Nearly every author imagines being interviewed on a television program as an exciting aspect of their book marketing campaign. As beneficial as these popular interviews seem, the truth is that there are more useful methods that have a more substantial impact on book sales. A perfect example is radio interviews: they can be conducted by phone, aren't time-consuming, and may bring impressive results. It is because radio interviews tend to be much longer than television interviews, and the audience pays more attention.

Attention leads to interest, making listeners more inclined to buy a book. Radio's longer interviews help by allowing authors to take questions from listeners via telephone, which helps to build keen interest with the audience. As book publicists tend to say, you never know who's listening. Many times, producers from other, larger shows have tuned in and later invited the author to appear on their show: One appearance leads to another.

Radio shows and hosts usually have dedicated fans who listen daily. Authors who build a good rapport with hosts leave the devoted listeners instantly impressed. That definite appeal carries over to the book, which naturally can lead to increased sales. Radio programs are designed for specific target audiences, and when your book's topic lines up with both the show and audience interests, it's a perfect match. When an interview is successful, the author is often invited back as a guest, which helps book sales.

Podcasts, which can be described as online radio shows, work similarly. Audiences may be smaller, but some podcasts worth the effort.  A podcast listener can check the author's website and social media, allowing a deeper connection and sense of involvement. Developing a sizeable digital following is an essential book-marketing tool, so building that following is vital. Book publicity requires reaching audiences wherever they are, and podcast interviews help expand every author's audience.
