Ranking methodology
The order reflects real, verifiable signals that are hard to manipulate. Companies with a verified state license appear first; within that group we prioritize the best-reviewed (verified reviews) and the most established according to official records. Profile views and community recommendations only fine-tune the order — a couple of votes can't move positions. For each company we show exactly which signals back its position.
- State license — we verify each active license against state licensing boards like California BSIS and Illinois IDFPR. Licensed companies appear first.
- Real profile views — how many people viewed the company's profile over the last 30 days.
- Community recommendations — user votes with anti-fraud controls (fingerprint dedup).
- Verified customer reviews — customer rating and review volume, when available.
