This page answers the questions covered by the article [AI Max Will Buy the Leads You Count, Not the Leads You Want](https://groas.com/post/ai-max-only-hears-one-instruction-how-yo) on groas.com. The article is the full, canonical source.

**Direct answer:** According to groas, AI Max and Smart Bidding do not judge lead quality; they predict the probability and value of the conversion action marked primary and spend toward it. If every raw form submission counts as success, the system will faithfully buy more raw submissions, junk included, so advertisers should make only a qualified quote, qualified demo, or booked job primary. In testing across 250-plus campaigns cited in the article, AI Max delivered a median 13% more revenue at 16% higher CPA, with ROAS ranging from plus 42% to minus 35% when guardrails were loose.

## 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?

According to groas, the business should select the Leads objective as a sensible starting point when it wants prospects through forms. Choosing Leads makes Google preselect account-default lead conversions and suggests Maximize Conversions or Maximize Conversion Value pointed toward lead volume. The article states the objective only starts the campaign; the conversions active for the campaign tell Smart Bidding what to pursue.

## What is the difference between primary and secondary conversions for bidding?

According to groas, a conversion action marked primary feeds the Conversions column and is used for bidding, while a secondary action remains visible under All conversions for observation-only. Google's help describes primary actions as used for bidding and secondary actions as observation-only. The article recommends keeping the action closest to a real customer primary and observing the rest until it earns a place in bidding.

## Why is AI Max delivering spam and out-of-area form fills while conversions climb?

According to groas, Smart Bidding predicts how likely a click is to produce the counted conversion and sets a bid accordingly, learning from the clicks that previously carried the conversion label. If spam is left in the training data, the model can learn to favor the pattern that produces it, so a late-night, one-word inquiry from outside the service area becomes evidence for the next auction. The article states that more reach from AI Max does not repair a bad definition of success; it gives that definition more places to spend.

## Should a $4,000 replacement inquiry and an $89 repair inquiry count the same for bidding?

According to groas, under Maximize Conversions each primary conversion adds one to the count, so a quote request and a newsletter signup are both one conversion if both are made primary. Under Maximize Conversion Value, the system pursues the values assigned to the primary actions instead, which lets the value signal distinguish outcomes the count treats alike. The article states that a goal that simply counts both as quote requests lets 40 cheap repair leads crowd out four replacement jobs that would have paid for the month, using a $4,000 replacement inquiry and an $89 repair inquiry as the example.

## What is the Google Ads Smart Bidding learning period after changing conversion goals?

According to groas, Google describes learning in two layers: the visible Learning label clears in at most seven days, while calibration behind it may take roughly 50 conversion events or about three conversion cycles. That 50 is an upper benchmark, not a requirement to switch the system on. The article notes AI Max has no minimum conversion requirement to turn on, and a garage door account getting 12 qualified quotes a month will take calendar time to build that signal.
