I use an index note to provide a summary of the experiments I've done along with note/hyperlinks. I accomplish this by creating an Excel table with the information I want and then copy-pasting the result into Evernote. I attach the source spreadsheet so that I can quickly add entries:
The hyperlinks are created in the spreadsheet using Excel's HYPERLINK("URL", "text") function. The URL to use for the "note" and "web" link are obtained via right-click->Copy Note Link and right-click->Share->Copy Note URL to Clipboard respectively.
