Take it or not, and why
Every agency profile opens with the verdict, the strongest proof and who said it, the price against the ranking median, and what to ask before you sign. Everything else sits one click below, with its source.
- The verdict comes from the best rank and how much of the proof is independent.
- Each proof item says who is speaking: an independent source, the agency itself, or a Vendar profile field.
- Every number links to the facts behind it.
After 1 year of using Sitechecker, Wiideman Consulting Group reported a 33% improvement in average Google SERP position (from 20 to 15) and a 10% improvement in click-through rates over the last 6 months vs the 6 months prior, based on their SEO auditing and monitoring work with the tool.
Independent sourceWho wrote it matters more than where it sits
A client review, a press article, a rating by a third party.
Case studies, service pages, pricing on its own site.
A field the agency filled in its Vendar profile, checked by Vendar only when marked verified.
- Only an independent source counts as outside proof; what an agency says about itself is labelled as such.
- No rank means nothing on file shows the work yet, not that the work is poor.
The same data for people and AI
Every profile and ranking has a machine-readable twin with the same numbers. Ask ChatGPT, Claude or Perplexity to check our verdict from any profile.
profile_status: revieweddecision_ready means the page and the feed agree; needs_review flags a blocking disagreement in the feed itself.
A place is earned with documented work
Add a case study, a project or a client review we can link to, and the next pass weighs it. Paid visibility exists, is always labelled, and never changes the order.
