Comparison Methodology
A public record of how Fridgeful chooses comparison sets, weighs grocery label evidence, handles availability caveats, and corrects published memos.
Commercial boundary
Fridgeful does not sell links, paid placements, or ranking positions. Outreach may request corrections, source context, or interviews, but paid link arrangements are out of scope.
Method
How rankings are produced
Define the shopper question
Each memo starts with a specific grocery decision, label claim, or comparison set. The article must be useful for a shopper, not only for a search query.
Set an eligibility gate
The ranking rubric states what a product must be able to show before it can be compared. Exact-carton evidence is preferred, but broad retailer or company evidence is labeled when exact proof is thin.
Score public signals
Rubric weights are visible in each article. Scores summarize public evidence across certification, label specificity, traceability, availability, and price/value signals when relevant.
Separate evidence from claims
Fridgeful does not treat marketing copy as proof by itself. Regulatory definitions, certifier standards, retailer standards, public filings, product pages, and source-dated disclosures are weighted differently.
Preserve caveats
Availability notes do not imply local shelf stock. Rankings are not health, safety, taste, or nutrition claims unless an article cites a direct source for that specific point.
Corrections and updates
Each article carries a modified date. Corrections should preserve the original evidence trail, add the new source or clarification, and update the article's modified date, data table output, RSS, sitemap, and AI manifest through the SEO artifact generator.
