Questions about backend search terms
How many bytes are allowed in Amazon backend search terms?
In the US store the search terms field is limited to 249 bytes. If you go over, Amazon may ignore the whole field, so staying under the limit matters more than using every byte.
Why do bytes and characters differ?
Letters without accents use one byte each. Characters such as ä, é or ß use two, and some symbols use more. That is why a field in German or French can reach the limit with fewer characters.
Should I repeat words from my title in the backend field?
No. Words already in the title or bullet points are indexed from there. Use the backend field for synonyms, other spellings and terms that do not fit naturally on the page.
