You're running into one of astrology's biggest issues: there's literally no quality control or consistency between providers. The zodiac system itself is pretty basic - your sign depends on your birth date, that's it - but everything built on top of that is subjective and varies wildly. One astrologer might focus on your sun sign, another on your moon sign, a third on planetary positions that day. Some use tropical zodiac, some use sidereal. There's no "official" rulebook, so each site is basically making its own rules.
I got curious about this a few years back because my partner was deep into checking horoscopes and we noticed the exact same thing you're describing. We checked the same three sites for a whole week and barely found overlap. One was consistently pessimistic, one weirdly positive about everything, one was so generic it could apply to literally anyone. Turns out some of these sites don't even employ actual astrologers - they're just templates or algorithms spitting out combinations of vague statements. The ones that do hire people? Those astrologers still disagree on methodology, so you end up with totally different interpretations.
So if you're trying to use horoscopes as actual guidance, you're fighting a losing battle because there's no standardization. It's more like comparing product reviews from different sources where each reviewer has their own criteria. Fun to check out, but don't make decisions based on them since the next site might tell you something completely opposite.
