Excessive capitalization: how to fix it

What triggers the "Excessive capitalization" error in Merchant Center and how to fix a title or description written in all caps.

Plain-English summary

"Excessive capitalization" means your title or description is written in ALL CAPS or over-capitalised in a way that reads as shouting or spam. Rewrite it in standard sentence or title case.

What triggers it

Google treats a title or description written entirely (or mostly) in capital letters as a policy signal, since all-caps text reads as shouting or as an attempt to grab attention unfairly in the results grid, and it's a pattern strongly associated with spam listings. It often comes from a source system that stores product names in uppercase for internal reasons (a legacy ERP, a supplier feed) rather than a deliberate choice.

If the whole catalogue is affected, check the source field's casing before rewriting titles by hand, since the fix usually belongs upstream.

/tools' enrichment writes titles and descriptions in proper case as standard, so feeds pulled from all-caps source systems don't carry the formatting through to Google.

Step by step

  1. Find the affected products. Filter Diagnostics to "Excessive capitalization" and check whether it's isolated products or a whole feed export set to uppercase.
  2. Rewrite in standard case. Use sentence case or title case (capitalise the first letter of each significant word), the way you'd naturally write it for a shopper.
  3. Keep legitimate acronyms and brand names as-is. Genuine acronyms (USB, LED) and brand names that are properly capitalised aren't the problem, wholesale shouting is.
  4. Resubmit. Push the corrected feed. This is a data fix and clears on the next crawl.
