There is an Amazon HTML ban coming into force on the 8th of June 2021, which will end the use of any HTML on product detail pages. Amazon already strongly discourage the use of HTML but the 8th of June is the final day where any will be allowed.
Amazon say that this is for two reasons – In order to provide security for our customers as well as versatility to list products on non-HTML devices.
It’s debatable how many merchants the Amazon HTML Ban will actually impact, for most merchants it’s likely that you have no HTML on your product detail pages anyway. However if you have inserted HTML in your descriptions then you will need to remove it before June. If an HTML tag is used in any line of a product description, the line will be removed or shown without HTML formatting, depending on the usage of the tag from the 8th of June.
Amazon HTML Ban special use case
As a special case, you can use line breaks (</br>) as necessary in the description.
Amazon also remind merchants to comply with the relevant style guide for the product you are listing. You can find links to all Amazon style guides for UK listings here.
