Judge.me's free plan already covers unlimited reviews, photo and video reviews, widgets, Google sync and the importer. So when a store pays an expert, it's for one of a handful of specific jobs, and most come down to fit and data.
Widget placement and styling. On Online Store 2.0 themes, the expert enables the Judge.me app embed, adds the Review Widget block in the theme editor and styles the widgets, star ratings and testimonial sliders to match the product page. Vintage themes need the widget added in Liquid by hand.
Imports. Bringing reviews over from a previous review app or a marketplace, then checking that photos and product matches landed where they should.
Review requests. Getting the timing of request emails right and, on the Awesome plan, attaching coupons and referrals so a review leads to a repeat sale.
Syndication. Sending reviews to Google, the Shop app and social channels so ratings appear beyond your own product pages.
Shopify Flow. Using Judge.me's triggers ("New review received", "Review request ready") and actions ("Send review requests for order", "Skip review requests for order"), for example to skip requests on wholesale orders.
Headless and custom builds. Reading and creating reviews through the Judge.me API, and rendering widgets on a headless storefront from the Widget API.
What rarely needs paying for is ongoing management. Once Judge.me is configured properly, it mostly runs itself.
