So, now when you type in a fact on Google Search, the search will throw up additional information about whether or not the fact is true and who validated it.
Created to combat the spread of misinformation, the tool means that if users go hunting for facts in Google Search or via Google News then information from sites like Snopes will appear adjacent to the results.
The move extends a Google partnership with Jigsaw previous year that enabled publishers to identify and label articles with a fact-check tag.
Google said the label will be used to help readers make "informed" decisions on what to read and whether it can be trusted as a source of information.
The system is far from ideal, though. The information won't be available for every search result, and there may be conflicting conclusions in some cases, Google said in the blog post, from researcher Cong Yu and Justin Kosslyn of Google's sister company Jigsaw.
Google will now fact-check search results as part of a new worldwide initiative to combat the spread of fake news.
It's important to note that Fact Check doesn't affect the ranking of the articles in any way, nor does it flag sites which deal in satire, meaning users will still have to do their own investigative work to determine what's what. Sometimes fact-checkers from different organizations might reach different conclusions.
Minister: Iraq to boost crude oil production by year's end
Libya's Sharara oil field, the country's largest, resumed production on Sunday after a week-long disruption. OPEC ministers will meet in May to decide whether or not to extend the oil supply curbs beyond June.
To be recognised as a fact checker, sites will need to meet a rather long set of criteria.
The sites that appear in a search engine will be deemed authoritative by an algorithm.
The web search giant has now announced that it is rolling out the label across the world.
The new Google logo is displayed at the Google headquarters on September 2, 2015 in Mountain View, California.
Only publishers that are algorithmically determined to be an authoritative source of information will qualify for inclusion.
For example, if the query asks "Are 27 million people trapped in modern slavery?" and the claim states "Today 27 million people. are enslaved", the results will also serve up the person who made the claim, the organization checking the fact and the validity.
Google has also provided guidelines for publishers to fact-check public statement.
