The Challenge Coefficient, a B2B SaaS company that brings live business data into Google Sheets, was already running strong Google Ads campaigns. But they knew there was room to improve. They needed a fresh perspective from experts in B2B SaaS advertising—that’s where InterTeam came in. During our audit, we uncovered a number of issues including: $25K spent on ineffective age demographics (18-24 & 65+) $21K wasted on lower-income thresholds $15K misallocated to “optimized targeting”
Solution
Improved Segmentation and Ad Copy: Expanded from two ad groups to 10-20 per campaign, increasing ad relevance and reducing CPCs and CPLs. Smarter Retargeting: Built over 350 custom audiences to focus on high-intent users while excluding low-value segments. Omnichannel Expansion: Launched YouTube, Responsive Display, Demand Generation, and HTML5 ads to increase reach. Fixed Conversion Tracking: Collaborated with Google Ads and Coefficient’s developers to accurately track key down-funnel events
Result
The strategies that we implemented were highly successful and resulted in the following numbers: 2x weekly conversions 633 free trial sign-ups (Sept 2024 - Jan 2025) 132 tracked app installations Sometimes, small but strategic adjustments can unlock substantial growth.

Celayix offers a workforce management solution for companies in healthcare, security, and hospitality. Their platform simplifies workforce management by streamlining shift scheduling, time and attendance tracking, and enhancing communication between supervisors and staff. However, despite offering a powerful workforce management solution and hiring an advertising service, Celayix wasn’t generating quality leads.
Solution
First, we audited Celayix’s accounts, identified high-converting keywords and audience segments from the old campaigns and targeted them in our own campaigns. Then, we created ad campaigns on Bing, LinkedIn, and Google, targeting people in each vertical and searching for keywords with industry specific language. Once these were done, we focused on building retargeting campaigns for who viewed the demo or pricing pages on LinkedIn, Google and YouTube.
Result
Since partnering with InterTeam in January, Celayix's advertising performance has seen significant improvements: 160% increase in conversions 218% increase in conversion rates 25% increase in marketing qualified leads Want a second opinion on your ad campaigns?

Rise Vision offers cloud-based digital signage software that empowers organizations to create, manage, and deploy content across multiple digital displays. Their paid ad accounts weren’t performing well, so they asked us to look and see if any improvements could be made. We found that they had spent over $10,000 only to get a handful of free trials and a single lead. The numbers were way too low.
Solution
We reviewed their campaign performance and actually found that basically all of their conversions had come from only a handful of communities. These communities were highly relevant to Rise Visions service, either being specific to digital signage or groups for people who had relevant job titles like system admins. We created audiences on Reddit for visitors prioritizing more recent website visitors, created new exclusion audiences and tweaked their conversion tracking.
Result
By conducting a thorough review of Rise Vision’s accounts, InterTeam was able to uncover inefficiencies and eliminate thousands of dollars in ad spend. Our new strategies that we launched based on the audit resulted in significantly higher account performance. Here are some of our numbers: Increased their ROAS by 6x Reduced the cost per free trial by 63% Reduced the cost per lead by 77% Struggling to see returns on your ad campaigns?

Madison Brook International was facing high customer acquisition costs (CAC) and inconsistent lead generation through its PPC campaigns. Their goal was to increase visibility, generate quality leads, and reduce CAC.
Solution
We focused heavily on Quality Score, decreasing CPC and improving Ad Rank, which reduced lost impression share (more traffic, less cost). We refined keywords & bids, optimised ads, and adjusted audience targeting for better-quality conversions, with continuous A/B testing for ongoing improvements.
Result
Our strategy led to a +45% increase in click-through rates (CTR), a +35% reduction in cost per conversion, and a +40% increase in conversion rate. These changes significantly boosted their lead quality and reduced their overall marketing spend.
