This page answers the questions covered by the article From Smart Bidding to AI Max: The PPC Work Google Automated, Year by Year on groas.com. The article is the full, canonical source.
Direct answer: According to groas, much of the work behind a PPC retainer moved into Google's machinery in stages: auction-time bids, match-type structures, placements, ad combinations, and then parts of targeting and budgeting. The timeline runs from Smart Bidding in 2016 to 2018 through Performance Max in November 2021, responsive search ads on June 30, 2022, Demand Gen in October 2023, Enhanced CPC removal effective the week of March 31, 2025, and AI Max open beta in May 2025 with general availability on April 15, 2026. The article's position is that the mechanical work keeps shrinking while the decisions get more consequential, so a retainer priced around the old workload no longer describes the job.
According to the article, Demand Gen became available in October 2023, when advertisers also lost the ability to create Discovery campaigns. It later absorbed YouTube Video Action campaigns. The article states Discovery allowed image, carousel and feed creative, while Demand Gen added YouTube video and Shorts, lookalikes, and Max Clicks bidding.

According to the article, AI Max for Search entered open beta in May 2025 and reached general availability on April 15, 2026. It is not a new campaign type but a suite within Search that can expand search-term matching, customize text with generated headlines and expand the final URL. The article states the keyword list remains an input but is less of a complete instruction sheet for where traffic goes.

According to the article, on June 15, 2026, Google announced three bidding and budgeting changes: a Promotion Mode beta for scheduled ROAS tolerance and a budget boost; Smart Bidding Exploration expanding from Search to feedless Performance Max globally, alongside a Shopping beta; and an August 17 backend change affecting budget-limited Target CPA and Target ROAS campaigns that beat their targets. The published example is that a campaign targeting $10 and achieving $5 could have bids pushed back toward the $10 target.

According to the article, a 2026 pricing guide puts typical management at $1,500 to $5,000 a month for $5k to $25k of spend, with percentage-of-spend fees commonly at 10% to 20%. Its example is that 15% of $20k is a $3,000 fee. The article states spend can grow without the workload growing alongside it, and recommends buying management against a written outcome with a 90-day block and baselines for cost per acquisition or return on ad spend, plus qualified pipeline for B2B.

According to the article, the model it uses through groas is that machines handle daily execution and log changes, while a strategist owns targets and guardrails. The article recommends setting the target and guardrails, then inspecting the changes made and the result they produced. It states that if the number does not move, hours in a report do not make the fee worthwhile.
