Merchant Center Diagnostics & Feed Health

Merchant Center Diagnostics in MerchantFlow is the monitoring dashboard that tracks your Google Merchant Center product approval status, identifies disapproved products, and helps you resolve feed issues to keep your items live on Google Shopping. Disapproved products generate zero impressions and zero revenue, so fast issue resolution directly impacts your bottom line.

What Is Merchant Center Diagnostics?

Google Merchant Center hosts your product data for Google Shopping. Products must be approved before showing in search results.

Merchant Center Diagnostics in MerchantFlow lets you:

• Monitor product approval status across your entire catalog
• Identify disapproved products and understand rejection reasons
• Track feed quality score metrics over time
• Resolve issues quickly with guided fix workflows
• Maintain high approval rates to maximize Shopping visibility

Why diagnostics matter:

Disapproved products:

• Do not show in Google Shopping
• Generate zero impressions or clicks
• Lose potential revenue every day they remain unapproved
• Hurt overall feed quality score

Quick issue resolution:

• Gets products live faster
• Maintains high feed quality
• Maximizes Shopping visibility
• Increases revenue potential

Score factors:

• Issue severity (critical issues hurt more)
• Data completeness (percentage of optional fields filled)
• Image quality
• Feed freshness (recent updates)

View score: Dashboard > Merchant Center > "Feed Quality" panel

Best Practices for Merchant Center Health

1. Monitor Daily

Quick daily check:

• Takes 2 minutes

Why: Catch issues fast, minimize revenue loss.

2. Fix High-Volume Products First

Prioritize by revenue:

• Fix best-sellers first
• They generate most revenue
• Biggest impact from resolution

Example:

• 100 products disapproved
• Top 10 = 60% of revenue
• Fix those 10 first

3. Set Up Disapproval Alerts

Get notified of issues:

1. Go to Settings > Notifications
2. Enable "Merchant Center Alerts"
3. Set:
   • Alert when approval rate drops below 90%
   • Daily summary of disapprovals
   • Critical issues notification
4. Save

4. Complete All Product Data

Even optional fields:

• Brand
• Color
• Size
• GTIN (when available)
• Condition (new/used/refurbished)
• Age group
• Gender

Why: Higher approval rate, better quality score, improved Shopping performance.

Image checklist:

• At least 800x800 pixels
• White or neutral background
• Shows full product clearly
• No watermarks
• No promotional text
• Multiple angles (optional but recommended)

6. Keep Feed Fresh

Regular updates prevent:

• Expiring products

Set automatic syncs: Dashboard > Settings > Sync Schedule

7. Review Google Policies Regularly

Stay compliant:

• Read Shopping Policies

All Products Disapproved

Causes:

• Account suspended
• Major policy violation

Quality Score Not Improving

Review:

Action: Focus on critical issues first, work through systematically.

Frequently Asked Questions

How long does it take for Google to approve a product after fixing an issue?

After you fix a disapproved product and resubmit through a sync, Google typically re-reviews and approves within 1-2 business days. New accounts may take up to 7 days. If approval takes longer than 3 days, try requesting a manual review.

What is a good product approval rate for Google Merchant Center?

Aim for a 95% or higher approval rate. Below 90% indicates significant feed quality problems that are costing you revenue. Focus on fixing disapproved products with the highest revenue potential first.

Do I need GTINs for all my products?

Not all products require GTINs. Custom-made, handmade, vintage items, and product bundles you created are exempt. For brand-name products with manufacturer barcodes, GTINs are required. Set identifier_exists = false for exempt products.

How does MerchantFlow help compared to checking Merchant Center directly?

MerchantFlow consolidates your Merchant Center diagnostics alongside revenue data, so you can prioritize fixes based on revenue impact rather than just issue count. It also provides guided fix workflows, bulk resolution tools, and alerting that Google Merchant Center's native interface does not offer.
