## The panel's verdict

No written verdict: the summary did not survive our own contradiction check, twice. The scores and sources below are unaffected.

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price.

### The judges

- **The In-House SEO Lead** (v1.0): Owns organic traffic for one large German site and reports on it monthly. Wants German-language keyword data that is not an afterthought, rankings she can defend when they disagree with Search Console, and audit findings specific enough to become a developer ticket.
- **The Agency Owner** (v1.0): Runs forty client sites and rebills the licence. Wants multi-client management, white-label reports a client can receive unedited, and per-seat costs that do not punish a growing team. Reads "contact us" on a pricing page as a margin problem.
- **The Technical SEO** (v1.0): Lives in crawl data and log files. Wants JavaScript rendering, crawl budget analysed, indexation diagnosed rather than listed, and regressions caught between crawls. Treats an issue list sorted by count rather than by traffic impact as busywork.
- **The Content Strategist** (v1.0): Decides what gets written and can only commission so much. Wants topic clusters, honest opportunity sizing, cannibalisation caught before it happens, and briefs scored against what actually ranks rather than against keyword density.
- **The Data Analyst** (v1.0): Wants the numbers in the warehouse, not in a PDF. Cares about a documented API with published credit costs, bulk historical export, and whether three years of ranking history leaves with the customer or dies with the subscription.
- **The Skeptic** (v1.0): Knows every vendor claims the largest index and the most accurate rankings, and that no buyer can check either. Reads instead for what can be held to: refresh frequency, stated limits, credit costs per endpoint, and what the invoice does when the team adds a seat.
