Google Ads accounts have always been volatile beasts, but the changes we are seeing in some fundamental metrics suggest a significant shift in the costs of search advertising in 2026 – none more so than cost per click (CPC) and the impact of AI.
CPC inflation is like woodworm to your return on ad spend (ROAS). Without changing your media investment, your product or service pricing, or sometimes both, can send your profit and loss (P&L) heading in the wrong direction, sparking questions about the efficacy of digital advertising.
Despite CPC inflation, there is still no question that well-managed digital ad accounts are the most cost-effective lead and revenue generating channels that you can invest in. So, let’s have a look at the data and what you can do about Google Ads CPC inflation in your industry.
CPC inflation in numbers: Fewer clicks. Higher costs.
Dreamdata have published Google Ads B2B benchmarks for generic and search ads, and it makes for gloomy reading. In short, click-through rates (CTRs) are falling while CPCs are rising. The upshot? Budgets must work harder just to maintain similar levels of performance year on year. And I don’t know about you, but I’ve never seen commercial targets go down YoY.
Why is this happening?
A combination of factors sits behind these changes, with three key shifts in the search landscape over the last 12 months that stand out. The major drivers of CPC inflation that we are feeling now include:
1. The inventory squeeze
Google’s AI Overviews (SGE) have officially matured. By providing answers directly in the SERPs, the “above-the-fold” real estate for traditional ads has been compressed. We are all fighting for fewer high-CTR slots, and the auction price reflects that scarcity.
2. The Automation Paradox
Following the total sunsetting of Enhanced CPC last year, there is a higher reliance on Smart Bidding, a fully-automated system lacking in controls previously available. With more advertisers using “Maximize Conversions” algorithms, Google’s AI prioritises winning the auction over the efficiency of your campaigns. It’s a race to the top where the price to win is being reset by the highest-spending Smart Bidding bot on a regular basis.
3. The ‘Broad Match’ Tax
With the continued degradation of third-party cookies, Google has pushed Broad Match + Smart Bidding as the primary solution. This has widened the net, bringing new “accidental” competitors into niche auctions and driving up the baseline cost for everyone.
We are seeing these factors impact our clients to varying degrees, depending on which industry they are in, with some as high as 36% or even 40% YoY increases. Diligent management of the accounts and mitigating optimisations against the Broad Match Tax and the automation impact are key. There’s nothing we can do about the SERP changes.
Moving beyond the CPC to commercial metrics
As Head of Paid Media, my message to our partners and the wider industry is simple: CPC is not the data point that should be the focus.
Where previously CPCs were a cornerstone of successful account management, they are now just another data point/indicator of account performance that we must have in mind. Linking your media metrics to commercial outcomes must be the focus for successful search accounts in 2026 and beyond.
Understanding true ROAS, Lifetime Value of customers and what your profit is on purchases, leads (and clicks!) is far more important than simply what that click cost to generate. And yes, that means including agency fees and other costs contained in your ad spend.
This commercial detail is critical to enhance your understanding of how your campaigns are performing and what their value is. If a click in Leeds costs £7 and a click in London costs £12, but the London lead has a 40% higher retention rate, the “expensive” click is the bargain and well worth the initial investment. The agencies winning right now are the ones ignoring the “averages” and deploying budgets whilst considering the commercial outcomes of their spend.
The 2026 playbook
We cannot “optimise” our way out of a 30% market inflation using 2024 tactics. Success in 2026 requires:
- Aggressive negatives: Protecting your “Exact Match” islands from being swallowed by PMax and Broad Match.
- First-Party data as currency: Using your own customer data to tell the Google AI exactly which “expensive” clicks are worth the premium.
- Creative as the new lever: If the click is going to cost £4, the landing page experience and the ad copy should be doing 100% of the heavy lifting.
To sum up, the “Golden Age” of cheap traffic is over. The “Strategic Age” of Paid Media is just beginning.
Do you need an agency to help you prepare for CPC inflation?
Rising Google CPCs can be challenging, but with precision and smart strategy, it’s still possible to win. Highly focused campaigns, refined keywords and landing pages, and diversification across ad platforms can protect, and even boost, ROI despite CPC inflation.
