Titan

Titan is built for Amazon sellers and product researchers who would rather gather data where they already work. Rather than copying BSR numbers into a third-party tool, you open Amazon, run a keyword search, and trigger the Atlas feature. Titan then pulls together estimated revenue, sales velocity, review momentum and competitor keyword data for the products and niches on that page.

Its most distinctive capability is reverse ASIN analysis. By working backwards from competitors' listings, Titan reveals which search terms are driving their traffic, which lets you sort a crowded niche into the handful of competitors you can realistically out-rank. That insight feeds directly into keyword prioritisation, so your listing copy and PPC spend target the same terms from day one.

The extension is aimed at sellers in the idea-validation and launch-planning stages, as well as established sellers expanding into adjacent categories. It is deliberately lightweight, published by Titan Tools LLC in Clearwater, Florida, and updated regularly through the Chrome Web Store.
