What AI Is Doing to Your Google Ad Spend (And What to Do About It)
Google Ads has been the default paid channel for small businesses wanting search visibility for the better part of two decades. That default is under pressure. AI search is changing how customers move through the buying journey - and it's quietly reducing the return on paid search for many business types.
The AI Overviews effect on paid search
When Google serves an AI Overview at the top of a search results page, it pushes everything else down. Organic results move lower. Paid ads move lower. In many cases, the customer reads the AI summary, gets their answer, and never clicks through to the results below. For businesses paying for paid search clicks, this means paying more for less. Cost per click has been rising across most Australian industries over the past 18 months. Click-through rates on many commercial queries are down. The traffic that does come through is more expensive than it used to be.
It's not the same for every business
To be fair: paid search still works. For high-intent transactional queries - 'emergency plumber Sydney', 'book a physio appointment Manly' - paid ads remain effective because the user wants to act immediately and will click. Where paid search is losing ground is in the research and consideration phase. Queries like 'best accountant for small business', 'how to choose a web designer', 'digital marketing agency reviews' - these are being answered by AI before the user gets to the paid results. The user forms opinions before they click anything.
What this means for your marketing budget
A few practical implications for Australian small business owners: Don't abandon paid search if it's working. But don't assume it will keep working at the same cost and effectiveness. Monitor your cost per acquisition carefully over the next 12 months. Invest in organic AI visibility before you increase paid budgets. A business that appears organically in AI recommendations is capturing customers at a lower long-term cost than one that relies purely on paid clicks. Brand awareness matters more than it used to. If customers encounter your business name across AI recommendations, directories, and reviews before they click an ad, your paid conversion rates improve significantly.
Where to put your attention instead
The highest-leverage shift for most Australian small businesses is moving budget and attention from paid clicks toward organic AI visibility. AEO and GEO work doesn't have a per-click cost. Once you're appearing in AI recommendations, you appear consistently - for every relevant query, not just the ones you're paying to show up for. Meta advertising, done properly, also continues to deliver strong returns for local businesses. The key distinction: Meta interrupts customers with relevant messaging. AI search captures customers who are already looking. Both have a role. Neither replaces the other.
Paid search isn't going away, but treating it as the primary lever for online growth is increasingly risky as AI changes how customers search. The businesses building organic AI visibility now are insulating themselves against rising paid costs while capturing a growing share of AI-referred traffic.
