Why Are Search Terms So Important?
Search terms are the hidden part of your Amazon listing – the only part competitors cannot 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 maximise 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.
