CACI is one of the UK’s leading management consultancy and data companies, employing thousands of specialists across technology, data analytics, and business consulting. With a client base that spans government, retail, financial services, and the wider enterprise market, CACI is recognised as a trusted partner to some of the world’s most complex organisations.
As part of a major rebrand and digital transformation, CACI embarked on the launch of a new corporate website. With more than 11,000 legacy URLs and two recently acquired business sites to integrate, the challenge was to create a unified digital destination that could scale with the business. CACI needed a trusted SEO partner to safeguard visibility, traffic and lead generation, while ensuring a smooth migration from three fragmented sites into one.
When preparing to launch a newly branded website, CACI needed more than just technical SEO support. CACI required a trusted partner who could safeguard the visibility of a site that drives business across multiple sectors, while restructuring thousands of pages into a new, streamlined proposition.
The legacy CACI website had grown organically over time, resulting in complexity for both users and internal teams. Content spanned multiple templates, technologies and taxonomies, making the site difficult to manage and inconsistent in its presentation of CACI’s capabilities.
Adding to this challenge, two recently acquired businesses also needed to be folded into the new platform. Each of these acquisition sites had their own digital footprint, rankings and inbound visibility that needed to be preserved.
The project required:
Migrating 11,000+ legacy URLs alongside two acquired business sites.
Shifting from business unit–led navigation to a services and capabilities–led proposition.
Running digital performance audits on each acquired site to determine what should be migrated, consolidated or retired.
Retaining as much SEO equity as possible to safeguard rankings and traffic.
Maintaining business continuity across campaigns and lead generation during the transition.
1. Consultation & Digital Analysis
We began with a consultation to align SEO activity with CACI’s business goals for the relaunch. Alongside a full SEO audit of the legacy site, we conducted digital performance analyses of the two acquired websites. Rankings, traffic, and conversion data were benchmarked to determine the best strategy for consolidating their equity into the new domain.
2. Site Architecture & Restructuring
A new site architecture was designed around services, capabilities, datasets and software. Legacy categories were mapped to their closest equivalents, while content from the acquisition sites was rationalised and folded in to strengthen priority areas of the new proposition.
3. Content Migration & Equity Retention
Over 11,000 URLs were audited and mapped. Content from both the legacy CACI site and the acquired businesses was reviewed in partnership with CACI’s team, with priority content migrated to protect equity and weaker or duplicate pages consolidated.
4. Migration Management
POLARIS managed the full migration over 12 weeks, embedding SEO deliverables into the broader website launch plan. This included redirect mapping, QA testing, live changeover support and daily monitoring of traffic, rankings and user behaviour post-launch.
5. Campaign URL Continuity
To ensure cross-channel performance, we prioritised the migration of campaign-specific URLs from all three legacy sites, protecting active PPC, email and social campaigns from disruption.
“POLARIS are honest in their recommendations and always act in the client’s best interest. They deliver on their promises, and often go above and beyond to make sure objectives are met.”

Why It Matters
For a business of CACI’s scale, the website is not just a brand platform but a mission-critical channel for visibility, lead generation and client engagement. By managing the migration of three separate sites into one unified destination, POLARIS ensured CACI could evolve its digital proposition without losing momentum, protecting years of SEO investment while creating a platform for the future.
“Our technical capability is unmatched when guiding brands on large scale migrations. We enjoyed the challenge of folding 2 other business sites into the CACI brand. That was a great piece of work from the team."Amo SokhiManaging Director
