What Each Tool Optimises For
Trustmary optimises for displaying social proof and measuring satisfaction: video testimonials, NPS/CSAT surveys, and a deep widget library to put proof on your pages. It imports your existing Google and Facebook reviews to show them off.
HearBack optimises for growing the reviews in the first place — continuously adding fresh 5-star Google reviews and replying to them — so the number on your Google profile climbs. It includes widgets for display, but the engine is collection and routing. If you need more reviews, HearBack; if you need to showcase the ones you have (plus video and surveys), Trustmary.
