How to Set Up AI Max in Google Ads: Step-by-Step Guide

AI Max in Google Ads is a powerful tool that uses artificial intelligence to optimize search campaigns, helping you achieve better results. Setting it up correctly requires understanding its features and preparing your account and website.

Understanding AI Max: What It Is and How It Works

AI Max in Google Ads is not a separate campaign type, but rather a set of features and settings integrated into your existing search campaigns. Its main goal is to improve performance by automating processes related to reach, ad relevance, and traffic routing. Google states that advertisers who activate AI Max receive, on average, 14% more conversions or conversion value at a similar CPA (cost per acquisition) or ROAS (return on ad spend). For campaigns that previously relied mainly on exact and phrase match keywords, the increase can be significantly higher, reaching up to 27%.

AI Max works thanks to two key components: search term matching and creative optimization.

Search Term Matching

This feature goes beyond traditional keyword match types. AI Max uses broad match technologies as well as asset-based and landing page-based matching to optimize campaign reach. The system analyzes your current keywords, ad copy, and URLs to find new, relevant, and high-performing search terms that you may have missed. This way, you can reach a broader audience searching for your products or services, even if they do not use your exact keywords.

  • How it works: AI Max analyzes user intent, search context, and your existing data (keywords, ads, landing pages) to determine which additional search terms are most relevant for showing your ads. This helps you reach more potential customers.
  • Benefits: Increased reach, discovery of new traffic opportunities, and improved campaign performance.
  • Control: Although AI Max automatically enables search term matching, you can turn this feature off at the individual ad group level if needed to maintain control over specific traffic segments.

Creative Optimization

This part of AI Max focuses on personalizing ads to improve engagement with users. It includes text customization and final URL expansion.

  • Text customization (formerly automatically created ads): This feature uses text from your existing ads, content from your landing page, and generative AI to create personalized ad copy, headlines, and descriptions. The goal is to make ads as relevant as possible to a specific user search query. This means the ad can be adapted in real time to better match exactly what the user is looking for.

  • Final URL expansion: This feature automatically sends traffic to the most relevant pages on your site when that is likely to result in better performance. Final URL expansion will direct traffic only to URLs that are topically related to your ad group and match the user’s query. This is especially useful when you have a large site with many product or service pages.

  • Dependencies: It is important to note that effective use of text customization and final URL expansion often requires conversion-focused Smart Bidding strategies. Also, for final URL expansion to work correctly, text customization must be enabled.

Preparing to Set Up AI Max: The Foundation for Success

AI Max is a powerful tool, but its effectiveness depends greatly on the quality of your preparation and the readiness of your website. Poor preparation can lead to inefficient budget use and disappointment.

Clearly Define Business Goals

Before turning on AI Max, you need to clearly define which results are the priority for your business. The search campaign should be set up around a specific, measurable goal. This could be increasing the number of conversions, increasing conversion value, lowering CPA, or reaching a certain ROAS level. Without a clear understanding of your goals, you won’t be able to properly evaluate AI Max’s performance.

A Well-Prepared Website

Your website is a key element for AI Max to work successfully. Google’s algorithms will select elements from your site to optimize ads, so it must meet the highest standards.

  • Compliance with Google policies: The site must follow all Google policies regarding content, technical implementation, and user experience. This includes page speed, mobile responsiveness, and the absence of hidden text or spam.
  • Clear calls to action (CTA): Every page should have a clear and prominent call to action that encourages the user to take the desired action (for example, “Buy now”, “Request a call”, “Download the price list”).
  • Clearly communicated benefits: It is important to clearly communicate the benefits of your products or services. Why should a customer choose you? The benefits should be obvious and compelling.
  • Structure and content: The site should have a logical structure, clear navigation, and high-quality, relevant content. The algorithm will analyze page content to create personalized ads and select relevant URLs.

Technical Readiness and Conversion Tracking

  • Conversion tracking: Make sure your conversion tracking is set up correctly and reliably. This is the foundation for any campaign optimized using Google Ads automated strategies, including AI Max. Conversion data is the “fuel” for the algorithms.
  • UTM tags and tracking parameters: Although AI Max can automatically optimize URLs, it is important to configure tracking parameters correctly, especially if you use complex tracking templates. When using final URL expansion, dynamic URLs can sometimes lead to 404 errors if tracking templates are not compatible.

    • Recommendation: If your campaign uses a tracking template, check before enabling AI Max whether the dynamic URLs generated by AI Max work correctly on your site. Make sure tracking parameters are set up properly from the dynamic landing page. This is especially important if the lpurl tags follow specific patterns and tracking parameters come after the page address.

Practical Steps for Setting Up AI Max

Setting up AI Max involves activating certain settings at the campaign level and, if needed, making more detailed adjustments at the ad group level.

Activating AI Max at the Campaign Level

  1. Select the search campaign: Go to the “Campaigns” menu in Google Ads and choose the search campaign you want to optimize.
  2. Campaign settings: In the campaign section menu, find and select “AI Max”.
  3. Enable AI Max: Turn on the main “AI Max” option. This is usually a toggle or checkbox.
  4. Choose AI Max features: After activating AI Max, you can choose the specific features you want to use:

    • Search term matching: This feature is usually enabled automatically along with AI Max.
    • Text customization: This feature can be turned on or off.
    • Final URL expansion: This feature can also be turned on or off. Remember that it requires text customization to be enabled.

Advanced Settings and Management

  • Turning off search term matching at the ad group level: If you need tighter control over which search terms trigger ads for a specific ad group, you can disable search term matching at that ad group level even if AI Max is enabled at the campaign level. This is done through the ad group settings.
  • Turning off AI Max: To fully disable AI Max for a campaign, you can switch the relevant setting to “off”. However, if you previously enabled text customization or final URL expansion (status “OPTED_IN”), you will also need to turn off these features (“OPTED_OUT”) in the campaign settings, otherwise disabling AI Max will cause an error. When AI Max is turned off, all text ads it created will stop serving, but they will remain available for analysis.
  • Using the features together: It is important to understand that AI Max for search campaigns is an optimization layer that allows you to keep the familiar search campaign structure while improving certain settings, such as brand control elements and broad match, into a single AI-based system.

Optimizing and Monitoring AI Max Campaigns

After setting up AI Max, the process does not end. Regular monitoring and optimization are key to achieving the best results.

Reporting and Data Analysis

Google Ads provides improved reporting for AI Max campaigns, giving greater transparency into how the AI is working.

  • Search terms, ads and URLs combinations report: This report provides data on the performance of combinations of search terms, headlines, and landing pages. It shows which search queries triggered your ads and how those specific combinations performed.
  • Match types: Reports can show a new “AI Max” match type for additional search terms, as well as a source column indicating whether the result came from broad match expansion or keywordless matching.
  • Keyword report: New summary rows show “AI Max” to help you understand the overall contribution from AI Max.
  • Landing page report: A new “Selected by system” column shows the performance of landing pages chosen by AI Max.
  • Assets report: Shows the performance metrics of AI Max-optimized assets.

When Is AI Max Appropriate, and When Is It Not?

  • Best used for:

    • Expanding reach: When you want to find new audience segments and increase traffic volume.
    • Automation: If you want to reduce the time spent on manual keyword management and ad optimization.
    • Large product catalogs: If you have many products or services, AI Max can help direct users to the most relevant pages more efficiently.
    • Campaigns that have already reached their limit: When traditional optimization methods no longer deliver significant growth.

  • Not ideal for (or use with caution):

    • A very narrow niche with specific terminology: Where too much automation may lead to irrelevant traffic.
    • No clear goals and no quality website: AI Max requires a strong foundation.
    • Need for full control over every search query: AI Max aims to scale demand, which can make it harder to control query categories.
    • Heavy use of keyword exclusions: While AI Max provides management options, too many exclusions can limit its potential.
    • For a campaign’s first launch: It is recommended to first establish the basic campaign structure, collect data for several weeks, and then turn on AI Max. Some sources recommend waiting at least 6 weeks before activation.

Common Mistakes and How to Fix Them

  • Mistake: Incorrect conversion tracking.

    • Fix: Check your Google Tag Manager, Google Analytics, or Google Ads pixel settings. Make sure conversions are recorded correctly across all device types and browsers.

  • Mistake: Poor user experience on the website.

    • Fix: Optimize page load speed, make the site mobile-friendly, improve navigation, and make CTAs clearer.

  • Mistake: Insufficient testing before launch.

    • Fix: Use A/B testing for your landing page and test different ad variations. Roll out AI Max gradually while monitoring results.

  • Mistake: Tracking templates incompatible with final URL expansion.

    • Fix: Carefully review your tracking template. If you use dynamic parameters, make sure they are passed correctly and that the landing pages AI Max sends traffic to can handle them.

AI Max is a significant step forward in using artificial intelligence to optimize Google Ads. Proper setup, understanding how it works, and ongoing monitoring will allow you to make the most of its potential to achieve your business goals.
