What does The Index measure?
Five jobs a customer needs a website to do. Each is scored out of 20, giving a total out of 100. For automotive & parts, the journeys can include:
1. Find the product
Vehicle lookup and part-number search that lead to the right range.
2. Choose the right one
Fitment notes, diagrams and attributes that confirm compatibility.
3. See the price and availability
Trade or retail prices with branch or delivery availability.
4. Buy it
Ordering for delivery or collection, on account or by card.
5. Buy again and self-serve
Order history, returns and account tools online.
How is a review carried out?
- We visit the business's public website as a customer would, on desktop and on a phone.
- We work through the five jobs using real products from the business's own range.
- We 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.
- Checkout and logged-in journeys are reviewed only where access is available and authorised.
- A 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.
