How is a review carried out?
- 01We visit the business's public website as a customer would, on desktop and on a phone.
- 02We work through the five jobs using real products from the business's own range.
- 03We record what we find with dated screenshots and the pages checked, using four evidence statuses: Detected, Observed, Not found in this review and Not checked.
- 04Checkout and logged-in journeys are reviewed only where access is available and authorised.
- 05A reviewer checks the findings before anything is published.
What the score means, and what it does not
The Index score describes what a customer can do on a business's public website on the day it was reviewed. Each of the five jobs is scored out of 20, giving a total out of 100, using dated evidence that anyone can check. It does not rate the business, its products, its staff or its service, and it is not a measure of size or sales.
Who uses it
- Parts suppliers comparing their websites
- Garages and fleet buyers choosing suppliers
Why this matters for automotive & parts
A wrong part costs a garage time and a return. Clear fitment information is often what decides where the order goes.
How we keep it fair
- Every published review uses the same five jobs, from public evidence that anyone can check.
- Not found in this review means we looked and did not see it on the pages checked. It is not proof that a feature does not exist.
- Recommendations are hypotheses to test, not claims about lost sales.
- Existing iWeb clients are represented through a case study, not a public critique.
- If a detail is wrong, the business can tell us and we will check it.
Key terms
- Fitment
- Whether a part fits a given vehicle.
- Motor factor
- A trade supplier of vehicle parts to garages and the public.
