About a year ago, I set up Google Ads conversion tracking for one of my clients
Everything had been working perfectly since then
Recently, the client reached out after noticing a "Needs Attention" warning inside Google Ads.
Their first thought was:
Has the conversion tracking stopped working?
Fortunately, that wasn't the case
The tracking was still recording purchase conversions correctly
The warning was actually related to Cost of Goods Sold (COGS).
Google Ads was receiving purchase events successfully, but some products in Google Merchant Center were missing COGS data.
That's why Google displayed the warning.
The good news?
This issue doesn't usually affect your conversion count or prevent conversions from being recorded.
However, it does reduce the quality of your profitability insights and gross profit reporting.
The fix was simple
We just needed to send the Cost of Goods Sold (COGS) value from the website's backend to Google Merchant Center as an additional product attribute
Once Google receives that data for all products, the warning is resolved
This is a great reminder that not every warning inside Google Ads means your tracking is broken
Sometimes your tracking works exactly as expected.
The platform is simply asking for better business data.
Understanding that difference can save a lot of unnecessary troubleshooting
