    Quick Answer

    Google Ads will undergo two changes over the next four weeks that directly affect active accounts. Starting August 17, 2026, target CPA and target ROAS will become binding requirements for budget-limited campaigns. Starting September 1, 2026, Google will automatically activate AI Max in Search campaigns with automatically created assets or campaign-level broad match.

    Google Will Automatically Switch Search Campaigns to AI Max Starting September 1, 2026

    PPC Land reported on August 6, 2026, that starting September 1, 2026, Google will automatically migrate Search campaigns with automatically created assets and campaigns with the campaign-level broad match setting to AI Max worldwide. Search Engine Land reported the change the same day, and Search Engine Roundtable on August 7, 2026. According to PPC Land, the announcement was emailed to advertisers on August 5, 2026, without an accompanying blog post.

    AI Max is Google's feature suite for AI-powered Search campaigns. For campaigns with automatically created assets, both expanded search term matching and automatic rewriting of ad copy will be enabled. For campaigns with campaign-level broad match, Google will enable only expanded search term matching. The change applies to the Google Ads interface, Google Ads Editor, and the Google Ads API.

    There is no direct opt-out toggle. According to PPC Land, anyone who wants to avoid the migration must disable the affected legacy features beforehand or activate AI Max themselves and deliberately configure it. The separately announced migration of Dynamic Search Ads remains scheduled for February 2027.

    What Does This Mean for Your Business?

    Small budgets are sensitive to broader ad delivery. If your daily budget is 20 or 30 euros, the question of which search queries your ads serve determines the month's success. Over the next two weeks, review the search terms report for every Search campaign and create a list of negative keywords before the change takes effect. At Stroe Media, we also establish a comparison period in reporting before changes like these so that a cost increase in September is not later dismissed as a coincidence.

    Target CPA and Target ROAS: The August 17, 2026, Change Is Approaching

    Search Engine Land reported on July 28, 2026, that Target CPA and Target ROAS are once again available as standalone bidding strategies during campaign setup, rather than only as suboptions of “Maximize conversions” and “Maximize conversion value,” respectively. The article frames the change as preparation for the August 17, 2026, transition: from that date forward, Google will treat the configured targets for budget-limited campaigns as binding requirements rather than guidelines.

    Budget-limited means Google labels the campaign “Limited by budget” because the daily budget caps ad delivery. That is precisely the normal state for small accounts.

    What Does This Mean for Your Business?

    Campaigns that have previously come in well below their target will move toward that target. Starting August 17, 2026, a configured target CPA of 60 euros that actually delivers 30 euros is an invitation for the algorithm to acquire conversions at a higher cost. Before the deadline, review every campaign with the “Limited by budget” status and set its target to reflect actual performance over the past 30 days rather than an old aspirational figure.

    Limited Ad Serving Will Apply to All Google Ads

    Google's advertising policies help page was updated on August 5, 2026. Google is expanding the Limited Ad Serving policy from specific ad delivery scenarios to all Google Ads. The rollout will be gradual and is expected to be complete by 2028. Search Engine Land reported on it on August 7, 2026.

    Limited Ad Serving caps how often an advertising account can show ads to an individual user until Google considers the advertiser established. Google's qualification criteria include a clear advertiser identity and recognizable branding; misleading or generic Search ads can trigger limits. The help page also gained best-practice sections for each advertising environment, covering Search, YouTube, Gmail, Play Store, and Discover separately.

    What Does This Mean for Your Business?

    This primarily affects new accounts and young brands—exactly the situation when launching a first campaign. Complete advertiser verification, provide a website with a complete legal notice, and display your company name prominently in your ad copy. Advertisers who instead use generic wording with no brand reference risk throttled ad delivery without a visible disapproval in the account.

    Finally, Measure New Customers Without Distorting Your Bidding

    On August 7, 2026, Search Engine Roundtable described the new “Report on new customers acquired” setting. It enables the “New customers” and “New customer value” reporting columns while leaving bidding algorithms unchanged. Search Engine Land reported on it the same day.

    Previously, advertisers had to enable “Bid higher for new customers” with a value of 0.01 to see any new customer data at all without noticeably changing bids. That workaround is no longer necessary. The sources do not provide a complete list of supported campaign types.

    What Does This Mean for Your Business?

    Whether Google Ads brings in new customers or simply reaches existing ones is the decisive question for small budgets. A restaurant or trade business that mainly reaches regular customers through ads is paying for revenue it would have received anyway. Turn on the setting and let it run for four weeks before reallocating your budget.

    Microsoft Advertising Expands Visibility and Testing Features

    Search Engine Journal summarized several Microsoft Advertising updates on August 5, 2026. The analytics tool Clarity is getting new Topic Insights under the AI Visibility name, grouping citations in AI answers by topic, with the metrics “grounding queries,” “citation share,” and “share of authority.”

    Performance Max has two experiment types: uplift experiments measure the incremental impact of Performance Max alongside existing campaigns, while upgrade experiments compare existing Search and Shopping campaigns with the migrated Performance Max version. Microsoft recommends at least 30 conversions in the past 30 days and a duration of four to twelve weeks. Ad Preview Hub now also supports Performance Max and the Bing search results page and generates shareable preview links, as Search Engine Land previously reported on July 27, 2026.

    What Does This Mean for Your Business?

    Many small accounts do not reach the 30-conversion threshold, ruling out these experiments for now. Ad Preview Hub, however, is immediately useful: you can see your ad before launch and send a link for approval instead of emailing screenshots back and forth. That saves one round of coordination per campaign.

    Performance Max: Network Exclusions in Alpha Testing

    PPC Land reported on July 28, 2026, on a tightly restricted alpha test in which Performance Max gains two new selection fields that allow advertisers to deselect the Search Partner Network and the Google Display Network. A campaign-level household income exclusion also appeared on July 27, 2026. So far, only PPC Land has reported this news; there is no official confirmation from Google.

    Access is highly limited. According to PPC Land, requests from agencies were rejected, while other accounts found the fields without any notification. No date for general availability was given.

    What Does This Mean for Your Business?

    This is precisely the control that small Performance Max budgets have been missing most, because wasted reach on the Display Network takes a proportionally large toll on a small budget. Still, do not build this test into your plans: until a release date is confirmed, carefully maintaining audience signals, brand exclusions, and your product feed remains the only effective way to steer performance.

    Specific Actions to Take This Week

    1. 1In Google Ads, filter for all Search campaigns with the "Limited by budget" status and set their target CPA or target ROAS to reflect actual performance over the past 30 days. Deadline: August 17, 2026.
    2. 2Check every Search campaign to see whether automatically created assets or campaign-level broad match is enabled, and decide before September 1, 2026, whether to deliberately activate AI Max or disable the legacy feature.
    3. 3Export the search terms report for the past 60 days and use it to create a list of negative keywords before the AI Max migration takes effect.
    4. 4Enable "Report on new customers acquired" in the customer acquisition settings and collect data for at least four weeks before reallocating budgets.
    5. 5Complete advertiser verification and add your company name to ad headlines so your account does not fall under the Limited Ad Serving rule.
    6. 6Schedule a firm review date in September to compare cost per conversion and search terms with August.

    Frequently Asked Questions

    AI Max is a suite of AI features for Google Ads Search campaigns. These include expanded search term matching and automatic rewriting of ad copy (text customization). According to PPC Land on August 6, 2026, Google will automatically activate these features starting September 1, 2026, in campaigns that currently use automatically created assets or campaign-level broad match.

    According to PPC Land on August 6, 2026, there is no direct opt-out toggle. You have two options: either disable the affected legacy features beforehand—automatically created assets or the campaign-level broad match setting—or activate AI Max yourself and deliberately manage its settings. Either way, you should decide before September 1, 2026, not afterward.

    Google will then treat target CPA and target ROAS as binding requirements rather than guidelines for budget-limited campaigns. On July 28, 2026, Search Engine Land placed the return of Target CPA and Target ROAS as standalone bidding strategies in this context. In practice, this means campaigns that have previously come in well below their target will drift toward that target.

    Limited Ad Serving caps the number of impressions an advertising account can deliver per user until Google considers the advertiser established. According to Google's help page dated August 5, 2026, Google is gradually expanding the rule to all Google Ads, with implementation expected to be complete by 2028. A clear identity and recognizable branding in ads are important.

    Use the new "Report on new customers acquired" setting. Search Engine Roundtable described it on August 7, 2026: it enables the "New customers" and "New customer value" columns while leaving bidding algorithms untouched. This eliminates the previous workaround of setting higher bids for new customers with a value of 0.01 just to get any data at all.

    That depends on the data volume. According to Search Engine Journal on August 5, 2026, Microsoft recommends at least 30 conversions in the past 30 days and a duration of four to twelve weeks for the new Performance Max experiments. Many small accounts do not reach that threshold. The expanded Ad Preview Hub, however, is useful regardless of budget because it simplifies client approvals.

    Conclusion

    Two dates define the rest of the summer: August 17, 2026, for bidding strategies and September 1, 2026, for AI Max. Both changes take effect automatically, and both hit small budgets harder than large ones. The new customer measurement feature is the week's most welcome news because it replaces a common workaround and is ready to use immediately. Limited Ad Serving primarily affects new accounts, and its impact can be mitigated with proper verification.
