Use 1-click tools. There are browser extensions for Chrome and Firefox (and bookmarklets for other browsers) that make Perma.cc links with a single click. See perma.cc/settings/tools
Organize link information. To make it easier to identify the content you save, you can "Edit details" of the snapshots so that their dates and descriptions are clear. You can also create folders to keep your work organized and easy to review.
Uploads are an option. Occasionally you might want to upload a PDF, and Perma allows this.
Persistence is key. Pages that display data based on a search or a click can be tricky. Contact the library if you can't quickly get the Perma snapshot to match what you're trying to archive. We can help! refdesk@law.uci.edu
