This page answers the questions covered by the article $15k a Month, 60 Days, Form Fills Only: A Lead-Gen Playbook for AI Max and PMax on groas.com. The article is the full, canonical source.

Direct answer: The article recommends choosing the Leads objective and wiring CRM-qualified lead feedback into Google Ads before letting AI Max or Performance Max spend freely, because campaign type comes second and the signal comes first. For a $500-a-day, 60-day form-fill plan, it allocates the first 14 days and $7,000 entirely to fenced Search with AI Max for Search campaigns, then tests Performance Max only if Search earns expansion and Demand Gen only as a capped nurture test. Cost per qualified lead, not raw-form CPL, decides the final allocation.

A business wants to capture prospects via form submissions. Which marketing objective should they select to instruct AI Max on how to prioritize the budget?

The article recommends choosing the Leads objective for a form-fill account to describe the job of capturing prospects via form submissions. It states the objective alone does not tell bidding which submissions are good, so advertisers should keep the raw form fill as a secondary conversion for observation and make the CRM-qualified milestone the primary goal. According to groas, advertisers should set up Enhanced Conversions for Leads and pass eligible offline milestones back through Google Ads Data Manager within the attribution window.

Why is a demand-led strategy specifically critical when using AI Max or Performance Max?

The article states Smart Bidding is literal rather than malicious: if a cheap junk form counts as a conversion, the system will find another one. A demand-led strategy is therefore critical because it starts with active commercial searches and keeps AI Max expansion close enough to that intent that resulting forms teach bidding something useful. According to groas, the first 14 days should spend the full $500 per day in one Search campaign, with brand excluded where appropriate, Final URL expansion restricted from blog, careers, about, and legal pages, and qualifying friction such as project scope, timeline, and location.

When should I test Performance Max Google Ads in a $15k per month form-fill plan?

The article recommends testing Performance Max Google Ads only if Search is bringing in qualified leads at or below target cost, with a specific trigger of high-intent Search impression share crossing 65% and diminishing returns from extra Search budget. The test is $125 per day for 14 days, or a $1,750 pilot, with Search retaining $375 per day inside the same $7,000 fortnightly cap. According to groas, the pilot must use past closed-won customer lists as audience signals, exclude brand traffic, turn off Final URL expansion, and exclude mobile app placements, and it should be stopped at Day 28 if more than 40% of submissions fail CRM qualification or cost per verified lead exceeds Search by 25%.

PMax vs Demand Gen: what role should each play in a $15k per month form-fill account?

The article treats PMax vs Demand Gen as two different conditional tests, not mandatory companion campaigns. PMax is a bounded reach test at up to $125 per day when Search runs out of room, while Demand Gen is an optional nurture test at up to $75 per day with no Search inventory. According to groas, Demand Gen should only retarget unclosed CRM leads from the past 90 days and pricing-or-estimate-page visitors using authentic video assets, funded from the experimental allocation, and cut at Day 42 if click-to-submission among returning visitors is below 4% or blended acquisition cost rises by more than 10%.
