Here are some best practices for providing keywords:

Don’t provide inaccurate, misleading, or irrelevant information such as competitor product, brand or author name, wrong gender, etc. Providing misleading or irrelevant information is against Amazon policy; your listing will be removed and your account will be suspended . Moreover, your product might end up in a wrong browse node and your sales might get affected.
Don’t provide excessively long content. Providing overly long content can violate Amazon selling policy. For more information, please see Prohibited Seller Activities and Actions. Respect the limits that are set for different fields.
Don’t provide redundant information that is already captured in other fields such as title, author, product description, bullet points, brand, etc. It won’t improve your product placement in search results.
When entering several words as a search term, put them in the most logical order. A customer is more likely to search for big stuffed teddy bears than for teddy stuffed bears.
Use a single space to separate keywords. No commas, semicolons, carets are required.
Don’t include statements that are only temporarily true, e.g., “new,” “on sale,” “available now”.
Don’t include subjective claims such as amazing, good quality. etc., as most customers don’t use subjective terms in their queries.
Don’t include common misspellings of the product name. Amazon’s search engine compensates for common customer misspellings and also offers corrective suggestions.
Don’t provide variants of spacing, punctuation, capitalization, and pluralization (“80GB” and “80 GB”, “computer” and “computers”, etc.). Our search engine automatically includes different case forms, word forms, and spelling variants for searching.
Don’t include terms that are abusive or offensive in nature.
Abbreviations, alternate names, topic (for books etc.), and key character (for books, movies etc.) could be included as keywords.
