Interpretation notes
domain_renew is treated as the strongest observable proxy for retention (customers paying to keep domains).
domain_create is interpreted as attempts/interest rather than confirmed purchases.
Transfer flows are used to decompose domain base changes: ΔDomains ≈ organic_growth + net_transfers, where
organic_growth ≈ ΔDomains − net_transfers.
Domains over time
Absolute daily domain count attributed to the registrar (stock variable from daily_stats).
Step changes often indicate portfolio migration or acquisition.
Market share over time
Daily market share (%) = registrar domains / total .cz domains. Normalizes out overall market growth.
Retention signal: domain_renew (daily)
Daily renewal operations (flow). Aggregates to window totals and supports renewal-intensity comparisons.
Acquisition vs interest (daily): contact_create vs domain_create
contact_create approximates onboarding/new customer objects; domain_create captures attempts/interest. Ratios may exceed 100% due to decoupling (pre-created contacts, reuse, API workflows).
Transfers: gain / loss / net
Migration signal based on registrar-to-registrar moves. Loss is negative; net = gain − loss.
Daily change (first difference): ΔDomains(t)
ΔDomains(t) = Domains(t) − Domains(t−1). Highlights shocks, step changes, and high-volatility periods.
Monthly renewal share vs last-year domain base (100% stacked)
For each month, we compare domain_renew to the registrar’s average domain base in the same calendar month one year earlier.
The stacked view estimates “renewed” vs “not renewed” share relative to that last-year base (capped at base for visualization).
Important: this does not account for multi-year renewals (renewing for multiple years reduces observable renewal operations later),
therefore this is a comparative proxy, not a true renewal rate.
Monthly: Renewals / last-year base (%)
Renewal intensity expressed as percent of last-year monthly base:
100 × domain_renew_month / avg(domains_month_(t−1y)).
Can exceed 100% due to operational effects (including multi-year renewals and data decoupling).
