Methodology
Everything here is either verified public data or clearly-framed buyer education. We do not fabricate credentials, statistics, case counts, ratings, or reviews.
Vendor reference data
The 28 vendors in the reference layer are real, publicly-documented expert networks and independent-consultant marketplaces. Each record was researched and then independently re-verified via web search before publication, with source URLs recorded. Where a vendor's ownership recently changed (an acquisition, a rebrand, a merger), we say so in the profile rather than presenting a stale independent identity. We do not invent or list unverifiable local firms.
Search demand
Guide priority and the demand figures shown on guide pages come from Ahrefs keyword data for the United States. Where we did not pull a reliable figure for a term, we show no number rather than guess one.
Sourcing guides
Each guide is buyer education: what the category covers, what to verify, what to ask before you engage, and the red flags. Every guide passed an adversarial fact-check pass whose job was to remove any invented statistic, unverifiable claim, or implication of a guarantee. Verify any compliance or credential claim directly with the vendor.
What we will not do
- No fabricated credentials, network-size figures, case counts, or vendor counts. Where a vendor doesn't publicly disclose a number, the profile says so rather than estimating one.
- No fake reviews, ratings, testimonials, or fabricated "verified" claims. A paid Verified listing (see Get listed) means KG manually confirmed the business's identity and the accuracy of its own listing facts, nothing more. It is not a customer review, a star rating, a quality score, or an endorsement of the vendor's work.
- No Review or AggregateRating structured data, because no real moderated customer reviews exist here.
- No claim that any vendor is suitable for your engagement, or that any vendor meets a specific compliance standard, unless a real cited source says so. That verification is your call, made directly with the vendor.
