Always add a picture of the author. It makes the interview visually appealing and emphasizes who is being interviewed. If I pulled up an interview of Tom Clancy, I am more likely to read it if I see a picture of him. It gives it an air of legitimacy. Ask the author for a picture or pull one from their website. Some don’t like to give pictures of themselves for some reason or another.
Make sure you add a picture of the cover of the latest book the author has published or the one you are interviewing them specifically about. This shows the reader what they wrote and can pique interest in the book which is one purpose of conducting the interview.
Author Guest Post
Contact the author and see if he is willing to write a guest post. You can choose a topic based on his book or something that is more generic for writers. This can give the readers even more insight into the author and generate more attention for his book.
Add a review of their book. This helps the author even more as mentioned above under author guest post, but it also gives you even more credibility. When a reader sees that you not only have taken the time to interact with the author and help him, you also read the book and are still willing to help out. That means you didn’t hate the book or would recommend people to avoid it.
Add links to the author’s sites. That includes their website which most authors do have. If they don’t, suggest strongly that they get one up as soon as possible. Share links for all social networking sites such as Facebook and Twitter. If they write regularly on other sites, share those as well. You want to help the author as much as you can.
