A Nielson white paper shows that strong metadata, the information keyed into the system when books are first published, boosts book sales tremendously. Fiction in particular benefits from strong metadata because nonfiction works can usually be located by using title and category. Fiction needs more contextualization in the metadata to enhance search results.
If you’re confused about what metadata is or how to most effectively harness its power, check out Writer’s Resource’s metadata service. Know before you publish! Once the information has been keyed in, it can’t be changed unless a new copy is released.
