What is Co-citation and Co-occurrence?

Co-citation is the presence of two different links, A and B, on a website (C), which means that the value of C will pass through to A and B. Co-citation also goes a step further to dictate that link A and B will form an interrelationship and pass some value by association to one another. Co-citation establishes a relationship between the A and B websites that aren't directly linked together, but do appear together on web page C.
