What is a Law Firm Website Migration? (And Why It's More Than a Redesign)
At its core, a website migration is any significant change to a site's location, platform, structure, content, or design that can impact search engine visibility. For law firms, understanding the specific nature of the planned migration is the first step in identifying the associated SEO risks and opportunities.
It is crucial to move beyond the simple concept of a "redesign" and recognise the underlying technical shifts that will dictate the project's success. Many firms experience significant drops in visibility post-migration, often because the process was treated as a simple design refresh rather than the intricate technical manoeuvre it truly is.
The Critical Reality
A website migration represents one of the most technically complex and high-stakes projects a law firm can undertake. Executed without a meticulous, SEO-centric plan, a migration can lead to catastrophic loss of search engine rankings and a sharp decline in organic traffic.

Common Types of Website Migration
Design and Structural Changes
The most common type, involving significant changes to code, UI, navigation, and internal linking structure. Risk: breaking internal links or harming page speed.
New Content Management System
Moving from older systems to modern platforms. Risk: the new CMS may handle technical SEO elements differently, leading to widespread errors.
Domain Name Change
Highest-risk migration involving transferring entire domain authority. Occurs during rebrands or acquisitions. A flawed redirect strategy can reset years of SEO progress.
Protocol Change (HTTP to HTTPS)
Standard security practice requiring site-wide 301 redirects to ensure all traffic and link equity pass to the secure version of the site.
Key Strategic Drivers for UK Law Firms in 2025
Viewing a website migration solely as a technical necessity is a missed opportunity. For forward-thinking law firms, it is a strategic business decision driven by the need to gain a Competitive Advantage, mitigate Reputational Risk, and achieve a strong Long-Term ROI.
The legal sector is undergoing a significant digital transformation, and a firm's website is no longer a static brochure but a critical piece of business infrastructure. The technology underpinning the site is becoming a direct reflection of the firm's modernity and operational sophistication.
Enhanced Performance
Google uses Core Web Vitals as a ranking factor. Older platforms often struggle with slow loading times, leading to higher bounce rates and lower rankings. Even a one-second delay can significantly reduce conversions.
Migration to a faster platform directly addresses performance issues, improving both SEO and client acquisition potential.
Superior Security
Traditional CMS platforms like WordPress are prime targets for cyberattacks through outdated plugins. For law firms handling sensitive client data, a security breach represents an existential reputational risk.
Modern, headless architectures reduce the attack surface, offering more secure and compliant foundations.
Marketing Agility
Legacy systems can be rigid, making it slow for marketing teams to launch new content, update service pages, or integrate new tools. This limits responsiveness to market changes.
Migration to flexible, composable platforms allows continuous improvements and faster market adaptation.
Future-Proofing
A strategic migration can free a firm from vendor lock-in. A headless approach decouples the front-end from back-end, allowing technology updates without complete rebuilds.
This adaptability ensures the website evolves with technology, protecting the initial investment.
The Pre-Migration Blueprint: Planning for SEO Success
Thorough and meticulous planning is the single most important factor in a successful website migration. Experience shows that 90% of migration failures stem from inadequate planning.
Define Clear Objectives and KPIs
Set SMART (Specific, Measurable, Achievable, Relevant, Time-bound) objectives that provide clear benchmarks for success beyond simply "launching a new website."
Comprehensive SEO & Content Audit
Create a complete benchmark of existing site performance to measure against post-launch and identify high-value assets that must be protected.
Assemble Migration Team & Timeline
Multi-disciplinary effort with clear roles and realistic 3-6 month timeline including 20% buffer for unexpected issues.
Step 1: Define Clear Objectives and KPIs
A migration plan that lacks clear, realistic, and measurable objectives is destined to fail. Before a single line of code is written, all stakeholders must agree on what the project is intended to accomplish.
Well-Defined Law Firm KPI Examples

Step 2: Comprehensive SEO & Content Audit
A migration cannot be planned in a vacuum. Create a comprehensive benchmark of existing site performance to measure against post-launch and identify high-value assets that must be protected at all costs.
Crawl Your Entire Site
Use Screaming Frog SEO Spider or Ahrefs Site Audit to generate complete list of URLs, title tags, meta descriptions, and on-page elements.
Benchmark Performance
Document current metrics using Google Search Console, Analytics, and Semrush including traffic, rankings, and backlink profile.
Content Quality Audit
Decide content fate: Keep high-performing pages, improve outdated content, consolidate similar topics, remove low-quality content.

Step 3: Assemble Your Migration Team & Timeline
A website migration is a multi-disciplinary effort requiring clear roles and realistic timelines. The core team should include:
SEO Strategist
Project lead for SEO tasks, audit, redirect plan, and post-launch monitoring
Project Manager
Coordinates all parties, manages timeline, ensures communication between stakeholders
Web Developers
Front-end and back-end developers responsible for building and implementing technical SEO
Content Team
Responsible for migrating, editing, and creating content for the new site
Senior Partner
Key decision-maker providing final sign-off and championing the project internally
Realistic Timeline
A complex law firm website migration requires 3-6 months for planning, development, testing, and launch. Include a 20% buffer for unexpected issues.
The Ultimate Law Firm Website Migration SEO Checklist
A detailed checklist breaks the migration process into three distinct phases—Pre-Launch, Launch Day, and Post-Launch—providing a clear and actionable project plan.
Phase | Task | Key Consideration / Tool | Status |
---|---|---|---|
Phase 1: Pre-Launch | Full Site Backup | Create complete backup of all website files and database. This is a non-negotiable safety net. | ☐ |
Set Up Staging Environment | Clone of live site for development and testing. Block from indexing via robots.txt or password protection. | ☐ | |
URL Mapping & Redirect Strategy | Map every old URL to corresponding new URL. Prioritise 1:1 match. Use 301 (permanent) redirects only. Document in shared spreadsheet. | ☐ | |
Content & Metadata Inventory | Crawl existing site (Screaming Frog). Finalise content plan (keep, improve, remove). Ensure all title tags and meta descriptions accounted for. | ☐ | |
Technical SEO Checks | Verify canonical tags, hreflang tags (multi-language sites), and schema markup correctly implemented on staging. | ☐ | |
Local SEO Asset Audit | CRITICAL: Document exact NAP information. Audit all major UK legal directories (Law Society, SRA) and Google Business Profile. | ☐ | |
Benchmark All KPIs | Final snapshot of key metrics: keyword rankings, organic traffic, site speed, conversion rates using GA, GSC, and Semrush. | ☐ | |
Phase 2: Launch Day | Implement 301 Redirects | Push entire redirect map live at same time as new site. Test sample redirects immediately to confirm working. | ☐ |
Update DNS Settings | Point domain's DNS records to new server. DNS propagation can take several hours to complete globally. | ☐ | |
Check robots.txt & Meta Tags | Ensure robots.txt not blocking crawlers (remove Disallow: /). Remove any sitewide noindex tags from staging. | ☐ | |
Submit New Sitemap | Generate new XML sitemap for new URL structure. Submit via Google Search Console Sitemaps report. | ☐ | |
Annotate Launch in GA4 | Create annotation in Google Analytics 4 marking exact migration date. Crucial for pre- and post-migration analysis. | ☐ | |
Phase 3: Post-Launch | Crawl the New Site | Run new crawl (Screaming Frog) immediately to find broken links (404s), server errors (5xx), redirect chains. | ☐ |
Monitor Search Console | Watch Coverage and Crawl Stats reports closely for error spikes or signs Google struggling to crawl/index. | ☐ | |
Check Keyword Rankings | Monitor benchmarked keywords daily for first week. Some volatility normal, sustained major drops need investigation. | ☐ | |
Review Analytics Data | Compare post-launch organic traffic, user engagement, conversion metrics against pre-launch benchmarks. | ☐ | |
Check Google Business Profile | Verify website link in GBP points to new site and local map pack visibility not negatively affected. | ☐ |
Avoiding Catastrophe: 11 Common Migration Pitfalls for Law Firms
Understanding the common failure points is the key to proactively preventing them. Each represents a critical control point where diligence and expertise can avert disaster.
A Flawed 301 Redirect Strategy
The single greatest cause of migration-related SEO failure. A 301 redirect tells search engines and browsers that a page has moved permanently, passing along most of its SEO value.
What it is:
Failing to redirect old URLs, using temporary (302) redirects instead of permanent (301s), or redirecting all pages to the homepage instead of their closest equivalent.
✓ Prevention: Create comprehensive URL map matching every old URL to relevant new one on 1:1 basis. Rigorously test on staging before implementation.
Forgetting Canonical Tags and 'noindex' Rules
These tags are direct instructions to search engines. A canonical tag tells Google which version of a page to index, preventing duplicate content issues.
What it is:
Accidentally leaving a sitewide noindex tag from staging environment on live site, making entire website invisible to Google.
✓ Prevention: First technical check on launch day should inspect live site's code and robots.txt to ensure no noindex directives where they shouldn't be.
Losing Critical Metadata
Title tags and meta descriptions are stored in database and easily overlooked during platform changes. They directly impact click-through rates from search results.
What it is:
Launching new site with generic or missing title tags and meta descriptions, as these elements are what users see on results page.
✓ Prevention: During pre-migration audit, crawl and export all existing metadata. Ensure clear process for importing into new CMS and verify on staging.
Neglecting Page Speed and Core Web Vitals
Migration should improve site performance, but new designs with large images or inefficient code often make sites slower, harming user experience and rankings.
What it is:
Launching new site slower than the old one, resulting in poor user experience and potentially lower rankings due to Google's Core Web Vitals emphasis.
✓ Prevention: Performance testing must be core part of development and QA process. Use Google PageSpeed Insights to test staging site.
Additional Critical Migration Pitfalls
Breaking Internal Linking Structure
Changing URL structures without updating internal links leads to broken links (404 errors) and can "orphan" important pages.
Content Accessibility Issues
Making important content inaccessible or removing valuable pages without proper redirects, losing accumulated SEO value.
Loss of Valuable External Links
Failing to redirect old URLs means external links pointing to them become dead links, losing referral traffic and authority.
Hosting and Server Configuration Problems
Poorly configured new hosting environment leading to slower load times, downtime, or server errors affecting rankings.
Unoptimised Images
Failing to properly optimise images for new platform, causing slower load times and poor user experience on mobile devices.
Ignoring Mobile Optimisation
New site not properly optimised for mobile devices, crucial since Google uses mobile-first indexing for all websites.
Coincidental Google Algorithm Update
Failing to account for possibility of Google algorithm update during migration period that can mask or amplify migration-related issues.
The Local SEO Imperative: Protecting Your Local Rankings (A UK Focus)
For any law firm, local search is the lifeblood of client acquisition. A migration cannot be successful if it damages the firm's local search visibility. This is the "missing chapter" in most generic migration guides.
Auditing and Preserving NAP Consistency
Google's local algorithm relies heavily on consistent business information across the web to validate a firm's location and legitimacy. When a website URL changes, it creates a discrepancy between the new site and hundreds of online directories listing the old URL.
The Challenge
Manually finding and updating every single citation can feel like a game of "digital whac-a-mole," as data aggregators can re-populate old information.
The Solution
A proactive approach is essential. Before migration, conduct audit to identify most important citations. For UK law firms, this list must include:

Managing Your Google Business Profile Through Migration
The Google Business Profile (GBP) is the single most important asset for local SEO. It powers the firm's appearance in Google Maps and local pack results. Mishandling the GBP update can cause a firm to disappear from these crucial placements.
Critical Timing
Do not change the website URL in your GBP profile before the new site is live and all redirects are fully functional. Changing it too early sends potential clients to a broken or staging site.
The Instruction
On launch day, immediately after confirming the new site is live and key redirects are working, log into the Google Business Profile dashboard and update the website field to the new homepage URL. This ensures minimal downtime and maintains data consistency with Google.

Schema Markup for UK Law Firms
Schema markup acts like "sticky notes" for search engines, helping them better understand content and context. For law firms, implementing LegalService and LocalBusiness schema becomes even more critical during migration.
The Goal
Explicitly tell Google and other search engines the firm's correct name, address, phone number, and—most importantly—the new website URL. This reinforces the new information and accelerates search engine understanding of the change.
JSON-LD Schema Example
{ "@context": "https://schema.org", "@type": "LegalService", "name": "Example Law Firm LLP", "image": "https://www.new-law-firm-url.co.uk/images/logo.png", "@id": "https://www.new-law-firm-url.co.uk/", "url": "https://www.new-law-firm-url.co.uk/", "telephone": "+44-20-7123-4567", "address": { "@type": "PostalAddress", "streetAddress": "123 Legal Lane", "addressLocality": "London", "postalCode": "EC1A 1AA", "addressCountry": "GB" }, "geo": { "@type": "GeoCoordinates", "latitude": 51.5187, "longitude": -0.1002 }, "openingHoursSpecification": { "@type": "OpeningHoursSpecification", "dayOfWeek": [ "Monday", "Tuesday", "Wednesday", "Thursday", "Friday" ], "opens": "09:00", "closes": "17:30" } }
Post-Migration: Monitoring, Analysis, and Continuous Improvement
The work is not finished on launch day. The post-migration phase is a critical period of monitoring and analysis to ensure the transition has been successful and to quickly identify and resolve any unforeseen issues.
Your First 30 Days: Key Metrics to Watch
Google Search Console
This is the primary diagnostic tool for identifying migration issues.
Coverage Report
Check daily for first week. Sudden spike in 404 errors, 5xx server errors, or redirect errors indicates critical problem with redirect map or server configuration.
Crawl Stats Report
Monitor to ensure Googlebot is actively and frequently crawling the new site. Drop in crawl rate could signal a problem.
Google Analytics (GA4)
This is where the business impact is measured.
Traffic Acquisition Report
Compare organic traffic levels in days and weeks after migration to pre-launch benchmark. Filter by landing page to see if key service pages have lost traffic.
Engagement > Pages Report
Look for significant drops in traffic to previously high-value pages. This can help pinpoint specific sections where redirects may have failed.
Troubleshooting Common Post-Launch Issues
"My rankings have dropped!"
Some keyword volatility is normal in the 2-3 months following a major migration as Google re-crawls and re-indexes the site. However, a sudden, sharp drop across the board is a red flag.
First step: Rule out critical technical errors. Double-check for any stray noindex tags and ensure robots.txt file is not blocking important sections of the site.
"I'm seeing a lot of 404 errors in Search Console."
This indicates that users and search engines are trying to access old URLs that have not been correctly redirected.
Use Coverage report in Search Console and site crawler to get list of all broken links. Prioritise fixing ones with most external links pointing to them or that previously received most traffic.
"My new site isn't showing up on Google at all."
This is the most severe issue and usually points to an indexing problem.
Check that site is verified in Google Search Console, sitemap has been submitted, and most importantly, that there are no noindex tags or robots.txt rules preventing Google from crawling and indexing.
Choosing Your Law Firm Migration Partner
Successfully navigating a law firm website migration requires sophisticated expertise, project management discipline, and deep understanding of the legal sector. The stakes are too high for a DIY approach.
The sheer number of critical details and the significant financial and reputational risks associated with failure mean that a DIY approach can be a perilous undertaking. While it is possible for an in-house team to manage a migration, the most prudent choice is often to partner with a specialist agency.
An experienced partner brings not only technical proficiency but also a proven methodology honed over many similar projects. They understand the "unique challenges and requirements of the legal profession" and can provide the dedicated expertise and resources needed to execute the project flawlessly.
Specialist Expertise
Look for agencies with specific expertise in the UK legal sector and a track record of successful law firm website migrations. This specialisation ensures understanding of SRA compliance, legal client psychology, and sector-specific technical requirements.
Proven Methodology
Experienced partners bring battle-tested processes and frameworks developed over multiple successful migrations. They anticipate common issues and have contingency plans for when things don't go according to plan.
Dedicated Resources
Specialist agencies can provide dedicated project teams with the specific skills needed for each phase of the migration, from SEO strategists to developers to project managers, ensuring nothing falls through the cracks.
Risk Mitigation
Professional agencies carry appropriate insurance and have established processes for handling issues when they arise. This investment in expertise is the best insurance against the potentially catastrophic costs of a migration gone wrong.

Get Your Migration Strategy ConsultationWebsite Migration Frequently Asked Questions
Common questions and concerns law firms have when considering a website migration project and the associated SEO implications.
How long should I expect a law firm website migration to take?
A complex law firm website migration is not a matter of weeks. A realistic timeline of 3-6 months should be expected for planning, development, testing, and launch. This includes comprehensive auditing, strategic planning, development time, rigorous testing, and implementation. The timeline should include a 20% buffer to accommodate unexpected issues that invariably arise in projects of this scale and complexity.
Will I lose my search rankings during the migration?
Some keyword volatility is normal in the 2-3 months following a major migration as Google re-crawls and re-indexes the site. However, with proper planning and execution - including comprehensive 301 redirects, maintained content quality, and technical SEO best practices - ranking drops should be minimal and temporary. The goal is not just to maintain rankings but to improve them through enhanced site performance and user experience.
Do I need to update all my local directory listings after migration?
Yes, absolutely. When a website URL changes, it creates discrepancies between the new site and the hundreds of online directories that still list the old URL. For UK law firms, priority updates must include The Law Society's Find a Solicitor, the SRA register, Chambers and Partners, The Legal 500, and major local business directories. A plan must be in place to update these profiles on launch day to maintain local SEO consistency.
What's the biggest mistake law firms make during website migrations?
The biggest mistake is treating migration as simply a design refresh rather than the complex technical project it truly is. This leads to inadequate planning, particularly around URL mapping and 301 redirects. A flawed redirect strategy is the single greatest cause of migration-related SEO failure. Other common mistakes include accidentally leaving staging environment settings live (like noindex tags), losing critical metadata, and failing to account for local SEO citation updates.
Should we handle the migration internally or hire specialists?
While it's possible for an in-house team to manage a migration, the complexity and high stakes typically warrant specialist expertise. The investment in experienced professionals is insurance against potentially catastrophic costs of failure. Look for agencies with specific expertise in the UK legal sector and proven track records of successful law firm migrations. They understand SRA compliance requirements, legal client psychology, and the technical nuances specific to law firm websites.
How do I measure if the migration was successful?
Success is measured against the specific KPIs established during the planning phase. Key metrics include maintained or improved keyword rankings, organic traffic levels, site performance scores (Core Web Vitals), conversion rates from organic traffic, and local search visibility. Technical success indicators include clean crawl reports in Google Search Console, proper redirect implementation, and maintained backlink equity. The first 30 days require intensive monitoring, with ongoing assessment over 3-6 months to evaluate full impact.
