Amazon Search Terms Character Limit Checker

If you’re an Amazon seller, optimising your search terms is crucial for your product’s visibility and success.

Amazon has specific character limits for search terms, and exceeding these limits can result in Amazon ignoring all of your valuable search terms. Use our free Amazon Search Terms Character Limit Checker to ensure your search terms comply with Amazon’s guidelines.

Why Are Search Terms So Important?

Search terms are a hidden but powerful part of your Amazon listings - they’re the only part that competitors can’t see and copy! Combined with your product title and bullet points, they determine when customers will see your organic listings.

Amazon’s Search Terms Guidelines

Amazon has specific guidelines for search terms across all marketplaces:

• Use singular or plural forms (choose the shorter version to maximize space)
• Separate words with spaces
• Don’t repeat words that already appear in your title or bullets
• Stay under the character/byte limit (typically 250 bytes)

In some countries, Amazon explicitly states: “If Search Terms are over the limit, NONE of the Search Terms for that ASIN will be indexed by Amazon Search”

How Does Amazon Measure Search Terms Length?

Amazon generally measures length in bytes. While this is usually the same as character count, letters with accents can count as 2 or even 4 bytes. Our checker shows both character count and byte count to ensure compliance.

Use this tool regularly when updating your listings to maximize your product’s visibility in Amazon’s search results.
