Scoring methodology
A ranking is only trustworthy if the reader can check it. Here is the entire process, the scale and the weights we use.
A four-step process
- 1
1. Define the scope
Each ranking is limited to one concrete purchasing need and includes the providers a buyer in Vietnam actually meets while searching — national companies and local ones alike.
- 2
2. Collect public data
Sources are official websites, contact pages, product or project catalogues, warranty terms and whatever the company states about itself. Anonymous reviews are not used as a scoring basis.
- 3
3. Score each criterion
Each criterion is scored 0 to 10. A 10 means the requirement is fully met and verifiable; low scores usually reflect information that is not published, or a service that simply does not include that item.
- 4
4. Compute the total and rank
The total is the weighted average of the criteria, rounded to one decimal. Position follows directly from that number, with no manual adjustment.
Criteria and weights
Weights differ between rankings because buyers’ priorities differ. Within each ranking the weights always add up to 100%.
Ranking of website development companies in Vietnam
| Criterion | What we check | Weight |
|---|---|---|
| Engineering quality | Stack choice, real loading speed, room to scale, and whether source code is handed over. | 25% |
| SEO & Core Web Vitals | URL structure, structured data, correct hreflang for multilingual sites, Core Web Vitals. | 20% |
| Post-launch support | Response time, maintenance plans, and whether the client is locked into one vendor. | 20% |
| Track record | Years in business, published projects and breadth across industries. | 20% |
| Cost transparency | Itemised quotes, annual running costs stated upfront, no surprise line items. | 15% |
Ranking of translator device sellers in Vietnam
| Criterion | What we check | Weight |
|---|---|---|
| Warranty & after-sales | Published warranty term, return process, and who actually handles a faulty unit. | 25% |
| Hands-on trial | Whether there is a physical point where you can test the device in noisy conditions first. | 20% |
| Multilingual support | Buyers are often foreign residents or businesses serving foreign guests. | 20% |
| Catalogue & stock | Number of brands, price tiers and real availability. | 20% |
| Price transparency | Prices published on site rather than “contact us for a quote”. | 15% |
Three editorial rules
No guessing in place of data
If something is not published, we record it as “not published” rather than assuming. That may lower the company’s transparency score.
Scope is not a flaw
The “Worth knowing” section describes limits of applicability — no branch in central Vietnam, for instance — not an allegation about service quality.
A formula you can re-check
Every component score appears in the comparison table, so anyone can multiply by the weights and verify the total themselves.
Request a data update
Representatives of listed companies can send corrections with verifiable sources: registration documents, a warranty policy page, a new office address. We check them and update the scores if the facts have changed.
