When a person is looking for something on the internet, s/he types a single word, called “keyword”, or a phrase, called “keyword phrase”.
This is the same for the search field on Amazon when customers want to buy something.
The most important keyword, which best describe your product, must be placed on your listing headline.
You can also include keywords or keyword phrases on your bullet points.
On your Amazon Seller Central, you can add more keywords, images, and all other data at the backend.
This is maximum of 250 characters, no commas, and no need to repeat words.
Keywords will help you gain visibility, which will lead to sale. You have to identify the most relevant, most searched, and lowest competition keywords for your product and add it to your headline, bullets, and backend.
This tells Amazon what product you are selling and on which keywords you need to register your product.
You can also use different techniques for your keywords like misspellings, other brand names, and seasonal keywords like “Prime Day”, “Thanksgiving”, “Christmas”, “New Year”, etc.
