Rated from the evidence on file (sources, independence, confirmed quotes), not by an editor.
Best position confidence
Moderate confidence

It starts from the data completeness and source reliability of the profile, and is capped when independent proof of work is thin. The next level is Moderate confidence. One independent claim with a measured result for the best-ranked need is the fastest way up.

Data completeness68/100
  • Who the company is: website, headquarters, founding year, team size, logo, regions served: founding year, team size, logo10/20
  • Fit: services, industries, client types15/15
  • Commercial terms: model, entry price, hourly rate, minimum term, setup fee: hourly rate, setup fee13/20
  • Documented work: cases naming a client and a result (target 5) and work claims overall (target 10): 6 cases with a named client and a result, 12 work claims30/30
  • Reputation: rating and review count on two or more platforms, each with 10 or more reviews: 0 platforms with a rating and 10 or more reviews0/15
Trust in the data70/100
  • Who is speaking: independent sources among work claims (full marks at 40%): 0 of 12 work claims are independent0/30
  • Checked against the source page: confirmed, or half for partly confirmed: 12 confirmed, 0 partly, of 12 with a source25/25
  • Numbers backed by a verbatim quote from the source: 8 of 820/20

  • Not contradicted: claims their source no longer supports: 0 not supported by their page10/10

These two scores describe the profile itself and never change a position.

Limits and how to correct them
  • No independent source names SEO for startups work; the evidence is first-party or editorial.
  • Never verified against official sources.
  • No independent source on file: Every claim on file is first-party or a Vendar profile field.
  • Profile below decision-ready status: the profile is collected but not reviewed yet.
  • Use as a caveated candidate only: no independent source documents this vendor's work.
  • None of the 12 documented work claims comes from an independent source; all are the agency's own account or sources it controls.
  • No third-party evidence claims are normalized.
  • Best position rests on: Published by the agency on its own site.
  • 12 of 12 claims on file are the agency's own words or sources it controls; 0 come from an independent source.
  • Open: Three strongest proofs name a client and a measured, dated result (0 of 3)
  • Open: At least a third of documented work comes from independent sources (0 of 12 work claims)
  • Open: Founding year, team size and headquarters on file (founding year missing, team size missing)
