Google’s decision to embed ads into its AI-powered search environment is more than a design change. It represents a measurable restructuring of how visibility, engagement, and monetization function within the search ecosystem. For small and medium businesses across North America, the data already shows both risks and opportunities. Understanding these numbers, and what they imply, is critical for adapting strategies in an AI-driven marketplace.
In May 2025, Google expanded Search and Shopping ads into AI Overviews, the AI-generated summaries that appear at the top of results. At the same time, its AI Mode feature, which handles multi-step conversational searches, began displaying ads alongside answers within the dialogue.
This is not traditional keyword-based advertising. Instead, placements are determined by broader contextual signals. Factors such as user intent, search flow, and sentiment are used to decide which ads appear. For marketers, this marks a pivot from transactional targeting toward contextual influence.
The most significant measurable effect so far is the decline in click-through rates. Several independent studies illustrate the magnitude of the shift:
These figures collectively confirm a structural change in how users interact with search results. Engagement is shifting from external websites toward on-page answers, reinforcing the rise of zero click searches.
Zero click behavior is not new, but the introduction of AI summaries accelerates it. Users are increasingly satisfied with AI-generated answers and do not progress to external links. For businesses, this translates into reduced site traffic and fewer opportunities for conversion.
However, impressions and visibility still exist. The metric that loses value is CTR, while brand presence inside AI summaries gains importance. This forces businesses to reconsider ROI models and evaluate advertising performance through metrics beyond clicks.
Despite declining CTRs, the system offers measurable advantages for businesses positioned strategically.
Ads are now appearing at earlier stages in the user journey. A query like “how to build a website for a small business” may produce an AI Overview that includes ads from service providers, creating exposure during the research phase.
AI models prioritize signals of authority. Brands that publish data-rich guides, tutorials, and thought leadership increase their probability of surfacing in both organic and ad-supported placements. This reflects a clear correlation: authoritative content directly influences AI-driven visibility.
Agencies report that impressions in AI environments are comparable to, and in some cases exceed, those of traditional search results. This suggests that while CTR declines, visibility metrics may remain stable or even improve. Businesses can quantify impact by comparing impression-based performance against historic benchmarks.
With ads integrated into AI summaries, placement transparency decreases. Businesses have limited control over context and timing, creating risks of misalignment with brand safety objectives.
Google currently provides minimal reporting for AI-based ad delivery. The absence of granular data complicates ROI assessment. For businesses that rely on precise cost-per-click analysis, this gap represents a significant challenge.
As AI-driven ad placements scale, the competitive environment tightens. Larger advertisers with higher budgets and well-structured feeds are better positioned, potentially marginalizing smaller competitors without equivalent resources.
Only 27 percent of Canadian small and medium businesses report using AI tools as of 2025. With Google’s rollout expanding from the United States to Canada, a gap emerges between businesses prepared with structured data and those without. For Canadian SMBs, adopting practices such as clean product feeds, verified Google Business Profiles, and localized SEO is no longer optional. The data suggests that readiness directly correlates with survival in an AI-shaped marketplace.
AI models rely on feed hygiene. Incomplete or outdated product feeds reduce the probability of inclusion in AI summaries.
Content that demonstrates expertise is weighted heavily by AI. Businesses should analyze their existing resources and identify gaps where tutorials, case studies, or white papers could improve visibility.
Local search queries show less disruption from AI Overviews. Maintaining updated Google Business Profiles and publishing community-relevant content are practices that still deliver measurable value.
CTR and CPC are losing relevance. Impressions, brand mentions within AI results, and long-term engagement measures should be incorporated into performance dashboards. Businesses that adapt analytics frameworks accordingly will maintain clarity in a shifting environment.
Dependence on Google alone increases risk exposure. Data from cross-platform campaigns indicates that combining Google, social platforms, and community-driven marketing balances reach and reduces volatility in ROI.
The integration of ads into AI search results redefines the dynamics of digital visibility. Businesses must treat impressions and presence inside AI answers as performance indicators, not just clicks or conversions. The correlation between authority, structured data, and AI visibility underscores the importance of aligning advertising practices with content credibility.
The broader implication is that digital advertising is transitioning from keyword dependency to context-driven ecosystems. This requires operational agility and a willingness to redefine what constitutes successful performance.
Google’s integration of ads within AI Overviews and AI Mode is not experimental. It is a long-term restructuring of the search economy. The data confirms declining CTRs, rising zero click behaviors, and increased importance of impression-based visibility.
For small and medium businesses, the practical path forward is clear: maintain clean data, invest in authoritative content, leverage local SEO, and diversify digital channels. The businesses that approach this shift analytically, measuring performance through new metrics and adapting strategy based on data, will remain competitive. Those that continue to rely on outdated models will find themselves losing visibility in a marketplace increasingly defined by AI.
