Taking an online test is a good starting point for further exploration of your possible types. The more reliable free and paid online Enneagram Tests are provided by the major players in the field. These tests can be useful in giving you information about your type.
However, no personality assessment instrument can ever achieve 100% validity and reliability, so be aware that these tests may not give you an accurate result. You can try them out and see which one gives you a more accurate result. Personally, I prefer Eclectic Energies’ Free Online Test because it’s quite comprehensive and it’s free.
