Google has just rolled out a fresh feature inside Google Ads that could make life easier for businesses running online stores. The new Conversions with Cart Data Diagnostics Tool is designed to help advertisers keep track of and troubleshoot the way their cart data is being sent to Google Ads.
If you run campaigns that rely on accurate sales and product information, this update could be a game-changer. It builds on Google’s standard conversion tracking, but instead of just recording when a purchase happens, it also looks at the finer details, such as which specific products were bought, their prices, and how many items were purchased.
This means you are not only tracking sales, but also getting a clear picture of what exactly is moving off your digital shelves. Stay ahead with Instagram Reels in 2025, see what’s trending next on Reels.
Why This Tool Matters for Online Advertisers
For anyone selling products online, tracking conversions is nothing new. You probably already measure how many sales you make and how your ads contribute to those sales. But standard tracking does not give you the full story.
Imagine you are running ads for ten different products. Without product-level data, you know a customer bought something, but you do not know whether it was your best-selling product or an item that has been sitting in your inventory for months. This gap in information can lead to wasted ad spend or missed opportunities to promote high-performing products.
The Conversions with Cart Data Diagnostics Tool solves this problem by digging into the details. It ensures that the data you send is complete and accurate so you can make better marketing decisions.
What the Tool Checks For
Google has outlined three main areas the tool focuses on:

1. Cart data is always sent with each purchase conversion
The tool checks whether product-level details, such as the item ID, price, and quantity, are actually being sent every time someone makes a purchase. If the data is missing, your reporting will be incomplete, and the tool will flag it.
2. Required product information is complete
Even if your cart data is being sent, it still needs to include all the important details. This includes the unique ID for each product, the price, and the quantity bought. If something is missing, the tool will let you know exactly what is wrong so you can fix it quickly.
3. Item IDs match those in Merchant Center
Your Merchant Center account contains the master list of products you sell. The tool will check whether the item IDs from your conversion data match the IDs in your Merchant Center. If they do not, you might see errors that could affect your ad performance.
How Advertisers See Their Results
Once the tool runs its checks, it gives you an overall status for your account. This status can be one of four levels:
- Excellent – Everything is working perfectly, and no issues are found.
- Good – Your setup is working well, but there may be minor areas to improve.
- Needs Attention – There are some problems you should fix to get the most out of your tracking.
- Urgent – Significant issues are preventing accurate data collection, and they need to be fixed right away.
This grading system makes it easy to understand at a glance how healthy your cart data tracking is. You do not have to be a tech expert to see where the problem lies, and Google provides alerts to guide you in fixing the issues.

Why Accurate Cart Data Is So Important
Accurate cart data does more than just make reports look nice. It impacts how your campaigns perform and how you make decisions.
When Google Ads has precise product-level data, it can:
- Improve sales reporting – You can see exactly which products are performing best, which helps with restocking and marketing strategies.
- Optimize campaigns more effectively – Google’s systems can better target ads towards the right customers if it knows which products are driving sales.
- Help you make smarter business decisions – Detailed insights can guide pricing strategies, promotional offers, and inventory management.
In short, having accurate data means you are not guessing. You are making decisions based on what is really happening in your store.
How This Fits into Google’s Bigger Picture
This new tool is part of Google’s ongoing push to help advertisers get more value from their data. Over the past few years, Google Ads has been adding more AI-driven features and automation tools that rely on high-quality input data.
The logic is simple: the better your data, the better Google’s algorithms can work for you. Inaccurate or incomplete data can confuse these systems, leading to wasted ad spend or missed opportunities. By giving advertisers a way to quickly check and fix their cart data, Google is aiming to improve both campaign results and user satisfaction.

What Advertisers Should Do Next
If you run an online store and use Google Ads, the first step is to make sure you have Conversions with Cart Data tracking set up. If you are not yet sending product-level data, it might be worth investing the time to implement it.
Once the setup is in place, use the Cart Data Diagnostics Tool regularly. Think of it as a health check for your conversion tracking. Even if everything seems fine, running diagnostics every now and then can catch issues before they start affecting your campaign performance.
It is also a good idea to make sure your Merchant Center is up to date. Old or incorrect product IDs can trigger mismatches that the tool will flag. Keeping your product feed clean and accurate will make the diagnostics process smoother.
Final Thoughts
Google’s Conversions with Cart Data Diagnostics Tool is a welcome addition for advertisers who want more control and clarity over their sales tracking. By highlighting problems in real time and showing clear action steps, it removes much of the guesswork from managing product-level conversions.
In an online marketplace where every click and conversion matters, having the right data at your fingertips can mean the difference between a campaign that just runs and a campaign that truly delivers. This new tool is Google’s way of helping advertisers make sure the numbers they are looking at are not just numbers, but reliable insights that can drive better business results.
