Many digital marketers have encountered a frustrating scenario: after meticulously optimizing Google Ads campaigns, products suddenly stop displaying properly due to a "CSS overload" warning in Google Merchant Center (GMC). While alarming, this appears to be a recurring technical glitch within Google's systems. Here are two practical solutions to address the issue.
Solution 1: Proactive Capacity Expansion Request
The most direct approach involves formally requesting increased capacity from Google. Follow these steps:
- Navigate to Google's capacity request form
- Provide accurate contact information for follow-up communication
- Include both your Google Ads and GMC account IDs for proper identification
- Select the appropriate issue category, specifically noting the CSS overload problem
- Detail your situation thoroughly, including the number of affected products
- Submit the completed request
Solution 2: Observation and Waiting
For less urgent situations, some users report the issue resolving spontaneously within 24-48 hours without intervention. While this passive approach may seem counterintuitive, documented cases suggest it can be effective for non-critical scenarios.
The CSS overload notification in GMC typically doesn't indicate a fundamental problem with campaign optimization. Marketers can choose between immediate action through official channels or temporary monitoring based on their operational timelines. Both methods have proven effective in restoring normal product visibility.
