I’ve noticed that the cost-per-click (CPC) is increasing across most industries, and I’m sure you’re observing the same. Let’s dive into what’s causing this trend and explore strategies to safeguard your profit margins.
According to WordStream by LocaliQ’s 2025 benchmarks, nearly 87% of industries saw their CPCs rise year-over-year. The average CPC for Google Ads across sectors is now at $5.26 per click. In high-intent verticals, such as legal services, the average is $8.58, with some competitive B2B segments reaching $8 to $9 per click.
These increases reflect significant shifts in the design of search results pages, the optimization of auctions, and inefficiencies that accumulate across paid search accounts. Often, these issues remain hidden until a detailed PPC audit brings them to light. To begin reclaiming your budget, especially your branded terms, you need to understand the current landscape.
Here are the five trends every advertiser needs to grasp at this moment.
What’s Driving Your CPC?
More Advertisers Are Chasing the Same Limited Inventory
At its core, search advertising is an auction. As more advertisers target the same keywords, prices naturally increase. While global PPC spending continues to rise (Quantumrun Research), the number of available click slots on search results pages hasn’t expanded at the same pace. This results in higher CPCs, as more money competes for limited inventory.
The pandemic has had a permanent effect on this shift. Brands that previously didn’t invest in paid search have now joined Google’s auction and have stayed active.
Google’s AI Overviews Are Taking Over
Over the past decade, one of the most significant changes in paid search is happening right within the Search Engine Results Page (SERP). Google’s AI Overviews now dominate the space for informational and exploratory questions. As they grow into 2024 and 2025, they diminish the number of organic and paid listings visible above the fold.
A late-2025 analysis by Seer Interactive, reviewing 3,119 search terms across 42 organizations, revealed that the paid click-through rate (CTR) on queries with AI Overviews declined by 68%—from 19.7% to 6.34%.
The straightforward mechanism is that AI Overviews take more real estate (Skai), reducing the number of visible paid placements above the fold. As a result, impression share tightens, and automated bidding becomes more aggressive, driving up prices.
The important detail here is that users who navigate beyond an AI Overview tend to be further in their purchasing journey. WordStream data indicates approximately 65% of industries experienced higher conversion rates despite the increase in CPCs. This suggests the need to shift budgets toward high-intent transactional queries where AI Overviews are less likely to dominate, and away from informational queries where they are prevalent.
Smart Bidding Is Raising Auction Costs
Modern Google Ads campaigns more heavily rely on automated bidding strategies like maximizing conversions or targeting CPA. According to Google’s Smart Bidding documentation, the system precisely sets bids for each auction based on predicted conversion chances, prioritizing performance over cost control.
As almost every competitor utilizes the same logic, there’s a self-reinforcing loop of rising bid pressure, a market-wide dynamic that you need to adapt to rather than reverse.
Unauthorized Brand Bidding Is Inflating Costs Internally
Although platform algorithms and macroeconomics are beyond your control, one significant driver of CPC inflation is something you can manage.
When affiliates, partners, or competitors bid on your trademarked keywords, they enter an auction that should have minimal competition. Each additional bidder elevates your branded CPC, making you pay twice: once to create the demand, and again when third parties capture that same searcher at the bottom of the funnel.
The impacts accumulate. AI Overviews have already condensed available click inventory; unauthorized brand bidding further inflates the inventory cost you actually secure.
Detecting violations goes beyond manual SERP checks. Unauthorized bidders frequently use cloaking—geotargeting away from your headquarters or dayparting outside business hours—to evade detection. With a platform like Bluepear, you can implement automated 24/7 monitoring across search engines, geographies, and devices, capturing ad copy and landing page evidence to contest invalid affiliate commissions and enforce trademark guidelines at scale. Fewer bidders on your branded terms mean less auction pressure and lower CPCs for traffic you rightfully own. It’s one of the few paid search levers that doesn’t need a comprehensive strategic overhaul to be effective.
What To Do About It: Three Priorities for Advertisers
The gathered data indicates three clear priorities as you navigate this environment:
- Protect your branded baseline. Your branded keywords represent demand you’ve already generated. Rigorously monitor competitors in those auctions and eliminate unauthorized bidders with automated brand protection tools—an essential high-leverage action at present.
- Anchor optimization to cost per acquisition. Based on WordStream’s 2025 benchmarks, higher CPCs can bring a higher-quality, further-down-funnel user, leading to a lower CPA. The headline CPC figure is becoming an unreliable measure for campaign health.
- Build first-party data infrastructure. The best defense against continued CPC inflation is leveraging high-quality, proprietary conversion signals for your bidding algorithms, thus minimizing reliance on the platform’s broad audience approximations.
Average CPCs are reaching new heights and this trend is unlikely to reverse. Advertisers who effectively manage costs have already adjusted their strategies in response.
