A creator found her article on another site, word for word, with her name removed and a different date on it. The copy was newer, but the date on the copy was older, because the copier had set the date back. She had the original file on her computer, with a creation date, but a file on her own computer is not proof. Anyone can change a file date. She needed a timestamp from a source she did not control, and she had one, though she did not know it yet.
The proof was in the Wayback Machine. The Internet Archive has been crawling the web since 1996, and it has saved more than 890 billion pages. Her article had been captured three times, and the earliest capture was two weeks before the copy appeared. That capture was the proof. It was not her word against theirs. It was an independent archive, with a date, showing the page as it existed on that day.
The Wayback Machine saves snapshots of pages as its crawlers find them. A snapshot shows the page as it existed on the capture date, with the content, the images, and the links as they were. The earliest snapshot of a page proves the page existed at least by that date. It does not prove the exact launch date, because the page could have been live before the first capture, but it proves a date, and a date is what a dispute needs.
The snapshots have been used as evidence in trademark, domain, and copyright disputes, and courts have accepted them. The reason is the independence: the archive is not controlled by either party, and the capture dates are not set by the page owner. A snapshot is a third party saying the page looked like this on this day, and that is a stronger statement than any file on your own computer.
Anyone can request a capture. The Save Page Now feature lets you submit a URL and have it archived immediately, which is the single most useful habit a creator can build. Publish a page, save it to the Wayback Machine the same day, and you have a timestamp that does not depend on your own records. It takes thirty seconds, and it is free.
The archive has limits, and they matter. A page that was never captured has no snapshot, and no snapshot does not mean the page did not exist. It means the crawler never found it, or the page was blocked by robots.txt, or it sat behind a paywall or a login. A creator whose pages were never captured cannot use the archive, and that is a reason to request captures rather than waiting for the crawler to find the page.
The archive also captures what was public. A page that changed after the capture will show the old version in the snapshot and the new version live, and the snapshot will not reflect the change. That is usually a strength, because it preserves the original, but it means the snapshot is a record of one day, not of the page's whole history.
The strongest proof is not one timestamp. It is three, from three sources that do not depend on each other. The Wayback snapshot is the first. The search engine's earliest index date is the second, and it can be found by searching for the page's distinctive phrases with a date filter. The third is the platform's own record: the publish date in the content management system, the version history, or the email notification that went out when the page was published.
None of these is perfect on its own. Together they form a timeline that is hard to dispute, because it would require three independent systems to be wrong in the same direction. When a copier sets a fake date, the timeline is what exposes it. Build the timeline before you need it, by saving each new page to the archive on the day it goes live, and the dispute, when it comes, will be short.

Yes. The Internet Archive has been crawling since 1996 and has saved more than 890 billion pages. The earliest snapshot of your page proves it existed at least by that date, and courts have accepted snapshots as evidence in trademark, domain, and copyright disputes.
No. It shows the page existed at least by the capture date, not the exact launch date, because the page could have been live before the first capture. For a dispute, a date that precedes the copy is usually enough.
Then there is no snapshot, and that does not mean the page did not exist. It means the crawler never found it, or it was blocked by robots.txt or behind a login. Use Save Page Now to request a capture for every new page on the day it goes live, so the record exists before you need it.
The search engine's earliest index date, found by searching for the page's distinctive phrases with a date filter, and the platform's own record, like the publish date in the content system or the version history. Three independent timestamps form a timeline that is hard to dispute.
