Methodology

How Lumar GEO Studio measures generative search

The retrieval pipeline behind the product — and which stages Lumar GEO Studio observes today.

Start with the pipeline, not the rank

Generative engines do not return a ranked list. They select candidate pages, retrieve passages, synthesise an answer, and cite evidence. Optimisation fails when you improve the wrong stage. Lumar GEO Studio is built to mirror that pipeline in software.

StageWhat happensIn Lumar GEO Studio
1. AvailabilityPage can be fetched and parsedCited-page crawls; content eval requires a reachable URL
2. Candidate selectionPage is allowed to compete for this queryPrompt runs + cited-page lists — if absent, the failure may be upstream of content quality
3. Chunk retrievalPassages are embedded and matchedContent Precision, Semantic Recall, chunk-level eval
4. Synthesis & citationContent is quoted and linked in the answerAnswer logs, citation quality, brand mention quality, visibility score
5. Brand positioningBrand is named vs competitorsBrand mentions, mention quality (role, placement, prominence)

Two measurement layers in the product

Prompt-level (AI Visibility) — tracks how AI models answer the queries you care about.

  • Scheduled prompt runs per project and AI platform
  • Visibility score — composite of how often and how well you appear (citations + brand mentions)
  • Cited pages — URLs the model linked to when answering
  • Brand mentions — named references to your brand and competitors in the answer text; competitor tracking is built in

Page-level (content evaluation) — assesses whether a specific URL is structurally fit to be retrieved and cited.

  • Evergreen Health: headline composite (0–10) across Content Precision, Semantic Recall, Content Freshness, Content Uniqueness, and Questions Answered
  • Content Precision and Semantic Recall: the two core content-quality signals
  • Runs on cited pages (and pages you send to the copywriting workspace)

These layers connect: a prompt run tells you that you lost a query; page evaluation tells you why a URL may not be citable.

What visibility score actually reflects

Visibility score is not a rank position. It combines:

  • Citation quality — when your owned URLs are linked, how strong those citations are
  • Brand mention quality — when your brand is named, how well that mention serves you (role, placement, prominence, sentiment)

Both components are dampened by consistency — appearing in 1 of 10 runs with a perfect quality score ranks lower than appearing reliably with good quality. A one-off spike is weaker signal than sustained presence across runs. Mentions carry more weight than citations in the composite (roughly 3:1), so brand positioning in the answer text matters even when your URLs are not linked.

Use visibility at topic and prompt level for prioritisation. Use per-model breakdowns when platforms diverge — different AI providers often behave differently for the same prompt set, especially across informational vs comparison queries.

What the product does not claim to measure

Be explicit about limits:

  • No guaranteed view into proprietary retrieval indexes — you observe outputs (answers, citations, mentions), not internal candidate pools
  • Prompt sets are samples — conclusions strengthen with cadence and trend length, not single runs
  • Content scores evaluate page fitness — they do not replace live prompt monitoring after you publish
