Search Engine Land says CPC keeps rising across most industries, and AI-heavy SERPs are making paid clicks scarcer. For arbitrage teams, that makes weak intent targeting much more expensive.
According to Search Engine Land, citing WordStream by LocaliQ’s 2025 benchmarks, nearly 87% of industries saw year-over-year CPC increases, and the cross-industry Google Ads average reached $5.26 per click. The same piece says paid CTR on queries with AI Overviews dropped 68%, from 19.7% to 6.34%, based on a Seer Interactive analysis of 3,119 search terms across 42 organizations.
For arbitrage, that is not just a search-marketing statistic. It changes the economics of buying broad, lower-intent traffic. If AI Overviews are taking more real estate and fewer paid placements remain above the fold, the click becomes more competitive before the buyer even enters the funnel. That makes weak keyword strategy, soft post-click monetization, and generic intent targeting much harder to defend.
The practical takeaway is that expensive traffic is not automatically bad traffic, but low-precision buying is getting punished faster. Teams that shift closer to transactional intent, stronger funnel matching, and tighter post-click economics are far more likely to survive CPC inflation than teams still trying to brute-force broad search terms into profitability.
