How we compiled this
Published self-serve USD pricing was collected by fetching each vendor's official pricing page directly (WebFetch tool). Where official pages rendered JS-only tables with no static price text, or geolocated to non-USD currency, pricing was corroborated and sourced from reputable 2026 pricing-comparison pages (GetApp, SoftwareAdvice, Backlinko, official vendor blog posts). SE Ranking's official page displays EUR; USD figures sourced from GetApp and SoftwareAdvice. Sitebulb's official page requires JS currency toggle to show USD; USD figures sourced from GetApp and SoftwareAdvice. Mangools' official page renders prices via JS; figures sourced from GetApp and SoftwareAdvice. Semrush's official pricing page rendered as JS-only navigation shell only; plan prices confirmed via Backlinko (updated Feb 2026) and SoftwareAdvice. Annual rates: where a vendor publishes '2 free months' (Ahrefs) the monthly equivalent is computed as (monthly × 10 / 12); where vendors publish an annual-savings dollar amount (Serpstat), the annual monthly rate is derived from (annual-total − savings) / 12; where only a percentage discount is stated, the monthly rate is not computed to avoid rounding ambiguity and annualDiscountPct is recorded instead. Quote-only / enterprise tiers are recorded with monthlyUsd null. All telephony fields (minutesIncluded, callsIncluded, overagePerMin, overagePerCall) are null throughout as this is a non-telephony vertical.
