Smart Bidding and the Bid Cap: How Maximize Conversions Changes What Google Ad Grants Can Reach

Two dollars a click. That is the ceiling on manual bidding in a Google Ad Grants account, and it is the reason so many grant ads sit near the bottom of the page or never show at all.

There is a setting that lifts it. Google now requires most Ad Grants accounts to use conversion-based Smart Bidding, and under strategies such as Maximize Conversions the cap no longer applies. Google bids what it predicts a conversion is worth, which changes which searches your mission can reach. Here is how the cap works, what Smart Bidding does with it, and what the account needs before the switch pays off.

What the bid cap is, and why it matters

Commercial advertisers can bid whatever a click is worth to them. On manual bidding, an Ad Grants account cannot bid more than 2 dollars for a click. For low-competition searches that is enough. For the searches that matter most to many missions, such as help for a family in crisis in a large city, or a cause that commercial services also advertise against, paid advertisers routinely bid several times that amount. A capped bid loses the auction, the ad shows lower or not at all, and the daily budget goes unspent. Our article on why most of the Ad Grants budget goes unspent lists the cap as one of the five causes.

What Google now requires

Google's account management policy requires accounts created on or after April 22, 2019 to use conversion-based Smart Bidding on every campaign, unless the account uses only Smart campaigns. The permitted strategies are Maximize Conversions, Maximize Conversion Value, Target CPA, and Target ROAS. Campaigns that do not comply are subject to automatic bid strategy changes, and the account can be deactivated for bidding. Older accounts are not required to switch, but the cap still applies to them on manual bidding, so the same logic holds: the switch is how the account reaches searches it cannot reach today.

The bid cap is not the limit on your reach. Manual bidding is. Smart Bidding is the setting that changes what the grant can do.

How Smart Bidding lifts the cap

Smart Bidding sets a bid for every auction based on the likelihood that the click becomes a conversion. When Google predicts that a search is likely to lead to a donation, a sign-up, or a call, it can bid above 2 dollars to win it. When it predicts the opposite, it bids low or sits the auction out. The daily budget is the same. What changes is where it goes: away from cheap clicks that lead nowhere, toward the searches that produce the actions you track.

That last phrase is the whole condition. Smart Bidding can only learn from conversions it can see. An account with no conversion tracking, or tracking that counts page views instead of actions, gives the strategy nothing to learn from or teaches it the wrong lesson. The conversion tracking requirement and the bidding requirement are the same requirement seen from two sides.

Which strategy to choose

• Maximize Conversions. The default for most nonprofits. It spends the budget to get as many tracked actions as possible. Start here.
• Maximize Conversion Value. For accounts that assign values to conversions, such as donation amounts, so the strategy favors higher-value actions.
• Target CPA and Target ROAS. For accounts with a lot of conversion history that want to hold a cost per action or a return. Most small organizations do not have the volume for these to work well.
• Maximize Clicks. Google allows it as a starting point while tracking is being set up and the first conversions come in. It is a bridge, not a destination, because it does not lift the cap.

Google suggests that fifteen to thirty conversions in the last thirty days is a reasonable starting point for a conversion-based strategy to learn. Below that, expect a longer learning period and uneven results. The fix is more tracked actions, not a different strategy: add the small conversions such as email sign-ups and information requests alongside the donation.

What to expect after the switch

The first weeks are a learning period. Spend and results move around while the strategy tests bids. Resist the urge to change settings daily; give it several weeks and judge it on conversions, not on click-through rate alone. Watch two things. If spend rises but conversions do not, the conversion actions are probably too loose, and you are paying for clicks that look like results. If spend stays flat, the campaigns may be starved of keywords or held back by low quality scores, which no bid strategy can fix. Our articles on choosing keywords and campaign structure cover both.

The mistakes that undo it

• Switching before tracking works. The strategy learns from whatever it sees. Confirm real conversions are recording first.
• Counting the wrong things. Page views and button clicks marked as conversions teach Smart Bidding to buy traffic that never becomes support, and an inflated conversion rate draws Google's review.
• Setting targets too tight. A Target CPA the account has never achieved tells the strategy to sit out most auctions.
• Judging it in week one. The learning period is real. Change one thing at a time and give each change time.
• Leaving campaigns on manual bidding. On accounts created since April 2019 that is a policy violation, and Google may change it without asking.

Questions nonprofits ask about Smart Bidding and the cap

Does Smart Bidding spend more than the grant allows?

No. The monthly award is the ceiling. Smart Bidding changes how the daily budget is distributed across auctions, not the size of it.

Can we keep manual bidding to control costs?

If the account was created on or after April 22, 2019, manual bidding is out of policy. Older accounts may keep it, but the 2 dollar cap keeps them out of the searches that matter most.

Why did our bid strategy change without us touching it?

Google's policy states that non-compliant campaigns are subject to automatic bid strategy changes. Treat it as the notice that the account needs conversion tracking that works.

How long until Smart Bidding performs?

Google does not promise a timeline. Plan on several weeks of learning, and expect faster results in accounts that record dozens of conversions a month rather than a handful.
