01/04/2021 • Reading time: ca. 2 min • by Trutz Fries


On Amazon, relevant keywords can be used in the title, in the bullet points, in the product description and as so-called backend keywords. Backend keywords are keywords that are not visible to the customer on Amazon but are indexed by Amazon's search. These keywords are stored Seller or Vendor Central in the context of a product under the item General Keywords. Next to the title, the backend keywords are the second most important keyword source. They are perfect for colloquial keywords, outdated spellings or for typical typos (e.g. addidas instead of adidas), which you cannot accommodate in the product text.

Amazon Guidelines: What rules should you follow for backend keywords?

For the backend keywords you have a total space of 249 bytes.

Difference bytes and characters
in text characters does not always correspond to one byte. So the letter "a" is one byte, but the letter "ä" is already two bytes.

Amazon also issues a few more prohibitions:

  • ASINS must not be used in the backend keywords.
  • Offensive vocabulary and terms should be avoided.
  • No false claims or subjective statements may be made. This includes terms such as "beautiful" or "cheap".
  • In addition, temporary statements such as "Now on sale" should be omitted. Third-party brands may not be deposited.
