Have you ever looked at a Performance Max campaign with an incredibly good ROAS, only to add the "New customer lifetime value" column and have a mini heart attack?

We've been there. When you see a massive New Customer (NC) value assigned in your account settings, it's easy to assume your primary Conv. value is artificially inflated. That would mean your actual revenue and ROAS are much lower than what the platform is reporting.

But before you start drastically adjusting bids or sending apology emails to your client, take a deep breath. Understanding how Google separates tracking from bidding—and understanding a crucial historical change to how this feature works—will save you a ton of grief.

1. The Historical "Gotcha": Why Veteran Media Buyers Get Confused

If you've been managing Google Ads for a while, your confusion is completely justified. You aren't crazy; the platform actually changed how this works.

Originally, you turned on New Customer bidding and assigned its value on individual campaigns. In that old setup, it was an all-or-nothing toggle. If you turned it on and assigned a value, it immediately started reporting that inflated value for that specific campaign.

However, Google recently moved the New Customer value definition to the Account Level. Because this value is now set at the account level, Google includes the reporting of new vs. returning customers by default across the whole account once you assign a value.

This UI shift fundamentally decoupled the background tracking from the active bidding algorithm, which leads us to how things work today.

2. Account-Level Tracking vs. Campaign-Level Bidding

To untangle the modern setup, we have to look at how Customer Lifecycle Goals are applied.

When you set up a New Customer Acquisition (NCA) goal now, you define two things at the account level:

• The Definition: What constitutes a "new customer" (identified via audience lists, your conversion tracking tag parameter, or Google's 540-day auto-detection window).
• The Value: The incremental monetary bonus assigned to a new customer's first purchase to signal their long-term value.

Because this is an account-level setting, Google is always tracking this data in the background and populating your reports, regardless of what your individual campaigns are doing.

3. The All-Important Campaign Checkbox

The magic (or the panic) happens at the campaign level. Under a campaign's Customer Acquisition settings, there is a specific checkbox: "Adjust your bidding to help acquire new customers."

• If Unchecked (Bid Equally): By default, a campaign bids equally for new and existing customers. The algorithm does not apply your account-level NCA bonus to the auction, and it does not inflate your primary Conv. value column.
• If Checked (New Customer Value Mode): Smart Bidding actively prioritizes new customers by adding your specified bonus value to a new user's purchase conversion. This is the exact moment your Conv. value and ROAS become artificially inflated to guide the bidding algorithm.

4. Why the "New Customer Lifetime Value" Column is a Tease

Many seasoned PPCers get tripped up because even when that campaign box is unchecked, the New customer lifetime value column still populates with a massive number in the reporting dashboard.

Why? Because, as mentioned above, Google's tracking is always on by default! It is essentially showing you a hypothetical adjustment. It observes the data and populates this column to show you what the added value would be if you were utilizing the feature to adjust bids. However, as long as that box remains unchecked, that hypothetical value is siloed; it is absolutely not baked into your main revenue columns.

5. The Ultimate Sanity Check: The "Original Conv. Value" Column

If you ever find yourself debating whether your ROAS is real or inflated by rules, Google recently introduced the perfect diagnostic tool: the Original conv. value metric.

This column displays the raw, unadjusted monetary value of your conversions before any value rules, lifecycle goals, or attribution changes are applied. It serves as a true baseline view of your conversion revenue.

How to use it:Place Conv. value and Original conv. value side-by-side in your dashboard.

• If they match exactly: Your campaign is reporting pure revenue. No NCA bonuses or value rules are inflating your numbers.
• If Conv. value is significantly higher: Your campaign is actively using an adjustment (like the New Customer Value mode), and your bidding algorithm is optimizing toward that inflated number.

The ZATO Takeaway

Google Ads makes this specific feature incredibly confusing by mixing account-level observations with campaign-level bidding activations, especially since it used to be an all-or-nothing campaign setting. The next time you see a high New Customer count in your reports but the "Adjust your bidding" box is unchecked, don't sweat it. Your reporting is safe. And when in doubt, let the Original conv. value column be your ultimate source of truth!

Google Ads New Customer Acquisition: Is Your ROAS Actually Real?

Picture this. You're looking at a Performance Max campaign with an incredible ROAS, feeling pretty good about yourself, and then you add the "New Customer Lifetime Value" column to the report and your stomach drops. The number is enormous. If that value is baked into your conversion data, your actual revenue is way lower than what the platform is showing you, which means your client's account is performing considerably worse than either of you thought.

We've written on this before, and it can really be a hit to the gut if it's actually artificually inflating your values (we wrote on this years ago here! Read This Before Using New Customer Acquisition Goals in Google Performance Max Campaigns).

HOWEVER, before you start adjusting bids or drafting uncomfortable emails, check this first, because it's now a little more complex than when this first began...

The Platform Changed How This Works (And That Could Be Why You're Confused)

If you've been managing Google Ads for a few years, your confusion here is completely justified. Back in late 2023, the platform changed how New Customer Acquisition works, and veteran media buyers got caught in the transition.

Originally, New Customer bidding was configured at the campaign level. You toggled it on, assigned a value, and that was it. The feature was live and immediately inflating your reported conversion value for that campaign. All-or-nothing, campaign by campaign.

However, in 2023, Google moved the New Customer value definition to the account level. That shift decoupled the background tracking from the active bidding algorithm, which is the root of all the confusion.

Most people never got a clean explanation of what that change actually meant in practice, so let me give my best shot:

‍

Account-Level Tracking vs. Campaign-Level Bidding

When you set up a New Customer Acquisition goal today, two things happen at the account level.

First, you define what constitutes a new customer. Google identifies them through your audience lists, your conversion tracking tag parameter, or its own 540-day auto-detection window. Second, you assign an incremental monetary bonus to a new customer's first purchase, a value signal meant to communicate their long-term worth to the bidding algorithm.

Because this is now an account-level setting, Google is always tracking new versus returning customer data in the background and populating it in your reports, regardless of what any individual campaign is doing. That last part is the thing people miss.

‍

‍

The Checkbox That Actually Controls Everything

Inside any campaign's Customer Acquisition settings, there is a single checkbox that determines whether the NCA value affects your bidding: "Adjust your bidding to help acquire new customers."

When that box is unchecked, the campaign bids equally for new and existing customers. The algorithm does not apply your NCA bonus to the auction. Your primary Conv. value column is not inflated. The numbers you're looking at reflect actual revenue.

When that box is checked, Smart Bidding starts adding your bonus value to new customer purchases to guide the algorithm toward prioritizing them. Your Conv. value and ROAS become intentionally inflated as a bidding signal. That's working as designed, but it does mean you can't read those columns as straight revenue figures anymore.

However, it gets even more technical, based on what we've seen, it's when that box is ticked AND THEN it is also set to "Bid Higher for newer customers" where you can then see the goal value you've set.
‍

This is exactly the kind of campaign setting detail that causes real confusion in audits, especially when you're inheriting an account and trying to quickly understand whether performance numbers are trustworthy.

‍

Why the Column Populates Even When the Box Is Unchecked

Here's the thing that trips people up. Even when the bidding adjustment box is unchecked, the New Customer Lifetime Value column still shows a large number in your reporting dashboard, but it is NOT ACTUALLY CHANGING YOUR CONV VALUE COLUMN OR INFORMING YOUR BIDDING.

You can confirm this, by comparing your Original conv. value column. If that matches your Conv value, then the algorithm is NOT bidding according to your set New Customer values, and it is also not inflating the conv value column! Your LTV column is simply reporting what COULD be if you had that box checked.

Since Google's tracking is always on for this value, the column is showing you a hypothetical: here's what the added value would look like if you were using the feature to adjust bids. It's observational data, not active bidding data. As long as that checkbox remains unchecked, the number in that column is siloed from your main revenue columns entirely.

This column shows your raw, unadjusted conversion value before any value rules, lifecycle goals, or attribution changes are applied. Put Conv. value and Original conv. value side by side in your dashboard.

If they match exactly, your campaign is reporting pure revenue. Nothing is being inflated.

If Conv. value is significantly higher than Original conv. value, your campaign is actively using an adjustment and your bidding algorithm is optimizing toward an inflated number.

BTW, this is useful well beyond the NCA question. Any time you're running value rules or trying to understand whether conversion tracking adjustments are affecting your reported numbers, Original conv. value is where you go first.

Now, IMO Google could do a better job of making that distinction obvious. It doesn't. Which is why this specific feature generates so many panicked Slack messages.

Final Note

This particular feature is a little confusing by mixing account-level observation with campaign-level activation, and the historical change from campaign-level to account-level setup means a lot of experienced practitioners are working from outdated mental models of how it behaves.

When you see a large New Customer count in your reports and that bidding adjustment box is unchecked, your data is fine. The column is telling you what could happen, not what is happening. And when there's any doubt at all, Original conv. value is your ground truth.
