How to redesign your website without losing your Google rankings
Dimitri · 10 min read
A new site should bring more leads, not fewer. Here is the inventory, redirect map and launch checklist we use to protect rankings through a redesign.
A redesign should make your website better at bringing in work. But we regularly meet Calgary business owners whose phones went quiet the month after a new site launched. The site looked great. The problem was invisible: old pages that used to rank had disappeared, and nobody told Google where they went. Redesigning a website without losing SEO comes down to making sure that never happens to you.
The good news is that keeping your rankings through a redesign is not mysterious. It is mostly careful bookkeeping. In this guide we walk through why redesigns lose traffic, how to build a content inventory and redirect map, what to check before and after launch, and what a normal recovery timeline looks like. We use this exact process on every Calgary website redesign we take on.
Why redesigns lose rankings
Google ranks pages, not websites. Each URL on your current site has built up its own signals over the years: links from other sites, a history of clicks, and a place in Google's index. When a redesign changes or removes that URL, those signals have nowhere to go unless you send them somewhere.
The stakes are real. In BrightEdge's 2019 channel research, organic search drove 53.3% of website traffic on average across industries. For a local service business, the share can be higher, because most new customers start with a Google search.
And rankings are not easy to win back. Ahrefs' 2023 study of about 14 billion pages found that 96.55% of pages get zero traffic from Google. If you have pages in the small group that actually earn search visits, they are worth protecting.
The five most common causes
URLs change with no redirects./services/drain-cleaning/ becomes /drain-cleaning/ and the old one returns a 404.
Pages get cut. A designer trims "old" blog posts or location pages that were quietly bringing in leads.
Content gets thinner. A detailed 900-word service page becomes three bullet points and a stock photo.
Technical settings carry over from staging. A "discourage search engines" setting or a noindex tag goes live with the new site.
Titles, headings and internal links are rewritten without checking which keywords those pages ranked for.
Step 1: Take a complete content inventory
Before anyone opens a design tool, list every URL on your current site. This is the single most valuable hour in the whole project.
Where to pull URLs from
Google Search Console: the Pages (indexing) report and the Performance report, sorted by clicks.
Your analytics: top landing pages over the last 12 months.
A site crawler: to catch pages that are not linked in the menu.
Your XML sitemap and your CMS page list.
Backlink data: pages that other sites link to, even if they get little traffic.
Combine them into one spreadsheet. For each URL, record clicks, top queries, number of linking domains and a decision.
Decision
When to use it
What happens to the URL
Keep
The page ranks or converts and the URL is clean
Same URL, refreshed design, content kept or improved
Merge
Two or more thin pages cover the same topic
Combine into one stronger page; redirect the others to it
Move
The content stays but the URL needs to change
301 redirect from old URL to new URL
Rewrite
The topic matters but the page is weak
Keep the URL, improve the content
Retire
No traffic, no links, no business value
Redirect to the closest relevant page, or let it return 404 if there is truly no equivalent
A Kensington physiotherapy clinic, for example, might find that an old blog post about ski injuries brings in steady winter traffic every year. That page stays, even if it no longer fits the new look.
Step 2: Build a 301 redirect map
The redirect map is a simple two-column list: old URL, new URL. Every URL marked Move, Merge or Retire gets a row. Google is clear about the method: use a permanent server-side redirect whenever possible, meaning a 301 or 308 status code.
Redirect rules we follow
One hop, closest match. Redirect each old page to the most relevant new page, not to the homepage. Google's site move guidance notes Googlebot follows up to 10 hops, but ideally you keep chains under 3. We aim for one.
Server-side, not JavaScript. Google warns that JavaScript redirects depend on rendering, which can fail. Use them only if nothing else is possible.
Include variations. Old URLs with and without trailing slashes, http and https, www and non-www, and old PDF or image URLs that earned links.
Keep them for a long time. Google says to keep redirects in place for generally at least 1 year so signals can transfer. We simply leave them forever.

Step 3: Protect what made the old pages rank
Redirects carry signals across, but the new page still needs to deserve its ranking. When you rewrite or redesign a page, compare it against what the old page had.
Keep the topic and depth. If the old drain cleaning page answered pricing, process and emergency questions, the new page should too.
Keep or improve title tags and H1s for pages with strong rankings. Rewrite them deliberately, not by accident.
Keep internal links. Your menu, footer and in-text links tell Google which pages matter. A redesign that drops service pages from the main navigation can weaken them.
Keep structured data like LocalBusiness schema, and make sure your name, address and phone number match your Google Business Profile exactly. BrightLocal found that 56% of consumers check that business information matches across platforms, and Google notices inconsistencies too.
Keep it fast. A redesign is a chance to cut page weight, not add a heavy video background that slows phones down.
Step 4: Pre-launch and post-launch checklists
Here is the condensed version of the checklist we run. For the full version, see our website launch checklist.
When
Check
Why it matters
Before launch
Every URL in the inventory has a decision
Nothing important falls through the cracks
Before launch
Redirect map tested on staging
Catches typos and chains before Google sees them
Before launch
Titles, meta descriptions and H1s reviewed for top pages
Protects the pages that rank today
Before launch
Internal links point to final URLs, not redirects
Fewer hops, cleaner crawling
Before launch
Analytics and Search Console access confirmed
You cannot fix what you cannot measure
Launch day
Staging noindex and robots.txt blocks removed
The most common and most damaging mistake
Launch day
All redirects return 301 or 308, one hop
Signals transfer to the right pages
Launch day
New XML sitemap submitted in Search Console
Helps Google find the new URLs
Launch day
Forms, click-to-call links and booking tested on a phone
Leads keep flowing from minute one
Weeks 1 to 2
Search Console checked daily for 404s and indexing issues
Fix gaps before rankings slip
Weeks 1 to 6
Rankings and clicks for top pages compared with baseline
Spot problem pages early
Month 2 onward
Old sitemap removed, redirects left in place
Clean up without breaking anything
If you are also moving to a new domain, Google's guidance adds one more step: use the Change of Address tool in Search Console after your redirects are live.
What a normal recovery timeline looks like
Even a perfect migration causes some movement. Google says that you may experience ranking fluctuations while it recrawls and reindexes, and that for medium-sized sites it can take a few weeks or more for new URLs to replace old ones in results.

Here is roughly what we expect on a well-planned redesign for a typical 10 to 50 page service business site. This is our experience, not a guarantee, and every site is different.
Week 1: Google starts crawling the new URLs and following redirects. Small day-to-day swings are normal.
Weeks 2 to 6: Most old URLs are replaced by new ones in results. Rankings settle, sometimes a little lower for a short while.
Months 2 to 3: Traffic should be back to baseline. Improvements in speed, content and structure start to show.
Months 3 to 12: The new site should outperform the old one, especially if you keep adding useful content.
When to worry
A dip of 10 to 20 per cent for a week or two is usually just reprocessing. Investigate right away if traffic drops sharply and stays down after three or four weeks, if Search Console shows a spike in 404 or "excluded by noindex" pages, or if your top pages vanish from results entirely. Those signs almost always point to a technical mistake you can fix: a missing redirect, a leftover noindex tag or a blocked folder in robots.txt.
Redesigning in Calgary: timing tips
Timing your launch is worth a thought. Launch outside your busy season if you can. A landscaper or roofer will want to go live in late winter, not in the middle of May. An HVAC company in the NE might avoid the first cold snap of November, when furnace calls spike. A Stampede-season business in the Beltline should launch well before July. A quiet month gives Google time to settle and gives you time to watch the numbers.
It can, but it does not have to. Most ranking losses come from changed URLs without redirects, deleted pages that used to rank, or content that was cut. With a full content inventory, a redirect map and post-launch monitoring, most sites hold or improve their rankings.
02How long does it take Google to recognise a redesigned site?
Google says that for medium-sized sites it can take a few weeks or more for new URLs to replace old ones in results, and longer for large sites. Expect some ranking fluctuation in that period.
03How long should I keep 301 redirects?
Google recommends keeping redirects in place for generally at least one year so signals can transfer. We recommend leaving them in place indefinitely, since they cost almost nothing to keep.
04Do I need to change my URLs during a redesign?
Not always. If your current URLs are clean and descriptive, keeping them is the safest option. Change them only when there is a clear benefit, and redirect every old URL that changes.
05What should I check right after launch?
Test your redirects, confirm the site is not blocked from indexing, submit the new XML sitemap in Search Console, check forms and phone links, and watch Search Console and analytics daily for the first two weeks.
Planning a redesign? Start with what you already have
Before you change anything, find out what your current site is already doing for you. Your analytics and Search Console show which pages bring in traffic and leads, so you know exactly what to protect.
