While it's best to think of all these factors, just by looking at the sun sign, which is what you're most familiar with when describing yourself as an Aquarius or a Leo, can give some insight as to whether you'll get along. Taking moon into consideration can lead to some contradictions in compatibility, as you may connect well with someone on that deeper level.
The sun sign is your basic personality, your ego, and how you center yourself, whereas the moon sign describes your inner emotional life, your deep needs, and your hidden side that you don't easily show most people, he explained.
"This question is like nails on a chalkboard for most astrologers because there's so much more to consider than just the sun sign," he said. "In general, though, Fire and Air signs (Aries, Leo, and Sagittarius; and Libra, Aquarius, and Gemini) go well together, while Water and Earth signs (Cancer, Scorpio, and Pisces; and Capricorn, Taurus, and Virgo) get along well."
The other combinations are less compatible generally, but this idea is constantly contradicted. The whole chart has to be taken into consideration for astrology to really be an effective matchmaker. "An Aries with a Taurus moon, for instance, may get along famously with a Virgo, though their sun signs are not considered particularly compatible," he explained.
Still, here's how using astrology can help you find your match.
