A parallel-channel test to a live Google Search account that delivered 27% lower CPL and £2.31M in advisory assets for a UK IFA on a £1,227/month budget.
A chartered UK IFA firm specialising in pension consolidation for the 55-plus market was already running a mature Google Search account with Platinum Prospects, delivering a stable £85 CPL.
The firm wanted to diversify beyond a single paid-search platform and test whether Microsoft Ads could deliver meaningful incremental volume without cannibalising Google performance.
Microsoft Ads is often dismissed by UK advisers as "too small to matter", with ~8% of UK search share against Google's 92%. The challenge was to run a rigorous 90-day test that either validated Microsoft as a peer channel or produced the data to rule it out for good.
The test had to isolate Microsoft performance without contaminating the live Google account, maintain FCA-compliant creative across both platforms, and prove out audience quality - not just CPC.
A 90-day parallel test against the existing Google Search account, engineered to measure incremental lift, not replacement.
Imported the top 3 converting Google Search campaigns using Microsoft's Import from Google Ads tool, preserving ad group structure and negative keyword lists
Set initial Microsoft bids at 75% of the Google equivalent to reflect the less-competitive auction; let 21-day data inform ongoing bid adjustments
Deployed UET (Universal Event Tracking) with identical conversion names to Google, so reporting could be compared line-for-line in the client dashboard
Used Microsoft Audience Network for LinkedIn-profile-signal retargeting of pension-page visitors aged 55+ who did not convert on first visit
Created Microsoft-specific responsive search ads that referenced Edge and Outlook audience behaviours (desktop-heavy, long-form enquiry forms)
Identical campaign structures, identical FCA-compliant creative, measured over the same 6-month window.
Microsoft Ads is not a Google replacement - it is a Google complement. Run side-by-side, it adds roughly 45% more paid-search volume at a 27% lower CPL and delivers older, higher-net-worth pension enquiries. For UK advisers with a mature Google account, it is typically the highest-ROI incremental channel available.
We run Microsoft Ads as a peer channel alongside Google, Meta and LinkedIn for UK regulated firms. Audit your current paid-search stack and see where Microsoft could close the gap.
