Today I’m going to write about the Wayback Machine. This is a service that can give you a smile on your face or it can be your nightmare. Wayback Machine is a service that gives you the ability to browse through the archives of individual websites at specific times in the past, starting in 1996. It currently contains over 240 billion individual websites, as well as several special archives such as The September 11, 2001 collection, and is, therefore, an inexhaustible source of information for various research, seminar, graduate and other types of work.
By simply typing the URL in the provided field, you can search the archive of web pages, giving you a timeline showing the archived changes over time. Also, if a webpage was unavailable or displayed 404 during your daily surfing, you can copy the URL of that web page to the Wayback Machine and see the archive of the content you want, if any.
There are numerous ways you can use the Wayback Machine. A web designer can see what a client’s website looked like earlier to avoid repeating some elements while someone else when starting a business can see what the competition has been doing online as they have communicated their message in the past.
Pro Tip: If you want to see a list of all the individual web pages of a URL, then add an asterisk to it, for example, example.com *
It’s important to know here that it takes between 6 and 14 months from the time the content is indexed to its appearance in the Wayback Machine archive.
When can the Wayback Machine become your nightmare and how to prevent it?
As soon as you no longer want the content to be available, archived, and when you have previously removed the spam from search results using Google, Wayback Machine may become your nightmare.
There are two possible ways you can remove already archived content or prevent it from archiving.
If you are a web site owner, you probably know what robots.txt is and it will help you in removing previously archived content and preventing it from being archived further. With robots.txt, you can block access to a domain, folder, single page, or document.
If you are not the owner of the website then you are left with the possibility of sending an e-mail query with the specified links that you want to remove from the archive.
With a great deal of security, you can expect the Internet Archive to meet your request, as they say:
“The Internet Archive is not interested in offering access to websites or other Internet documents whose authors do not want their materials in the collection.” – Source
