About

Trunk is an award-winning marketing agency that consults with professional services brands in competitive verticals. The agency crafts multi-channel PPC strategies, with Microsoft Advertising playing an increasingly important role alongside Google Ads.
We spoke to Trunk’s Senior Paid Search Manager, Jack Fletcher, who oversees search strategy and performance across all paid search accounts. “We partner with many leading B2B and professional services brands that rely heavily on paid search for customer acquisition. In competitive markets like that, diversifying beyond Google is essential.”

Why Microsoft Advertising?

Trunk’s increased investment in Microsoft Advertising wasn’t driven by curiosity or testing. It was a direct response to performance challenges, especially around lead quality and escalating costs on Google Ads.

We were struggling to hit the desired lead quality through Google Ads, especially as we tried to scale.

Microsoft Advertising offered a way to unlock incremental volume without simply paying more for the same results. “Google Ads costs were rising as we scaled spend. Microsoft Ads gave us an opportunity to expand without the same cost impact.” Jack shared with us 2 client examples where they had used Microsoft Advertising to improve performance: 

Case Study 1

Client objective


Reduce reliance on Google Ads while improving lead quality and cost efficiency for an insurance advertiser.

The challenge

Before launching Microsoft Advertising, the client was facing high CPLs and poor-quality leads. “CPLs were very high and lead quality was poor. We needed another channel that could deliver better-quality leads, not just more volume.”

What they did

Trunk launched Microsoft Search campaigns and later tested Performance Max, working closely with ClickTech to refine strategy and stabilise performance during the early learning period. “ClickTech offered us support through account audits, spend vouchers, and support calls to get the account into a position where the client was happy with the results.”

Results

Microsoft Advertising quickly proved its value as a scalable, high-quality channel. “Cost per lead came in at almost half the cost of Google Ads – and lead quality was higher too. Even when Microsoft Ads had higher CPLs in some cases, it consistently delivered the best lead quality.”

Case Study 2

Client objective


Aggressively grow market share by bidding for high-quality leads at scale.

The challenge

The client wanted to dominate their category, but needed confidence that increased investment would deliver efficiency not just volume. “The brief was to achieve large market share by bidding aggressively for high-quality leads.”

What they did

Trunk used performance data to identify the channels most capable of scaling efficiently, with Microsoft Advertising emerging as a key growth driver. Working closely with ClickTech and Microsoft, the team scaled activity with confidence. “Our data analysis enabled us to identify high-performing channels – with Microsoft being one of them – and ClickTech and Microsoft helped us achieve a strong CPA so we could scale aggressively.”

Results

Microsoft Advertising delivered standout efficiency compared to other platforms, helping drive performance that was recognised at an industry level. “We achieved a CPA on Microsoft that was 20–30% lower than the next best-performing channel, which was Google Ads.” This work contributed to Trunk winning European Paid Media Awards 2025 – Lead Gen Campaign of the Year for their “Recovery with Confidence” campaign for WRS.

The ClickTech Partnership

Beyond performance results, Trunk highlighted the practical value of the ClickTech Partner Program when introducing and scaling Microsoft Advertising with clients – particularly during early learning periods. “The biggest value we have got from the partnership is the spend vouchers. These vouchers have enabled us to retain clients on this channel through the learning period when results may be a bit volatile.”

The relationship was also described as genuinely collaborative, with direct access to ClickTech support – something the team sees as essential when encouraging clients to stick with Microsoft Advertising as campaigns mature. “Excellent – Ben, Niki and Alex have offered us brilliant support. Stick with the channel through the learning period and lean on ClickTech for advice and support.”
