The module automatically sends keywords to Amazon.
The module takes keywords present on the product sheet in Information tab, Keywords (tags):
On previous versions of PrestaShop, the module takes the keywords from SEO tab, Keywords (Meta Keywords).
And sends them on Amazon in the appropriate fields:
Note that it is often required that the keywords are spread over 5 lines, this use is unnecessary and does not match any recommendation from Amazon. The module will distribute the keywords on 5 lines depending on the number of keywords and the maximum size of the target field. There is no need to contact us about it and if you challenge the module’s operating principle on this point, please do it with a written letter from Amazon, this sentence would be longer exist and the module would be modified consequently.
