippets from page content or the meta description. Google's SEO Starter Guide explains these elements.

Give visitors a sensible next step through descriptive internal links. A service page can point to relevant work, a useful guide or an enquiry page. WDC's guide to website friction points that cost you leads explores the customer journey beyond the search result.

5. Check that the live site can be indexed

Development sites often need protection while work is unfinished. The launch check must distinguish those settings from what belongs on the public site.

A noindex instruction tells supporting search engines not to index a page. Check that it has been removed from the public pages you want in search, including any version set through HTTP headers. Also check that crawling is not unintentionally blocked. A robots.txt block is not a reliable substitute for noindex, because it can stop Google from seeing that instruction. Google explains the difference here.

Next, check canonical URLs: these indicate which version of a page you prefer search engines to treat as the main version. A rebuilt page should not accidentally point to a staging domain or an unrelated page. Google's canonical URL guidance explains how canonical annotations, redirects and sitemaps provide signals about preferred URLs.

6. Test the mobile enquiry journey

Open the live website on a phone and complete the same journey a customer would take: find a service, read the details, then enquire or book.

Check that text is readable, menus work, buttons are easy to reach and forms explain errors clearly. Submit a labelled test enquiry and confirm it arrives with the right team. Test booking integrations and confirmation messages too.

Review representative pages for loading speed and layout movement. Google's page-experience guidance covers mobile presentation, HTTPS, intrusive overlays and Core Web Vitals. A perfect performance score does not guarantee a top ranking, so use the findings to fix problems visitors actually encounter.

For businesses serving local customers, also verify that contact details and service-area information remain accurate. Our Gold Coast local SEO checklist covers that wider local presence.

7. Check the sitemap and inspect priority pages

Make sure the XML sitemap reflects the live pages you want search engines to discover. Check that it does not accidentally list development addresses or obsolete replacements. Submit it through Search Console where appropriate. A sitemap supports discovery; submission does not guarantee indexing. Google's sitemap guide explains the process.

Use Search Console's URL Inspection tool for priority pages. Its live test can help identify access and indexing problems in the current page, while the indexed report shows what Google has recorded. A successful live test does not mean the page is already indexed or guaranteed to appear in search.

8. Monitor enquiries as well as search traffic

Mark the launch date in your reporting. Compare priority pages with the baseline, rather than relying only on the site's total traffic.

A useful review separates three questions:

1. Are the intended pages accessible and being discovered?
2. Are relevant queries still producing impressions and clicks?
3. Are visitors completing the enquiries or bookings that matter?

As a working routine, check technical failures promptly after launch and review search trends weekly during the first month. This is a monitoring schedule, not a promise about recovery time. Google notes that significant changes can produce ranking fluctuations while it recrawls and reindexes a site.

If enquiries fall while relevant search traffic stays similar, examine the form, booking flow and tracking before assuming rankings are the problem. If specific pages lose visibility, investigate those pages and their replacements first.

Questions to ask before approving your redesign

Can a website redesign affect SEO?

Yes. Changes to content, URLs, links and indexing settings can affect how search engines understand the site. The checklist helps identify avoidable problems; it cannot guarantee unchanged rankings.

Do we need to change every page address?

No. Ask what each proposed URL change achieves. If the address still fits the content, retaining it may be the simplest option.

What should the agency hand over?

Request the URL map, redirect test results, a record of indexing checks, analytics access and confirmation that forms reach your team. Agree who monitors the launch and who fixes issues afterwards.

Plan the redesign around visibility and enquiries

A useful redesign brief connects the pages customers search for with the information and actions they need when they arrive. Keep the SEO checks, content decisions and enquiry tests in the same project plan.
