Are you wondering how AI Max ads refine search intent?
With AI Max, Google no longer stops at keywords: it analyzes context, search signals, and content to deliver ultra-relevant ads. For an e-commerce merchant, this means more effective campaigns, a better return on investment, and less budget waste.
But beware, this advanced automation requires a fine understanding of the mechanisms to avoid pitfalls. You need to know how to set up your campaigns, control URLs, and interpret transparency reports.
So, how do AI Max ads refine search intent? In this article:
What is AI Max for Search and why does it matter?
How does search term matching work?

What is the impact of final URL expansion?
How can Qstomy complement your AI Max campaigns?
Let's get started.
Summary
What is AI Max for Search and why is it important?
AI Max for Search is a new advertising campaign from Google that leverages artificial intelligence to display ads based on search intent, rather than keywords alone. Launched in 2025, it marks a turning point: keywords become themes, and AI decides which ads to show, to whom, and when.
For an e-commerce retailer, this is an opportunity to reach potential customers with increased precision. AI analyzes billions of signals: browsing history, purchasing behavior, query context, etc. As a result, your ads appear in front of people who are genuinely interested, which increases click-through rates and conversions.
However, this automation requires letting go of some control. You must trust the AI while keeping an eye on performance. It is a balance between delegation and supervision.
Furthermore, AI Max integrates naturally into the Google Ads ecosystem, facilitating the centralized management of your campaigns. This allows you to compare performance with your classic Search campaigns and quickly identify the most profitable drivers. This overall view is valuable for adjusting your advertising strategy in real time.

How does search term matching work?
Search term matching is the heart of AI Max. Instead of being limited to exact keywords, Google uses AI to understand what the user is really looking for. For example, if you sell photo frames, a query for "4x6 frame" will trigger your ad even if your keyword is "photo frame".
Google analyzes your keywords, content, and landing pages to determine relevance. It's a bit like Netflix recommendations: the AI suggests what best matches the user's tastes, even if it goes beyond simple word matching.
To optimize, make sure your keyword lists are well-structured and your product pages are rich in information. The AI relies on this data to refine its choices.
Additionally, it is essential to regularly monitor the search terms report to identify unexpected queries. This allows you to adjust your exclusions and refine your themes, thereby ensuring that your budget is spent on intent that is genuinely relevant to your offer.
How does text customization improve ads?
Text customization, formerly known as "automatically created assets," allows AI to generate headlines and descriptions tailored to each search. For example, if a user searches for "4×6 frame," Google can display "4×6 Frames in Stock" instead of your generic headline "All Frame Sizes."
This feature relies on your existing ads, landing pages, and assets. The AI combines these elements to create ultra-relevant messages, which improves click-through rate and the quality of the user experience.
You can view the automatically generated headlines and descriptions in the "asset performance" report and delete them if necessary. This gives you valuable control over your brand image.
To get the most out of this feature, make sure to provide varied and high-quality assets. The more material the AI has, the more impactful messages it can create. Regularly test different combinations to discover what resonates best with your audience.
What is the impact of final URL expansion?
Final URL expansion allows Google to choose the most relevant landing page for each query, instead of always using the URL you defined. Combined with text customization, it creates an ad that is fully tailored to search intent.
For example, if you sell shoes, Google can direct a user to a specific category page rather than your homepage. This improves user experience and conversion chances.
You can control this expansion by defining URL inclusions and exclusions. For example, exclude your blog pages if you do not want to pay for that traffic. This is a powerful lever for optimizing your budget.
It is also recommended to check that your landing pages are consistent with your ads and fast to load. A well-designed page reinforces the relevance perceived by the user and improves your quality scores, which can reduce your advertising costs.
What are the other key features of AI Max?
AI Max includes brand settings that allow you to include or exclude brand names in your ads. For example, if you only sell Nike and Adidas brands, you can exclude queries containing "Reebok" to avoid paying for irrelevant clicks.
Google is also improving reporting transparency. Unlike Performance Max, AI Max provides a search terms report with an "AI Max" column that shows the exact query and the combination of query, assets, and final URL. This allows you to understand precisely why an ad was shown.
These features strengthen your control while taking advantage of the power of AI. You can adjust your campaigns based on actual data, rather than being subjected to the decisions of the algorithm.
Finally, do not hesitate to use reports to identify emerging trends. For example, if certain queries generate a lot of conversions, you can add them as positive keywords to boost their visibility. This proactive approach maximizes the effectiveness of your campaigns.
How does AI Max compare to classic Search campaigns?
Classic Search campaigns rely on keywords and manual bidding. AI Max goes further by using AI to analyze search intent and automate decisions. Keywords become themes, and AI manages delivery, text, and URL.
This means you delegate some control to Google, but in exchange, you benefit from better relevance and potentially higher performance. Testing shows that AI Max campaigns can generate more conversions at the same cost, thanks to more precise targeting.
However, it is essential to monitor performance closely and adjust your strategies. AI is not infallible, and human supervision remains necessary to avoid costly mistakes.
For a smooth transition, start by launching an AI Max campaign in parallel with your existing campaigns. Compare results over a few weeks, then adjust your budgets accordingly. This progressive approach allows you to measure the real impact without risking a loss in performance.
What are the benefits for an e-retailer?
For an e-merchant, AI Max offers several concrete advantages. First, a better match between ads and search intent, which increases the click-through rate and reduces the cost per click. Second, automation that saves time: you no longer have to create hundreds of ad variations.
In addition, final URL expansion improves the user experience by sending visitors to the most relevant page. This can increase the conversion rate and average basket value.
Finally, reporting transparency allows you to understand what is working and continuously optimize your campaigns. This enables you to allocate your budget to the most profitable queries.
Furthermore, AI Max makes experimentation easy. You can test different messages and landing pages without manual effort, which speeds up learning and optimization. This agility is a major asset in a competitive environment where every click counts.
What are the risks and how to avoid them?
The main risk of Performance Max is the loss of control. The AI can serve ads on unexpected queries or generate copy that does not match your brand image. To prevent this, use brand and URL exclusions, and regularly monitor performance reports.
Another risk is budget waste if the AI targets excessively broad queries. To limit this, define precise URL inclusions and use negative keyword lists.
Finally, test progressively. Start with a small Performance Max campaign, analyze the results, then adjust before launching on a large scale. Caution is key.
It is also wise to set up performance alerts to be notified in case of a sudden drop in ROAS. A quick reaction can prevent significant losses and allow you to course-correct before the problem escalates.
How to set up an effective AI Max campaign?
To set up an effective AI Max campaign, start by defining your goals: sales, leads, traffic. Then, provide quality data: keywords, assets, landing pages. The AI needs this information to learn and optimize.
Use URL inclusions and exclusions to guide the AI to the most relevant pages. For example, include your product pages and exclude your blog pages if they do not generate sales.
Finally, monitor performance regularly and adjust your bids and budgets. The AI learns continuously, but your supervision is essential to maximize results.
Also, remember to structure your campaigns by theme or product type. This helps the AI better understand your catalog and optimize delivery. A clear structure also makes it easier to analyze performance and make decisions.
How to measure the performance of AI Max campaigns?
Performance measurement is crucial. Use the search terms report to see which queries trigger your ads. The "AI Max" column shows you the exact combination of query, assets, and final URL, allowing you to understand the AI's decisions.
Also track classic metrics: click-through rate, cost per click, conversion rate, return on ad spend (ROAS). Compare these indicators with your previous campaigns to assess the impact of AI Max.
Don't hesitate to test different configurations and analyze the data to refine your strategy. Performance improves over time and with AI learning.
For a deeper analysis, segment your data by device, time of day, or query type. These insights help you identify optimization opportunities, such as adjusting bids for mobile or increasing budgets on the most profitable slots.
