Dynamic search ads left a receipt. The AI Max journey view is still a promise.

What Google promised on 23 September#

The fox reads the small print before the headline. On 23 September 2026, Google announced two AI Max updates: the closed beta of AI Brief reaches Dutch, French, German, Italian, Japanese, Portuguese and Spanish, and Google Ads will gain a reporting feature that gives "a single, unified view of the Search ads journey". The post says it will show what search terms triggered your ads, which creative assets the user saw, and where they landed. Then comes the sentence that matters most: "We'll share additional details and availability later this year."

Barry Schwartz of Search Engine Roundtable covered the same announcement as a report advertisers using AI Max "will soon have access to". Soon is not a date. A promise with no date is a scent, not a trail, and a careful account manager should treat it that way.

That matters because dynamic search ads are on a clock. Google extended the timeline and says the sunset and auto-upgrade of dynamic search ads "will begin in February 2027". Google's own help page on dynamic search ads repeats it: from February 2027, campaigns using dynamic search ads "will automatically be upgraded to AI Max". If you run them, your reporting is about to change shape whether or not the new view has shipped.

Only one slice of accounts has already moved. The same Google post says campaigns using automatically created assets and the campaign-level broad match setting "will continue to be auto-upgraded starting in September 2026". Our earlier notes on the AI Max migration audit and the invalid traffic cost of the upgrade cover that first wave. This piece is about the second one, and about the receipt you will want when it arrives.

The plan for the rest of this article is simple. First, what dynamic search ads reporting actually gave you. Second, what AI Max reporting already shows today, versus what is only promised. Third, what the evidence says AI Max delivers. Fourth, five real checks to run before your account is upgraded for you.

What dynamic search ads reporting gave you#

Dynamic search ads work by reading your site. Google's help page says they "use content from the landing pages on your website to target your ads to searches", and that Google "will dynamically generate an ad with a clear headline for the most relevant page on your site" (Google Ads Help). You supply the description and the page feed or domain; the machine supplies the query match and the headline.

In exchange you got a report that still reads like a receipt. The dynamic search ads search terms report lists the headlines generated for your ads while users viewed them, and the performance of the landing pages where your ads showed. The landing page shown is "the final URL after redirects", so a chain of redirects does not hide where the click ended.

This is the trail a fox can follow. Every row in the Google Ads search terms report answers three questions at once: what did the person type, what did we say back, and where did we send them. Strip out the DSA-specific columns and the general search terms report is still a list of terms "that a significant number of people have used, and that resulted in your ad being shown".

The catch inside the Google Ads search terms report#

The google ads search terms report has never been complete. Google says some terms "don't have enough query activity" and are omitted "in order to keep with our standards on data privacy". So even the receipt you hold today has a torn corner, and the search terms report Google Ads shows for an AI Max campaign inherits the same privacy floor. If you have never priced that gap for your own account, the upgrade is a good moment to do it: export the terms, total the cost against the account, and note the share sitting under "other" or missing.

The reason it matters is that your google ads search terms are the only place a dynamic ad's targeting decisions become visible. When Google reads your page and picks a query, the search terms row is the proof. Lose it, or blur it, and the machine marks its own homework.

Read that table left to right and you can see the design of the promise. Google is not inventing new fields. It is joining fields that already exist into one screen, which is useful to a human and, more usefully, a hard thing to leave out once it exists.

What AI Max reporting already shows, and what is only a promise#

Here is a detail worth knowing. Google's help page for reporting in AI Max campaigns already describes a combined view that "lists the search terms that triggered your ads and shows the headlines, landing pages, campaigns, and ad groups that made up the full customer ad journey" (About reporting in AI Max campaigns). The keyword report carries rows labelled "Total: AI Max expanded matches" and "Total: AI Max landing page matches". The landing page report includes "advertiser-provided URLs and Final URL Expansion URLs".

So AI Max reporting is not a blank. What the 23 September post adds is a promise of a cleaner, single interface, plus the wording that it will let advertisers "validate the strategic value AI Max brings". That reads as a sales tool as much as an audit tool, which is fair: the platform wants you to keep the feature on. Your job is to keep your own copy of the evidence.

That joke lands because it is the brief. Finance does not ask whether a match type was broad. Finance asks why one campaign spent so much, and whether it would have spent anything at all without the machine.

Why final URL expansion is the field to watch#

Of the three AI Max features, final URL expansion changes your risk most. Google's page on how AI Max works describes it as sending "traffic to the most relevant URLs on your website when it's likely to result in better performance". For dynamic search ads that already pick landing pages, the difference is smaller. For a standard keyword campaign it is a large change: the ad no longer lands where you decided.

Google says upgraded dynamic search ads campaigns keep their legacy URL controls, and it describes the three features, search term matching, text changes and final URL expansion, as switched on together (Google Ads and Commerce blog). Whatever the toggle says, verify it in the landing page report. Final URL expansion is only a benefit if you can see the pages it used, and only a risk if you cannot.

The ALM Corp guide to upgrading dynamic search ads to AI Max suggests pulling recent conversions, conversion value, cost per acquisition, return on ad spend, assisted conversions, search terms and landing pages before you move. It was written before Google extended the timeline, so its dates are stale, but the checklist is sound. We turn it into five steps below.

What the evidence says AI Max delivers#

Google's own numbers have moved. At launch in May 2025, the AI Max announcement said advertisers "will typically see 14% more conversions or conversion value at a similar CPA/ROAS", and that the uplift was "even higher at 27%" for advertisers on exact and phrase match. By April 2026, Google's upgrade post put the average at 7% for campaigns using the full feature suite. Search Engine Journal recorded the same 7% figure when the sunset was first announced.

Independent tests are thinner. PPC Live's 2026 roundup reports that Smarter Ecommerce analysed more than 250 Search campaigns running AI Max and found a median revenue lift of 13%, close to Google's claim. The catch was "a median CPA increase of 16%". Only 22% of those campaigns came anywhere close to their original return on ad spend targets. A separate Brainlabs analysis of 23 tests across 16 mature accounts found that switching on all three AI Max features together carried a "40% higher success rate" than search term matching alone.

Read the ladder the way a fox reads a hedgerow: what is visible is not the whole field. Three of those four bars come from the vendor that sells the feature, and every one of them is a conversion or value figure. None is a profit figure. The independent bar is also a median across campaigns that were not randomly assigned, which is the honest caveat on all account-level AI Max data.

The other 78% either significantly over or underperformed, according to the same roundup. The spread matters more than the average. An average lift of 13% hides some accounts that gained a lot and some that lost, and the only way to know which you are is to read your own search terms, your own landing pages and your own cost per acquisition. That is exactly what a working AI Max reporting view would support, and exactly what you can start doing without one.

• 13%

  median revenue lift, per Smarter Ecommerce

• 16%

  median CPA increase in the same sample

• 22%

  of campaigns near their ROAS targets

• 40%

  higher success rate with all three features, per Brainlabs

One more note on sources. PPC Live is a secondary roundup, and its author's own single-account test (cost per acquisition up, clicks tripled) is anecdote, so we do not lean on it. The Smarter Ecommerce and Brainlabs figures are the ones with a stated sample. Where a primary write-up is behind a paywall or a bot wall, we cite the roundup and say so.

Five real checks before dynamic search ads are upgraded#

None of this needs the new report. It needs a spreadsheet, a fortnight and the discipline to write things down before the machine changes them. The point is to hold your own receipt when the vendor's arrives.

Start with the first. A baseline is the cheapest insurance in paid search, and it is the only thing you cannot rebuild after the account has moved.

The commercial version of this is a small, boring contract with yourself: what we will measure, what we will accept, and what we will switch off. If you want that built for an account, that is the kind of work our PPC team and our search and GEO practice do, and the AI Max explainer and the note on the automatic upgrade are the place to start reading.

Do the baseline this week. When the journey view arrives, you will know exactly how much of it you believe, and you will not need Google to tell you what the machine did with your money.
