AI Max Reporting & the DSA Transition: 2026 Guide

What did Google actually change about AI Max reporting and DSA?

Google confirmed in April 2026 that AI Max for Search campaigns will replace Dynamic Search Ads (DSA) entirely, refreshed the reporting inside AI Max, and then delayed the forced migration. The automatic upgrade of DSA campaigns moved from September 2026 to February 2027, and Google restored the option to create new DSA campaigns on June 15, 2026. So the headline is calmer than the early panic suggested: you have a longer runway, but the destination is unchanged.

For SEO and search teams, two things matter here. First, the reporting layer changed in ways that affect how you read query data and attribute conversions. Second, the migration timeline reshuffles your planning calendar. This guide covers both, plus the controls most rushed write-ups skip.

The DSA-to-AI Max timeline: what actually changed

The original message implied a hard cutover in late 2026. The revised plan is more forgiving, and the dates are worth pinning down because agencies have been quoting the old ones.

• April 15, 2026 — Google confirms AI Max for Search will replace DSA. AI Max becomes the long-term home for the 'find me untapped queries from my landing pages' behavior DSA pioneered.
• June 15, 2026 — Creation of new DSA campaigns is reinstated, reversing the earlier phase-out step. You can still spin up a DSA today.
• Through 2026 — Both DSA and AI Max run in parallel. This is your testing window.
• February 2027 — Remaining DSA campaigns begin auto-migrating to AI Max (or to Search campaigns using broad match and Smart Bidding). New DSA creation winds down ahead of that.

The delay is a reprieve, not a reversal. Treat the extra months as paid time to learn AI Max's reporting on your own terms, before an automatic migration decides your settings for you.

What most timeline posts get wrong: they frame February 2027 as the deadline. It is the start of an automatic process, not a do-it-by date. The teams that win here migrate before the auto-upgrade, because a manual move lets you keep your structure, set controls deliberately, and benchmark performance instead of inheriting Google's defaults.

How is AI Max different from DSA in practice?

DSA matched ads to queries by crawling your site and generating dynamic headlines. AI Max keeps that instinct but widens the inputs and adds steering controls. The table below maps the practical differences for anyone reporting on the switch.

Google's own data point: campaigns using the full AI Max suite — search term matching, text customization and final URL expansion together — average about 7% more conversions or conversion value at a similar CPA or ROAS than those using search term matching alone. The lesson is not 'turn it all on blindly,' but that half-configured AI Max underperforms its own ceiling.

Reading the new AI Max reports without getting fooled

The reporting refresh is where SEOs and analysts should spend their attention, because broader matching means more queries you did not explicitly choose. AI Max exposes four reports that matter: the search terms report, the keyword report, the asset report and the landing pages report.

The standout addition sits at the top of the search terms table: a view called 'Search terms and landing pages from AI Max.' It lists the queries that triggered your ads alongside the exact headlines, landing pages, campaigns and ad groups that formed each customer's path. In other words, it finally answers 'which query went to which page, and did that pairing make sense?' — a question DSA reporting left fuzzy.

Three reporting traps to watch

1. Query bloat looks like growth. AI Max surfaces more long-tail queries, so impression and click volume rises. Judge it on conversion value at target CPA/ROAS, not raw query count.
2. Landing page mismatches hide in aggregate. Use the combined view to spot queries routed to a weak or off-topic page. Final URL expansion is powerful but needs auditing in the first few weeks.
3. Brand and competitor terms leak in. Without inclusions/exclusions set, broader matching can spend on queries you would never have bid on manually.

This is also where cross-checking paid query data against your organic visibility pays off. Pulling AI Max's expanded search terms next to your organic SERP tracking in Sentinel SERP shows which newly matched queries you already rank for organically — so you can decide where paid spend genuinely adds incremental reach versus where it overlaps free traffic you already own.

Controls that protect your brand and budget

AI Max's reputation for 'going wide' is fair only when you skip its controls. Three levers do most of the work:

• Brand inclusions restrict search term matching so your ads only show when a query contains your specified brand terms — useful for branded-only campaigns.
• Brand exclusions stop your ads appearing on competitor or unrelated brand names, the single most common source of wasted AI Max spend.
• Text guidelines steer the auto-generated and customized copy so it stays on-message, with location controls tightening geographic intent.

Set these before you let final URL expansion run loose. A practical order of operations: enable search term matching with brand exclusions in place, review the combined report for a week, then add text customization and final URL expansion once you trust the query mix. That staged rollout is how you capture the ~7% upside without the early overspend horror stories.

Your migration checklist for the next six months

With the auto-migration not landing until February 2027, the smart play is a deliberate manual move well ahead of it. Work this sequence:

1. Inventory your DSA campaigns. Note targets (page feeds vs whole-site), top converting queries and current CPA/ROAS as your baseline.
2. Build a parallel AI Max test. Mirror a strong DSA campaign so you compare like for like rather than guessing.
3. Configure controls first. Brand exclusions, location controls and text guidelines go in before you scale spend.
4. Audit the combined report weekly. Kill bad query-to-page pairings early using final URL expansion controls.
5. Benchmark against organic. Map AI Max's new queries to your organic rankings so you fund incremental reach, not cannibalized clicks.
6. Migrate on your schedule. Move budget over once AI Max matches or beats your DSA baseline — not when the calendar forces you.

The publishers and analysts who treat the February 2027 date as a starting gun, not a finish line, will enter the forced migration with clean structure, proven controls and reporting they already understand. That is the entire advantage Google's delay just handed you.
