If you do not already know, the Internet Archive‘s Wayback Machine is a service that crawls the internet and saves a cache of websites. This provides the ability to look at what a website used to look like. The problem is that smaller sites would only get crawled occasionally. The service is operated by a non-profit and they focused their limited resources on the most popular sites.
Well, now you can manually trigger a crawling of your website. Just look for “Save Page Now” on the website.
