The Amazon Keyword Tool uses Amazon's autocomplete service or suggest service to find popular Amazon keywords directly from Amazon in real-time.
Amazon's Autocomplete service (example shown below) is a technical term used for the Amazon keywords and suggestions you see when searching for products using Amazon keyword search.
This service is intended to speed up your search interaction by trying to predict what product you are searching for on Amazon.
Keyword Tool Dominator unlocks the autocomplete service with the Amazon Keyword Research Tool by emulating a real human user and repeatedly typing in hundreds of search terms into Amazon.
Each time a search term is typed, Amazon provides a list of predictions (Amazon SEO keywords and long tail keywords) of what it thinks you are searching for.
Keyword Tool Dominator then simply extracts all of these predictions and presents them to you.
For each Amazon keyword search - up to 300+ related keyword suggestion could be extracted.
And most importantly, each keyword suggestion is assigned a calculated popularity keyword rank score.
Keyword rank values can range from 1 to 10, which represents the search popularity of a given keyword relative to the other keyword suggestions found.
Finally, Keyword Rank is derived using a proprietary calculation leveraging data extracted from each keyword and the keyword group; including the position of the keyword, word count, and word frequency.
