Astrology Compatibility: How It Works
An introduction to compatibility beyond Sun signs, including chart context, aspects and synastry.
The short version
Compatibility astrology can provide a framework for reflection, but no chart comparison can guarantee relationship quality or outcome.
What this guide covers
This page is designed as a focused destination for the question in its title. It explains the relevant concepts, shows how they connect to the wider relationship-astrology ecosystem, and points to a commercial next step only when that next step matches the reader’s intent.
How to evaluate the idea
Separate three things: the tradition being used, the experience being sold, and any claim about real-world prediction. Astrology and soulmate-themed services can be meaningful or entertaining to users without their predictive claims being scientifically demonstrated.
