Thanks for the clue delivery of Coje_He, a netizen of IT Home!
On May 19, IT Home reported that the Internet is an unimaginable treasure house in modern life, but even if users around the world rely on the Internet every day to obtain books, pictures, news reports and other resources, these contents may eventually disappear from people's sight. The Pew Research Center published a study on the 17th local time and found that the current online content is still "fleeting".
Source Pixabay The researchers randomly collected about 1 million web pages from the archives of Common Crawl (an Internet archive service that regularly collects snapshots of websites at different time points). From 2013 to 2023, they took samples from the web pages collected by Coomon Crawl every year and checked whether these samples still exist at present.
According to the data, in 2013 25% will be inaccessible by October 2023 。 The results of these pages that cannot be accessed include two different situations: 16% of the pages are not in the domain name; The other 9% of the pages don't even have domain names.
Specifically, among the news websites sampled, 23% of web pages contain at least one invalid link High flow news websites and low flow news websites contain basically the same proportion of bad links. Among the top 20% of news websites with website traffic, about 25% of the pages contain at least one invalid link; Among the websites in the bottom 20% of website traffic, the data is 26%.
In terms of encyclopedia websites, the researchers chose the "reference link" part of Wikipedia. Of the more than 1 million reference links in total, 11% are no longer accessible ； 54% of Wikipedia page reference links contain at least one invalid link.
In terms of social networking sites, researchers published nearly 5 million samples of tweets on the social media platform X (Twitter) from March 8 to April 27, 2023, and tried to observe whether these tweets were still on the site until June 15, 2023. The study found that nearly 18% of tweets were almost invisible within three months. 60% of them are because the account is set as private, frozen or cancelled ； Forty percent of the accounts are deleted by the account publisher, but the account itself is still active.
