Frequently asked questions
Transparency Certification evaluates a tree service’s review profile for signs of manipulation, including coordinated review activity, incentivized reviews, and AI-generated content at scale. Every certified tree service on this page has passed that audit and committed to FTC-compliant review practices. Look for the Transparency Certified badge to confirm a business’s status.
No. The Transparency certification audits review authenticity — not service quality. Every business here has passed the same independent audit. Results are sorted by certification date, not by quality ranking.
Yes. Certification is re-evaluated regularly. If our system detects a pattern consistent with review manipulation — such as coordinated activity, velocity anomalies, or other signals — the business’s certification is removed and the owner is notified. Businesses can request remediation and reapply.
Submit your business for certification review. Our team will run an authenticity audit of your review profile and contact you with results. If you pass, you’ll commit to responsible review practices and be listed in the directory.
