How Strategic SEO Supported Growth Across 20+ Offices and 40+ Countries
We help construction and consultancy firms turn organic search into their strongest and most reliable source of qualified opportunities. Our focus is on building scalable SEO and digital strategies that work across multiple offices, markets, and countries without losing local relevance.
Company
Overview
This client is one of the leading construction consultancy firms in the United States, with offices in more than 20 states and active projects in over 40 countries. Our relationship began with a smaller San Diego-based consultancy whose digital marketing we managed prior to its merger into the larger organization. After the merger, the new leadership chose to keep us on as their digital partner, asking us to oversee the domain consolidation and provide ongoing SEO and broader digital strategy for the combined company.
The Challenge
After the merger, the new organization needed a digital strategy that matched its scale. Multiple offices and a broader international footprint had to be reflected in a single web presence without losing momentum in search. At the same time, leadership was highly focused on growing overall traffic and engagement, which meant consolidating domains and then building sustainable organic growth in key U.S. cities and global markets.
The strategy
We treated this as an enterprise SEO and authority-building project, focused on making one consolidated site work harder across many locations and markets. Our role was to guide the domain migration, strengthening the technical and authority foundation and making sure key cities and service areas were properly represented so organic search could scale with the business.
- Guided the migration from the smaller consultancy’s domain into the parent company’s site, preserving as much existing SEO equity as possible
- Audited the new site’s structure and on-page SEO across core construction consultancy services to align with enterprise search demand
- Planned and launched city-focused pages for priority markets such as Los Angeles, Boston, San Diego, and New York to capture local and “near me” searches
- Implemented a sustained, quality-focused link building program to better match the firm’s real-world authority with its backlink profile
- Advised on content structure so service pages, case studies, and thought-leadership pieces reinforced each other rather than competing
- Monitored organic rankings, traffic, and engagement in tools like GA4 and Ahrefs to track progress across locations and service lines
- Pivoted toward stronger local visibility by refreshing and expanding Google Business Profile listings for key U.S. offices
- Continued to refine targeting and internal linking as the firm’s footprint and focus evolved across states and international markets
Results
Over time, the combined strategy turned organic search into the client’s dominant acquisition channel. Rankings for priority U.S. cities such as Los Angeles, Boston, San Diego, and New York moved into far stronger positions, with many high-value consultancy terms now appearing on page one and in the top group of results. Ahrefs shows a clear lift in authority, with Domain Rating in the low 50s, 1.1K+ referring domains, and an upward trend in estimated organic traffic and AI citations across tools like Google AI Overview and ChatGPT. In a focused campaign window, this translated into 134,000+ organic visitors and 100,000+ direct visitors, reflecting both stronger discovery and more people seeking the brand out by name.
GA4 data backs this up: out of more than 1.3 million sessions in the reporting period, roughly 925,000 came from organic search, accounting for around 68% of all traffic and the majority of key events. Organic users viewed more pages and generated most of the meaningful engagement, confirming that the growth is tied to relevant searches and high-intent visitors rather than surface-level visibility. Those visitors supported seven-figure client acquisitions and new government contracts, while the improved visibility lowered future acquisition costs (CAC).
Traffic and engagement growth
GA4 shows that organic search has become the clear workhorse channel for this site, delivering just over 925,000 sessions out of roughly 1.3 million total in the measured period, nearly 70% of all traffic. Compared with other channels, organic visitors consistently showed stronger engagement, confirming that the growth in search wasn’t just bigger numbers, but better-quality visits.

Conclusion
This case shows how a large construction consultancy can use strategic enterprise-level SEO to turn a complex multi-office web presence into a dependable growth channel. By strengthening the authority profile and gradually improving local signals via GBP, organic search grew into the primary driver of traffic and engagement. The combination of strong organic share and healthier authority metrics indicates a durable foundation that can support future growth across new offices, markets, and service lines.
