Enterprise search engine marketing
Delivering customer acquisition at scale for the financial services, insurance and not-for-profit sectors.
Who We Are
Enterprise search marketing where efficiency, consistency and scale matter.
Expansive Digital is a founder-led agency specialising in enterprise search engine marketing for the financial services, insurance and not-for-profit sectors. Based in Melbourne, we work with organisations across Australia and support their paid search activity across domestic and international markets. Clients work directly with Kham Tran, whose experience spans more than 24 years in the digital sector, including 21 years in paid search.
That combination of experience and sector knowledge helps us navigate competitive markets, connect the right audiences with our clients' products and services, and make informed decisions at scale. Our clients include ASX-listed companies and established national organisations, with some client relationships extending beyond five years.
We have extensive experience managing multimillion-dollar media budgets within complex, multi-account structures spanning Google Ads and Microsoft Advertising, including advanced cross-engine bidding through Search Ads 360. Whether managing established account portfolios or undertaking complete rebuilds and restructures, our focus is on improving customer acquisition performance and making more effective use of our clients' media investment.
Expansive Digital works with a small number of organisations at a time. We are not actively seeking to expand our client roster, although we may consider a new engagement where there is a strong strategic fit and a clear opportunity to deliver significant value. Previous clients are also welcome to get in touch about further support.
How We Work
With more than 24 years in digital, including 21 years working hands-on in paid search, we bring an uncommon depth of practical experience to every engagement. A genuine passion for the craft, data and complex challenges helps us understand accounts quickly, prioritise the right opportunities and begin improving performance without an extended learning period.
Our track record is built on strong, consistent performance and substantial efficiency gains over previous benchmarks. Full transparency is central to how we work. Campaign builds, optimisation changes and budget pacing reports are documented online and shared with clients, providing a detailed, up-to-date record of our work that they can review and query at any time.
Strong performance requires understanding more than the account itself. We take the time to learn each client's operating model, priorities and marketing activity, allowing us to work with the judgement and accountability expected of an experienced in-house team. Direct communication and responsiveness help us operate as a closely connected extension of that team.
What We Do
Structured for efficient customer acquisition, informed decision-making and performance that can scale as needs evolve.
We manage enterprise-level paid search activity across Google Ads and Microsoft Advertising, including multi-account environments and advanced cross-engine bidding through Search Ads 360. Our services include ongoing account management, strategic optimisation, and complete account rebuilds and restructures. The focus is on efficient customer acquisition, strong account fundamentals and performance that can scale as needs change.
Our performance approach extends to display advertising and Performance Max, with campaigns structured around clearly defined objectives for lead quality and volume, sales or transaction value. We use sophisticated audience, bidding and measurement strategies to identify incremental opportunities and scale performance, with the aim of outperforming previous benchmarks for both efficiency and growth.
We plan digital activity in the context of each client's wider marketing strategy, taking into account social media and YouTube, as well as television, radio and other traditional channels. This broader view helps inform campaign timing, messaging and investment. The aim is to improve overall marketing returns and support incremental growth, rather than focusing only on performance within the digital channels we manage.
