For a couple of months now, I've been highlighting new features in Repeat Customer Insights with a tiny badge. Here's one feature that I just released yesterday:
It's a simple bit of a code but it can draw attention to things that would otherwise be missed.
They work especially well on products. "New product", "New colors", "Longer battery life", etc.
A designer could easily create a similar one for your store and there are plenty of apps and theme options to add them. Tom, a good friend of mine runs one called Flair.
Badges also work well outside of product attributes. You can use them to call-out important resources or shipping deadlines or upsell offers or even silly puns.
All they take is a bit of color, bit of text, and a touch of design.
Track down which customer cohorts perform the best
Different groups of people behave differently. Repeat Customer Insights creates cohort groups for you automatically to see how your customers change over time and spot new behavior trends.
