# Citation Checker
> Sales pages often list references to look credible. Learn how to check whether a citation actually supports the claim next to it.

## Guides
- [Why a Reference List Is Not Evidence](https://citations-on-supplement-sales-pages.pages.dev/reference-list-does-not-equal-evidence/): A tidy list of references can look like proof, but the reference list does not equal evidence. It only shows that the seller pointed at something.
- [Checking a PubMed Link in Two Minutes](https://citations-on-supplement-sales-pages.pages.dev/checking-a-pubmed-link/): Checking a PubMed link takes about two minutes: open it, read the title, the abstract and the type of study, then compare them with the sentence the seller.
- [When the Cited Article Is About Something Else](https://citations-on-supplement-sales-pages.pages.dev/cited-article-about-different-topic/): A cited article about different topic is one of the most common weak spots on supplement pages: the paper exists and is real, but it studied something other.
- [Review Article vs Original Research](https://citations-on-supplement-sales-pages.pages.dev/review-article-vs-original-research/): A review article summarizes what other researchers have published, while original research reports a new study with its own participants, methods and results.
- [Journal Quality Basics for Beginners](https://citations-on-supplement-sales-pages.pages.dev/journal-quality-basics/): A journal's name can hint at how carefully a paper was handled, but it cannot tell you whether a supplement works.
