## Identity

- platform_url: https://twitter.com/sengineland
- website: https://www.searchengineland.com
- entity_type: creator

## Reach
- followers: 453418
- following: 665
- posts_total: 88835
- posts_observed: 7
- posts_per_day: 12.4
- account_age_days: 7164
- verified: true
- size_tier: kol

## Engagement
- status: peak_post_only
- peak_post_engagement_rate: 0
- best_post_interactions: 2
- measurement_source: x_post_interactions
- measurement_formula: interactions on one post — likes, or likes + reposts + replies depending on the discovery path (the two are not distinguishable in the stored data)
- comparable_pool: peak_interactions
- status_note: We have only the single best observed post, so no mean exists. peak_post_engagement_rate is an UPPER BOUND, systematically higher than an average — never compare it against an average rate.
- unit_note: engagement_rate and peak_post_engagement_rate are ratios (0-1); avg_interactions_per_post and best_post_interactions are absolute counts. Read status before reading any number: a null rate has several different causes and status says which one applies here.

## Evidence
- [x_sengineland#7a220e2b] Stop clustering #keywords by hand. This Python workflow uses TF-IDF + HDBSCAN to group thousands of queries into topics, isolate outliers and export the results to Excel. Here's the step-by-step: https://t.co/H8jRCuuJqM https://t.co/dQvo9KJh7f (https://twitter.com/sengineland/status/1582399358468702208)
- [x_sengineland#b9739750] Your #YouTube channel may already rank in Google Search and GSC can now show you where. One channel logged 203,000 impressions in 11 days. Here's how to build the map: https://t.co/0ktJPgvCDP https://t.co/29awlDBuyN
- [x_sengineland#9f7603e0] 44% of #LLM citations come from the first 30% of your content. AI Overviews favor proprietary data. Generic "what is" pages are losing ground fast. Is original research or proprietary data now a core part of your content strategy?
- [x_sengineland#c8e8c10b] Google Search appears to be testing a new human-verification step: Sign in to your Google account to see more results instead of completing a CAPTCHA. It looks limited for now 👀 Learn more here: https

Every inferred field below carries how it was produced. Facts stay facts; inferences stay inferences.

- audience.description: source_type=ai_inferred, confidence=0.4, freshness_days=76, method=llm_persona_from_recent_content
- audience.roles: source_type=ai_inferred, confidence=0.4, freshness_days=76, method=llm_persona_from_recent_content
- audience.seniority: source_type=ai_inferred, confidence=0.4, freshness_days=76, method=llm_persona_from_recent_content
- commercial.audience_buyer_fit: source_type=ai_inferred, confidence=0.6, freshness_days=77, method=llm_scorer — Relative signal within Koinon indexing, not a market-wide score.
- commercial.promotion_intent: source_type=ai_inferred, confidence=0.6, freshness_days=77, method=llm_scorer
- quality.anomaly_flags: source_type=heuristic, confidence=0.5, freshness_days=108, method=profile_snapshot_and_engagement_ratio_heuristic — Means "worth a manual check", NOT confirmed fraud. Flags can be wrong and are not a verdict about the person.
- quality.authenticity_score: source_type=heuristic, confidence=0.5, freshness_days=77, method=Profile-shape heuristic from a single snapshot (follower count, following ratio, account age, posting volume, verification), reduced for engagement red flags where post engagement was collected. Where only a follower count is available the score saturates at 58. — The input set differs by platform; do not compare this score across platforms.
- quality.koinon_bd_grade: source_type=ai_inferred, confidence=0.5, freshness_days=108, method=llm_partner_fit_classifier + fit_score >= 0.6 AND authenticity >= 60 => A; fit_score >= 0.4 AND authenticity >= 45 => B; else C. authenticity < 30 or a promotional-pattern flag => quarantine. — Koinon partner-outreach fit, not creator quality.
