IANAL, but the short answer is you can't use US Copyright law to restrict how content is consumed. The limited protection given to authors by the law is to restrict what others can publish.

The law has been thoroughly litigated over web publishing and search engines so there is plenty of precedent to read up on if you want to understand why (short of a huge and super unlikely change to the laws) what you want can't (and shouldn't - the US Constitution created copyright in order to incentivize creators to publish their works instead of keeping them under lock and key) just search for things like [copyright and web search engines]:

If you want limitations that aren't implemented in copyright law then you'll need to only share your content to others privately and under a contract they've agreed to.
