If you're an author, and you share your book links, you usually copy the entire link in your browser address bar. Here is a way to makes the links smaller, and only will provide the information required for your particular link.
I've seen several long links not just in the spreadsheets that I've been sent, but also on websites and other places that books are listed. You may not even need to use a link shortener (like Bit.ly or other options).
I have created several different how to videos, and I found that this is important, and whenever anyone requests a new review, I have them also watch this video. Of course, you want the other videos, especially to see the links where your reviews (the ones you write) are posted so you can share them with the author (Just like I do now.)
Other how to videos can be found on Amy's Bookshelf Reviews and Amy Shannon's YouTube Channel at https://www.youtube.com/channel/UCIgDtOxWs1pJHHKoP_t9nQA
