Keyword Trend Hunter

Keyword Registration Trend Hunter

What this does: discovers keyword spikes, checks whether each spike is supported by broad participation in the same new-registration event cohort, and optionally surfaces related dropped, expiring, or listed inventory. It evaluates open-market registration participation, not aftermarket demand or investment merit.

Data interfaces it needs. DomainKits MCP supplies part of the evidence through the tools below; it is not the complete analysis engine. Use equivalent sources when available and use host-provided web access for public-page checks. Never assume a field exists merely because the workflow needs it. Mark an unavailable field or capability Unavailable and continue.

• Keyword registration trends and source-computed aggregate metrics (hot, emerging, prefix), DomainKits: keywords_trends. Read registrar Top-1 / Top-3 only from this trend source when returned.
• Newly registered domain rows for naming-pattern and coarse timing detail, DomainKits: nrds. It does not provide registrar / provider, so never calculate registrar concentration from it.
• Registrable / expiring / listed inventory, DomainKits: deleted / expired / aged
• Availability confirmation, DomainKits: bulk_available
• Web access for a lightweight brand-dominance and collision check before candidate inventory is surfaced

Skill boundary: this skill owns trend discovery, event-cohort integrity, preliminary open-market validation, and optional lifecycle inventory. Use keyword-intel for the full evidence picture of a selected keyword, including search-audience, advertiser, installed supply, active offers, and completed transactions. Do not reproduce those layers here.

Open-market participation model

This skill evaluates trends within the global, general-purpose open domain market. Its core evidence is new-registration participation: .com participation is necessary confirmation of open-market interest, but it is never sufficient by itself. The full model requires broad, persistent, and structurally diverse participation rather than one concentrated registration pattern.

.com is the primary confirmation layer because it is the most established global namespace and aftermarket: registration cost and quality-name scarcity are higher, global recognition and end use are broader, secondary-market liquidity is stronger, and registering a .com means accepting more competition. It remains the largest single TLD by registration volume. A keyword trend with little or no .com participation is not considered validated by the open domain market, especially when registrations are concentrated in one low-cost TLD, one registrar, or a repeated naming pattern.

This model does not claim a non-.com ecosystem cannot be active. It means such activity has not been validated as a broad open-market domain trend. Country-specific ccTLD markets and extension-native ecosystems require a separate model.

Independent participation, not raw .com count. A large .com block created through one concentrated pattern is not broad participation. Read the cohort from seven signals together: absolute .com count, com_ratio, registrar concentration, naming-pattern diversity, persistence across windows, low-base status, and single-TLD concentration. Registrar concentration is a necessary participant-diversity proxy, not registrant identity or a direct participant count. Use the trend provider's aggregate registrar distribution; use nrds only for the domain-row signals it actually returns.

Event-cohort integrity

The trend record and the detailed nrds sample must describe the same event before their signals are combined.

• Record the detected keyword, provider-defined match semantics, provider-supplied window or bucket definition, data date when supplied, query observation time, TLD or feed coverage, and event-cohort total from keywords_trends. Do not manufacture exact event start or end dates from the query date. If the source exposes only a nominal rolling window, report that window and mark exact boundaries Unavailable.
• Pull nrds for the same keyword and constrain it to the same dates and TLD or feed coverage where the interface permits. If exact alignment is impossible, label nrds as supplemental and do not merge its ratios or concentration metrics into the provider's event-cohort figures.
• For domains reviewed from nrds or inventory, include the keyword only when it is an exact label, a hyphen-delimited component, or an unambiguous component in a concatenated label. Exclude accidental substrings and ambiguous segmentations from the primary sample; variants belong in a separately labeled secondary sample.
• Before calculating any ratio from nrds, deduplicate the sample and record returned count, pagination completed, result cap, and whether the source claims completeness. When coverage is incomplete or unknown, label ratios as observed-sample ratios. If the missing data could materially change .com participation, concentration, or persistence, the outcome is uncertain.

Signal thresholds (heuristic bands)

The following bands are heuristic starting points, not statistical laws. Treat a value near a band edge as uncertain, not decisive, and always show the underlying figure.

Data semantics: all ratios and concentration metrics are calculated from registrations contributing to the detected keyword spike, not from the total installed domain base. They therefore describe revealed choices within the incremental event cohort.

• com_ratio: core-market participation. Roughly, higher (around 0.15 and up) is consistent with genuine open-market interest; very low (around 0.05 and below) is consistent with bulk activity on cheap TLDs.
• most_tld_ratio: single-suffix concentration. High (around 0.7 and up) on a non-.com TLD is consistent with concentration in one suffix rather than broad demand.
• digit_ratio: naming-structure signal. High (around 0.2 and up) is consistent with template or bulk-driven registration.
• Registration persistence: measure as the number of distinct time windows (for example days within the cohort period) that carry new registrations, and the share of the cohort falling in its single busiest window. Persistent is roughly activity in several windows with no single window dominating (busiest-window share well under half); a single-day burst (one window holding most of the cohort) is not persistent. Show the per-window counts.
• Registrar / provider concentration and pattern concentration: use source-computed registrar shares from keywords_trends, reporting the single largest registrar's share and the Top-3 cumulative share when each is returned, stated with the provider cohort size. Do not reconstruct Top-3 from nrds or from an incomplete registrar list. Measure pattern concentration from the aligned domain-row sample as the share following one repeated template. A largest-registrar share around half and up weakens the evidence of broad participation but does not establish how many actors exist. A dominant template is direct evidence of structural concentration. Interpret registrar concentration together with pattern, suffix, and time concentration; never convert it into a registrant count.
• Low base: flag whenever the cohort total is small enough that ratios are unstable (for example a cohort in the low tens or fewer, or any single suffix or window driven by only a handful of names). A low-base flag caps the outcome at uncertain regardless of how the ratios read.

If these bands have been back-tested on historical data, state it and record: the calibration sample's date range; which TLDs the sample covers; the label used for a "validated" trend; and whether the bands are updated periodically. If they have not been back-tested, keep them as heuristic bands: the model supports the direction of each signal, but the specific numbers are not derived laws. Do not present a specific cutoff as a proven threshold without that calibration record.

Evidence discipline

• Use a fixed outcome order. Classify each selected trend in this order:
  1. Brand-specific / model not applied when the keyword mainly identifies one existing brand; do not surface candidate inventory.
  2. Uncertain when the cohort has a low base, cannot be aligned, has materially incomplete coverage, or is missing a signal that could change the result.
  3. Not validated by the open market when an adequately covered cohort has no .com participation or falls in the very-low .com band.
  4. Concentrated when .com participates but suffix, template, time, or combined registrar-plus-structure evidence shows the spike is materially concentrated.
  5. Open-market validated only when .com participation is meaningful, the cohort is not low-base, activity persists across windows, naming patterns are diverse, and no material concentration signal contradicts the reading. Mixed evidence that fits none of these rules is Uncertain. Always show the underlying figures. These are open-market registration outcomes, not investment instructions.
• Read participation from multiple signals, per the model above; never from .com count alone.
• Brand boundary. Run a lightweight public-web check on a selected keyword before validation is finalized or candidates are surfaced. If it mainly identifies one existing brand, report the observed spike only as brand-specific registration activity, stop the open-market model, and do not surface registrable, expiring, or listed names as opportunities. State that the check is not trademark clearance or legal advice.
• Do not infer a cause. Registration concentration, timing, or naming co-occurrence does not establish a promotion, sale, news event, or other catalyst. Use keyword-intel or domain-market-beat when the user asks for deeper market or event evidence.
• Lifecycle verification is stage-specific. bulk_available confirms only whether a name can be registered now, so it applies to deleted candidates. It does not validate expired (confirm backorder / auction status and provider) or aged (a current listing, not a sale). For an aged listing, attempt to re-check it against aged or the named marketplace before presenting it. If that re-check succeeds, record the verification source; if the marketplace cannot be reached, present the tool-reported listing labeled "listing not re-verified" and treat it as weaker evidence rather than dropping the candidate. Record status and observation time either way.

Workflow

Proceed end to end when the user names a keyword, requests a fixed number of trends, or explicitly asks for candidates. Pause after discovery only when the user must choose which surfaced keyword to validate. Pause before expired or aged only when willingness to backorder or purchase a registered name is unknown. Do not force phase-by-phase confirmation when the user's requested scope is already clear.

1. Discover. Surface trending keywords with keywords_trends (hot, emerging, or prefix). For each surfaced keyword, deliver a fixed set so runs stay comparable, marking any field the source does not provide as Unavailable rather than omitting it:

   • the provider-supplied cohort window or bucket definition, any provider data date, and the separate query observation timestamp. Never stamp or reconstruct event boundaries from the current date; if only a nominal rolling window is known, say so;
   • the coverage the source provides (which TLDs or feeds the cohort is drawn from, and whether it is a sample or claims completeness), so a difference between runs is not mistaken for a real change;
   • the spike / event-cohort total (how many new registrations define the trend);
   • the absolute .com count in that cohort when the source returns it, alongside com_ratio; never derive a supposedly exact count from a rounded ratio, and mark the count Unavailable otherwise;
   • the pre-computed structure metrics digit_ratio, most_tld, and most_tld_ratio (single-TLD concentration);
   • a preliminary participation reading from the provider's available metrics, using the heuristic bands and showing every underlying figure; never label it the final open-market outcome while registrar concentration, pattern diversity, or persistence remains Pending;
   • a low-base flag whenever the cohort total is small.
   • registrar Top-1 and Top-3 shares from keywords_trends when returned; mark either metric Unavailable when absent rather than attempting to recreate it from nrds; Pattern diversity and detailed time structure come from nrds in step 2, so mark those fields Pending here. Two cohorts are comparable only when their provider window, data date, coverage, and keyword-match semantics align. If the user has not chosen a keyword or requested an end-to-end top-N analysis, ask which keyword(s) to validate; otherwise continue.

2. Validate the event cohort. For each selected keyword:

   • Apply the brand boundary and event-cohort integrity rules.
   • Pull nrds for the aligned cohort and report its matching rule, returned count, pagination / result-cap status, naming-pattern diversity, hyphen / digit / length structure, repeated-template share, and the coarse time clustering supported by registered_date or the available recency buckets. Do not report registrar Top-1 or Top-3 from nrds. If it cannot be aligned to the trend record, keep it supplemental and make the outcome uncertain rather than merging unlike samples.
   • Apply the fixed outcome order to all seven signals. Report the outcome, confidence, exact figures, cohort dates, observation date, coverage, and unavailable fields.
   • If the user requests search-audience, advertiser, supply, offer, transaction, or catalyst evidence for the chosen keyword, use keyword-intel; do not rebuild those layers here.

3. Surface lifecycle candidates when requested. Skip this phase for a brand-specific keyword. Filter every result through the same keyword-matching rule used for the event cohort:

   • deleted for dropped names, each re-confirmed registrable with bulk_available.
   • expired only when the user accepts backorder (confirm lifecycle / provider).
   • aged with has_sale=true for current listings (a listing, not a sale). Present each candidate with: domain; exact keyword component and position; matching category (exact / hyphen-delimited / unambiguous concatenation); relation to the validated trend; lifecycle stage; acquisition path; verification source and result; price type, amount, currency, and date where applicable; observation date; and any brand-collision caveat. Exclude ambiguous matches. Mark unavailable fields explicitly. Present candidates as options, not recommendations.

Next steps

Only if the user asks: use keyword-intel for a full evidence analysis of a selected keyword, domain-analyze for one domain, monitoring for later changes, or repeat discovery for another trend set. Do not push acquisition or tell the user to act.

Key principles

• Judge trends against the global open domain market by aligned new-registration evidence; .com is necessary confirmation, not sufficient proof and not evidence of aftermarket transactions.
• Keep keywords_trends and nrds in one event cohort when their provider window, data date, coverage, and keyword-match semantics can align. Otherwise do not merge them and cap the outcome at uncertain. Never fabricate exact event boundaries.
• Read all seven signals together. Registrar concentration is a participant-diversity proxy, not registrant identity or participant count; interpret it with pattern, suffix, and time concentration.
• Compute each derivable signal a fixed, disclosed way so runs are reproducible: persistence as distinct active windows and busiest-window share; pattern concentration as largest-template share; low-base as a small-cohort flag. Read registrar concentration as the provider-reported largest-registrar and Top-3 shares from keywords_trends, without reconstructing missing distribution data. Show the underlying figures, never a bare "high / low", and do not switch measures between runs. A set low-base flag caps the outcome at uncertain.
• Thresholds are heuristic bands, not statistical laws; show the figures, treat edge values as uncertain, and only call a cutoff proven if a calibration record exists.
• Apply the fixed outcome order: brand-specific, uncertain, not validated, concentrated, then validated. Mixed evidence is uncertain.
• Record returned sample size, pagination, result cap, completeness claim, time window, observation date, and TLD / feed coverage. Partial ratios are observed-sample ratios, not population claims.
• Use one reproducible keyword-matching rule and exclude ambiguous segmentations from both cohort detail and candidate inventory.
• Keep full known-keyword intelligence in keyword-intel; do not duplicate search, advertising, supply, transaction, or catalyst analysis here.
• Do not surface candidates for a brand-specific keyword. A public-web collision check is not trademark clearance or legal advice.
• Verify lifecycle by stage: bulk_available only for registrability; confirm expired backorderability and provider; treat aged as a listing, not a sale. Surface options without recommending acquisition.
