Buying mistakes to avoid

Slow the click down before money leaves your account.

NST should help readers notice weak product pages before they buy. A good recommendation explains method, fit, limits and freshness before any retailer action.

01

Ranking without method

Ask what evidence, product facts or testing process actually supports the recommendation.

02

Retailer link before context

Read who the product suits, who should skip it and what the main limitation is before opening a retailer page.

03

Urgent sales language

Treat pressure phrases as a warning sign unless the page explains the evidence and trade-offs clearly.

04

Missing freshness signal

Look for when the product facts, evidence or affiliate link were last checked before relying on the page.

Help shape the review queue

Tell NST what to check next.

Use the contact route to suggest a product, comparison or buying question. Suggestions help prioritise the queue, but they never become affiliate recommendations until evidence, product facts and disclosure checks are complete.

Reader suggestions inform the research queue. They do not create an affiliate recommendation until the product, evidence and disclosure checks are complete.

How a product earns a place.

A smaller checked library is more useful than a long list of unverified recommendations.

  1. 01

    Evidence before links

    A product only appears after its identity and public claims have been checked and its editorial review is complete.

  2. 02

    Context before verdicts

    We explain who may find it useful, who may not need it, and what realistic alternatives exist.

  3. 03

    No stale sales claims

    We do not publish static retailer prices, ratings, review counts, discounts, or stock claims in product copy.
