What is the average lifespan of a webpage?
The estimates vary, but they are all short. [Ironically, 2 of the 3 reports/ studies listed above had broken links and were no longer available. They had to be found using a web archive.]
Now, if webpages last 100 days or less before they are changed, deleted, or moved, what about all of the hyperlinks on webpages? In 2013, a study by Harvard University found that about 50% of all the hyperlinks included in Supreme Court decisions were broken (meaning the links no longer worked, or no longer directed you to the location they were supposed to).
