Is “deep linking” a copyright violation?
“Deep links” are web links that connect directly to a webpage without first stopping at the homepage of the company or organization hosting the webpage. Such links may upset commercial website owners because the links often bypass the advertisements and other identifying material on the owner’s homepage. To protect against claims of copyright or trademark infringement, it is important to set up your deep links so that it is clear to the user that the linked webpages are clearly separate from your own webpages. You may also want to consult the linking policy, if any, on the homepage of site to which you are linking. Here’s a helpful article about deep linking.
