This page explains how Coffee Mugs Online chooses topics and researches, writes, checks and updates its content.
Our purpose
We publish guides about coffee mugs, travel mugs and insulated drinkware for coffee and tea drinkers choosing mugs and travel mugs for home, work and travel. Our guides focus on comparing mug materials, capacities, lids, insulation and care requirements so readers can choose drinkware that suits how they drink.
How we choose topics
We cover the questions our readers need answered to make a decision or finish a task. Each topic gets one main guide, so we do not publish several near-identical pages on the same question.
How we research
- We base our guides on manufacturer specifications, care and use instructions, and official food-contact and product-safety resources such as the U.S. Food and Drug Administration (FDA) and the Consumer Product Safety Commission (CPSC).
- We separate facts, estimates and opinion. Facts and figures link to their source; estimates state their assumptions; opinions are labeled as our view.
- Where a guide covers safety, we link to the official source rather than restating it as our own advice, and we place warnings where readers will see them.
Research-based and hands-on content
Most of our guides are research-based: they compare published specifications, manuals and official guidance. If an article is based on our own hands-on use of a product, it says so and describes what we did. We never present research as personal experience.
What we do not do
- We do not invent test results, scores, star ratings, statistics, testimonials or reviews.
- We do not promise results, savings or performance that a source does not support.
- We do not publish hand-typed prices or “deal” claims, because they go out of date quickly.
- We do not accept payment, free products in exchange for coverage, or sponsored placements in our guides.
Safety-sensitive topics
Hot drinks can scald, and some mugs are not suitable for the microwave or dishwasher. Always follow the manufacturer’s care label. We do not make claims about lead or other contaminants unless an official source or the manufacturer documents them.
Affiliate relationships
We earn commissions from some links, as explained in our Affiliate Disclosure. Commissions never decide which products we include or how we describe them, and articles with affiliate links say so before the first link.
Updates and corrections
We review guides when products, specifications, rules or official guidance change, and we show the date a guide was last updated. Errors are handled as described in our Corrections Policy.
