320% Growth in Six Months: How FullSphere Made Microsoft Advertising a Core Performance Channel
March 20, 2026
Full Sphere’s structured rollout delivered measurable, scalable impact across its client portfolio. Within six months, the agency achieved a 320% increase in active Microsoft Advertising accounts, alongside a 32% lower average CPC compared to Google Ads across comparable campaigns. Between Q3 2023 and Q1 2024, this approach generated over 2,150 incremental conversions, with 70% of clients now actively incorporating Microsoft Advertising into their media mix. Notably, a finance-sector client saw a 410% uplift in leads compared to previous benchmarks. Together, these outcomes reflect not just isolated campaign success, but a sustained shift in adoption and performance across the agency’s client base.
FullSphere’s clients were heavily concentrated on Google Ads, facing increasing competition, rising CPCs, and limited incremental reach. The agency needed a scalable solution to expand audience reach, improve cost efficiency, and deliver stronger performance without increasing overall media spend.
FullSphere implemented a phased approach to introduce and scale Microsoft Advertising:
- Launched targeted pilot campaigns across select client accounts
- Tested creative, keyword strategies, and audience segmentation
- Leveraged Microsoft Audience Network to expand reach and engagement
- Optimized campaigns using automated bidding and performance insights
- Partnered closely with Microsoft Advertising for strategic guidance, reporting, and ongoing optimization
This disciplined approach ensured performance validation before expanding Microsoft Advertising across its broader client portfolio.
FullSphere achieved significant performance improvements and scalable adoption:
- 320% increase in Microsoft Advertising account adoption within six months
- 32% lower average CPC compared to Google Ads
- 2,150+ incremental conversions generated across client accounts
- 70% of FullSphere clients now actively invest in Microsoft Advertising
- Finance client achieved a 410% increase in lead volume
These results demonstrated Microsoft Advertising’s ability to deliver incremental, cost-efficient growth across diverse industries.
"Our focus is long-term, sustainable growth. Expanding into Microsoft Advertising has lowered overall acquisition costs while opening up additional high-intent demand, strengthening performance without increasing total spend.
Integrating Microsoft Advertising has reduced cost pressures while maintaining and often improving lead quality, with a 32% lower average CPC and exceptionally strong engagement from that traffic.
A key advantage has been LinkedIn Profile Targeting layered onto search. In competitive sectors like finance and professional services, this precision allows us to reach specific job titles, industries, and companies, putting our clients directly in front of decision-makers.
The result isn’t just cheaper clicks, but incremental, high-intent conversions. By diversifying the channel mix, we’ve generated over 2,150 additional conversions and scaled lead volume meaningfully, delivering a more efficient, higher-performing media strategy without increasing overall spend.”
