Define the subject
Two values only support a meaningful comparison when the subject, units, method and conditions align. A table cell without those conditions may create a false impression of precision.
Locate the original
Start with the named publisher page and record the address. A search result excerpt is a route to a document, not a replacement for it.
Separate claim and observation
Write publisher descriptions as attributed statements. An image can identify visible branding but cannot establish internal construction, measured output or authenticity.
Name the unresolved field
A comparison can reveal a missing condition without selecting a winner.
