How TrustRank Ranks Listings
CarArth scores every listing on four data quality dimensions. No seller can buy their way to the top.
Why Ranking by Trust Matters
Many online marketplaces prioritize listing visibility based on promotional placement or advertising spend. While these systems generate revenue, they make it difficult for buyers to distinguish between genuinely informative listings and heavily promoted ones.
TrustRank flips this model: listings are ranked by the clarity and completeness of the information they provide — not by who paid more.
What TrustRank Measures
Four dimensions evaluated algorithmically for every listing.
Information Completeness
Detailed specs, variant info, complete description
Missing or vague vehicle details
Documentation Signals
Service history or clear ownership indicators
Unclear or absent documentation
Pricing Context
Price consistent with comparable market listings
Large unexplained deviations from market price
Listing Transparency
Clear descriptions, consistent photos, accurate data
Contradictory or incomplete listing elements
What TrustRank Does Not Measure
TrustRank is designed to remain completely independent of commercial signals.
