Why do news headlines change after publication?
A headline you saw an hour ago can read differently now. There are five common reasons, and only one of them involves a mistake.
1. The story moved on
Breaking news is published early and filled in as facts arrive. "Road closed after serious crash" becomes "Arrest made after woman struck on bypass" once police release more. This is the most common reason by far, and it is what newsrooms are supposed to do.
2. The outlet was testing headlines
Many news sites show different readers different headlines for the same story, measure which one gets more clicks, and keep the winner. This is called headline A/B testing. The New York Times has described running tests on its homepage in which half of readers see one headline and half see another for about half an hour, after which it uses the one that drew more readers. ProPublica reported that the New York Post tested between two and five headlines per story the same way.
It is widespread. A study by Northwestern University researchers working with the analytics company Chartbeat examined 141,000 headline tests run by 293 news websites, and found winning headlines lifted click-through rates by more than 20%.
If you saw one headline and a friend saw another at the same moment, a test is the likeliest reason. Testing can also make a headline appear to switch back and forth when someone checks the page several times.
3. The headline was written for a different place
A story can carry several headlines at once: one on the article page, one on the homepage, one that appears when the link is shared on social media, and one written for search results. They are often worded differently on purpose. A headline you saw in a social post may never have appeared on the article itself.
4. Editors had second thoughts
A headline may be rewritten because it overstated the story, used a loaded word, was unclear, or drew complaints. These changes are judgment calls rather than corrections of fact, and outlets differ on whether they mention them.
5. The headline was wrong
When a headline states something false, such as a wrong number, the wrong person or the wrong outcome, the standard practice is to fix it and add a correction note saying what was wrong. How corrections are supposed to work.
How to tell which one you are looking at
- Did the story itself change too? New paragraphs and new facts alongside the new headline usually mean the story developed.
- Did the headline change back? A switch followed by a return to the earlier wording points to a test.
- Is there a correction note? If the headline contained a factual error, there should be one.
- Is it the social headline or the page headline? Compare the link preview with the headline on the article.
How NewsFacts treats headline changes
We record the headline on the article page and the headline supplied for social sharing separately. When a headline returns to wording the story carried earlier, we label it "Headline switched back" and don't list it as a rewrite, because it is usually a test. On our first day of collecting, one story's headline switched back and forth four times. How our labels work.
