About Zodiac Compatibility Online

Zodiac Compatibility Online is an independent astrology education site focused on relationship insight. We publish a free calculator, all 78 sun-sign pair reports, sign hubs, and guides on elements and synastry so you can explore a match without creating an account.

Editorial approach

Our reports combine classical factors (element harmony, modality dynamics, opposite-sign polarity, planetary rulership) with practical relationship language: needs, conflict patterns, friendship dynamics, and repair tips. Scores are deterministic for a given pair so the same match always returns the same numbers.

What we offer

• A free compatibility calculator for all 12 signs.
• In-depth reports for all 78 zodiac pairings.
• Individual sign guides (for example Aries and Pisces) with ranked matches.
• Tools for love, synastry and the Chinese zodiac.

Standards we follow

We aim for people-first pages: clear structure, visible FAQs that match the page, and no paywalled teaser scores. Sun-sign astrology is entertainment and self-reflection. It is not medical, legal, or clinical advice, and it cannot replace communication between real partners.
