How we test · Updated April 2026

The boring, reproducible way we run reviews.

Every product on tuto.digital goes through the same four-stage cycle: retail purchase, real-world testing, weighted scoring, and quarterly re-checks. No press accounts, no embargoed previews, no "best of" lists written from press kits. This page is the full recipe — bookmark it, audit it, share it with your skeptical friend.

The four-stage process.

Ten days, in order, every time. We don't publish until all four stages are signed off.

01
Days 1 · Buy

Retail purchase

We buy the product like any reader would — on the cheapest 24-month plan, from the same checkout page, paying the same renewal price.

  • No press accounts or media keys
  • Cards billed to the editor's name
  • Receipts archived for audit
  • If a discount requires email signup, we sign up
02
Days 2–8 · Test

Real-world testing

Seven days of timed tests against a fixed protocol. Same machine, same time-of-day windows, same 12-city speed grid for every VPN.

  • 120 speed runs per VPN across 12 cities
  • Streaming on Netflix, BBC iPlayer, DAZN, Disney+
  • DNS, IPv6 and WebRTC leak audits
  • Customer support stress-test (3 tickets, 3 channels)
03
Day 9 · Score

Weighted scoring

Six-axis weighted formula applied to raw test data. Score is set before the editor checks whether the product has an affiliate program.

  • Speed, security, streaming, price, support, devices
  • Each axis 1–10, weighted (see block below)
  • Two-editor sign-off on the final number
  • Verdict locked before linking
04
Day 10 · Publish

Publish & re-check

Review goes live with full disclosure block, byline, and date. Calendar reminder set for the next 90-day re-check window.

  • Affiliate disclosure on every page
  • Author byline + last-updated date
  • 90-day re-check on price & specs
  • Major changes trigger a re-test, not a patch
The score formula

Six axes, weighted.

Every review is scored 1–10 across six axes. Each axis is weighted by what real users actually care about — not what the product team wants to brag about.

The weights below are the VPN formula. Hosting and AI use different weights, published on each category's methodology subpage.

final = (speed · 0.20) + (security · 0.20) + (streaming · 0.15) + (price · 0.15) + (support · 0.15) + (devices · 0.15)

Independence & funding

How we make money — and what we refuse.

tuto.digital is funded by affiliate commissions. When you click a "Get deal" button and subscribe, the provider pays us a percentage. Crucially: commission rates do not influence the verdict. We score before linking, and two of our top-rated VPNs (Mullvad, IVPN) don't pay anything.

Below are the specific things we don't do — published so you can hold us to them.

Sponsored placements

No brand has ever paid for a verdict, ranking position, or "homepage feature." If a product is on this site, it earned its spot.

Never offered, never accepted
Embargoed previews

Pre-launch access conditional on a positive review is a red flag. We wait for retail launch and buy the product like everyone else.

Politely declined, every time
Ghost-written content

Every review is written by a named editor who personally tested the product. PR-supplied "draft articles" go straight to the trash.

No exceptions
Commission-weighted rankings

The score determines the ranking. Not the affiliate program. Not the "partner tier." Not the cost-per-acquisition.

Score first, link second

Found a flaw in our methodology?

Methodology is a living document. If you've spotted something we've missed — a leak test we should run, a vantage point we should add, a category-specific check we're not doing — we genuinely want to hear it. Tipsters and auditors get a personal reply.

"If a review can be written without ever opening the product, it's not a review. It's a brochure." — Mert Kaya, senior editor
