CPC Inflation Starts Before the Auction: Why Paid Search Costs Are Rising

What Happened

Paid search costs are on the rise across almost every category, with the cross-industry average cost-per-click (CPC) more than doubling over the past decade. According to the latest WordStream benchmarks, the average CPC is now $5.42, a 14-18% increase year-over-year for Google Search and an 18-22% increase for LinkedIn. Some accounts are experiencing even higher inflation, with 25% increases in primary commercial keywords.

Key Details

• The number of advertisers participating in search auctions has risen 35% year-over-year due to AI creative tools lowering the barrier to entry for new bidders.
• AI Overviews are absorbing clicks that used to keep paid search efficient, leading to increased pressure on navigational and transactional traffic.
• The latest zero-click study from Sparktoro shows an 8% reduction in clicks through from search engines compared to 2025.
• Digiday's research with brand and agency professionals reveals that 37% of respondents have already seen informational search traffic decline.

What It Means For Your Business

The rising cost of paid search has significant implications for businesses trying to get found and cited by AI search. With fewer organic clicks reaching your site, you'll need to make up the gap in paid auctions, leading to higher CPCs and increased competition. To mitigate this, it's essential to focus on improving bids and ad copy, but also to explore opportunities outside the auction itself, such as:

• Optimizing your website for AI Overviews
• Increasing your brand's visibility through stronger marketing efforts
• Focusing on navigational and transactional traffic

Why This Matters For Your Business

In today's AI-driven search landscape, businesses need to adapt to the changing economics of paid search. By understanding the pre-auction dynamics driving CPC inflation, you can develop a more effective strategy to reach your target audience and stay ahead of the competition.
