No, there is no need to connect your Seller Central account (or Amazon account) in order to use the Extension or other product and keyword research tools.
If you are being asked to connect your Seller Central account to use the Extension, then this may be happening due to the page on which the Extension is being run.
You see, in order for the Jungle Scout Chrome Extension to pull data and product information, the Extension has to be opened on a specific product page, a search page, or a seller storefront page.
It won't work if you're on the amazon.com home page, since you need to be looking at a unique item.
Another reason could be the fact that you are running the Extension on the marketplace that is not supported. Please note that the Extension only supports the following marketplaces:
- Amazon US (amazon.com)
- Amazon Canada (amazon.ca)
- Amazon Mexico (amazon.com.mx)
- Amazon UK (amazon.co.uk)
- Amazon France (amazon.fr)
- Amazon Germany (amazon.de)
- Amazon Spain (amazon.es)
- Amazon Italy (amazon.it)
- Amazon India store (amazon.in)
- Amazon Japan store (amazon.jp)
