SIFT is an evaluation method developed by Michael Caulfield, a digital literacy expert, from Washington State University, for assessing the credibility and reliability of online content. The SIFT methods can be used to evaluate different kinds of online information like social media, videos, images, news articles, scholarly articles, statistics, etc.

SIFT provides additional evaluation skills to build on approaches like the CRAAP and other checklist methods to evaluate online content.
Some questions you might ask using a checklist when initially looking at a web resource:
These types of questions are not sufficient. Why?
There's a theme that runs through all of these moves: it's about getting the necessary context to read, view, or listen effectively. And doing that first.
Who the speaker or publisher is, is one piece of context. What is their expertise? What is their agenda? What is their record of fairness or accuracy? To get at these answers, we investigate the source. Just as when you hear a rumor, you want to know who the source of it is before reacting to it; when you encounter something on the web, you need the same sort of context.
When it comes to claims, a key piece of context includes whether they are broadly accepted or rejected or something in-between. By scanning for other coverage, you can see the expert consensus on a claim, learn the history around it, and ultimately land on a better source.
Finally, when evidence is presented with a certain frame — whether a quote, a video, or a scientific finding — sometimes it helps to reconstruct the original context in which the photo was taken or the research claim was made. It can look quite different in context!
In some cases, these techniques will show you claims are outright wrong, or that sources are legitimately "bad actors" who are trying to deceive you. But even when the material is not intentionally deceptive, the steps do something just as important: they reestablish the context that the web so often strips away, allowing for more fruitful engagement with all digital information.
