I am working on an Amazon Keyword Research Tool (I am a developer). I know that there are many of these tools around, but I have not been able to find one that does everything I would like to have in one product.
I wonder if I could ask you look at these features and comment/suggest ideas?
Basically, the way I see that type of keyword research is that it needs to start with Google keywords, not Amazon! The reason is that your clients are going to be coming from Google (if they are on Amazon they are not in your site).
Step 1 is to find long-tail Google keywords in your niche by scraping the Google auto-complete feature. That gives you an initial list of search terms. The user is then allowed to filter irrelevant terms to produce a smaller list.
Step 2 is to use the Google Keyword research tool to evaluate the competition, number of searches and approximate CPC (am I missing anything here?) for the keywords found in step 1. The results of step 2 are then presented to the user to filter the list of search terms for step 3.
Step 3 is to scrape the Amazon auto-complete for whatever categories are applicable using the filtered keywords in step 2. For each keyword in step 2 we will then collect anywhere from zero to ten Amazon search terms. The user can then filter these terms to eliminate irrelevant ones.
Step 4 is to go to Amazon and enter each one of the search terms (both Google and Amazon) in step 3 and collect the item information for the first X results.
The end product is an excel (.csv) file with the keywords and product information and optionally it will create the affiliate links that you can then copy and paste in your site.
The product is going to be free (I will monetize via content locking) and will work only in Windows machines. The idea is that the user needs to opt-in during the registration process (it builds my list) and the program will also present ads for other products, offers, etc. from my site in the splash screen.
