This page answers the questions covered by the article Discovery, Demand Gen and Performance Max: The Timeline Behind Google’s Campaign Consolidation on groas.com. The article is the full, canonical source.
Direct answer: According to groas, Demand Gen replaced Discovery ads after Google announced Demand Gen on August 15, 2023, with general availability in October and auto-upgrades of remaining Discovery campaigns from January to March 2024. After successive consolidations, Performance Max can harvest existing Search and Shopping intent across Search, Shopping, YouTube, Display, Discover, Gmail and Maps, while Demand Gen builds interest through visual feeds and video without Search results. The article recommends separating brand from non-brand and channel splits in reporting, giving Demand Gen sufficient budget and four to six weeks to learn, and auditing guardrails rather than defending old campaign labels.
According to groas, Demand Gen is what replaced Discovery ads: Google announced Demand Gen on August 15, 2023, with beta sign-up immediately and general availability in October, then auto-upgraded remaining Discovery campaigns from January to March 2024 with history and learnings retained. The article states this was not a simple rename, because Demand Gen kept the Discover feed, Gmail Promotions and Social tabs, and YouTube Home base while adding YouTube Shorts, in-stream, YouTube Search and more video inventory, plus video assets, carousel and portrait and square formats, Lookalike segments, Max Clicks, previews and A/B experiments.

According to groas, Performance Max can reach across Search, Shopping, YouTube, Display, Discover, Gmail, Maps, search partners and Waze for store goals, while Demand Gen is built around visual inventory: YouTube in-feed, in-stream and Shorts, Discover, Gmail and Display, plus Maps in beta, but not Search results. The article states Demand Gen offers Lookalike segments built from first-party lists, audience-level reporting and channel exclusion, while PMax has less creative control and no comparable channel exclusion even as its reporting improves. The working distinction is that PMax can harvest existing search and shopping intent and Demand Gen can build interest through feeds and video.

The article recommends treating Demand Gen as a layer added after a stable Search, Shopping or PMax base, not a starter campaign, with working guidance of 15 times target CPA per day, or 20 times average value divided by target ROAS, with four to six weeks of learning. According to groas, if spending, say, $20k a month with thin creative, skip Demand Gen until the base is solid. If inherited on Monday, the article recommends separating Search and Shopping intent, PMax channel splits and Demand Gen placements without letting brand demand flatter results, checking budget, time and image and video assets, and writing down brand exclusions, negatives, conversion values and creative requirements.

According to groas, Smart Shopping campaigns were auto-upgraded to Performance Max from July through September 2022, with Local campaigns following in August and September, and advertisers could no longer create either old campaign type afterward. The article states history and learnings carried over while the old structure did not. It recommends measuring what wider inventory adds, separating brand from non-brand in assessment, and not mistaking blended ROAS for proof that every part of the campaign was equally productive.

According to groas, on April 30, 2025, Google announced channel performance reporting, plus fuller search-term and asset reporting for PMax, with channel reporting entering open beta from May. It broke out spend, clicks, impressions and conversion value by channel and format. The article states reporting does not become a steering wheel because advertisers still cannot exclude PMax channels the way they can in Demand Gen, but it should be used to check which channels spent, which produced conversion value, and whether strong CPA depends on Search and Shopping.

According to groas, a migration tool began rolling out in June 2026 to move existing standalone Display campaigns into Demand Gen, with 42 days of performance history ported over, and the full migration is expected to finish by 2027. The article states the Google Display Network itself is not disappearing; Display stops being its own campaign type and becomes a channel inside Demand Gen, with Demand Gen channel controls for Display-only intent. It recommends planning around inventory, creative and measurement rather than protecting a separate Display label.
