What is the biggest challenge when searching for an insurance advisor in Germany?

We built Versipedia because finding a local insurance advisor in Germany often feels fragmented. Some people search on Google, some rely on insurer websites, and others ask for recommendations.

Our goal is to make this process more structured: search by city, ZIP code and insurance category, compare profiles, and contact advisors directly.

I would be curious to hear from others: what matters most when choosing an insurance advisor — location, specialization, reviews, personal profile, or something else?
