What a missing fact usually tells you
Absence is information, and it is the part of a page that is easiest to skim past.
Read a product page for what it says and you will learn what somebody wanted you to know. Read it for what it declines to say and you learn something less curated. Sellers are not obliged to publish every measurement, and the ones they publish tend to be the flattering ones. So when a page describes size in three different ways but never states weight, or lists everything except how long a consumable lasts, the omission is worth noticing. It does not prove anything. It simply tells you which question to ask before you commit.
Build a short list of the facts that matter for your problem, and check the page against your list rather than reading the page and letting it set the agenda. Dimensions, weight, what is included in the box, what has to be bought separately, what the running requirements are, whether parts are available. If a fact on your list is absent everywhere you look, that pattern is itself worth respecting: some things are hard to find out because they are not selling points. Asking the seller directly is reasonable, and the quality of the answer, including how long it takes and how specific it is, tells you something in its own right.
The same reading applies to language. A description tells you what something is. A claim tells you what it is meant to achieve, and claims are often written to sound like descriptions. Phrases built to impress rather than inform tend to avoid anything checkable, which is exactly why they feel smooth to read. When a sentence would be difficult to prove wrong, treat it as atmosphere. Australia has consumer protections covering how products are described, and and the relevant consumer authority is the place to check what those protections require.
