sites show all six things buyers formally ask for (13 of 137).
19%
state their production capacity as a number.
23%
show no real photo of their own plant anywhere.
29%
of the 207 firms give a buyer nothing to check online.
Shares of the 137 Tamil Nadu manufacturer websites we read in full on 22 October 2026, unless stated.
A friend who buys machined parts for an OEM told me they no longer visit plants for the first cut. Sixty suppliers on a longlist get a few minutes each, and six make the shortlist. I've photographed Tamil Nadu plant floors since 2021, and I kept seeing capable plants described online with phone photos and a paragraph. So we stopped arguing the point and counted.
The finding
Buyers ask for proof. Nine in ten manufacturer websites don't show all of it.
No buyer scores the website itself; they score the proof. OEM quality teams, PSU tender committees, GeM and IPO reviewers all ask for the same things: photographs of the plant, capacity, machine lists, customers and certificates. The website is where a buyer who doesn't know you looks for that proof first, and it decides whether you make the list. Most manufacturers we read show some of it. Very few show all of it, and the missing pieces are exactly the ones buyers ask for by name.
01 · The requirement
What Buyers Formally Ask a Supplier to Show.
Tier-1 supplier quality (India)
A company profile with quality and delivery performance at existing customers, certificates and financial checks, then a one-day on-site audit with a pass mark of 75 out of 100.
Automotive supplier questionnaire
Main customers and their share of turnover, a machine list, test and metrology equipment, floor area, layout, certificates, shifts and headcount.
POWERGRID vendor approval
Photographs of factory, plant and machinery and testing facilities, a machinery list and a supply list.

BHEL vendor registration
A form scored out of 100 (60 to pass) on organisation, quality system and technical capability. Existing PSU approvals earn extra points.

EIL enlistment
A company profile with major clients, an organogram, three years of accounts and past purchase orders.

GeM seller registration
Database checks, then a third-party check of physical existence, capacity and process, including a live geo-tagged video assessment for manufacturers.
SME IPO investors
Product-wise installed capacity and utilisation, plant locations, accreditations and customer concentration, plus a lead manager’s site visit.

02 · Before contact
What the Website Does Before Anyone Calls.

92.7% of 151 manufacturers surveyed use supplier websites to learn about new suppliers.

The supplier that won was on the buyer’s first shortlist 95% of the time.
A typical B2B website visit is about two pages, at about 82 seconds a page.

54% of international buyers said suppliers they found online lacked product details and photos.
A note on the name: no published study measures how many minutes a buyer takes to judge a supplier. A first visual impression of a web page forms in a fraction of a second; a typical B2B visit lasts a few minutes. “The Four-Minute Plant” is the name of our argument, not a measured number.

How many of the six items each site shows.
The six: a real shop-floor photo, capacity as a number, a scale fact, a certification, customers, and an address. No site showed none. Only 13 showed all six. The item most often missing is capacity.
How the plant is shown.
Judged by hand from up to 40 of each site's largest images. In place of the plant we saw expo-stall photos, machine makers' catalogue cut-outs on “facilities” pages, stock refineries and handshakes, and on a few sites, AI-generated images.

homepages don’t say what the company makes on the first screen.
45%
offer a company profile or brochure PDF, the document every buyer files.
6%
mention an existing vendor approval, though BHEL awards points for one.
29%
have no dated content anywhere, so a buyer can’t tell the plant is still running.
18%
still carry template placeholder text somewhere on the site.
92%
are set up for phones and 96% use HTTPS. The basics are done; the proof is missing.
By sector.
Indicative only: pipes, valves and process equipment are small groups. Machine-tool and tooling firms show the least proof.
| Sector (sites) | Shop-floor photo | Capacity stated | Customers named | All six |
|---|---|---|---|---|
| Auto components (42) | 67% | 31% | 81% | 12% |
| Machine tools & tooling (61) | 59% | 8% | 31% | 5% |
| Pipes, valves & fittings (16) | 94% | 19% | 56% | 13% |
| Process equipment (18) | 78% | 28% | 44% | 17% |

05 · Method
How We Measured.
What this research doesn't show
- It shows what is missing, not what it cost. We have no data on deals won or lost.
- No buyer formally scores a website. Formal qualification runs on documents, audits and site visits; the website decides who gets that far.
- Proof doesn’t replace capability or price; it gets a capable plant into the room where those are compared. (82% of engineers call cost very or extremely important, and Japanese manufacturers in India cite missing capability more often than trouble finding suppliers.)
- The published buyer surveys are mostly from outside India. We found no Indian study of how buyers use supplier websites.
- The sample comes from industry member and exhibitor lists, not all Tamil Nadu manufacturers, and machine-tool firms are over-represented.
- Figures are floors: text inside images and PDFs was not read, and photo calls were made by one reviewer.
