Crestfull (often referred to as Crest) is an Etsy-focused SEO tool designed to help sellers improve shop performance using keyword insights, shop analytics, listing optimization, and tracking—all with a user-coaching approach.

It offers keyword and trend analysis tools, real-time monitoring of SEO performance, competitor evaluation, and intelligent alerts for seasonal changes or product popularity shifts.

Crest positions itself as a personal coach for your Etsy shop. Rather than simply gathering data, it analyzes metrics such as sales patterns, customer demographics, and listing quality—and offers suggestions to improve rankings, titles, tags, and visibility.
