A website redesign checklist exists for one reason: redesigns do not usually fail because the new design looks bad. They fail because something important from the old site — rankings, a working form, an indexed page — quietly breaks during the switch and nobody notices until traffic drops.
This website redesign checklist covers what to do before, during, and after a redesign, in the order it actually needs to happen.
Before You Start — Planning
- Write down the actual goal of the redesign — better conversions, updated branding, mobile performance, or all three — since this decides what changes and what stays the same
- List every page on the current site and mark which ones are actually getting traffic, using Google Analytics
- Decide what content is being kept, rewritten, or removed entirely before design work starts, not after
Audit the Current Site
- Export a full list of current URLs — every one that has ever been indexed, not just the ones in the current menu
- Check Google Search Console for which pages currently bring in real search traffic
- Note current page speed and Core Web Vitals scores as a baseline to compare against after launch
Protect Your SEO During the Switch
This is the step most redesigns get wrong, and it is the most expensive mistake to fix afterward.
- Set up a 301 redirect for every old URL that is changing, mapped one to one to its new equivalent — never redirect everything to the homepage
- Keep the same page titles and meta descriptions unless there is a specific reason to change them
- Preserve heading structure and internal linking patterns on pages that already rank well
- Update the XML sitemap and resubmit it in Google Search Console after launch
Content Checklist
- Confirm every piece of content from the old site has a home on the new site, even if it moved to a different URL
- Update thin or outdated pages while already restructuring, rather than carrying old problems into the new design
- Check that all images have alt text and are not oversized files slowing down the new pages
Testing Before Launch
- Test every form, checkout flow, and CTA button on the new design before it goes live, not after
- Check the site on real mobile devices, not just a desktop browser resized smaller
- Test on Chrome, Firefox, and Safari — small layout issues often only show up on one browser
- Run the new pages through Google PageSpeed Insights and fix anything scoring significantly worse than the old site
After Launch
- Monitor Google Search Console daily for the first two weeks for crawl errors or a sudden drop in indexed pages
- Check that analytics tracking is actually firing correctly on the new site before trusting any of its data
- Compare rankings for important keywords against the pre-launch baseline at the two-week and six-week marks
- Keep the old site backup accessible for at least a month in case something needs to be recovered
Common Mistakes That Cause Traffic Drops
- Redirecting every old URL to the homepage instead of its actual new equivalent — Google treats this as losing the original page, not moving it, and the ranking is usually lost along with it
- Changing page titles and headings for no real reason — a page that already ranks well for its current title rarely benefits from a rewrite done purely for the redesign
- Skipping a staging environment — testing changes directly on the live site risks visitors seeing a half-finished redesign, or losing content during the switch
- Launching on a Friday afternoon — if something breaks, there is far less time to catch and fix it before a weekend of lost enquiries
How Long Should This Take?
A straightforward redesign of a small business website usually takes 3 to 6 weeks from planning to launch. Larger sites with more pages, or ones needing significant content rework, can take 2 to 3 months. Rushing the SEO-protection and testing steps to hit an arbitrary launch date is the single most common cause of post-redesign traffic drops, and it is almost always avoidable with a realistic timeline set from the start.
