METHODOLOGY · VERSION 0.1

A ranking you can
inspect and challenge.

E-commerce Index separates directory coverage, technical observation and commercial popularity. Today’s score measures a small set of public website signals. It is not a traffic, revenue or customer-satisfaction estimate.

Published15 July 2026StatusEarly public methodology

The essential distinctionBaseline means an editorial seed value awaiting measurement.Observed means our crawler measured the public homepage.Verified will mean selected facts were confirmed by an authorized business representative.

Technical score v0.1 is a 0–100 homepage health score. Once a website is observed, its earlier baseline is replaced with the following reproducible calculation.

35Homepage availabilitySuccessful public response

15HTTPSEncrypted connection available

20Response timeUp to 20 points; one point removed per 250 ms

10Page titleNon-empty HTML title detected

10Meta descriptionPublic description metadata detected

10Product schemaProduct, Offer or ItemList structured data detected

score = availability + HTTPS + speed + title + description + commerce schema

Speed points are calculated as max(0, 20 − floor(response_ms ÷ 250)). Scores are capped at 100. Ties are ordered alphabetically.

Current limitation

One server-side homepage request cannot describe checkout quality, mobile usability, delivery experience or business popularity. It is useful as a technical observation, but it is not yet a complete commerce index.

One global measurement standard

The active scoring formula is applied consistently across country indexes. Local categories and market context can differ, but a technical signal has the same definition and weight wherever it is observed.

Public evidence only

Our crawler requests the public HTTPS homepage, follows redirects, reads at most 512 KB of HTML and stops after a bounded timeout. It does not sign in, add products to a cart, place orders or attempt to bypass access controls.

Versioned observations

Each observation stores the time, response status, response duration, detected metadata and the score produced by that methodology version. A refreshed observation can move a score in either direction.

Coverage before confidence

Global methodology does not imply a single worldwide leaderboard. Rankings are published within countries and relevant categories only when coverage is broad enough. We disclose tracked and observed counts, and retain the prototype label while most entries remain baselines.

03 · RESEARCH DIRECTION

Commerce Index v0.2

This is a proposed framework, not the formula currently used on store profiles. We will validate weights against collected data and publish changes before activating them.

25%

Reliability & safety

Availability over time, HTTPS behavior and carefully selected public security controls.

20%

Real-user experience

Mobile LCP, INP and CLS from eligible Chrome UX Report data, with lab data labelled separately.

20%

Commerce readiness

Product discoverability, working catalogue signals, structured product data and transparent policies.

15%

Discoverability

Indexability, metadata, canonicals, sitemaps and durable category/product information architecture.

10%

Operational trust

Visible contact, returns, delivery and privacy information—not subjective reputation claims.

10%

Data quality

Observation freshness, repeatability, coverage and owner-verified facts, with explicit confidence.

Popularity will remain separate.

Traffic or market-reach rankings require sufficiently representative, country-level evidence. We will not reverse-engineer visits from technical signals or mix self-reported analytics with unverified estimates. If introduced, popularity will be a separate dimension with its own confidence and methodology.

Commercial customers, affiliates and perk partners receive no ranking advantage.
Methodology changes receive a version number and publication date.
Material corrections retain an audit trail rather than silently rewriting evidence.
Websites may request a refresh or factual correction, but cannot purchase a score.
Missing data is shown as missing; it is not silently converted into a positive result.
Country and category comparisons use the same active formula and observation window.
