Google’s 2025 release of AI Max was introduced as the future of search campaigns at our doorstep.
The promise? Intelligent automation that expands reach, optimises ad assets, and prioritises relevance. Many see AI Max as just the next step in keyword-less advertising. So should businesses adopt it early to gain an edge, or will it become an expensive experiment?
Key Takeaways:
- AI may be worth it for your mature, maxed out search campaigns
- Be thoughtful when deciding how to incorporate AI Max into an existing campaign with pre-established keywords – consider our strategy
- Your budget should be large enough to absorb Google’s initial experimental phase
- Make sure your site is well structured and filled with comprehensive content for AI Max to use in ad content
- AI Max can be highly successful in increasing conversions, but only when incorporated in the right way and at the correct time.
What is AI Max?
AI Max is a Google Ads feature that uses artificial intelligence to optimize Search campaigns.
By leveraging real-time data and user signals, AI Max creates tailored ads and delivers a dynamic, customized approach to campaign delivery.
What does AI Max Promise to Bring to Your Campaign?
AI Max promises to bring relevance, personalisation, transparency and control to your search campaign.
- Relevance First: Prioritises matching ads to user intent for more engagement.
Insight: Alternative current dynamic google ad campaigns already use syntax to gain insight into user search intent. However, the intelligent algorithmic approach of an AI tool elevates this predictive benefit to new heights.
This personalised approach can definitively increase engagement, but should we be worried about all advertising becoming too similar? If everyone utilises AI to custom design ads, will it result in the loss of easy brand differentiation?
Although important to consider, this seems unlikely upon efficient utilisation of the controls that AI Max offers customers over brand affiliation, keywords used and performance reporting access.
Personalisation at Scale: Delivers AI-powered custom-design google ad experiences using audience user data and generative AI.
Transparency: Offers high level reporting tools to maintain advertiser understanding of their campaign’s performance.
Alternative type of Control: Offers a balance of allowing general advertiser direction (key word selection, chosen demographic and budget) with adaptable algorithms that change strategies as needed.
How Does AI Max Help Your Ad Campaign?
AI Max aims to simplify campaign management while improving conversion potential. Specifically:
Overall increases in conversions: AI customisation may draw in 14% more conversions. In campaigns that keep their keyword consistent after the addition of Ai Max the uplift is predicted to be higher, at around 27%.
Our Insight: We’re currently testing AI Max across different industries to understand where it truly adds value. Early results suggest it can be a smart move, similar to Performance Max, for businesses comfortable with branding risk.
Why? Because AI may not reliably represent your brand at first. While customizing ads for users, it could misinterpret your tone or mission. That’s why we see AI Max as powerful when paired with human oversight, not as a standalone solution.
Expanding reach: Showing your ads to users searching for broadly relevant terms.
Improved Audience targeting: Using user data to identify people likely to engage with your content.
Automated Asset optimisation: Automatically refining ad copy for better visibility and performance.
Incorporation of Generative AI: Creating tailored ads based on real-time data and user signals.
What’s the Difference Between AI Max and Performance Max?
AI Max is like Performance Max; a dynamic tool designed for keyword-less search campaigns. The key difference is control. AI Max provides more transparency and reporting for search campaigns, while Performance Max sacrifices granular control for full automation across all Google channels. This broader focus makes Performance Max less effective for search-specific goals, whereas AI Max is purpose-built to optimise every facet of a search campaign.
What are the Key Features of AI Max?
The key features included in Google’s AI Max are search expansion, text customisation and final URL expansion.
Search Term Expansion
61% of users want brands to demonstrate understanding of the exact intent behind their query. Search Term expansion allows your ad to be shown in response to signaled intent (based on user data) instead of only specific keywords which would limit your reach. This even includes geographical intent: no need to say where you are, AI Max has it covered.
Even if someone didn’t hit on the exact right words to hit their saving grace – your business – the AI understands what they’re really looking for.
Text Customisation
The generative component of AI Max works to create a further customised ad campaign for potential customers by generating the ad headlines and descriptions that will result in better engagement. It can compose this from scratch or include wording from an existing ad. The most interesting facet of this feature is its total personalisation. The AI will generate several variations of relevant ads tailored to user data.
For example: User A may search for ‘dog joint pain supplements’. The AI identifies high buyer intent and produces an ad headline that provides direct access to a product. It has identified past price sensitive searching, and incorporates this:
‘Support joint pain relief for your dog. Clinically tested supplements. 30 day money back guarantee.’
For User B who searched for ‘Natural supplements for senior dogs’. The AI is able to identify specific concerns for older dogs and incorporates this into an ad headline:
‘Natural Supplements for senior dogs’ and ad content: ‘gentle, vet approved ingredients to support mobility and longevity.’
AI Max may produce hundreds of tailored ad micro variants, each optimised for different concerns within a single domain.
Opportunity: This could result in better engagement as more issues are catered to with your brand as the solution.
Risk: AI Max may generate ads that make unapproved promises, whose messaging drifts off course, or which have poor language choices for your intended tone.
Final URL Expansion
AI Max offers analysis of user data to evaluate which landing page on your site is most likely to result in a conversion. Where standard search campaign tools blindly follow the link you set to a landing page, the dynamic approach assumes control of the decision. For this feature to actually be useful, it’s important to have a solidly setup site; all your pages should be ‘the golden child’.
Premium asset optimisation?
Text customisation and Final URL expansion are the key features involved in enabling promised premium asset optimisation; the idea that the AI adapts your advertising to be optimal over changing user data and trends.
But is an AI Max campaign for you?
When Should You Avoid AI Max?
AI Max includes powerful automation, but it’s not right for every business. Before enabling it, consider these scenarios where the risks may outweigh the reward:
1. Your Website Is Unstable or Lacks Content
AI Max relies on your site’s content to determine relevance and optimal landing pages. If your website has broken links, slow load times, or thin content, the algorithm will struggle to deliver accurate results.
This may result in users being delivered to irrelevant loading pages, an error, or to content that may have been relevant but is currently too ill prepared to inform them appropriately.
For example: A local plumbing business that has just launched a new drain clearing service but hasn’t updated a relevant service landing page may experience their ads directing users to irrelevant pages, hurting conversions and wasting money.
AI Max gathers its source material to generate ad content from your website. If your content is not completely up to date (or not rich enough), your ad is going to be lacking. The result: More back clicking and financial (and emotional) damages.
2. Your Budget Isn’t capable of absorbing Google’s initial mistakes
AI Max uses machine learning, which means it needs time (and budget) to gather data and optimize performance. The first 2 weeks are purely experimental. You shouldn’t include this time period in your early analysis of productivity.
You need enough of a budget to be able to afford to conduct a 4 week minimum experiment ( 2 weeks out of the learning phase) as to the efficiency of AI Max for your search campaign. Our recommendation is to allow $150 per day.
3. You Operate in a Compliance-Heavy Industry
Industries like finance, healthcare, or law have strict advertising regulations for the wellbeing of their clients. AI-driven automation may generate ad copy or target audiences in ways that unintentionally violate compliance rules.
This is part of the problem surrounding control: You’ve got way less of it. Perhaps you’d rather not sacrifice the initial campaign period to the training wheel phase.
When Should You Enable AI Max?
1. Your Campaign’s Search Volume is Maxed Out
If you’ve maxed out search volume, AI Max can help break through that ceiling. By going beyond exact matches to interpret broader user intent, it expands your reach to new audiences. This means more impressions, more clicks, and ultimately more conversions.
Example: An e-commerce brand selling gaming set ups that consistently ranks for its core keywords but wants to capture adjacent searches like “best gifts for tech lovers” can utilise AI Max to cater to those untapped queries.
2. You Have High-Quality Landing Pages
AI Max takes a lot of control with Final URL Expansion by redirecting search engine users to what it sees as appropriate landing pages. If those pages are indeed structurally clear and optimised for conversion, the algorithm can confidently direct traffic to the most relevant page.
For Example: A plumbing company with pages like “Emergency Repairs” and clear CTAs such as “Book Now” will perform better. AI Max can direct users searching for “fix leaking pipe tonight” straight to the emergency repair page, matching their intent.
3. Your Content Is Updated and Relevant
As AI Max uses generative AI to create customised ads with content pulled directly from your website, it will be most effective if the content on your site is relevant to its title page, clear and comprehensive. The assets it generates will be an accurate representation of your service, product and people.
Example: A travel agency that regularly updates destination guides and current deals via blog posts will benefit from AI Max’s ability to generate relevant headlines and descriptions from concrete source material.
A Last Recommendation:
Consider if using AI Max in an existing search campaign for which you have already won key words would work for you – there is a risk that it may reset the marketing strategy already employed to secure those key words.
How to Tell if AI Max is the Right Choice For You
By our recommendation, safe industries to start applying AI Max within are eCommerce or service booking sites. It is probable that those sites both generate enough revenue and result in enough conversions to lessen the risk of AI unreliability.
*This minimum budget and conversion number are vital so as not to dilute your existing ad performance, and to ensure that google has enough learning points, respectively.
How to set up AI Max
If you’ve weighed up the pros and cons of Google Ads AI Max against your business specific expertise and decided it’s a gamechanger, there’s good news: It’s a one click application!

Pro Tips
- Use brand exclusions and URL controls to maintain brand safety and regulation.
- Monitor ad spend versus ad performance closely during the learning phase.
- Combine AI Max with strong conversion tracking for best results.
How Should You Incorporate AI Max into an Existing Campaign?
It could be a brilliant strategic move to incorporate AI Max alongside a successful, but maxed out search campaign, but it’s crucial to test its effectiveness first. If AI Max is allowed to immediately gain control of a successful campaign, its algorithmic learning phase may reverse carefully curated progress.
Instead, you should consider excluding your successful primary key words from the AI, switching it on within your campaign to win secondary keywords that may boost your ranking.
This way (after the post experimental period performance evaluation) your pre-existing google ad targeting is preserved while allowing room for AI Max to optimise ads for secondary and contextual keywords.
Main Takeaway’s on Google’s AI Max
Overall, AI Max is a strong advancement in keyword-less search campaigns. It’s important to consider both the benefits and risks that AI Max introduces to your campaign.
On one hand, it steps away from manual control, opening up opportunities for the AI to misrepresent your brand.
On the other hand, upon effective use of the controls offered within it, AI Max could be a revolutionary opportunity to boost conversions.
