::FACT{key:ads|value:"Preserve close variants, geographic and language targeting, network and period. competition_index is ad placement competition, not organic ranking difficulty. Preserve ranges and missing values"|source:https://developers.google.com/google-ads/api/docs/keyword-planning/generate-historical-metrics}

::FACT{key:rpm|value:"Page RPM = earnings / pageviews * 1000; never equate pageviews, clicks, impressions and searches"|source:https://support.google.com/adsense/answer/112030}

::FACT{key:parameters|value:"Windows, percentiles, RRF c, BM25 k1 and b, MMR lambda, candidate caps and decision rules are design choices. Compute values from data; validate choices on held-out outcomes"|conf:method}

::RULE{S0_INTAKE=>obtain seed, market, language, business model, site if any, desired output size and authorized spend cap; no permission inferred from this document; a configuration example such as USD 5 is not approval to spend}
::RULE{S1_ACCESS=>inspect available Google Ads or Planner export, Trends API or user CSV, GSC OAuth and authorized DataForSEO access; ask only for missing access relevant to the run; secrets stay out of chat; missing source stays missing; never synthesize observations}
::RULE{S2_BUDGET=>read current provider prices; estimate calls, retries and cost; obtain run-specific authorization before paid requests; log actual cost; stop before exceeding cap; never recharge automatically}
::RULE{S3_CONFIG=>record country, language, location, device, search type, collection dates and windows; distinguish data-derived values from chosen parameters; suggested starting configuration is 200 candidates, top10 organic results, RRF c=60, BM25 k1=1.2 b=0.75; all are configurable, not universal constants}
::RULE{S4_DISCOVER=>collect related queries and topics through permitted Trends access and suggestions or PAA through authorized SERP provider; preserve source and date; tag brand, navigational, news, sports and transactional intent; exclude only when outside the owner's declared scope; deduplicate exact variants without merging different intents}
::RULE{S5_TREND=>use comparable series from the same scaling context; report recent versus baseline medians, slope and persistence with explicit windows; zero or tiny baseline gives undefined or unstable relative growth, not infinite opportunity; compare seasonally aligned periods when available; do not force a cycle from an insignificant autocorrelation peak}
::RULE{S6_BURST=>run Kleinberg's binomial batch model only with real counts r_t and total counts d_t with 0<=r_t<=d_t; p0=sum(r_t)/sum(d_t), p_i=p0*s^i with valid p_i<=1; emission cost=-log[binomial(d_t,r_t)*p_i^r_t*(1-p_i)^(d_t-r_t)]; upward cost=max(0,j-i)*gamma*log(n); s and gamma require declared choices; Trends indices alone=>skip binomial model and label trend evidence pending validation}
::RULE{S7_VOLUME=>request historical metrics with consistent market, period and network; preserve average and monthly searches, ranges, bids, close variants and missingness; do not add duplicate close-variant groups; advertiser competition is a separate field; growth and trend evidence remain distinct and correlated inputs are flagged}
::RULE{S8_NEW_TERMS=>missing Ads volume does not mean zero demand; optional estimate Vhat(k,m)=V(anchor,m)*T(k,m)/T(anchor,m) only with positive stable anchor and aligned period, location, search type and query definitions; use multiple comparable anchors and repeat samples; report range and assumptions; mismatched definitions, unstable ratio or low-volume suppression=>leave volume unknown}

::RULE{S9_ECONOMICS=>define V=monthly searches, alpha=empirical impressions/search coefficient, q=conditional CTR, p=pageviews/click, rho=page RPM, C=monthly allocated page or topic cost; clicks=V*alpha*q; pageviews=clicks*p; revenue=pageviews*rho/1000; Vmin=1000*C/(alpha*q*p*rho); if coefficient beta already predicts clicks/search use clicks=V*beta and do not multiply CTR again; no calibration=>report scenarios, no hard profitability rejection}
::RULE{S10_SERP=>collect fixed-depth organic results and result-type labels, retaining social and video organic entries; record incomplete results; define w_i=1/log2(i+1); a_i=percentile of the domain's occurrence frequency in this candidate batch, not authority; C_serp=sum(a_i*w_i)/sum(w_i), a descriptive competition proxy; preserve original positions; compare only matching scope}
::RULE{S11_CONCENTRATION=>aggregate position weights by domain, p_d=sum(domain weights)/sum(all weights); HHI=10000*sum(p_d^2); use as a descriptive feature; antitrust cutoffs such as 1800 are not validated SEO thresholds and never alone decide rejection}
::RULE{S12_DOMAIN_AGE=>read RDAP registration dates where available; missing dates remain unknown; registration age is not site launch age; deduplicate domains before calculating age distribution; P10 may flag relatively young domains as a chosen screening rule, not proof of a new site or an open SERP; inspect page intent, quality and migration clues}
::RULE{S13_IDF_GAP=>fix tokenizer, language and corpus; IDF(t)=log((N+1)/(df(t)+1)); mean token IDF is a corpus-specific rarity proxy, not value; use BM25 only as lexical matching evidence under fixed fields and corpus; low title/snippet match creates a gap hypothesis; inspect pages and record unmet intent before treating it as a verified opportunity; cross-query raw BM25 scores are not inherently comparable}
::RULE{S14_CUTS=>report chosen percentile levels, exact computed values, sample units, n, date and uncertainty; P10 age, P75 competition or top-decile growth are configurable screening policies, not natural constants; small or tied samples, empty reference sets and unstable estimates=>no hard cutoff; calibrate against prior outcomes with time-based validation}
::RULE{S15_REVERSE=>from evidence-backed candidate SERPs inspect permitted competitor sitemaps and page titles; extract phrases as hypotheses; validate through the same metrics pipeline; stop at authorized cost cap, output cap or a predeclared marginal-novelty rule; no infinite recursion or assumption that a young domain is successful}
::RULE{S16_FUSE=>consider up to seven lists: trend persistence, measured volume, growth, low C_serp, verified gap, commercial-value proxy and specificity; retain the exact same usable dimensions for all candidates in each comparison set; no fabricated missing ranks; evidence-incomplete candidates get a separate pending list; rank from1, RRF(k)=sum_j[1/(c+rank_j(k))], starting c=60; equal lists are equal votes, dimensions and c are choices; check correlated votes and sensitivity}

::RULE{S17_DEDUP=>fix embedding model and similarity range; choose next k maximizing lambda*Rel(k)-(1-lambda)*max(sim(k,s) for s in selected); empty selected=>redundancy0; Rel=RRF percentile within its comparison set; declare lambda and validate on held-out judgments or outcomes; 1-max(cosine) is a semantic novelty proxy, not information-theoretic gain or a proven Google ranking factor; cluster by page intent, not wording alone}
::RULE{S18_DECIDE=>first label missing or conflicting decisive evidence as 待验证; then apply explicit business-scope and authorized-budget constraints; among comparable evidence-complete candidates rank by declared policy; 优先 means selected for the next validated test, 可做 means qualified reserve, 放弃 requires a recorded disqualifying reason; never force all candidates into three tiers using the largest score gaps; no predicted ranking success guarantee}
::RULE{S19_REPORT=>deliver matrix x=search volume or aligned estimate, y=C_serp, unknown-volume candidates separately; show any screening line as provisional; table includes query and variant group, intent, demand source/range, trend, SERP scope, HHI, gap evidence, RRF comparison set, novelty, decision, n, dates, assumptions and costs; mark all synthetic examples as teaching examples}
::RULE{S20_FEEDBACK=>after indexing compare matched page/query cohorts at a declared interval; refit impression and CTR models without multiplying CTR twice; keep failed and unselected evidence where observable; split evaluation by time and topic to reduce leakage; separate organic exposure effects from outcome quality; NDCG needs explicit relevance gains and an ideal ordering; clicks are observational outcomes, not proof of causal effectiveness; save versioned calibration data}

::FALLBACK{no_ads=>user Planner export or volume unknown|no_trends=>user CSV or trend unmeasured|no_gsc=>scenario economics, no calibrated floor|no_serp_provider=>SERP unmeasured, decisions pending|third_party_estimate=>label model and uncertainty, never relabel official|small_sample=>rank cautiously and report uncertainty|over_budget=>stop or propose fewer candidates without new charges|tool_error=>report affected scope, no invented substitute}
::RUBRIC{evidence:"sources and dates attached"|units:"searches, impressions, clicks, pageviews and revenue separated"|methods:"valid inputs and proxy limitations"|parameters:"choices declared and sensitivity checked"|uncertainty:"missing data kept visible"|budget:"authorization and cap respected"|output:"reproducible decisions and calibration record"}
