In the first quarter of 2025, advertisers shelled out more money on Google than ever before, yet the payoff in traffic and conversions didn’t keep pace. 

[New data](https://searchengineland.com/google-ad-spend-continues-outpace-traffic-volume-454452) from digital agency Tinuiti reveals a 9% year-over-year increase in Google Search ad spend, driven largely by rising cost-per-click rather than actual user engagement. 

While Microsoft Ads outperformed with a 17% spending increase, a deeper look into platform performance, competitive dynamics, and campaign strategies signals that the digital marketing landscape is shifting fast.

With clicks plateauing and returns diminishing, advertisers are asking whether paid search advertising is still effective.

## Behind the Spend

Marketers spent more on Google Search in Q1 2025, but didn’t necessarily get more for it. Tinuiti reports that while spending rose 9% compared to Q1 2024, click growth remained steady at 4%, and the average CPC increased by 5%. That means advertisers are paying more to reach audiences that aren’t growing at the same rate.

In Google Shopping, the picture is slightly more optimistic. Click volume rose 9%, a notable improvement from just 1% growth in Q4 2024, while spending rose 8%. 

Yet even here, results are mixed. CPCs barely moved, dipping by just 1%, and dominant players like Amazon, Walmart, and Target continued to capture the lion’s share of impressions. 

Amazon alone held a staggering 60% impression share, suggesting limited breathing room for smaller retailers.

And then there’s the wildcard: Temu, a fast-growing marketplace, abruptly vanished from Google Shopping ads in April after [U.S. tariff announcements](https://tinuiti.com/blog/marketing/tariff-landscape/). Its disappearance could have significant ripple effects across the platform in the months ahead.

## The PMax Problem

[PMax campaigns](https://www.stanventures.com/news/googles-performance-max-campaign-placement-rules-stir-confusion-1645/) were meant to usher in a new era of advertising automation. Instead, they’ve become a cautionary tale.

Despite an impressive 93% adoption rate among Google Shopping advertisers, PMax campaigns are underdelivering. Their share of ad spend fell from 69% in Q4 2024 to just 53% in Q1 2025—a steep decline in just three months. 

Performance metrics reveal a 13% higher CPC, 10% lower conversion rates, and a 7% drop in ROAS versus standard Shopping campaigns.

Marketers are responding by pulling back. Many are reallocating budgets toward traditional Shopping ads that offer greater transparency and control. 

Automation alone doesn’t guarantee performance. Without accountability, even the most advanced tools can fall short.

## Microsoft Steps In: A Quiet Contender Gains Ground

While Google remains the heavyweight, Microsoft Ads is quietly gaining ground—and gaining trust.

In Q1 2025, Microsoft Search Ads posted a robust 17% YoY increase in ad spend, more than doubling the 7% growth seen in Q4. 

Even more promising, click volume rose 5%, reversing a previous decline. 

CPCs rose 11%, but that increase was largely driven by higher demand, particularly for brand keywords, where costs surged 19%.

For marketers wary of Google’s diminishing returns, Microsoft is proving a worthy alternative. It offers a growing user base, competitive costs, and the chance to diversify beyond Google’s walled garden. 

As marketing teams look for smarter budget allocation, Microsoft’s momentum can no longer be ignored.

## Why Marketers Must Rethink Paid Search

Across platforms, marketers are spending more for slightly better results, forcing a recalibration of ad strategies in 2025.

Performance Max’s underperformance, rising CPCs, and stiff competition from dominant retailers are squeezing returns. 

Meanwhile, political developments, such as U.S. tariffs that forced Temu off the field, are proving that even top-performing campaigns can be derailed by forces outside a brand’s control.

Marketers need a new playbook. Gone are the days of blindly increasing spend and letting algorithms do the heavy lifting. 

In today’s climate, success comes from strategic planning, smarter testing, and platform diversification.

## Practical Moves for Smarter Search Advertising

Here are five actionable steps marketers can take right now to navigate rising costs, shifting platforms, and evolving campaign performance:

**Revisit your campaign mix.** If you’re still leaning heavily on Performance Max, now’s the time to reassess. Standard Shopping offers better performance and more control for many brands.

**Expand to Microsoft.** With growing reach and strong ROI, Microsoft Ads offers a solid alternative that shouldn’t be treated as an afterthought.

**Monitor macro changes.** Temu’s exit shows how tariffs, regulations, and global politics can 

suddenly reshape digital advertising. Stay alert and agile.

**Prioritize efficiency, not just spend.** More budget doesn’t guarantee results. Focus on conversion rates, ROAS, and customer lifetime value over vanity metrics like clicks.

**Leverage first-party data.** As automation struggles and CPCs climb, owning your data becomes your biggest competitive edge.

## Ad Spend Realities Mark a Turning Point for Search

Search advertising is no longer just about being present—it’s about being smart. Spending more doesn’t mean earning more, and automated tools like PMax, once considered game-changers, are revealing their limitations.

In response, the industry is recalibrating. Marketers are shifting to platforms that deliver better value, embracing manual campaign oversight, and demanding transparency from automated systems. Microsoft’s rise reflects this mood. So does the pivot back to standard Shopping campaigns.

The future of paid search won’t be won with the biggest budgets, but with the sharpest strategies. Those who evolve will thrive. Those who don’t risk paying more and getting less.
