Research Methodology

1. The question comes first

Informational pages start from a question people actually type, measured rather than imagined. We use keyword tools to establish that demand exists and roughly how much. A topic with no measurable demand does not get written up merely because it interests us, and a topic with demand does not get written unless we can source it.

2. Sources are fetched and read, not recalled

Every figure on a factual page is read from the source document when the page is built, and the date it was read is published on the page. Nothing is written from memory, and no number arrives here via another blog that cited a bulletin.

3. Claims are attached to sources, individually

A source record lists the specific claims it supports. That is more work than a bibliography, and it is the difference between knowing a page has sources and knowing which sentence rests on which one. When a source is revised, the affected sentences are identifiable rather than a re-reading exercise.

4. Products are verified against the marketplace

Recommended products are checked programmatically against live listing data, for three things that fail independently:

• Identity — is the linked item still the product we describe? A working link can point at an accessory, a different pack size, or an unrelated item.
• Availability — is it actually purchasable, or listed with no offer?
• Price — does the figure we print match what is charged?

5. Automated checks before anything ships

A page has to survive gates that run against the live site, not a local copy. Among them:

• No safety claim without a primary source
• No affiliate link without a disclosure rendered before it
• No product in a ranking that cannot currently be bought
• No printed price that disagrees with the marketplace
• No prose claim that contradicts our own product data
• No page published without inbound links from its topic cluster

Each of these exists because it caught a real defect on this site, not as a statement of intent.

What this process does not give you

It does not make us a laboratory. We do not run comparative durability testing, and where a specification is the manufacturer's claim we label it as such rather than presenting it as a measurement. It also does not substitute for a professional looking at your specific installation, which is why several pages here end by telling you to call one instead of selling you something.
