Google Ads AI Max is one of the most significant updates to Search campaigns since responsive search ads replaced expanded text ads. For small business owners and managers in Indonesia, understanding how this feature works has become a necessity, because it directly affects how efficiently your ad budget is spent. The good news is that you do not need a bigger budget to benefit from it. Rethinking your campaign settings is enough.
This article explains what Google Ads AI Max is, how it differs from Performance Max, and seven practical steps you can put into practice this week. It also includes the latest data on the feature's performance and on the Indonesian digital advertising market, so your decisions rest on data rather than guesswork.
What is Google Ads AI Max and why does it matter now?
Put simply, Google Ads AI Max is a set of AI-powered features that Google ‘layers’ on top of your existing Search campaigns, including Search Themes, URL Expansion and automatic ad copy generation. Google introduced the feature in 2025 and has kept expanding it, on both targeting and ad creative.
What makes it worth your attention now is the data: campaigns that switch on the full set of AI Max features record, on average, around 7% more conversions or conversion value at a broadly similar CPA or ROAS (Google Ads Blog, 2026). In other words, without adding a single rupiah to your budget, your ads could deliver more simply by switching on the right features.
How AI Max differs from Performance Max
Many advertisers struggle to tell Google Ads AI Max and Performance Max (PMax) apart. Performance Max runs a single campaign across the whole Google network, from Search, Display, YouTube and Gmail to Maps and Discover, and it works best when the account already has a solid base of conversion data. AI Max, on the other hand, works specifically inside a Search campaign that is already running: it widens your keyword reach and adapts your ads automatically without changing the overall campaign structure. So the two work alongside each other.
7 ways to use Google Ads AI Max for your business
Here are seven steps you can take so the feature genuinely serves your business goals, instead of simply sitting switched on in the dashboard.
1. Audit the Search campaigns you already run
Before you switch on Google Ads AI Max, check how your existing Search campaigns are performing. Look at which keywords already produce steady conversions, because AI Max expands your reach from a foundation that is proven to work. It does not create results from scratch.
2. Turn on Search Themes gradually
Search Themes let AI Max understand the broad themes of your business, beyond a rigid list of keywords. Start with one or two of the most relevant themes, monitor the results for two weeks, and only then add more.
3. Use URL Expansion with clear limits
AI Max's URL Expansion feature can send traffic to other pages on your site if it judges them more relevant. To stop it drifting away from your main product or service pages, use exclusion settings to define which pages may and may not be used as destinations.
4. Strengthen your landing page before switching on AI Max
However good AI Max's targeting is, the end result still depends on your landing page. Make sure the destination page has a clear CTA, loads quickly and gives information that answers the user's search intent directly. Webzoo covers this practice in more depth in our complete guide to Google Ads for Indonesian businesses.
5. Track Quality Score before and after
Because AI Max adapts your ad copy automatically, it is important to compare your Quality Score before and after the feature is switched on. If you are not familiar with this metric yet, you will find a full explanation in our article on strategies to improve your Google Ads Quality Score.
6. Combine it with remarketing for visitors who have not converted
AI Max does widen your reach to new users, but do not forget the visitors who have already been to your site without buying. Combining it with a remarketing strategy helps close this conversion gap; learn how it works in our Google Ads remarketing guide.
7. Set a realistic daily budget and raise it with care
Because the feature works automatically, it is tempting to raise the budget sharply in the hope of bigger results. The safest approach is to raise the budget gradually while monitoring your daily CPA. You can read more tips on this in our guide to running Google Ads without wasting budget.
Indonesian digital ad market data and what it means for Google Ads AI Max
Market data supports learning this feature now. The Indonesian digital advertising market is estimated to be worth USD 3.41 billion in 2026 and is projected to grow at a CAGR of 5.7% to reach USD 4.51 billion by 2031 (Mordor Intelligence, 2026). This growth reflects ad budgets shifting from traditional media to digital: digital accounted for 75% of total Indonesian ad spend in 2025, up 13.8% on the previous year (GroupM via Campaign Indonesia, 2025).
Meanwhile, millions of Indonesian small businesses (UMKM) have already gone digital through marketplaces, websites or social media. Many of them still do not use digital advertising strategically, so automation features like this can be a shortcut to catching up without having to learn complicated manual settings.
One thing to watch out for: several industry studies report a fall in both organic and paid click-through rates since AI Overviews appeared in search results. This makes the efficiency of paid campaigns such as Google Ads AI Max even more important, because the space for organic clicks keeps shrinking.
When should small businesses switch on Google Ads AI Max?
The best time to switch on Google Ads AI Max is after a basic Search campaign has been running for at least 30 days with clear conversion data. If your account is still new or your conversion volume is very small, tidy up the campaign foundations first, then switch on the AI Max features gradually. For businesses with a limited budget, we suggest starting with a simple Search campaign on a monthly budget of around Rp 3-5 million, then adding AI Max features once the conversion pattern looks stable.
Common mistakes when setting up Google Ads AI Max
The most frequent mistake is switching on every Google Ads AI Max feature at once with no exclusions, which makes it hard to know which element is actually driving results. Another is ignoring the weekly performance report: the feature needs regular monitoring to keep its optimisation pointed at your business goals, rather than at click volume alone.
Conclusion: make Google Ads AI Max part of your ad strategy
In the end, Google Ads AI Max is a real opportunity to get better results from the same budget. With a well-organised campaign audit, a strong landing page and regular monitoring, the seven steps above can help your business make the most of the feature without increasing your ad spend. If you would like hands-on help setting up and managing your campaigns, Webzoo's Google Ads team can support you from the initial audit through to ongoing optimisation.
